Water heating convector: choose water heating convectors wisely. Installation of an in-floor convector and installation recommendations Maintenance of a duct convector

Water heating convectors are becoming more and more common today. In addition to the fact that they are more efficient than standard heating options, they have a presentable appearance and reasonable cost. In stores, there are increasingly devices that are completely different from the usual ones.

Functions

The essence of convection is the spread of heat from heating device by air. According to all known laws of physics, heated air rises from the radiator and mixes with cold air, after which it cools and returns. The process is constantly repeated and maintains the established temperature regime in the room. While the wall convector is operating, a stable process of air mass exchange occurs.

Previously, there was a fairly large temperature difference in the lower and upper parts of the room when using such systems. AND? Thanks to the efforts of designers who tried to create a new device that would reduce this difference, such a device arose. It is assigned the following functions:

complete cutting off of cold air flows from window openings;
creating a comfortable temperature regime in room;
preventing condensation on glass;
uniform and efficient heating of the entire volume of the room.

If you pay attention to the structural elements of the device, it will become clear that it has a fundamental difference with a radiator.

Advantages

Water ones (made in Russia) can be used in premises for any purpose, despite their small dimensions and original design. The design is extremely simple, which ensures ease of installation and maintenance, and their cost is lower compared to conventional radiators.

The air in the room is uniformly heated with low coolant consumption, which makes it possible to save money. It is possible to create a coherent scheme by combining several convectors to provide uniform heat throughout the entire house.

The temperature range near the ceiling and floor does not exceed two degrees. This indicator for a traditional radiator is about +7C.

The convector, whose average price is 3 thousand rubles, has a built-in special heat sensor and thermostat, due to which the quality of the device’s operation is improved. The maximum heating level for some options can reach +80C, but few people need such a temperature.

The device is completely safe for small children, since it is impossible to get burned on it, regardless of its location.

Varieties

Water convectors are divided according to the following indicators:

fastening method and location option in the room;
the type of convection used, divided into tiers;
availability of additional devices for regulation and control;
design;
power that increases with increasing device dimensions;
height of the device.

On modern market The most widespread type is the wall-mounted water heating convector, which has forced and natural air circulation. In the latter option, the air flow, in accordance with physical laws, itself enters the heating elements, thus ensuring natural circulation.

Another type is represented by devices with fans built into the design. They provide an increase in the total volume of air entering the heating device. This improves the quality of the system itself. Safe Operation guaranteed by the voltage required to operate the fans, which is 12 volts.

Wall devices

Due to its light weight, installation of this type convectors are possible for any wall structures. Even a thin, small partition made of single-layer plasterboard material can easily bear such a load.

Wall units are compact in size, and when installed under window openings, are not inferior to any heating battery, since the unit has sufficient power due to the high speed of movement of the coolant. The design of such models usually includes special fins to increase heat transfer.

The Ballu home convector has the ability to be both wall-mounted and floor mounting. Among the advantages it is worth noting the presence of a remote control, special wheels for convenient movement, as well as frost protection function and automatic shutdown when overheating. According to customer reviews, such a device is excellent for heating bathrooms and is completely safe for children, since, due to the use of glass ceramics, the front side hardly heats up.

Built-in models

This new approach solves two problems at once - design and heating. Installation requires some construction work so that the device is not so noticeable. It is possible to construct small niches under the windows or install special channels in the floor. In any case, the prepared structures hide the parts of the convector.

Correct determination of the power required to heat a space of any size will allow you to form effective system, which will work regardless of environmental conditions. For example, in this way you can heat large Sport halls or swimming pool premises.

Built-in water heating convectors Itermic ITTL have minimal dimensions and are based on the principle of natural air flow, due to the temperature difference between cooled and heated air. Most buyers noted the high-quality assembly of the convector, silent operation, which is especially important at night, and the absence of the need to use a humidifier, since the device does not dry the air.

Floor convectors

The fastening method is main feature such devices. They are not installed on wall and other structures of the house, but are mounted anywhere on the floor - mainly next to front door or under the window.

Floor convectors have virtually no external differences from wall version. The same significant heat transfer power with a small amount of coolant used, non-standard shape and small dimensions. The installation method is the only difference. Instead of brackets, the structure is equipped with special stands.

