The highest quality heating batteries. How to choose a heating radiator - types, characteristics, comparison of options

The choice of heating batteries is a serious undertaking, on which not only the efficiency of heating residential premises depends, but also the operational life of the heating system as a whole. In multi-apartment buildings, the risk of water hammer is higher than in private houses, which is due to their connection to a centralized heating network. Therefore, the article will examine in detail the question of which heating radiators are best for an apartment.

The supply of coolant to the apartments is carried out through connection to a centralized heating network (DSN). The movement of coolant in such systems occurs in a forced manner. Liquid is supplied to each apartment using special pumps that are part of the DSP. The pressure pumped by the pumps averages 16 atmospheres.

Helpful information! When choosing a heating radiator, it is first recommended to pay attention to how often pressure surges occur in the communications. In order for the battery to withstand water hammer, its material must have a sufficient margin of strength.

A fairly common phenomenon that affects centralized communications is a violation of conservation. Typically this happens in summer period time. However, not all batteries are able to withstand the water hammer that occurs during such depressurization in the system.

Individual elements of the DSP wear out greatly over time, which entails a deterioration in the quality of the coolant and the ingress of various foreign impurities into it. These can include technical impurities, particles of rust, dirt and various sedimentary elements. The presence of the former in the working environment negatively affects its thermal output during circulation through the DSP. The rest contribute to the narrowing of the clearance of pipes and radiators, which also reduces the efficiency of heating residential premises.

When replacing heating device In the apartment, you should check the compatibility of the materials from which the batteries and connecting elements (fittings) are made. The incompatibility of metals leads to their oxidation, which often becomes the cause of emergency situations in the central heating plant.

Which radiator to choose: types of heating batteries

Today you can find a variety of batteries for installation in apartments. All of them are divided into types according to several criteria. First of all, all heating radiators are classified according to the material from which they are made:

• cast iron;
• steel;
• aluminum;
• bimetallic;
• copper.

And also, depending on the design, they can be:

• sectional;
• panel.

Each of the above types of heating devices is suitable for use in certain conditions. It is also worth saying that there are highly specialized models that are used to perform one function. This type includes convectors floor type, used in rooms that have a large glass area. Their use eliminates the possibility of windows fogging up.

You can also find another type of convectors on the market – baseboard ones. They are installed in special metal boxes that replace classic skirting boards. The main advantage of such heating devices is that they do not violate general interior rooms.

Today you can find a variety of batteries in terms of design. Range modern radiators heating options are incredibly wide and varied. The disadvantage of batteries made in a unique design is their price. Therefore, such heating devices are not in high demand.

Characteristics of cast iron batteries for an apartment

Not so long ago, cast iron heating appliances were the most popular and were used almost everywhere. But today these bulky structures covered with enamel paint have faded into the background. With the development of production technologies, more efficient and wear-resistant steel radiators, as well as devices made of other materials, have appeared.

Note! Cast iron material has a high thermal conductivity coefficient. It’s also worth saying that it takes a long time to heat up, but at the same time it also takes a long time to cool down.

Cast iron batteries can withstand quite high pressure (up to 30 atmospheres), which exceeds standard DSP indicators by 2 times. Thus, devices made from this material are highly resistant to water hammer in the system.

Among the advantages radiator batteries cast iron can also be distinguished by the fact that they are compatible with pipes and fittings made of other materials. This allows you to save money, since when replacing the battery there is no need to replace associated communications.

And also products made of cast iron are distinguished by their resistance to destructive corrosive influences. They are unpretentious regarding the quality of the work environment that moves through them. Long-term interaction of the inner surface of a battery made of cast iron with water leads to the formation of a dark sediment, which has an antioxidant property. Therefore, with normal use of such radiators, they can last for decades.

Modern radiators made of this material are coated with a special protective enamel at the production stage. Unlike old cast iron batteries, new models do not require annual painting, and are also easy to clean, as they have a smooth, glossy surface. Among other things, cast iron heating devices do not accumulate gases, so they do not need to bleed off excess air.

During the Soviet era, such radiators were manufactured in large quantities and had standard sizes. Today the lineup of these devices, offers customers virtually unlimited options for cast iron products, which differ in shape, design and color. A wide range allows you to increase the operational area of ​​​​such radiators.

Western companies engaged in the production of cast iron radiators produce special designer lines of heating devices. Such batteries are made in a fashionable retro style and are equipped with various ornaments. Of course, the cost of such products is an order of magnitude higher than conventional cast iron ones, but their quality and presentable appearance are beyond doubt.

Cast iron structures are selected depending on the size of the room. If necessary, the number of sections can be increased or decreased, which is very convenient. Let's consider what factors influence the choice of the number of sections:

• room area;
• window size;
• Number of doors;
• features of the climatic region.

Cast iron structures also differ in filling volume. For example, in domestic radiators it is 1.3, and in foreign ones - 0.8 liters. The cost of the latter is approximately 2-3 times higher. Brackets are used to install radiators in an apartment made of cast iron. It is also worth noting that some models are attached directly to the floor.

Why it is better to refuse to buy cast iron: a review of the disadvantages

As mentioned above, cast iron radiators are no longer as popular as they used to be. This is due to their shortcomings. The main disadvantage of these products is their heavy weight, due to which their storage, transportation and installation are accompanied by certain difficulties.

Note! To fasten a standard cast-iron structure, it is necessary to use bulky fastening elements - brackets.

It is also worth mentioning that, from a design point of view, standard cast iron products are not very presentable. They are absolutely not suitable for premises designed in modern style. Another disadvantage of heating batteries made of cast iron is low inertia. With such a battery it will not be possible to quickly regulate the temperature in the room, and for autonomous heating systems this property is especially important.

Cast iron structures do not differ in strength characteristics and are especially susceptible to mechanical stress (shocks). It is precisely because of the above properties that these products are not in great demand for modern market heating equipment.

Types of steel heating radiators for apartments

Steel radiators are one of the most popular today. They are distinguished by a lot of positive qualities, and are also quite presentable and fit almost any room design.

There are three main types of these products, which differ from each other in their design:

• panel;
• tubular;
• lamellar.

Each of these types fits certain conditions and has its own advantages and disadvantages. In order to answer the question of which heating radiator is best to choose for an apartment, it is necessary to consider the features of both panel and tubular, as well as convector structures.

Which heating radiators are best for an apartment?: steel panel batteries

The panel structure includes two steel sheets. By stamping they are given the required shape. After this, the resulting blanks are joined by welding, which makes it possible to obtain a hollow panel. If necessary, it is supplemented with convectors, thanks to which the air moves in a vertical direction. This allows you to create a kind of “barrier” that protects the room from the cold emanating from the window.

After assembling such a radiator, it is painted. The protective coating is very important element design, as it protects it from corrosion, makes it more presentable, and also facilitates its care. When choosing a new steel battery, you need to pay attention Special attention on how evenly the paint layer is applied to the panel. It must not contain gaps, cracks or chips.

Steel structures can withstand operating environment temperatures up to 95 ºC. They are designed for the standard pressure that is created inside the DSP, namely 16 atmospheres.

Helpful information! Steel batteries of this type can have a different number of convector elements and panels.

The length of such radiators ranges from 40 cm to 3 m. The minimum height of such a design is 20 cm, and the maximum is 90. Some companies are engaged in the production of steel heating devices of this type to order, which also expands their model range, and, accordingly, operational sphere.

Description of the operating principle, comparison of heaters. Review of types, companies and prices of convector heaters.

Depending on where the heating device will be connected to the pipe, there are two main options for steel devices:

• with bottom connection;
• with side connection.

When choosing a steel radiator, you need to pay attention to the location of the heating pipes in your apartment. Based on this, it is selected required design, With the right option connections.

Advantages and disadvantages of steel panel radiators

In order to answer the question of how to choose a heating radiator for an apartment, you need to familiarize yourself with the pros and cons of steel panel structures. Such models are the most common today. First, let's look at the positive qualities of these heating devices.

The first and perhaps most important advantage panel design - ease of installation. Installation into the heating circuit is done according to the instructions quite quickly. If necessary, you can do it yourself. In addition, the design of the radiator eliminates the need for assembly, as it is one-piece, which also saves time.

