Volume of a cast iron battery fin. Important technical characteristics and weight of cast iron radiators

A radiator is an integral part of any apartment. This equipment provides heating to the house during the cold season. However, not every apartment can install one or another battery. After all, the requirements for this device directly depend on the area of ​​the room in which it is located. First of all, this concerns power. The quality of heating of your home depends on this indicator. Therefore, today we will teach you how to correctly calculate battery power.

We calculate the power of the heating radiator

Heating radiators provide heating to the apartment. Without this device it is impossible to imagine any modern home. It is thanks to him that we can spend cold winter evenings in comfort.

Heating radiator power plays great importance in heating the house. This is the device that gives most heat to the room. Without it, you would live in a cold and damp environment.

Heating radiators can be made from different materials. It can be aluminum, cast iron or steel. Also, such devices differ in their structure. They can be made from individual sections or as a panel.

When calculating power, the material from which the radiator is made special significance does not have. But the structure of such a device plays an important role in the calculation.

The radiator, consisting of sections, can be assembled independently to the required length. Thus, in this option you will calculate the number of sections at which the radiator will have the required power.

How to make a calculation required quantity radiator sections:

1. The first thing you need to find out is the area of ​​the room. To do this, you need to multiply the height of the room by the length of its two adjacent walls separately, and then add the two resulting numbers.
2. You also need to find out the power of a single radiator section.
3. Next, the area of ​​the room is multiplied by the power of a single radiator section and divided by 100.

As a result, you will get a number that will be equal to the required number of radiator sections. It needs to be rounded up.

If you want to purchase panel radiator. The calculation will be different. In this case, you will calculate the power of the device.

1. First you need to calculate the volume of the room. To do this, you need to multiply the height of the room with the number obtained by multiplying the lengths of two adjacent walls.
2. The resulting number is multiplied by 41. This figure is the required power to heat one cubic meter.

The resulting figure will be equal to the power of the radiator. It needs to be rounded up. In this case, you can divide the value between two radiators.

What is the power of one section of a cast iron radiator?

Cast iron radiators are the very first batteries. However, despite the new models, such devices still occupy first place in popularity.

Cast iron radiators MS-140-500 do not differ in their original design. However, such accordions are reliable and have high efficiency.

On this moment The appearance of the cast iron radiator has reached a new level. You can see the models yourself different color. Moreover, some batteries of this type have a beautiful relief and even cast iron.

Heat transfer cast iron radiators high. The power of a single section of such a device is 160 watts. However, it is believed that on average this figure can decrease to 140 watts. There is a comparison table different types radiators. And in it the cast iron battery takes first place. Let's look at the advantages of such devices.

Advantages of cast iron radiators:

1. Cast iron has a very high heat capacity. Thanks to this, radiators made of such material are preserved for a long time and large quantities give off heat.
2. Cast iron batteries, provided they are welded correctly, can easily withstand water hammer and temperature changes.
3. The walls of such batteries are not susceptible to corrosion and wear. Therefore, absolutely any coolant is suitable for them.

If you choose this radiator, then you can be sure that you will not have any problems during its operation. However, many people are not satisfied with the appearance of such devices.

Average power of aluminum radiator section

Aluminum radiators are the most popular. This is due to their modern appearance and ease of maintenance. You can purchase such models at a very affordable price in specialized stores.

In addition to aluminum and cast iron radiators, there are steel batteries. The dimensions and weight of such devices are significantly inferior to models made from other materials. This is the advantage steel radiators.

Aluminum radiators can withstand up to 15 atmospheres. Also they are not afraid high temperatures. That is why our population loved them so much. The design of aluminum batteries is quite laconic. Of course, such designs are not particularly original, but they can fit into any interior. The question of the power of a single section of such batteries is still an issue. It is impossible to answer this accurately, since different models can have from 180 to 200 watts. The aluminum battery sections are very easy to connect. Typically, such services are provided by store salespeople, but if necessary, you can assemble it yourself.

With all the advantages of aluminum radiators, they also have some disadvantages. In order not to regret what you did later, you need to familiarize yourself not only with the reviews “for”, but also with the positions “against”.

Disadvantages of aluminum convectors:

1. Aluminum is the material that is most susceptible to corrosion. Moreover, during the rusting process, it can release gases. Therefore, such devices are most applicable in individual heating systems, where the water quality is higher.
2. If the sections are connected incorrectly, aluminum radiators may leak. And in this case it will be impossible to repair them.

Aluminum radiators are very popular due to their high efficiency and low weight. However, they have serious disadvantages that must be taken into account.

The volume of water in one section of a cast iron battery

Many people are interested in the volume of water in one section. Since some people claim that big sizes Such radiators indicate that one section contains more than three liters.

In fact, most of the volume of such a device is occupied by cast iron itself. He has thick layer, and that’s why the product seems so big. Let's see how much water there can be in one section of a cast iron battery.