The Electrolux ECH floor-standing device has a moisture-proof housing and a multi-stage air purification system. Based on consumer reviews, it is worth noting the quick heating of a medium-sized room and the intuitive display. Among the shortcomings, most highlighted the too bright backlight of the screen and the smell when turned on for the first time.

How to choose

First of all, you need to pay attention to power indicators. They are the same for all options and amount to 1 kW per 10 sq. m of space, while the ceiling height should be no more than 3 meters. For each window opening in the room, 0.2 kW is added. This rule does not apply to continuous glazing. When choosing a more powerful convector, the price will be higher than average and will be approximately 5-7 thousand rubles.

For a unit with installed fan, space is provided for mounting a step-down transformer device and the possibility of connecting to the electrical network alternating current. It is recommended to prepare a special place for the transformer next to the convector.

It is necessary to pay attention to the height of the device Special attention. When installing in a floor niche, you must first compare its dimensions with the dimensions of the channel. The average parameter is about 30 cm. The material used to make the case also plays a role. The floor-mounted box must be made of high-quality anti-corrosion alloys.

Wall-mounted water heating convector: design

The basis of the device is a heat exchanger; in addition to it, the design includes a casing and additional elements. The heat exchanger consists of copper tubes with coolant moving through them. Aluminum fins are attached to them, which improves the quality of heat transfer. The distance between them has a direct impact on work efficiency - it should be of medium size. The number of ribs also plays a role, but not as important as the free space between them.

For built-in options, an addition is used in the form of decorative grilles used to hide the device. Special meaning has a choice of grille - in order not to interfere with the outgoing warm air flow, it must contain slots or holes with a large area.

The valve is a mandatory component; it has a direct connection with the thermostat and is used to regulate the degree of heat transfer. It is possible to add an air vent to the design. The power of the unit is also regulated by installing additional heat exchangers.

Each part of the convector is made of metal with high degree heat transfer to increase efficiency and reduce the time required to heat up the device. It is worth noting that there are two connection options - end and side.

Installation features

If a convector for a summer residence is connected to a common heating system, installation should be carried out taking into account the nearest location of the heat exchanger. At the bottom of the case you can find special adjustment bolts. They are used to align the unit in horizontal level and height.

If it is necessary to use it as a thermal curtain, the box should be as close as possible to the window opening.

Conclusion

Modern heating techniques are quickly gaining the attention of consumers. The thing is that today, when using utility networks, the economic side has become the key point. Therefore, devices being developed that allow saving on heating costs are always of interest. A wall-mounted water heating convector falls into this category.

Installation of wall and floor options Can be done by any person who has dealt with plumbing fixtures.

In a private house correctly, without mistakes, so as not to regret it later the decision taken? First of all, you should understand what a convector is and in what cases its use is justified. There are at least four design options for these devices, and each of them has specific features. You can avoid mistakes when choosing and installing convectors if you take into account some subtleties in advance.

Heating convector - what is it?

A convector is a heating device that implements the principle of mixing air heated by a coolant with the surrounding air. Any heater is surrounded by air, so the operation of radiators is also associated with convection, but not on such a scale. To organize a convective scheme, it will be necessary to make changes to the profile of the heating system, shifting the emphasis to the movement of air flows from the direct radiation of heat by the batteries.

There are several ways to implement this:

use convectors as auxiliary devices to increase heating efficiency;
apply only convective solutions if justified by calculations;
rely on devices with forced mixing;
install convectors with natural action.

Which option will be the best? This requires calculations, but you can get a rough idea of the principle itself.

Common types of convectors

Typical mistakes when installing convectors are the result of a misunderstanding of the principle of their operation. A device that heats rooms using warm air flows can have a different design:

wall-mounted design - a convector in the form of a panel radiator with fins and at least two panels (type 21 or 22) has a passive circuit and produces at least half of the heat in the form of surface radiation;
floor convector - in the vast majority of cases, provides heating due to vertically directed air flows and radiates a certain amount of energy through top part and side surfaces;
the in-floor device operates by convection, most of its external surfaces are hidden, it is not designed to radiate heat from the side parts of the housing;
the device may have a circuit with natural convection due to the tendency of warm air upward or a system of forced air injection by a fan.

There are solutions in the form wall mounted appliances with built-in fans, but they small sizes do not allow achieving high efficiency.