Panel radiators are highly inert, so they warm up very quickly. Thanks to this, they are easy to adjust to the required temperature. And also such steel structures They have a fairly large area, which contributes to quick and efficient heating of the room.

Steel batteries in the form of panels are compact in size and have an attractive, modern appearance. Such models are most suitable for apartments equipped with an autonomous heating system. This is due to the fact that a minimum amount of coolant is required to fill them.

Like any other product, steel panel batteries have their drawbacks. The main one is that they are not designed to withstand strong hydraulic shocks. They are reliable only when normal indicators pressure in the central heating system. However, this problem can be overcome. When installing a panel structure in an apartment, it is recommended to use special device– gearbox. This device allows you to reduce the level of load on the panel during water hammer.

The internal walls of such radiators, as a rule, are not equipped with special protective coating from corrosion. It follows from this that their shelf life will depend on how high-quality the coolant circulates through them.

Tubular (sectional) steel batteries

Unlike the previous type of steel radiators, these batteries include several sections. These elements are fixed to each other by welding. Such products do not require assembly, which is undoubtedly their advantage.

Note! How to choose a tubular type battery? Before purchasing a tubular heating device, an obligatory item is the selection of the required power. This indicator is calculated taking into account the total area of ​​the room that the sectional model will heat.

Sectional heating devices are used in systems whose pressure ranges from 8 to 10 atmospheres. As a rule, this is not enough for apartment buildings heated by DSP. Therefore, experts recommend that when using such models, purchase a gearbox that can protect the tubular battery from water hammer.

The standard wall thickness of sectional gearboxes is 1-1.5 mm, so they have a high inertia coefficient. But the small thickness of the walls is also a disadvantage of such products, since they are characterized by rather weak strength characteristics.

Tubular-type structures are characterized by good resistance to contaminated coolant environments. Unlike panel models, their internal surface is equipped at the production stage with a special protective layer of polymer material. Thanks to this, they are resistant to corrosion and have a longer service life.

Such devices are available in different sizes. The width depends on the area of ​​the room and the number of sections. The height can vary from 0.2 to 2.5 m, and the depth from 10 to 25 cm.

Sectional products have two main disadvantages:

• low heat transfer coefficient;
• the presence of welds that are unstable to hydraulic shocks.

Thus, sectional batteries are a good option for installation in autonomous heating systems. However, they are not entirely suitable for use in DSP conditions, as they are susceptible to water hammer.

Selection of tubular batteries, depending on their design

Many apartment owners are interested in the question of which heating radiator to choose, depending on the design. Tubular batteries made of steel (and not only) are a common solution for installation in apartments. The range of such devices is distinguished by a variety of design solutions. Depending on the location of the sectional radiator, you can purchase a wall-mounted or floor-mounted product.

Such devices are installed at different points in the living space. For example, the most common option is to install a tubular battery under the window, however, if desired, the location can be any. They are often used for installation in the center of the room (vertical version). In this case, the height of the battery corresponds to the height of the ceiling.

Helpful information! Some sectional radiators include special wooden panels that are mounted on the top of the device and act as a working surface. Such a shelf can be adapted for a variety of needs, but most often it is used for drying shoes.

Availability of a wide range of shapes, variety color solutions and availability of additional structural elements significantly expand the operational range of such steel products.

Plate heating radiatorsmade of steel (convectors)

The working medium in a plate radiator moves through straight or curved steel pipes. Plates made of the same material are attached to them. The purpose of these elements is to increase the thermal output of the structure.

Plate batteries are resistant to hydraulic shocks. It is also worth saying that the steel rods located inside the structure heat up to fairly high temperatures. However, they are covered by a protective casing, the temperature of which is no more than 40 °C.

Such designs are great for use in rooms with high ceilings. This is due to the fact that heated air moves steadily upward and can rise to a fairly significant height. If necessary, you can independently adjust the temperature regime in which such a heating device will operate.

Plate batteries are able to withstand standard pressure in the central heating system (16 atmospheres). And the maximum pressure for them is 24 atmospheres. It follows from this that convector structures are suitable for use in apartment buildings. Heating battery price of this type on average is 6-9 thousand rubles.

Such heating devices also have some disadvantages. For example, the vertical orientation of the movement of heated air is not only a positive, but also a negative side of a plate product. This is due to the fact that the room is heated unevenly.

The convector plates become contaminated with dust very quickly, which affects the heat transfer coefficient. Cleaning these elements is quite difficult. It is also worth noting that such devices are not aesthetically pleasing and are not suitable for every interior. Such batteries are most suitable for installation in rooms with high ceilings. They are often installed in corridors, swimming pools, etc.

Which radiators are best for an apartment: review of aluminum models

Structures made of aluminum are distinguished by their appearance, as they have a stylish design. However, such products are not the best option for installation in apartments with DSP. This is due to the fact that the aluminum structure has rather thin walls that are not resistant to the destructive effects of corrosion. Given the low quality of the coolant, such a battery may fail after only 5 years of operation.

Helpful information! For apartments that are heated by an autonomous heating system, an aluminum radiator can be a good option. A high thermal conductivity coefficient, as well as a presentable appearance, are the main advantages of such products, thanks to which the demand for them remains good.

Aluminum models are designed for operation in systems with a pressure of 15-20 atmospheres. However, the thin-walled structure used in the DSP cannot boast resistance to water hammer. Considering this fact, it is worth saying that a radiator for a house of this type is best suited for installation in autonomous heating conditions.

Experts advise not to use such batteries if the pressure in the communication exceeds 12 atmospheres. As for the quality of the coolant, aluminum structures function best with a Ph value of 5-6 units, which is rare in domestic DSPs.

Such heating devices are lightweight and therefore easy to store, transport and install. It is important to remember that installing such a battery requires not only care, but also the selection of fittings from a compatible material. Otherwise, corrosion-affected areas will form at the joints. Let's consider materials that absolutely cannot be used when installing an aluminum battery:

• steel;

• brass;
• copper.

The ideal option for installing an aluminum radiator is a heating circuit made of plastic. In this case, the occurrence of corrosion is eliminated, and the heating structure itself is easy to repair or dismantle.

Today you can find a wide selection of aluminum products. They differ in size, color and design. The height of such products ranges from 25 to 50 cm, however, if necessary, you can order a non-standard model (70-80 cm).

Experts note that such batteries have excellent compatibility with temperature control equipment. When installing an aluminum structure, it is recommended to select a thermostat in advance. They also have a glossy surface, so in case of contamination it will not be difficult to clean such a radiator. How to choose an aluminum heating battery, depending on the brand?

If we talk about companies that produce aluminum radiators, the most popular among consumers is ROYAL THERMO. Products from this brand are of good quality and reasonable price. Such radiators are adapted specifically for use in the CIS countries. They are characterized by good corrosion resistance and a long service life (above 10 years).

Aluminum batteries with anode coating - ideal for apartments

Heating devices made of aluminum can be made with a special anti-corrosion coating called anode. To produce such batteries, a high-quality aluminum alloy is used, which is pre-cleaned, and a layer of oxidized anode is applied to the surface.

The technological process for manufacturing such products is quite complex. During it, the structure of aluminum undergoes changes several times, which is a kind of hardening. Thus, the final product is characterized by increased resistance to corrosive influences and can be used in DSP conditions.

Such radiators are manufactured by casting. After which, the resulting sections are assembled into a single structure. One of the main advantages of such products is that, if necessary, you can repair the heating radiator in the apartment. Replacing a section that has been damaged is quite simple due to the design of the heating device.

Helpful information! If necessary, additional sections can be added to the anode battery.

The inner walls of such models are smooth, which promotes heat transfer. The coolant moves through the aluminum structure without any difficulty. The working pressure of anode products is 20-25 atmospheres, which is significantly higher than what is needed under conditions apartment building with DSP.

When purchasing such a heating device, experts advise you to be careful. This is due to the fact that anode products are no different in appearance from conventional cast radiators. Therefore, before buying this or that model of this type, it is recommended that you read the documents for it. Checking the passport and quality certificate allows you to avoid problems when purchasing an anode radiator.

Bimetallic heating radiators: which ones are better for an apartment?

