Manual heating thermostat. Thermostat for radiators. Thermostat control device - thermal head

To ensure optimal temperature conditions in the room and optimize utility costs, it is necessary to regulate the rate of flow of coolant into the radiator. Heating battery thermostats do an excellent job of this task.

Let's look at the features of the operation and installation of various types of thermostats, and determine the main criteria for choosing a high-quality, reliable battery thermostat.

The need to use a battery thermostat

When arranging a heating system, many people ask the question: “Do I need a thermostat for the battery?” Today, when bills for heat consumed by the population are steadily increasing, the answer is unequivocal: “Yes.”

Very often, residents of multi-storey buildings are forced to open the windows in the winter to reduce the heat from heated radiators. Coolant energy is wasted irrationally. This is especially noticeable for those who have heat meters installed.

The thermostat (thermostat) of heating batteries is a device that controls the microclimate in the room. Some models have the ability to program temperature conditions for different times of the day (day/night) and for each individual day.

Using a thermostat and a heat meter in combination is an effective way to reduce the cost of heating a room

Additional advantages of battery thermostats include:

The purchase and installation of a battery thermostat in private houses and cottages pays for itself in one heating season

Installing a thermostat for radiators in heating apartments is especially important for rooms with significant temperature fluctuations: kitchen, living room and “sunny” rooms.

Types of thermostats: design and principle of operation

Let's consider the classification of thermostats for batteries according to two main criteria:

1. According to the adjustment principle:
   • mechanical;
   • automatic.
2. According to the type of working substance of the thermal head:
   • gas-filled;
   • liquid.

Mechanical thermostats

A mechanical thermostat for a battery consists of two main parts:

• thermostatic valve;
• high sensitivity element (thermal head).

The mechanism works smoothly and reliably without attracting external energy. The thermal head includes: a regulator, a drive, and a gas or liquid working element.

The operating principle of a mechanical thermostat is as follows:

1. Under the influence of temperature, the volume of coolant in the heating system changes.
2. The bellows senses the changes that have occurred and moves the control valve. The movement of the spool is associated with any change in room temperature.

The sensitive element (liquid, gas) reacts by moving the rod - such a change in stroke allows you to regulate and control the flow of coolant into the radiator.

Various factors can affect the operation of the thermostat:

• draft or ventilation of the room;
• outside temperature;
• sunlight;
• the presence of other sources of heat or cold near the thermostat (refrigerator, heater, hot water pipeline).

Electronic thermostats

Electronic thermostats are programmable microprocessor devices for regulating and maintaining the temperature of a home. The thermostat automatically controls the elements of the heating system (pump, boiler, mixer). The consumer just needs to set the desired temperature, and the built-in sensor will regulate it throughout the heating season.

The main element of an electronic thermostat is a temperature sensor, which transmits information about the temperature indicators of the zone in which it is installed. The thermostat reacts to the information and optimizes the mode to the set temperature.

Digital thermostats with closed and open logic are widely used.

Electronic thermostats with closed logic have a constant, clearly defined operating algorithm that does not depend on environment. You can only manage basic parameters. For domestic use, such a thermostat is quite sufficient.

Electronic thermostats with open logic have free programming and are able to adapt to any system in which it will be involved. More often, such devices are used in industrial areas, since programming and changing settings takes a lot of time and must be performed by highly qualified specialists.

They are often used in everyday life conventional electronic thermostats, similar to their mechanical counterparts, but with an electronic display. They operate in simple mode. For their operation, it is enough to set the temperature, which will be constantly maintained, or set the permissible range of temperature fluctuations.

Electronic thermostats operate on batteries and come complete with a charger.

Liquid and gas-filled thermostats

The working substance of the thermal head is usually gas or liquid (paraffin). It must be said that cheaper and more common are liquid thermostats. However, gas-filled thermostats respond more accurately and quickly to changes in pressure inside the bellows.

Advantages of the gas-filled thermostat design:

• gas condensation occurs in the cooled part of the device, remote from the valve body, so the operation of the thermostat does not depend on the temperature of the water (coolant);
• The thermostat is very sensitive to temperature fluctuations in the room, which allows you to effectively control heat supply.

Installing thermostats on radiators

Thermostat installation diagrams for one- and two-pipe heating systems

When installing a thermostat on a battery in a single-pipe system, you will have to change the radiator connection diagram and install an additional jumper - a bypass.

The bypass will connect the direct and return coolant supply. This will allow the coolant to circulate while the battery is shutting down. In addition, it will be possible to dismantle the radiator - just close the valves (3 and 4 in the figure).

In a two-pipe heating system, the thermostat is installed on the upper supply pipe, and a valve is mounted on the lower one.

Explanation of symbols:

• supply riser;
• battery;
• mechanical or electronic thermostat;
• bottom valve;
• air vent;
• bypass (jumper);
• return riser;
• stub.