Typical questions about heating with convectors

We are interested typical mistakes associated with the use of convector heating in the house. The most common questions asked by home owners about this matter well reflect the range of problems:

how to achieve maximum performance device?
Will the in-floor convector (fan coil) make a lot of noise?
At what distance from French glazing should devices be installed?
Is it possible to completely abandon radiators when using a convector?
Is it possible to use convectors together with heated floors?
How to install in-floor and floor convectors correctly?

How to properly install convectors in a heating system?

We will try to give answers point by point.

The maximum heat transfer of a heating device is a calculated parameter that depends on the characteristics of the device itself and the conditions of its use. A mistake when choosing a convector may be due to the fact that you installed a device designed for a coolant temperature of 85 C, but your heating system operates at 65 C. Taking into account heat loss during transfer, the device will not be effective.
The noise emitted by the convector is insignificant. If we are talking about the sound made by fans, then you should choose a device with speed control. There are convectors with two fan blocks and separate start, this allows you to use different power levels. High quality models convectors can be used in the bedroom and children's room without fear.
A common mistake is installing an in-floor convector close to French glazing. A gap of approximately 25 cm should be created so that the air flow spreads upward along the structure without being reflected from it. Not worth it for a long time keep the opening above the convector open, using it as a thermal curtain if it is severely frosty outside.
The greatest effect from the convector circuit is achieved when used together with emitters - radiators and a heated floor system. This is especially true for underfloor heating in areas where there are severe frosts in winter.
The two most common mistakes when installing convectors are installing a floor-standing unit on an unprepared surface and incorrectly calculating the dimensions of the recess for an in-floor convector. In the first case, you risk getting an unstable structure, knocking over the device and breaking the pipes. In the second case, part of the housing will stick out above the floor, or the convector will “fall” into the floor, and this will create difficulties with its connection.

It is very risky to undertake the installation of a convector system yourself, without skills. You should not buy appliances without preliminary calculations and a heating system design. If you have Russian convectors, you need to focus on them, since they are adapted to local conditions and meet the standards of common heating systems in terms of pressure, temperature and connection method.

Buying an in-floor convector is a responsible and expensive business; customers want to know in advance what problems they will encounter when the time comes to install an in-floor convector in their apartment or private house, we will describe the main points of installing these batteries, a feature of which is installation in the floor.

The first task for installing an in-floor convector is preparing a niche in the floor. Also, convectors that are planned to be hidden in the floor can be mounted in a false floor, that is, not in concrete screed, and for example on a wooden podium. In this case, the convector must be secured using adjusting bolts and anchors.

Let's take the most common type of installation of an in-floor battery, this is in a concrete screed. In order for the convector to be installed correctly and without problems, it is necessary to create a niche for it.

Recommendation 1: Niche for convector | Manufacturers recommend make a niche in depth plus 10-20 mm from full height convector, in order to level the convector using adjusting bolts and dock beautifully flooring(laminate tiles, parquet) with convector box. P about width and length - plus 5-10 cm from the full width of the convector box, in order to be able to firmly secure the box using anchor bolts and cement mortar.
Installation dimensions of the niche for the convector: Depth +10 mm | Width +10-15 cm | Length +5-10 cm

The location of the in-floor convector to a window with natural convection is universal, the convector can be connected to the left side and to the right side, it can simply be turned around, since the heat exchanger is located in the middle. If the heat exchanger is closer to the edge of the convector, then place it so that the heat exchanger is closer to the room.

The location of the in-floor convector to the window with forced convection by default it is considered a left-side connection; if the convector needs to be connected on the right, this must be indicated in the order when purchasing. At the manufacturer's factory, exits are made for the right side.

Recommendation 2: Spaces from windows and walls | Recommended dimensions for the location of the in-floor convector relative to the room itself and panoramic window where it will be installed. Manufacturers recommend retreat from the window 5-15 cm for efficient circulation of cold and heated air, indentations to the left and right of the walls, if there are any, are 15-30 cm. to avoid exposure to heat wall coverings(wallpaper, plaster, etc.) and of course for ease of battery installation.
Location of the convector relative to the room and window: Distance from the window 5-15 cm | distance from the side walls 15-30 cm

Recommendation 3: Curtains | There are cases when powerful curtains and curtains stand in the way of the convector, then what is better to install before or after? None of the manufacturers answer this question, so we use the recommended sizes. It is impossible for an in-floor convector to adapt to the curtains, since nothing good will come of this; the curtains must adapt to the convector. The convector should blow through the window, remove condensation and act as a thermal curtain from the cold air flow. Here are a couple of options to resolve the issues.