Bimetallic batteries are the most popular in the modern heating equipment market. They have many positive qualities, among which versatility is worth noting. From the name it becomes clear that two metals are used in the production of such heating devices. Combined manufacturing can significantly improve the performance characteristics of these products.

The outer part of the bimetallic structure is usually made of aluminum. This allows you to achieve high thermal output and increase heating efficiency. In turn, the internal channels necessary for coolant circulation are made of high quality steel, which is resistant to corrosion.

It is worth mentioning separately that the outer part, made of aluminum, is additionally equipped with a layer of enamel, which gives such radiators a presentable appearance. Bimetallic batteries have a sectional design. The joining of individual elements is carried out using couplings, which are equipped with sealing rings.

The long service life of bimetallic heating devices is determined by their structure. The aluminum shell does not come into contact with the working environment and acts as a kind of “case” for the internal steel channels through which the coolant moves.

The steel part of the bimetallic radiator is highly resistant to system loads. Such products are capable of functioning at very high pressures (35-40 atmospheres). This makes them ideal for installation in apartments that are heated by DSP.

Also, such radiators are lightweight, which simplifies their installation in an apartment. Of the disadvantages of such products, perhaps only one can be noted - the rather high cost. However, their quality characteristics and shelf life fully justify the price.

If we talk about choosing the best bimetallic heating radiator for an apartment, then you need to pay attention to several popular models. Among them: SIRA RS BIMETAL 500, GLOBAL STYLE PLUS 500, and RIFAR MONOLIT 500. Each of these models has proven itself in operation in an apartment building with a central heating circuit.

Which heating batteries are better for an apartment: pricesand features of copper batteries

Batteries made of this material occupy the smallest segment in the heating market. Their low popularity is due primarily to the fact that they are quite expensive. However, they are distinguished by high technical characteristics and in this they can compete even with bimetallic products.

Such batteries are made from high-quality copper material, which does not have foreign impurities that can reduce the efficiency of the device. Such radiators have a number of positive qualities, although they are rarely used when replacing radiators in an apartment. The main advantage of such products, of course, can be called high efficiency, which is 4-5 times higher than that of cast iron models.

Another advantage of heating devices made of this material is high coefficient inertia. They are able to heat up quickly, which contributes to effective heat transfer. Copper structures are also characterized by high strength characteristics and resistance to hydraulic shocks. They are capable of operating in systems with a pressure of 20-25 atmospheres, which exceeds standard values ​​in a central heating system.

Helpful information! If the coolant is not water, but antifreeze, then the use of copper radiators is the only solution.

It is also worth noting that such heating devices do not need to be painted, as they have high anti-corrosion qualities. The service life of copper products exceeds 10 years. They have a presentable appearance and thanks to this they can decorate any interior, especially those decorated in a classic style.

It is important to remember that for such batteries it is necessary to select fittings from the same material to eliminate the possibility of an oxidation reaction.

Vertical heating radiators for apartmentsfrom different materials

Vertical radiators have several advantages over devices that are mounted in a standard way. They are lightweight, versatile and easy to install. Tall batteries are an excellent solution if there is not enough free wall space for installation conventional device. Vertical models are made from different materials:

Cast iron. Tall heating devices made of this material are quite unpretentious. For them, the quality of the coolant does not matter. They are distinguished by a good heat transfer coefficient, as well as resistance to hydraulic shocks. They are located on average price segment. One of the disadvantages of such tall batteries is their large mass, which makes their installation difficult.

Steel. Experts recommend using panel steel structures in apartments. The wall thickness of such batteries ranges from 1 to 1.5 mm. The outer walls of such products are equipped protective layer enamel, which also gives them aesthetics. Tall radiators made of steel are susceptible to water hammer and are most often used in private homes equipped with an autonomous heating circuit.

Tall heating devices are distinguished by their efficiency and aesthetics. Buy vertical radiator heating for an apartment can be found in any specialized store or you can place an order via the Internet. When purchasing steel devices, it is recommended to pay special attention to whether they have a protective anti-corrosion layer.

Aluminum. High temperature aluminum batteries are low temperature. They provide heating of the room due to their dimensions. The temperature of the working environment in such radiators ranges from 60 to 70 °C. They are able to provide standard temperature conditions in the room (from 20 to 24 ° C). Aluminum vertical heating devices are lightweight and also have the ability to add sections. Such products are most often used in autonomous heating circuits.

Bimetallic. Are different high quality and efficiency due to the use of two metal shells (aluminum and steel). Best suited for use in multi-apartment residential buildings.

Whichbuy a heating batteryfor an apartment: main selection criteria

Before purchasing a heating device for an apartment, you need to pay attention to several key points. There are certain criteria, the study of which will answer the question of how to choose a radiator. Heating batteries must meet all necessary technical specifications, have a passport and instructions.

Let's consider the main factors by which it is necessary to select a battery for an apartment.

Operating pressure. The documentation for the heating device must indicate the operating pressure. Experts recommend purchasing batteries with a certain reserve. The operating pressure of the battery should exceed the same figure in the central heating circuit by approximately 1.5 times. This will allow you to play it safe, since pressure surges often occur in the DSP.

Note! In old-style five-story buildings, the pressure in the heating circuit is about 6-8, and in modern high-rise buildings it is 10-15 atmospheres.

Resistance to hydraulic shocks. This factor has a direct impact on the service life of heating equipment. If a gearbox is not installed in front of the radiator, then water hammer will affect the structure with full force. When choosing a battery, it is recommended to take into account the specific operation of the heating circuit in your home.

Number of sections. If, when choosing a heating device, there are difficulties in determining required quantity sections, then it is recommended to pay attention to models that can be “expanded” if necessary.

Power. This indicator is perhaps the most important. Not all heating devices are capable of maintaining the required temperature in a living room. This is especially problematic in northern regions, where temperatures can drop 40°C below zero. In such situations, experts advise choosing models that can withstand high temperature coolant (up to 130°C).

The temperature in the heating radiator in the apartment must correspond to necessary standards and provide a suitable microclimate in the room. Today it has been established that the norm for a living space is +18 °C. For corner rooms, the walls of which are in direct contact with the street, this figure is increased by 2 °C. Therefore, when choosing a heating device, it is necessary to calculate its power taking into account specific operational features.

Coolant composition. We should also not forget that the battery life is also influenced by the characteristics of the working environment circulating through it. High quality coolant is very rare. As a rule, it includes various harmful (for radiator walls) impurities. Thus, it is necessary to select a structure with thick walls or a protective coating.

Radiator design. This factor is completely individual and depends on the preferences of the apartment owners, as well as the features of the interior.

Easy to install. Such a criterion is not necessary. However, if you decide to install the heating structure yourself, then you should select products that are light in weight. And also study the fastening options and features of connecting a particular model to the heating circuit.

Which heating batteries are better for an apartment?: advice from professionals

So which heating radiators are best to install in an apartment? Experts recommend consulting with a plumber before purchasing a heating device. In any case, you will need to know the features of the DSP and coolant, including:

• heating circuit pressure;
• Ph working environment;
• Coolant temperature.

After receiving all the necessary information regarding the heating circuit, it is recommended to inquire about the surges occurring in the system. This data will help you choose the radiator that suits your parameters.

Helpful information! For residential buildings that have more than 12 floors, excellent option There will be a bimetallic battery installed. Also in this case, cast iron models can be used. If the operating pressure does not exceed 14 atmospheres, and the Ph value is in the range from 5 to 8, then you can use not only cast iron and bimetal, but also aluminum and steel.

If the acidity level exceeds the permissible level (>8.5), then the use of steel and aluminum structures is strictly not recommended. In such an environment, only bimetallic heating structures can function normally. They are also suitable for DSPs where the pressure exceeds 20 atmospheres.

Rating of heating radiators for apartmentsbimetal

Among bimetallic radiators, as mentioned above, three main models can be distinguished. Let's look at their characteristics:

SIRA RS BIMETAL 500. Similar model has several main advantages, which include: high heat transfer coefficient, as well as good sound insulation qualities. Similar products are made in Italy. They are capable of heating a room up to 40 m².

The number of sections of such batteries varies from 4 to 12. Also, the bimetallic radiators of this model are distinguished by high quality painting and aesthetics. One of the disadvantages is increased sensitivity to the work environment.