How much domestic water will go into one section cast iron battery:

• The radiator of the MC 140/500 model holds 1.45 liters of water per section;
• The battery of the MC 140/400 model can hold 1.28 liters of water in one section;
• For designs of the MC 140/300 model, 1.11 liters of water are needed.

As you can see, cast iron batteries do not hold as much water as it might seem. Therefore, you don’t have to worry about the efficiency of this resource.

Calculating the power of a heating radiator (video)

The power of the radiator should play a major role in its selection. Therefore, do not forget to calculate this parameter in time so as not to get into embarrassment.

Sectional cast iron radiators began to be produced more than a hundred years ago. They were first used in systems steam heating, and then in central systems ah water heating. Classic Soviet-made cast iron radiators MS-140 are installed in many old Russian houses.

The advantage of cast iron radiators is their high reliability and long service life (more than fifty years). The radiator consists of sections made of high-quality cast iron, which are connected by nipples made of malleable cast iron. Large diameter The flow section makes cast iron radiators unpretentious to the quality of the coolant and allows the use of contaminated water, typical for central heating systems in Russia; for the same reason they have low hydraulic resistance. Thick walls and Chemical properties cast iron gives radiators resistance to corrosion, which is important in summer period when the water from the heating system is drained and the radiator is left to rust “dry”. Cast iron radiators are the cheapest of their counterparts, with the exception of highly artistic products with complex casting. Their prices are much higher.

Disadvantages of cast iron radiators in their large mass. For this reason, installation becomes more complicated and transportation costs increase. Radiators made of cast iron have high thermal inertia (they take a long time to heat up and take a long time to cool down) , therefore they cannot be used in heating systems with automatic adjustment temperature, due to the long response time.

Reliable and time-tested heating devices. The design of MS 140 is ideal for Russian heating networks. They are completely insensitive to the quality of water used as a coolant. The most affordable heating radiators.

Dimensions of cast iron radiator

Cast iron radiators, having celebrated their centennial anniversary, continue to bring heat to residential buildings and are in no hurry to give way to aluminum analogues and compact convectors. Cast iron has many undeniable advantages: corrosion resistance, thermal efficiency, durability. Modern devices are different attractive design, and the line of retro-style models looks simply luxurious. Despite all their advantages, they have one drawback - the weight of a cast iron radiator is several tens of kilograms.

How much does a cast iron battery weigh?

Knowing and taking into account the weight of the heating battery is especially important in cases where the devices are installed on thin walls and partitions made of fragile materials. If the load is higher than normal, you will have to abandon the wall mounting and fix the radiator to the floor.

The weight of the cast iron radiator section without coolant is from 7.1 to 7.5 kilograms - exact values depend on the height of the product and other features of the model. Among the new developments there are lightweight modifications with a section weight of 5.7 kg. Standard batteries consist of 4–10 sectional elements, but there are also “giants” that include 20 or more sections.

Knowing how much a section of a cast iron radiator weighs, it is easy to calculate the mass of a battery consisting of several tanks. For example, a device with 7 sections will weigh 48–52.5 kg, and a ten-section device will have a load of 70–75 kg. In order to facilitate installation, several devices of 5–7 sections are chosen, rather than bulky multi-section structures. If necessary, prefabricated devices are modernized by adding or reducing the number of elements.

When calculating the total mass of the heater, it should be taken into account that the volume of the cast iron radiator section is on average about one and a half liters of liquid. In new economical models, there are figures from 1 liter, and in old-style radiators, the amount of coolant can reach 1.7 liters. Naturally, the weight of the device will increase after starting the heating system.

Technical characteristics of cast iron batteries

Others are no less important specifications cast iron radiators. Their knowledge and ability to calculate the necessary parameters help to correctly determine the number of sections in the heat source.

Comparison of the characteristics of cast iron batteries and other types of devices

Power is the main indicator of efficiency

Knowing the power of a cast iron heating radiator, it is easy to calculate the number of devices. It is important to consider that in systems with central heating, where it is impossible to control the temperature of the coolant, an excess of heat sources is no less unpleasant than a deficiency. The consequence of the error is increased dryness of the air, bad smell burnt dust, drafts due to the need for frequent ventilation.

The thermal rated power of one section of a cast iron radiator of the standard modification is 160 W. When calculating the dimensions of a heating unit, it is necessary to determine the amount of heat flow in the home. This indicator depends on wall material used for construction, and the degree of thermal insulation of the building. IN panel house the heat flow value is 0.041 kW/m3, in a brick building - 0.034 kW/m3, and if there is high-quality thermal insulation– 0.02 kW/m3, regardless of what the walls are built from.

To calculate the number of links, a simple formula is used: the figure indicating the volume of the room is multiplied by the heat flow of the room, after which the resulting value is divided by the nominal heat flow of one section (0.160 kW). The total is rounded to a whole number - this is the number of required elements. It is not necessary to combine them in one radiator - if there are several windows, it is better to install the device under each opening.

The heat transfer of cast iron radiators directly depends on the number of sections in the heater and their size. The dimensions of the battery are selected taking into account the area of ​​the room and the dimensions of the window opening. In order for the power declared by the manufacturer to “work”, the length of the battery must cover the window by at least 70-75%, and the distance to the window sill must be from 8-12 cm.