Recommendation 4: Isolation| Then the installer must correctly form layers of additional protection for the convector from the floor and reduce heat loss through insulation, including organizing noise insulation; you can familiarize yourself with these recommendations in this example (photo No. 1). But all these measures are not mandatory, these are recommended actions (photo No. 2) for more efficient work and operating a convector in the floor, we know from practice that many installers don’t bother and simply fill it with screed and concrete. So, when we have made a niche for the purchased convector, installed it correctly, covered it with insulating layers, filled it with concrete, we need to connect it to the heating system. There are several options for the heating system:

Connecting a floor convector to the heating system

System automatic adjustment A convector without a fan is not always effective, since it is necessary to strictly follow the instructions stated by the manufacturer, otherwise the automation will not effectively regulate the convector.

The regulator measures the room temperature using a built-in sensor and maintains the set temperature value. When the room temperature drops below the set value on the thermostat, the thermal servomotor will open the valve. The room temperature controller should be located in such a way that the temperature measurement is as accurate as possible, without exposure to solar radiation or sources of heat and cold. Installation should be carried out at a height of about 1.5 m above the floor. It is prohibited to install a thermal head in the floor convector itself.

Trench convectors electrical connection

If you have a convector with a fan, then you additionally need to connect electricity to the convector to be able to control the fans. For each convector it is purchased additional module convector, popularly also called a transformer, where you need to supply 220 V, and from it either 220 V goes to the fans or 12 V, depending on the manufacturer. This module also controls the room thermostat and vice versa. The thermostat automatically commands the fan to turn on if the room temperature drops below the set point on the thermostat. A room thermostat measures the temperature in the room using a built-in sensor and maintains its value at a set value. In parallel with this, the room controller can control servos and also regulate the fan speed. You can read about this in article about managing in-floor convectors.

If you absolutely do not want the convector module to be outside the convector, then you can consider Verano, their modules are mounted directly into the convector box.

On the trail. In the screenshots, you can clearly see several connection diagrams for the electrical part of the in-floor convector. These diagrams are visual and are used for different manufacturers floor convectors, it is mandatory to coordinate the diagram with an electrician or our specialist. Each manufacturer has its own modules, its own recommended room thermostats, so you must rely on the manufacturer. You can request an exact diagram from our specialists, who will provide it to you.

Installation of decorative grilles and frames

The final element of the trench convector is the elegant grille. It can be without a frame, or with a frame (U-shaped and F-shaped). Wooden gratings can be made exclusively from natural wood. To protect grilles made of wood, it is recommended to use staining and varnishing. Aluminum grilles are more wear-resistant, as they are made of aluminum and undergo an anodizing process. Customers often ask which grating is more durable; in fact, all gratings are durable, both wooden and aluminum, and can withstand loads of 40 kg or more. one bar. The only point is that wood is more susceptible to external wear, that is, abrasions from walking on it will be more visible, and it is more easily soiled since it is wood.

All manufacturers additionally offer a convector option with a decorative frame, a frame, in order to close the joints between the floor covering and the convector itself in the floor. As with everything, there are advantages and disadvantages. The advantage of using a decorative frame in a convector is the closing of the joints; often tilers do not perfectly fit the tiles to the convector, leaving gaps and cracks. That's when framing helps. There are two types, U-shaped and F-shaped. The U-shaped one is less noticeable, since it does not lie on the floor covering, while the F-shaped one lies on top, has a width of 1-2 mm, thereby completely hiding the joint between the convector and the floor. But in this case, the grate is slightly higher than the floor, that is, a slight rise is formed. If without a frame, then the floor, convector and grille are on the same level.

The cost of installation and installation of an in-floor convector is approximately $100. USA, depending on the complexity of the work, which is assessed by the installer.

Video installation and in-floor convector

Every time there are more and more videos on the Internet about the installation and connection of in-floor convectors, we have selected them at this moment the most informative and understandable. Enjoy watching.

When planning to create heating in our home, we want it to be economical and efficient. Convector heating has precisely these characteristics - it is based on convectors powered by bottled or main gas, water systems or from electrical outlet. Let's see what convectors are, how they work and how they differ from each other. We will also look at the main features of convector heating of residential premises.