GLOBAL STYLE PLUS 500. Bimetallic heating device from an Italian manufacturer, characterized by high build quality. The service life of such products is 25 years, as reported by the manufacturer. Another advantage of such a radiator is its resistance to water hammer. A model of this type can withstand pressure up to 35 atmospheres. The maximum coolant temperature for this heating device is 110 °C.

The main disadvantage of such batteries is the enamel coating, which is of uncertain quality. It is also worth saying that the price of a heating battery of this type is higher than that of other representatives.

RIFAR MONOLIT 500. The most popular bimetallic radiator, which is highly resistant to hydraulic shock and has a working pressure of as much as 100 atmospheres. The Rifar company is located in Russia and specializes in the production of heating devices adapted to domestic conditions of use.

A similar model may have a different number of sections. The maximum heat transfer rate of such a battery reaches 2744 Watts, which is quite enough to maintain the necessary microclimate in a room with an area of ​​27 m². The maximum operating temperature that such a battery can withstand is 135 °C. One of the disadvantages of this radiator is poor sound insulation.

Which heating radiators are best for an apartment: pricesand characteristics of aluminum models

In turn, aluminum heating structures have many varieties. Let's consider those that are most popular among buyers:

THERMAL RAP-500. The company producing this model of radiators is located in Russia. Products of this type are designed to work in rather difficult conditions. The maximum operating pressure for the RAP-500 model is 24 atmospheres, which exceeds the standard values ​​in the DSP.

Note! When purchasing an aluminum heating device, you must pay attention to its operating pressure. This indicator is indicated in the relevant documentation supplied with the radiator.

The aluminum battery of this model is resistant to hydraulic surges, therefore it is popular among buyers in Russia. The maximum temperature of the working environment that the RAP-500 radiator from the THERMAL brand can withstand is 130 °C.

RIFAR ALUM 500. Such aluminum batteries, as in the previous case, are produced by a Russian company. They are able to function in severe temperature conditions (up to 135 °C). The maximum area that a model of this type can heat is 25.6 m².

The aluminum model from this manufacturer can withstand pressures of up to 20 atmospheres and is resistant to minor hydraulic shocks in the central heating system. Its service life can reach 25 years under normal use. The main disadvantage of this model is the low-quality protective coating.

ROYAL THERMO REVOLUTION 500. The aluminum radiator from the Italian brand “ROYAL THERMO” is distinguished by the fact that it has the best heat transfer coefficient among similar designs. The maximum power of such a heating device can reach 3982 Watts.

Installation of such an aluminum radiator allows you to provide the necessary temperature conditions for rooms whose area reaches 40 m². This model is suitable for use in DSPs whose operating pressure does not exceed 20 atmospheres. Thus, we can conclude which heating radiator is better for an apartment. The price and photo of such a battery can be easily checked on the Internet.

One of the disadvantages of this heating equipment is that they are quite demanding on the quality of the working environment. The approximate cost of the above devices ranges from 2500 to 5000 rubles. There are also more expensive options, the price of which can reach 12,000 rubles. and even higher. These include vertical aluminum heating devices.

Steel and cast iron radiators: which are better for an apartment?

Steel radiators are affordable, however, they are not very popular in the heating equipment market. Let's look at the models that have proven themselves best in an apartment building with a DSP:

PURMO COMPACT 22 500. Finnish heating equipment has always been famous for its versatility. The steel radiator of this series is no exception. This model has convenient wall mounting, as well as a high maximum power(5572 Watts). The area that this battery can heat reaches 50 m².

Among other things, a steel structure of this type is lightweight and is the most convenient of all for self-installation in an apartment. It can be used in heating circuits with a pressure of no higher than 10 atmospheres, which is a rather noticeable disadvantage.

KERMI FTV (FKV) 22,500. This model allows us to answer the question of which battery is best to install in an apartment with large premises. It is a product of the German company KERMI. The main advantage of this type of steel radiator is that it has a high heat transfer coefficient. The panel design helps to heat the living space. The power of such a device can reach 5790 watts.

Helpful information! The area that this battery can heat is 57.9 m². Therefore, it is ideal for installation in large rooms.

A steel radiator of this type is suitable for use in heating systems with a coolant temperature not higher than 110°C. Among the disadvantages of this model are the low operating pressure (10 atmospheres) and the low quality of the enamel coating.

Cast iron models have many disadvantages, but are still used in apartments. Among the variety of models made from this material, we can highlight one that has many positive reviews, namely: STI NOVA 500.

This radiator is the most popular among consumers. It is a product of an Italian company and has good heat dissipation. This battery is perfect for small rooms(no more than 20 m²). The maximum coolant temperature that a structure of this type can withstand is 150°C. The disadvantages include large mass and considerable coolant consumption.

How to calculate the power of radiators and the number of sections?

The radiator must ensure normal temperature conditions in the room. To do this, it is necessary to calculate the number of sections before purchasing it. Let's look at some rules that will help you perform the corresponding calculation.

First of all, when calculating the power and number of sections of a heating device, you need to focus on its dimensions. It is important to remember that the width of the battery should not be more than 70% of the window opening. To ensure normal heat transfer, the product is installed taking into account the center line of the window. The temperature level of the heating radiator in the apartment affects the heating of the living space, so you should take the location of the device seriously.

The distance from the working surface (wall) to the heating structure should not be lower than 3 and higher than 5 cm. It is also worth considering the distance from the floor to the radiator. It should not exceed 12 cm. In turn, the recommended distance to the windowsill is 5 cm.

Often, for increasing efficiency device, the wall is covered with foil materials. Let's consider what parameters are required to correctly calculate the radiator power:

• room dimensions;
• number of windows and doors;

• the material from which the building is made;
• location of the apartment.

Among other things, it is necessary to take into account individual characteristics heating circuit.

Heating battery pricesfrom different brands

Today the range of heating equipment is wider than ever. But from the many different models, the most popular can be identified, which are distinguished by their adaptability to domestic operational features. An important factor when choosing a heating device is its cost. The price of heating batteries must correspond to their quality.

Bimetallic devices are rightfully considered the most adapted to domestic conditions. Their cost depends on the company, as well as on technical parameters. The price of the most popular bimetallic heating device RIFAR MONOLIT 500 is about 5,500 rubles. Thus, for 5-6 thousand rubles. You can buy a good battery for your apartment.

Note! The average cost of replacing a heating radiator in an apartment is 2000-3500 rubles. The total amount depends on the type of heating device and its installation features.

Aluminum radiators are less expensive. You can purchase a device of this type for only 2500-4500 rubles. In turn, steel and cast iron models are the most expensive. For example, the most popular cast iron battery, STI NOVA 500, costs about 7,500 rubles. The price of the most popular steel appliances ranges from 6-7 thousand rubles.

When choosing a heating device for an apartment, you need to take into account many nuances. But first of all, it is advisable to decide on the financial capabilities and features of the DSP in your home. If necessary, you can seek advice from a specialist who will help you choose an effective device.

Heating radiators - model range for apartments and private country houses from Russian and European manufacturers.

Our assortment includes big choice heating radiators both for apartments (centralized heating in an apartment building) and for a private country house (autonomous heating system). Famous Russian and European brands, there is an exposition with exhibition samples.

Types of heating radiators presented in the Dom-Thermo store:

• Bimetallic heating radiators.
• Aluminum heating radiators.
• Steel tubular design radiators.
• Water heating convectors.
• Antique cast iron retro batteries

Among the classic radiators, special attention is deserved, which not only perform their main role, namely heating the room, they are also able to decorate your interior, becoming a bright element of decor!

Radiators of this type are often quite demanding on the quality of the coolant; they are often not designed to work in a system with high pressure, European brands have become quite expensive today.

As an alternative to expensive designer radiators from Europe, you can consider Russian ones. The collection includes models in vertical and horizontal versions; the front panel of the radiator can be made of painted steel, tempered glass, artificial stone and natural wood.

It is especially worth noting the possibility of applying a drawing or photograph on the front panels of designer radiators. An important point is the possibility of using these devices in centralized heating systems of apartment buildings, because permissible operating pressure pressure 16 atm.

For heating apartments (with a centralized heating system), the most popular option for heating radiators are bimetallic radiators; they usually have an optimal price/quality ratio.