Dimensions of cast iron radiator

Manufacturers adhere to generally accepted sizes of cast iron heating radiators - this is a tribute to tradition and an important factor ensuring effective work and equipment safety.

1. The width of one section of the cast iron “accordion” varies from 35 to 60 cm. Different meanings found not only among competing manufacturers, but also in various model ranges one manufacturer.
2. The depth of standard products is: 92, 99 and 110 mm. In design modifications, other numbers are possible.
3. The center distance in standard versions is 35 and 50 cm, but other parameters are also found.
4. The height of the devices is always greater center distance and can be increased by the length of the legs if we are talking about a floor model.
5. The area of ​​a cast iron radiator section is on average 0.25 square meters. meters.

Service life and other parameters

The service life of cast iron heating radiators is calculated in decades. Once installation is complete, you won’t have to think about replacing batteries for the next 20-25 years. It is known that in pre-revolutionary houses, equipment cast more than 100 years ago still works properly.

The operating pressure of cast iron devices is 9 atmospheres, which allows their use in autonomous and central heating. Also, cast iron is not afraid of coolant drains during the summer season - it calmly waits for the heating period without losing its properties.

Having studied the technical characteristics and learned how much a cast iron heating radiator weighs, practical people entrust system calculations and installation to specialists. This is always safer than trying to do an unfamiliar task with your own hands.

It’s unlikely that you dream of spending this winter in an icy apartment under ten blankets. Therefore, today we will talk about heating radiators, namely about the cast iron radiator MS-140.

We will review the characteristics, tell you how to choose the right number of sections and how to install it all. But first things first.

Why cast iron?

Cast iron radiators have a number of advantages, let’s look at the main ones:

• High resistance to corrosion. This property is due to the fact that during operation the surface of the radiator is covered with “dry rust”, which prevents corrosion from developing. Cast iron is also very wear-resistant; stones and various debris from heating pipes do not cause much harm to it;
• Good thermal inertia. The cast iron heating radiator MC 140 retains 30% of the radiated heat even an hour after the boiler is turned off, while for steel radiators this figure is only 15%;
• Long service life. So for high-quality cast iron radiators it can reach 100 years, although manufacturers talk about 10-30 years of reliable operation;
• Big internal section radiators. It is for this reason that cast iron heating radiators MC 140 500 rarely require cleaning;
• Cast iron, due to its composition, under no circumstances can cause electrochemical corrosion. In other words, no conflicts can arise with plastic (steel) pipes.

Let's talk about the characteristics

Now is the time to present to your attention the technical characteristics of cast iron radiators.

But, knowing the advantages of devices and their characteristics, do not rush to run to the store. After all, before this you need to find out how many sections are needed for the heating to be truly effective.

Section counting

The number of sections directly depends on the configuration of the room. Of course, the main parameter here is area, but there are others important factors, such as: zoning, floor, ceiling height, niche dimensions, presence of double-glazed windows, number of windows.

Advice. For corner rooms, it is better to choose more powerful radiators and make several additional sections (1-2). This is explained by additional heat losses, which can affect the comfort of residents.

Let's consider the formula for calculating the required number of sections for a room with a ceiling height of no more than 3 meters and an area of ​​50 square meters:

Advice. If as a result of the calculation you received a fractional number, then it is better to round it up - provide a small power reserve.

Now that you know how many sections are needed, you can proceed directly to the installation.

Installation

The number of sections has been calculated, the radiators have been purchased, all that remains is installation. There are two options here - turn to specialists and spend money, or do everything yourself. Let's consider the second option.

Selecting fastenings

The first installation step is choosing a mount for the radiator. In the photo you can see Various types fastenings.

For example, for sectional radiators Pin and corner brackets are used. The first ones are used to fix the battery on a wall made of brick or plaster, and the corner ones are used if the wall is wooden. It should also be remembered that for corner mount You need to stock up on screws and dowels.

Types of fasteners. As you may have guessed, fastenings No. 3 and No. 4 are applicable for our case.

Direct installation

At this stage you need to select places to install the brackets. Remember that one radiator requires at least three brackets. Afterwards, using dowels and a drill, you need to secure the brackets.

The next step is to attach the radiator to the brackets.

Advice. No need to rip it off right away protective film from the radiator, first install it on the brackets, and then, without fear of scratching the radiator, remove the film.

Carefully connect the supplied pipes to the radiator. Fasten carefully and carefully, but do not damage the threads, otherwise you will experience water leakage from the system. Before watching, check out the installation video in our gallery.

During installation, it is important to maintain certain distances. For example, the installation height above the floor should be approximately 10 centimeters. The distance between the wall and the battery should be from 2 to 5 cm.

Results

Cast iron appliances can be safely installed in your heating systems; of course, they are inferior in characteristics to new models, but their price is low. In addition, they have proven their suitability for a whole century, both in the USSR and in Europe. The big advantage is their long service life.