What is convection

Convective heating uses the most simple laws physics, according to which heated air becomes lighter and rises. Every heating convector is built on this principle, regardless of what it is powered from. As practice shows, this scheme is highly effective - residential premises become warm, and relatively quickly.

Convector heating allows you to heat rooms for any purpose - these can be living rooms, children's rooms, corridors and foyers, kitchen areas, bathrooms and toilets, covered balconies and loggias. It heats using heated air, quickly saturating the heated rooms with heat. Let's see how the warming up process occurs:

All convectors work on the same principle - they create air circulation in the room, gradually warming it up.

With a large working surface area, a heating element heats the air around it;
Warm air masses rise upward, leaving the equipment (or simply going upward if convector-type heating radiators are used);
Cold air masses replace the air that has gone up.

The process is repeated until convector heating warms up all the air in the rooms.

Heating elements can be powered by electricity or by combustion gas fuel. Convector-type heating batteries operate due to the coolant entering them. By the way, the batteries do not have housings, unlike the same electric and gas convectors. But their operating principle is similar - heating is carried out due to the heating air, and the thermal radiation from them is very weak.

Advantages and disadvantages of convector heating

Let's take a look at what the main advantages of convector heating are and try to present all the advantages in the form of a list:

Installation of electric convectors is one of the most quick ways organize constant heating of a private house.

Possibility of heating premises for any purpose;
No impact on air (convector heating does not burn oxygen);
Low impact on air humidity;
Ease of installation of equipment (typical for electrical appliances);
Absence negative influence for your well-being(this is how a convector differs favorably from an IR heater);
Large selection of heating equipment.

There are also certain disadvantages:

Convector heating has little effect on air humidity. However, this is typical for many heating devices;
Some people don't like the feeling of overheated air;
Low efficiency in rooms with high ceilings;
High temperature difference in the lower and upper parts of the rooms.

If we take into account electric convector heating, it is characterized by another disadvantage - high cost. But if the house does not have a gas main, and you want the heating system to be inexpensive and easy to install, then you cannot do without convectors.

Types of convectors

Let's see what you need to create convector heating in your home. Ready system May be:

Water - using convector heating radiators, with pipes and a boiler (electric, gas, solid fuel or liquid);
Electric – here we mean the installation of electric convectors;
Gas - special gas convectors are installed in the rooms, most often powered by bottled gas.

Let's talk about these convectors in more detail and find out distinctive features certain convector heating systems.

Convector heating radiators

Many people remain committed classical systems heating, laying pipes in houses and installing boilers. If there is gas in the house, then this is even a plus - after all water heating, built on the basis gas boiler, is the most inexpensive and economical. Approximately the same can be said with regard to heating based on boilers running on liquefied gas. The next leader in terms of efficiency is solid fuel equipment.

Solid fuel boilers can work completely free of charge if you prepare firewood in advance from the nearest forest. If there are no clearings nearby, you can limit yourself to purchasing fuel in bulk - it will be cheaper.

Convector water heating involves the use of radiators connected to pipes laid throughout the house. The hot coolant entering the batteries heats up the metal, after which the heat is transferred to the surrounding air. It rises up, and cold air masses take its place. Temperature control in such heating systems is carried out in general procedure(regulated by the boiler) or privately (using taps and valves on batteries).

Considering the complexity of conducting installation work, we recommend the use of water convector heating in buildings with a large number of rooms - here the installation of dozens of autonomous electric convectors is not justified. It is also recommended for homeowners connected to gas mains and those who have access to inexpensive solid fuel.

Electric convectors

It is very easy to build convector heating based on simple electric convectors. The entire installation process boils down to the following steps:

Brackets are mounted on the wall;
Convectors are hung on brackets;
The equipment is connected to the electrical network.

If in front of us is a miniature country house with one room, then installation work will take a maximum of half an hour - it is more difficult to extend an outlet to the installation site than to connect a convective device.

Electric convectors operate from the electrical network. Unlike the convector heating batteries described above, they do not contain coolant or any other liquids. Heating here is carried out by finned heating elements installed in the lower part of the heating devices. Air is taken in through the lower slot openings and removed through the upper ones.

The operation of convector heating is controlled by automation - it can be mechanical or electronic. Mechanical thermostats operate on the principle of a bimetallic plate. As soon as the temperature reaches the set value, the plate will bend and open contact groups. If the air cools down, the opposite will happen - the contacts will close and the heating element will continue to operate. Here it is not the temperature that is set, but the degree of heating (for example, using numbers from 0 to 9).