Among radiators of this type, it is better to choose devices with steel collectors, i.e. they completely eliminate contact between aluminum and the coolant, for example, or GLOBAL STYLE. The first option is produced in Russia, on modern European equipment, radiators RIFAR Monolit are entirely welded (without twists between sections), this is big advantage in relation to classic sectional radiators, namely:

• Enormous margin of safety - up to 100 atm.
• There is no “left-hand thread”, on both sides of the radiator there are 3/4" right-hand VR.
• The absence of gaskets between sections undoubtedly adds reliability to heating radiators.
• Possibility to install battery without use

The performance characteristics depend on the material; this should be taken into account when choosing.

Steel heaters

Diverse in design and characteristics. All steel devices have common advantages.

• Good heat dissipation. They quickly heat up and raise the temperature.
• Light weight. The weight is relatively small, which makes installation and transportation easier.
• Long service life provided that the operating rules are followed.
• Strength. They can operate in high-pressure circuits and withstand water hammer.

Of the significant shortcomings, you need to know about instability to corrosion. Poor quality coolant provokes the appearance of rust on the inside, which shortens the service life. Steel is especially sensitive to alkaline solutions.

It is not recommended to drain water in the summer. This activates the corrosion process, which will render the equipment unusable in literally two to three years. When using steel heaters, it is advisable to wash them every three years to remove accumulated waste from the system.

Aluminum batteries

Among the models available to the mass buyer, these are the most attractive in appearance. Their characteristics:

• Light weight, so they are compact and mobile. They are easy to install.
• High heat dissipation. Heats up very quickly and is easy to adjust.
• Relatively low price.

Heating systems are chosen taking into account the main disadvantage - sensitivity to pressure surges. Significant changes aluminum does not withstand and deforms. In addition, only clean coolant can circulate in the system. Even a small amount of abrasive impurities can destroy the protective layer of polymers. This provokes corrosion and failure of the device.

Bimetallic equipment

The most reliable of all existing options. Made from two metals: aluminum and steel (or copper). This must be taken into account when determining which heating to choose. Successfully combines the advantages of both types. Characteristics of bimetal:

• Strength. Withstands increased operating pressure and is not afraid of water hammer.
• Good heat dissipation. Heats up quickly and is responsive to adjustments.
• Long service life, at least thirty years.
• Resistance to elevated coolant temperatures. Can transport liquid 115-130C.
• Low susceptibility to corrosion, especially for models with a copper or stainless steel core.

The main disadvantage is the high price. Their installation in a house, especially a large one, will cost a significant amount.

Cast iron products

• The ability to accumulate heat and slowly release it into the air, so the circulation time of heated water can be limited.
• High resistance to corrosion.
• Complete insensitivity to the composition of the coolant. They work normally even with very low quality liquid.
• Long-term operation, minimum 40 years.

Disadvantages include significant weight, which significantly complicates transportation and installation. Over time, dirt accumulates inside the parts, so periodic cleaning is required. Cast iron is difficult to adjust due to its high inertia. It takes a long time to warm up and cool down.

Design Features

Not only the material, but also the structure determines how efficient the batteries will be.

Sectional radiators

They are assembled from several section elements, which are connected to each other using transition nodes. The heated area depends on their number.

The number of sections is adjustable: if necessary, additional elements are connected or removed. If any of them fails, it can be replaced. The “weak link” of a sectional system is considered to be the areas where elements are connected, where leaks most often occur.

Tubular

They have an unusual appearance, are economical, and give off heat well. They can have a length from 0.3 to 3 m, the number of rows of tubes reaches up to 9. Their shape also varies: standard heaters, radiators, combined with shelves, benches, etc.

The internal volume of liquid is relatively small, which makes it easier to regulate heat transfer.

Panel

Heating plates are placed between two ribbed sheet panels U-shaped. The latter gather in rows, the number of which can reach up to three. The devices use the principle of convection to transfer heat, which makes them quite efficient. They respond well to adjustments. Available in wall and ceiling versions.

Selection criteria depending on the characteristics of the heating radiator

Having become acquainted with the main characteristics of different materials, you can begin to make a choice. In this case, at least three important points must be taken into account.

1. Heat dissipation

The feasibility of its installation depends on how efficiently the heater gives off heat. Let's compare the characteristics. One section gives off this amount of heat depending on the material:

• cast iron - 100-160 W;
• aluminum - 82-212 W;
• bimetal - 150-180 W.

Steel structures, both tubular and panel, deliver 1200-1600 W. It turns out that the most efficient are aluminum devices, followed by bimetallic ones, then steel and cast iron. We must remember about inertia. For leaders it is minimal. This means that they will heat up quickly, but will also cool down quickly after heating stops. Whereas inertial cast iron will heat up for a long time and cool down slowly, heating the room even after the heat is turned off.

2. Durability and reliability

Depends on the material from which it is made. Cast iron is the leader in this matter. It serves for half a century and even more. Of course, this only applies to high quality products made from good raw materials. This is true for both standard sectional devices and designer models.

Second place was shared by bimetallic and steel structures. Their service life is up to 25-30 years. Aluminum ones are designed to last 15-20 years. It should be understood that a lot depends on the correct choice of equipment and actual operating conditions. It would be strange to expect that aluminum installed in a high-rise apartment would last a long time. Strong pressure and aggressive coolant will quickly damage it. Product reliability depends on the manufacturer. It is best to choose a product from well-known companies on the market that have proven themselves well. It is worth studying the technical documentation and certificates. This way you can make sure that the model you like is not counterfeit and has a set of necessary technical characteristics.

3. Connection type

There are four options, suitable for different types of networks.

• Lower. Indispensable in the absence of vertical risers. The inlet and outlet are located below the device. If the pipes are recessed into the floor, the connection is made directly to the wiring.
• Upper. Similar to the lower one with the difference that the connection is made from above. At the same time, there is a risk of insufficient heating of the lower segment, so it occurs quite rarely.
• Lateral. It involves the installation of vertical risers, from which branches are made to the batteries. The liner is located in the upper part, the outlet - in the lower part. Occurs most often.
• Diagonal. It looks like the side, but there is a difference. The coolant is supplied in the upper part of the device, and the outlet is in the opposite lower part. This scheme allows the battery to warm up evenly even at minimum quantity liquids.

An important nuance is the center distance. It must match the supply pipes. This value is measured in millimeters and can vary significantly depending on the model.

The design of heaters varies. Even budget models are attractive. The production technology allows you to paint and, if necessary, apply a design. There are especially many original solutions among tubular steel and vintage cast iron models. The latter come in both wall and floor versions. There are, the upper part of which serves as a bench or shelf.

Selection criteria depending on the type of heating system

The difference between autonomous and centralized is great. Therefore, the heating elements must also be different. Let's start with the differences autonomous circuit.

• Low pressure in the network. The length of the network is small, so significant pressure is not required to move liquid through the pipes. The possibility of water hammer is excluded. The components of the circuit receive a small load, so choose equipment with low protection against pressure drops, including devices with thin walls.
• Low heat loss. The distance to the batteries is small, the liquid does not even have time to cool down a little. This is good because high heating is not required, which means resources are saved. But in an emergency, it is quite possible that overheated coolant will enter the system. Therefore, thermal stability is important for it.
• Possibility of freezing. If the temperature in the rooms drops below zero, the liquid freezes, expands and bursts pipes and heating elements. This is quite rare, but still possible. To prevent it, add alcohol-containing additives to the water or completely replace it with antifreeze or similar compounds. This is only allowed for closed systems, otherwise toxic fumes will appear in the air.

For centralized network other features are characteristic.

Single-pipe scheme

It is almost always used. Involves serial connection of heating units. This scheme has only one advantage - simplicity, and therefore low price. There are much more disadvantages. It is practically impossible to regulate. Because by shutting off the water supply to one link, you stop supplying it to the others. For normal operation, it is necessary to pump as much heated water as possible per unit of time.

To do this, you have to increase the pressure and temperature. Therefore, use in single-pipe scheme Only heaters designed for increased operating pressure and having low hydraulic resistance are allowed.

Two-pipe system

It is devoid of the listed disadvantages.