Electronic thermostats are built on the basis of control modules with sensors, microcircuits and other electronics. They carefully control the air temperature, giving commands to turn the heating elements on/off. This work scheme has the following advantages:

Convectors receive additional functionality - timers, anti-freeze, program operation, etc.;
Economical – electronic convectors provide up to 5-10% energy savings;
Ease of creating a comfortable atmosphere - the temperature can be adjusted with an accuracy of 0.5-1 degrees.

Convector heating based on electric convectors is recommended for use in small and medium-sized non-gas houses. Its main disadvantage is the high cost - for heating even the most small house within a month you will have to pay several thousand rubles.

Gas convectors

We come to the last equipment from our review - gas convectors. They can operate on both main and liquefied gas. The principle of their operation is very simple:

A gas burner burns gas to produce heat;
Under the influence of the flame, the metal radiator begins to heat up;
The ribbed radiator begins to heat the air;
Then the simplest convection works - we considered this principle at the very beginning of the review.

Convector heating based gas convector cannot be called the most common approach for heating residential buildings. Rather, this is the rarest option, since such units are not widespread.

Used in such devices gas-burner requires removal of combustion products - for this they are equipped coaxial chimneys, leading directly beyond the wall. Accordingly, there are as many chimneys as there are devices in the house. This approach cannot be called optimal, but if the task is to heat a small country house or country house with 1-2 rooms, then it will best option. For heating big houses such equipment is not suitable.

The most commonly used fuel here is liquefied gas, connected via a flexible hose. If convector heating involves installing several gas appliances, we recommend laying a small gas line above the floors to distribute fuel to all convectors. This scheme will allow you to power several gas appliances from one cylinder.

Classmates

Sometimes use electric convector- the only acceptable way to heat a private home.

At the same time, work may require high power consumption.

The reasons for this may be:

Wrong choice of device- at large area In the room the power is too low, the convector works constantly, without interruptions. This situation threatens rapid failure of the device.
Lack of operating mode controller. There are models that do not have the ability to adjust the temperature and operate constantly at maximum mode.

Both situations are extremely inconvenient for the user, since you have to periodically turn off the device manually to prevent overheating of both the device and the room. If there are many such devices, then you have to constantly turn the convectors on and off, which is inconvenient and requires the use of some kind of control unit. Energy-saving electric convectors can be a solution to the problem.

Thermoregulator (thermostat) is a device that performs automatic shutdown or turning on the convector when the set temperature limits are reached. The operation of the thermostat, depending on its design, can be fully or partially automatic. Some models have the ability to precisely program temperature, start time and operating mode.

There are situations when maintaining an accurate temperature regime is necessary - for example, if there are houseplants, demanding to a certain humidity and temperature regime. At the same time, there are more simple devices, allowing approximate step-by-step temperature control or not having such a function at all. They have a lower price and are used as auxiliary devices for local or household purposes.

The operation of the thermostat allows you to set a certain mode. Different models have their own modes or programs, the most common of which are::

Economic mode. It operates in a minimum temperature range, heating is performed only to maintain life functions.
Comfort mode. Provides the most convenient and pleasant heating for a person.
Maximum mode. The most powerful heating, used to quickly heat rooms after a long absence or during severe frosts.

In practice, the list of modes is much wider; they vary greatly on different devices. The better and more expensive the model, the more accurate the temperature setting and more options thermostat settings.

Types of thermostats

Controlling the operation of an electric convector is an important task that requires the use of reliable and accurate devices.

The development of such devices began a long time ago, even before the advent of electric convectors.

Currently used Various types thermostats that have varying degrees of accuracy, reliability and operate on different principles.

The following types of thermostats are used for electric convectors::

Mechanical. Electric convectors with a mechanical thermostat are the most simple design, the thermocouple principle or others is used mechanical methods shutdowns. The adjustment is mainly stepwise, but there are also devices with smooth adjustment. The most affordable, they do not have the ability to program or accurately set the temperature.
Electronic. Electric convector with electronic thermostat controlled using an electronic unit that allows precise temperature setting, a choice of operating modes, etc. Depending on the model or manufacturer, such thermostats are relatively expensive, but they have a number of capabilities that are not available for mechanical thermostats.
Programmers, control units. Additional devices that allow you to combine several convectors into groups with a single control. They have the ability to program several days or weeks in advance.