In it, coolant is supplied through one pipe, and discharged through the second. The heaters are connected to these pipes in parallel; they have to operate at lower pressure. But for apartments, a two-pipe scheme is rarely chosen. Mainly for newly built or extensively renovated buildings.

Regular drainage

In the West, water is not drained. In Russia this happens all the time, especially with the onset of summer - the season for repairs and maintenance of heating pipelines. This is harmful to batteries. The corrosion process on a damp inner surface in contact with air is an order of magnitude faster. Add to this the increased oxygen content in the water content, hardness and abnormal acidic pH. From this it becomes clear that you can only choose equipment with increased corrosion resistance, designed for the widest range of pH values.

Water hammer

Abroad, prudent owners protect the network from water hammer. For example, its startup (turning on the circulation pumps) is carried out through converters that allow the pressure to gradually increase. In Russia, such converters are rarely installed. Usually the switch is turned on, the circulation pump immediately produces its power. The result is a so-called water hammer, which can destroy a radiator not designed for it. This is only one cause of water hammer. They occur for a variety of reasons. This means that when choosing equipment, it is necessary to pay attention not only to the working pressure, but also to the pressure at which the pressure testing takes place. The higher both indicators are, the higher the reliability. For devices installed in high-rise buildings, the operating pressure must be no less than what they will tell you at the local DEZ. Taking these features into account, cast iron and bimetallic devices are purchased for a centralized network, and aluminum and steel for autonomous ones.

Significant criteria They will tell you which one is better to choose. Their prices depend on various factors. These include manufacturer, quality, design, etc. Don't save money thoughtlessly. Products from an unknown company, assembled on the knees, may please you with their price. However, it won't last long. Moreover, an accident with unpleasant consequences can happen at the height of the heating season.

Which heating radiators are best for an apartment? Choosing the ideal battery.

Every person, one way or another, is faced with replacing heating batteries. Failure of old ones, uncomfortable temperature, repairs - the reason is unimportant, the main thing is that replacing the radiator must be approached competently and carefully, because it determines how pleasant it will be for you to be at home. In order for you to call your battery ideal, it is important to determine in advance the required characteristics and figure out which heating radiators are best installed in the apartment.

Stage one. Selecting the type of radiator

Our grandparents did not have much choice: the market offered them only cast iron batteries and a limited range of models. We are luckier, and modern stores are ready to offer hundreds of variations. To understand which heating radiator to choose for an apartment, you need to learn about the disadvantages and advantages of each type.

Sectional radiators made of cast iron

At the words " cast iron radiator“Many people imagine huge and sloppy “monsters” from Stalinist apartments. However, today designers have learned to make models that cannot but be called a work of art: elegant shapes, a huge number of shades, decorative elements - all this makes them attractive. Cast iron batteries are time-tested quality, because they:

• Durable. In many houses they have been standing for more than half a century.
• Reliable. Their designs are not afraid of accidental mechanical damage.
• They are unpretentious to low quality coolant, which makes them ideal for systems with natural circulation.
• They are often cheaper than aluminum, and always bimetallic.
• They have good thermal conductivity and inertia. If disconnected or broken, they will cool down for a long time, retaining heat.

Note! Due to their high inertia, these batteries are not installed in systems with automatic regulation!

Current heating radiators made of cast iron
have an attractive appearance

However, it is cast iron heating appliances that are most often replaced because:

• While resistant to mechanical damage, they are vulnerable to strong water hammer, and therefore are not applicable in unstable systems.
• They weigh a lot. Removing it and repairing it alone is an extremely difficult task.
• They are susceptible to reduced heat transfer. Due to uneven internal walls, impurities characteristic of water in our latitudes accumulate and clog the channels, causing heat transfer to decrease.
• For their stable operation, a large volume of coolant is required, which is uneconomical.

The above allows us to conclude that the choice of cast iron models is optimal for private houses, where water hammer is excluded, and the coolant is cleaner.

Radiators made of steel

There are two types of steel radiators: panel and tubular. Panel is not as popular in our country as, for example, in America, since our plumbing systems are different, and it is the most optimal for private homes.

For panel radiators preferred terms of use -
for a private home rather than other housing.

However, panel steel heating radiators have a place because they are characterized by:

• Wide overall and design model range, which allows you to select a battery even for non-standard size niches and openings.
• Optimal heat transfer performance.
• Low coolant consumption, which is economical.
• Rust resistant.
• The ability to update the appearance of the battery using paint.

The advantages of steel batteries stem from their design. These devices are made from 2 steel sheets, between which there are channels for water movement. High-carbon steel itself is slightly susceptible to corrosion; to increase this parameter, the radiators are coated inside and outside with powder enamel.

Construction of a steel model with explanations:

The disadvantages of steel radiators include:

• Vulnerability to water hammer. Thus, with a water hammer exceeding 12 atmospheres, there is a high probability of section rupture.
• Vulnerability to low quality coolant, which is explained by the lack of internal protection. If the hard coolant damages the coating, then rust will gradually begin to form in this place, which will damage the radiator.
• The service life of such a battery ranges from 15 years.
• The need to install shut-off valves.

Tubular heating devices have better characteristics than panel ones. Thus, they can withstand pressure up to 15 atmospheres, have a more aesthetic design, are better protected from corrosion, but are also more expensive.

If you decide that you want a heating device made of steel, but cannot choose its type, then prefer a tubular one. Such batteries are more reliable and durable.

Heating devices made of aluminum

When considering which heating radiator is best to choose for an apartment, many choose aluminum models. When they talk about the advantages, they mention that they can be assembled and disassembled independently, taking into account the area and features of the room. However, they are silent that it is difficult to do this, and is rarely necessary (except for the repair of a specific section), and the use of aluminum batteries has more objective advantages:

• Low inertia, which is why radiators quickly warm up the room to a comfortable temperature.
• Wide range of models and light weight.
• High power, which allows you to achieve warm temperature even on cold winter nights.
• Aesthetic and versatile design.
• Working pressure up to 20 atmospheres, which is sufficient for centralized systems (reduces the risk of damage due to water hammer).
• Average price, which varies depending on the number of sections.

Aluminum radiator Global

It would seem that you can go and buy an aluminum radiator right now, but this device also has its drawbacks:

• When the system is turned off, the battery quickly cools down and cannot maintain a comfortable temperature.
• Vulnerability to corrosion.
• Demanding on water pH, since hard impurities damage the walls.
• Vulnerable to mechanical damage because aluminum is a flexible metal.

Advice:
To be sure that the aluminum model will last as long as possible, choose models with a polymer coating.

Bimetallic heating devices

Bimetallic batteries without embellishment are the best heating radiators for an apartment. Their peculiarity is in combining the advantages of two metals, namely steel and aluminum. The steel channels through which the coolant moves are resistant to corrosion and transfer heat to aluminum panels, which are characterized by high heat transfer. Thanks to this design, bimetallic batteries:

• Are different high strength, withstand even strong water hammer, which, although rare, are found in centralized heating systems.
• They can be used with any quality of coolant and do not lose heat transfer or safety margin at low water pH.
• Characterized by long-term operation. You can use this battery for more than 20 years.
• Maintain a comfortable temperature regime with a small volume of coolant.

Heating devices made of bimetal have a higher cost,
however, more suitable for an apartment

The disadvantages of bimetallic batteries include:

• High cost relative to other types.
• Low probability of collector clogging. The tubes in the radiators are narrow, which can cause blockages, which can be easily solved by cleaning.
• Vulnerability to high oxygen concentrations in water. Under such conditions, the steel oxidizes, which can lead to corrosion, but no device is protected from this.

The high cost of bimetallic batteries is fully justified by their excellent performance data and is compensated by their long service life.

How to choose a heating radiator for an apartment

In order not to regret choosing a battery, it is important to carefully consider not only the types offered, but also the factors that will influence their performance. These include:

• Functional pressure. In the characteristics you will find items with working and test, but what is important for you is the functional one, since it should be higher than the rest. This is explained by the fact that without measurements you cannot know exactly what the average pressure in your heating system will be: for old Khrushchev houses this parameter varies within 6-8 atmospheres, and for new houses - 10-12.
• Resistant to water hammer. No matter how manufacturers and articles on the Internet scare you, strong water hammer is not such a common problem; it largely depends on the work of utility services. However, if from an old radiator during preparation for heating season If you heard clicks or a hum, then it is better to choose a new one with a high safety margin.
• Resistant to poor water quality. In our country, the coolant is not of high quality, regardless of whether it is new or an old house. For apartment buildings, it is optimal to use battery models with thick walls and a protective layer, which will allow them to withstand constant friction due to hard particles.
• Heat transfer indicator. It is this parameter that determines how warm your room will be.
• Aesthetics. Design is a matter of taste, but you shouldn’t limit yourself and take an “ugly” model just because it has good characteristics: will always find the optimal analogue.
• Duration of operation. You will not be able to determine this parameter in advance, so it is better to focus on the one indicated in the passport.

These are the main parameters that you should pay special attention to when choosing a battery model.

Stage three. Let's talk about power and sections

Before choosing a device, it is important to calculate how many sections you will need at a certain power. This is necessary to minimize the cost of paying bills, while making every room warm.

Before you begin the calculations, you should take into account the parameters stated in SNiP:

• The device should not be wider than 70% of the window.
• It is better to install the heater centrally from the window line
• Maintain a distance of at least 3 cm between the wall and the battery.
• The battery should be higher flooring, however, no more than 12 cm.
• You should leave a distance of 5 cm from the window sill to the battery.

Compliance with these requirements makes calculations more accurate and objective.

Calculating power

The required power indicators are affected by:

• Your house is panel or brick.
• How much area does your room occupy?
• How many windows are there, and what type are they (frames made of wood or plastic).
• Are there external walls?

It is difficult to determine how each indicator will influence; it is easier to focus on standardized examples. So, for rooms where the ceilings are 3 meters high, there is 1 wooden window opening and door, it is recommended to take a battery with a power of 90 W to 120 per 1 sq. meter.

Note! If you want to make calculations more accurate, then use simple formulas:

• To start, multiply the area of ​​the room by 100 watts.
• If it has one window and 2 external walls, increase the result by 20%.
• If there are 2 windows and 2 external walls, increase the result by 30%.
• If the window is in the north or northeast, add 10%.
• If you want to place the battery in a recess, add 5%.
• If you plan to cover the device with a solid screen, add 15%.

Calculating the number of sections

To calculate how many sections are needed to maintain a comfortable temperature, we need to know the average power of each. To know exact value can be found in the heater’s passport, but the average parameters will be as follows (in watts):

• Radiator made of cast iron - 80-150.
• Steel radiator - 450-5700 (the last figure for panel ones, since they do not have sections).
• Aluminum radiator - 190.
• Bimetallic heating devices - 160.

This calculation is approximate and suitable for those who do not want to spend a lot of time on a tedious selection. More accurate calculations are produced with an emphasis on heat transfer, focused on the volume of air in cubic meters that the radiator will need to heat. Each room is calculated separately; the main indicator is the power of the selected device.

To make it clearer, let's look at a simple example. For this, let’s take the fact that heating 1 cubic meter of air to a comfortable temperature requires approximately 40 W of power. There is also a room whose area is 10 square meters. meters, and the ceiling height is 3 meters.

First you need to calculate the volume. To do this, multiply 3 by 10, we get 30 cubic meters. Now we calculate the approximate power parameter: multiply 40 by 30, we get 1200 W. Let’s take 200 watts as the average power parameter for an individual section. Finding out the required number is simple: divide 1200 by 200, we get 6. So we found out that for the area we have chosen, we need a heating device with 6 sections.

Note! If you get an uneven value, for example, 7.1 or 6.3, then you only need to round the result up!

• Formula for calculating cubic capacity: 3 x 10 = 30 m3.
• Determination of energy consumption: 41 x 30 = 1230 W

Important information! If you want to install a corner radiator at home, you must also take into account the heat loss coefficient, which is determined by the climate in your area and varies between 1.1-1.3 units. To calculate, you must first multiply the resulting parameter of the required power (in our case 1200) by a coefficient, for example, by 1.1, and only then divide by 200. You get 6.6 sections, round up to 7.

The ratio of the number of required sections to the battery power and room area:

Power of 1 section heating radiator according to passport, W	Room area in square meters
	10	12	14	16	18	20	22	24
140	8	9	10	12	13	15	16	17
150	7	8	10	11	12	14	15	16
160	7	8	9	10	12	13	14	15
180	6	7	8	9	10	12	13	14
190	6	7	8	9	10	11	12	13
200	5	6	7	8	9	10	11	12

Calculation of the number of required sections using the example of a real model:

Working pressure is a parameter that should not be forgotten

Many people forget about this parameter, although it is very important. When checking the passport of the heating device, check whether its operating pressure will be higher than what is observed in your system. If it is lower, then during preparation for the heating season there is a high probability of damage to the device. A list of average ratings for each battery type will help make your choice easier (in atmospheres):

• Cast iron radiator - within 11.
• Steel radiator - within 10.
• Aluminum radiator - within 19.
• Bimetallic batteries - up to 35.

Advice:
You shouldn't overpay just because of a large safety margin. The fact is that the shut-off valves can withstand a pressure of a maximum of 15 kg/cm3, and this figure cannot be increased.

Differences between central and autonomous heating systems

To understand how to choose heating radiators, which ones are best for an apartment, and what to focus on, it is also good to take into account the features of your heating system. Today there are 2 of them: centralized and autonomous, the first is used in apartment buildings.

Modern radiator in the interior

A centralized heating system is characterized by the fact that external heat sources, for example, a boiler room, are used to heat the room. Its advantages include:

• Low cost fuels, such as coal, gas and others.
• Environmentally friendly due to the absence of harmful combustion products.

The system has more disadvantages, for example:

• Poor water quality, which causes pipes and devices to rust and fail faster.
• The presence of grains of sand and solid elements in the water that can scratch the radiator.
• Unstable water temperature.
• High pressure.
• The likelihood of water hammer when a pressure surge occurs.

An autonomous heating system has many more advantages over a centralized one:

• You can regulate the heating yourself.
• The house is provided with hot water all year round.
• By adjusting the temperature you save on bills.
• Better water quality compared to a centralized system.

A significant disadvantage of an autonomous heating system is the need to obtain permission to organize it within the apartment. Also, an autonomous system is more difficult to install, and its repair is more expensive, but it pays off such costs by being economical in terms of paying bills.

Central heating system: operating features

The choice of radiators is determined by various factors. But the most important thing is the type of heating system at home. Most multi-storey buildings are served by central heating networks. They differ in their advantages and disadvantages. If your house is connected to a central heating network, equipment for it should be selected taking into account the technical characteristics.

• The operating principle of the central heating system is as follows. Heat is generated using a special unit, after which it is supplied through highways to each apartment and returned. The coolant circulates continuously thanks to powerful pumps. In each case, a different set of heating equipment can be used. But most often the pumps operate at a load of 16 atmospheres. Heating radiators installed in the apartment must withstand such a load. Therefore, pay attention to this technical indicator when choosing batteries, in the equipment passport, the manufacturer must indicate the maximum permissible pressure level at which the radiator will function uninterruptedly and safely.
• The coolant circulating through the main lines of the central system is supplied with uneven pressure. This provokes water hammer in the system, which negatively affects not only the efficiency of heat transfer, but also the operating life of the heating batteries.
• The coolant temperature is also not constant. One day the batteries are cold, the next they are too hot. Naturally, sudden changes temperature conditions negatively affect the condition of pipelines and heating radiators.
• Sooner or later, the central heating system fails. Accidents, leaks, and technical drains occur. The battery installed in the apartment must withstand such difficult operating conditions.
• The quality of the coolant also leaves much to be desired. Most heating radiators on the market meet European requirements, which set other standards for the quality of water circulating through the mains. In our country, central heating systems often use contaminated, rusty water with a high lime content. The raw materials from which heating batteries are made are often not at all intended for use with low-quality coolant. Contained in water chemical elements contribute to rapid wear of the inner shell of radiators, which leads to a reduction in the service life of the equipment.
• The characteristics of the connection of materials play an important role in matters of equipment durability. You can purchase the most expensive and durable heating batteries, but if you connect them with pipes that are incompatible with this type of equipment, there can be no talk of a long service life. In addition, this will negatively affect heating efficiency.