Most good choice is an electric convector with an electronic thermostat, which has high accuracy of temperature setting and a lot of possibilities for providing the most comfortable heating mode for the house. For models that do not have thermostats, you can, if necessary, purchase a separate control module, connecting to which will switch the operation of the device to automatic mode.

Advice. The choice of device should be based on the purpose of the device - constant or periodic heating, local or part of the system. For periodic additional inclusions, you can get by with simpler and cheaper models.

Fan

You can also purchase an electric convector with a fan.

The fan is used in some convector models to perform the following tasks:

increased air flow, making the convector more efficient;
cooling of the heat exchanger, reducing the risk of burns from accidental contact;
cooling the heater, increasing its service life.

These functions allow you to make the convector work more intensively, but for a short period of time. That is, the temperature of the heater can be increased because it is cooled by the air flow from the fan blades, warm air has a higher output speed, which requires much less time to heat the room to the desired state.

Therefore, with the same results, the time of one period of operation of a ventilated convector is significantly reduced compared to devices using natural convection.

Attention! The use of fans makes the device somewhat noisier, which may be noticeable at night.

Energy saving

The operation of the thermostat is aimed at solving two problems:

Ensuring the most comfortable room temperature.
Energy savings due to the periodic nature of operation.

If the primary heating of the room requires the use of the maximum mode, which allows the temperature to rise to acceptable values in a short time, then to maintain a comfortable mode you only need to periodically turn on the appliances and slightly heat the air.

Therefore, with long-term use of the convector, electricity consumption does not increase like an avalanche, but has a fairly even character.

To guarantee energy saving, it is necessary to choose electric energy-saving heating convectors of sufficient power so that they can be switched off periodically and do not constantly consume energy at maximum speed.

Energy consumption can be calculated based on the power of the device. That is, if the convector has a power of 1.5 kW, then per hour of operation in maximum mode it will consume 1.5 kW/h. But this is the maximum possible energy consumption; in practice, this does not happen. In fact, the device only works until the set temperature is reached.

It's time for different models may differ, so it’s easier to proceed from the generally accepted formula: energy consumption at an outside temperature of -20°C is about 70-80% of the calculated value, i.e. at 100 W of power per 1 sq. m. area.

Thus, the consumption per 20 sq. m. at -20 degrees outside will be 1.4-1.6 kW. Some sources indicate much lower values, claiming that intermittent operation saves 40 to 70% energy. It’s difficult to argue with this, but it would be more correct to accept higher value to avoid spending more than planned.

Prices

When purchasing electric heating convectors with a thermostat: the price and quality of which are at the proper level, you should take into account some points.

For example, prices for electric convectors have a wide range, from the most budget to very high.

At the same time, the dependence of price on the quality of the device is not always maintained; the main criterion in pricing is the country of origin and brand. It is best to purchase a device from large companies or stores that have a warranty on the device and do not sell models from dubious companies.

The cost of an electric convector depends on such factors:

manufacturer level;
heating device power;
complexity of the device design;
type of thermostat.

Models with mechanical thermostats have lower prices starting from 1,000 rubles and above. To purchase an electronically controlled convector, you will need 2,500 rubles or more, depending on the characteristics of the device. Buying a convector is a serious matter, since the right model will help save money spent on heating, providing complete coziness and comfort in your home.

When choosing a device, you should take into account the number of devices for complete heating of the house, their power and operating conditions. When choosing power, the opposite rule applies: more power means less operating time and, as a consequence, lower energy costs. However, purchasing devices with too high specifications can exceed the load on the network and have undesirable consequences.

Attention! When purchasing you should adhere to general principle- you should not purchase the cheapest and most expensive models. The rule of the “golden mean” has never failed.

conclusions

The thermostat of an electric convector is a necessary and useful element of the heater design, which allows you to automate the operation and control of devices. At the same time, the main problem remains - dependence on the presence of voltage in the network, which requires attention and is solved by using thermostats with the function of automatically starting the device when the current is temporarily turned off.

Electric convectors with thermostats (mechanical regulators) are used for local auxiliary heating; they should not be used for full heating of the house, since the failure of one thermostat can lead to a failure of the entire system or the operation of one device at full capacity, which means high costs. It is most convenient to combine devices into groups with general management to avoid tedious adjustment of each convector separately.