The conclusion is simple: not every heating radiator can be used in a central heating system. Many of them are not designed for the quality of coolants that are used in modern systems. You should start choosing batteries only after you have determined the conditions under which they will be used.

Bottom line - how to choose a heating radiator for an apartment?

If we talk about manufacturers, it is better to pay attention to those who have proven themselves in the market: Sira, Global, Rifar and others.

What to look for when choosing a good radiator for an apartment

The choice of heating radiators for an apartment is influenced not only by specifications and features of the functioning of the central system. There are other determining factors.

• Operating pressure. The technical data sheet of the equipment must indicate the operating pressure. Its indicators must exceed those of the central heating system by at least 1.5 times. This indicator is really important, since it is the operating conditions of the equipment in domestic heating systems, as well as differences in operating and test pressure, that cause premature failure of the equipment. In old five-story buildings, the working pressure, as a rule, is at least 6-8 atmospheres. In new-plan houses this figure is higher and ranges from 12-15 atmospheres.
• Resistance to hydraulic shocks. The factor also needs to be taken into account, since it has a direct impact on the service life of radiators and their performance properties. It is impossible to prevent the occurrence of water hammer in modern central heating systems. All that remains is to take into account the performance of utilities and choose batteries that are more resistant to water hammer.
• Number of sections. If it is difficult to decide on the quantity, you should choose radiators that can be expanded in the future, that is, adding new sections. This will increase the heating capacity of the equipment.
• Heating battery power. The practicality of radiators determines their heating properties. When it’s frosty outside and -40 degrees Celsius, not every type of equipment can cope with the increased load. Therefore, when choosing, always pay attention to the maximum coolant temperature. Many radiator models, especially those made by foreign manufacturers, are designed for a maximum coolant temperature of 80-90 degrees Celsius. But when it comes to choosing batteries for houses located in harsh climatic conditions, it is better to give preference to radiators, where the maximum operating temperature of the coolant will reach 120-130 degrees.
• Coolant composition. Since most central heating systems use coolant, chemical composition which is far from ideal, this leads to rapid wear of the internal coating and walls of the radiators. Therefore, it is better to choose thick-walled products. Radiators appearance. It is important that the design of the heating radiators is in harmony with the interior of the apartment. The range of offers on the market will allow you to make the best choice.
• Life time. This indicator depends on the operating conditions of the radiators and the technical features of the central system. Give preference to those products whose declared service life is at least 20-25 years.
• Ease and convenience of installation. This often depends on the design features of the radiators, as well as the weight of the product. You are unlikely to be able to install a heavy cast-iron battery yourself, but you can probably handle a lightweight panel design alone.

The long-term operation of the entire system and its efficiency completely depend on the correct selection of batteries. Increased demands are placed on such equipment, especially when used in an apartment. IN apartment buildings Heating is most often tied to a centralized circuit, which increases the risk of water hammer. An analysis of individual models and equipment characteristics will tell you which ones are best for an apartment.

Heating radiators: which ones are better for an apartment and choice of type

When deciding which heating radiators are best to install in an apartment, you need to learn more about the capabilities of the heating system in multi-apartment buildings. In this case, there is no need to set up and monitor the operation of the equipment, controlling the entire process. moves from one device to another, giving off heat through the surface of the radiator.

Such a system has various problems. The water in the batteries often changes temperature, and there are also pressure changes. Particularly dangerous is a water hammer with a battery breakthrough.

When selecting heating devices, you should pay attention to the following criteria:

• material of manufacture;
• the ability of the structure to withstand pressure of about 12-15 atmospheres;
• the material must be safe and resistant to sudden pressure and pressure changes;
• the product should not be subject to corrosion or any damage;
• an important indicator of the product is the heat transfer of the equipment;
• service life;
• appearance of the product.

When choosing radiators, it is worth considering the operating and test pressure.

Helpful advice! It is not worth paying more money for the safety margin of pressure indicators, since shut-off valves will not withstand a pressure of more than 15 kg/cm².

Types of heating batteries in an apartment and their characteristics

Before choosing heating radiators for your apartment, let's look at the main manufacturing materials:

Types of radiators	Characteristics
Cast iron	Pressure value from 10 to 13 bar. The section power indicator is up to 160 Watt. Acceptable temperature indicator is 150 degrees.
Aluminum	Pressure from 7 to 17 bar. The maximum water temperature in the battery is 110.
Steel	Pressure from 6 to 15 bar. High heat transfer rate. Corrosion protection.
Bimetallic	Pressure up to 50 atmospheres and temperature up to 130 degrees are provided.

Features of cast iron radiators

Cast iron radiators were especially popular back in Soviet times. Such designs have certain advantages:

• long service life;
• corrosion resistance;
• affordable price;
• maintaining temperature when the system is turned off.

Also, such designs are resistant to various types coolants, ease of installation and resistance to various chemical compounds.

The disadvantages include the fact that such products long time heat up, are characterized by heavy weight and do not have protection against water hammer. The choice of cast iron types of heating radiators for an apartment is just as good as the choice of this option for industrial buildings, country houses and cottages.

Steel models

Steel products do not have sections, but are made as a set. Can withstand temperatures up to 120 degrees. It is believed that it is better to install them in buildings with autonomous or small buildings. Can not use similar elements in rooms with high temperatures: in bathrooms or. The steel unit must always be filled with water, which protects it from.

By deciding which heating radiators are best for an apartment and choosing this option, you can get certain advantages. This device warms up quickly, is characterized by increased heat transfer and has a presentable design.

Steel options come in tubular and panel versions. The latter have the following advantages:

• excellent heat dissipation;
• environmental safety;
• low cost;
• high level of efficiency.

The disadvantages include susceptibility to corrosion, the inability to use in multi-story buildings, and convection can cause drafts.

Tubular models have the following advantages:

• increased heat transfer rate;
• operating pressure from 8 to 15 bar;
• protective properties against corrosion.

The main indicators of these two types of radiators differ little. Only tubular models are more expensive due to higher values.

Aluminum products

Many people are interested in how to choose a heating battery or radiator made of aluminum. There are two types of such instructions. Cast - produced by casting and have wide walls. Extrusion – characterized by the technology of extruding aluminum alloy through an extruder. Sections cannot be added to such a product.

The advantages include:

The disadvantages include susceptibility to corrosion, fragility and a tendency to leak. In addition, such structures do not provide protection against water hammer. Similar designs are produced by representatives of different countries. These are the Chinese companies Konner and Lammin. Russian company Rifar and equipment from Italy from Global and Royal Thermo companies.

Note! It is important that the device has a polymer coating, which allows you to extend the service life of the product.

Which radiator is better, aluminum or bimetallic?

When deciding which heating radiator is better for an apartment - bimetallic or aluminum, it is worth knowing their features.

A special feature of the aluminum product is that it can only be purchased for private homes. Such equipment cannot be installed in production areas where pressure surges occur. An aluminum radiator can be used in conjunction with a temperature controller. Exceeding the permissible pressure may result in battery rupture and internal corrosion.

They can last for a long period of time, as they are resistant to pressure pressure up to 50 atmospheres. These structures consist of a steel core and aluminum ribs. They warm up quickly and are characterized by an aesthetic appearance. The disadvantages include the accumulation of slag deposits inside the sections. In addition, due to the use of several material options, the heat transfer rate may decrease.

• German manufacturer Arbonia sells high-quality devices that differ modern design and strength.

How to calculate the power of radiators and the number of sections?

The purchase of effective, high-quality equipment should be complemented by correct calculations of the number of sections.

SNiP consists of design rules and operating standards for heating systems. Radiators need to be installed taking this into account. For the calculations to be effective, the following rules should be used:

• the maximum width of the structure should not exceed 70% of the size of the window opening;
• the product must be mounted along the center line of the window;
• the distance between the wall and the device is 3-5 cm;
• the product should rise above the floor no more than 12 cm;
• the distance from the battery to the window sill is 5 cm.

In some cases, for better heat transfer, the wall surface is covered with a special one. Such rules promote the free movement of air masses. For correct calculation you need to know the following parameters:

• room sizes;
• number of windows;
• materials for building a house;
• placement of rooms relative to cardinal directions;
• technical parameters of the heating design.

The table shows a simple calculation of the number of sections.