Rules for proper installation

The thermostat will work smoothly and efficiently if it is installed correctly and in compliance with all the rules:

Sequence of installing the thermostat on the battery

Let's consider the step-by-step installation of a thermostat on a heating battery:

The bypass diameter should be one size smaller than the diameter of the supply pipes. For example, for a ¾" pipeline, the diameter of the closing section should be ½"

Setting up the thermostat

After installation, the mechanical thermostat must be configured to set the optimal temperature in the room. To do this, perform the following steps:

With electronic thermostats, you just need to set the desired temperature on the display. If the functionality allows, you can select the temperature mode for daytime and nighttime, for different days of the week, for example, intensive heating of the room on weekends, and economical heating on weekdays. This mode is optimal for country houses and dachas, where the owners appear only on the weekend.

In order to buy a thermostat for a heating battery and not regret your purchase over time, you need to take a responsible approach to choosing a thermostat and take into account some important points:

Particularly effective, from an economic point of view, is the use of battery thermostats in private houses and cottages with autonomous heating; in apartments with a centralized coolant supply, the use of thermostats makes it possible to improve the microclimate of the room by establishing a more comfortable temperature regime.

In order to more rationally use resources and, accordingly, reduce the cost of heating a room, heating systems are equipped with a special device known as a heating temperature controller. The design of such a device is extremely simple, and installation can be done with your own hands, even without special skills.

Although there are more expensive mechanical devices. So, Legrand Etika 672630 costs as much as 7750-10600 rubles.

As you can see, you always have to pay more for quality, and our case is no exception. But we note that mechanical models are still simpler and, accordingly, cheaper. Now let’s find out how to properly install the heating temperature regulator.

Classification of thermostats

Regulators used in heating can be:

1. electronic;
2. mechanical;
3. electromechanical.

Each option has its own strengths and weaknesses, let's look at them in more detail.

Electronic devices

In this case, the regulator consists of three main parts:

1. temperature sensor;
2. microprocessor;
3. key

A temperature sensor is needed to measure air temperature, the processor receives and converts the signal, and the key creates control communication. The advantages of electronic models include:

1. high accuracy;
2. ease of settings and control of heating systems.

They are used not only to control the heating system or regulate the operation of air conditioners, but also in other equipment designed to create a comfortable microclimate. What’s remarkable is that they can even be integrated into a “smart home” system.

Mechanical devices

A heating temperature regulator of this type consists of:

1. thermal head;
2. valve

Both parts function smoothly and no extraneous energy is used. In turn, the head includes:

1. drive unit;
2. gas or liquid element;
3. and finally the regulator.

The scheme of its operation is extremely simple: by means of manual control, a small wheel with temperature is set to the required level. It is typical that instead of such a wheel, an off/on key can be used, but in any case, the devices are controlled manually.

Electromechanical type devices

They are rightfully considered the simplest temperature regulators. Their main structural element - the relay - can be of several types, but in heating the one in which some elements expand when heated occurs.

Can be used in water heaters and oil coolers in which the relay is shaped like a cylinder filled with a sensitive substance. The tube itself is placed in a small container with heated water.

Installing a heating temperature controller - step-by-step instructions

First, prepare everything you need for your work:

1. grinder or electric jigsaw;
2. sanitary paste;
3. spanners;
4. clamps for pipes.

All this needs to be prepared in advance so as not to be distracted during the installation process. The installation itself is extremely simple - the procedure consists of four main stages.

First, prepare the battery for installation work. Turn it off and drain all the working fluid. If there is a valve, remove it.

Note that in single-pipe systems there is a mandatory bypass - a special jumper, thanks to which the liquid will circulate through the main line even when one of the devices is turned off. In this case, you will not be able to disrupt the heating of other rooms in the house.

Installation of thermostat. In this case, you will use a threaded connection, and the thread itself must be sealed with plumbing flax, having previously impregnated the latter with paint. First, screw the device into the radiator hole, which is intended for introducing working fluid. Do not apply too much pressure, otherwise you may damage the device.

Note! On the valve you will be able to see a marking in the form of an arrow. Make sure it points in the direction in which the coolant will move.

Install a thermostatic element - a device that determines the air temperature in the room. Its other function is to control the operation of the locking mechanism. Fix it only horizontally! Also make sure that the heat generated by the battery does not directly affect the temperature sensor.

But if, for one reason or another, horizontal installation is impossible, then we advise you not to do it “haphazardly”, but to purchase a special device with a remote temperature sensor. Such a device can be installed two meters from the heating radiator, and sometimes even more.

There are a number of requirements regarding the installation of a temperature sensor. Here they are.

1. The device should be installed at least 80 centimeters from the floor surface, since cold air, as we remember from physics lessons, accumulates from below. And if the sensor comes into contact with this air, its readings may be inaccurate.
2. Do not cover the temperature sensor with curtains, furniture or other interior items.
3. Avoid exposing it to direct sunlight.
4. Finally, do not allow the device to be exposed to direct flows of heated air, which, it is worth noting, can come not only from the battery, but also from various types of household appliances.

Note! If the sensor is remote, then it is secured with brackets. It is also important that the installation location is selected correctly.

If all these requirements are met, the heating temperature controller will work properly and efficiently.

Set up the thermostat and prepare it for use. After turning on the heating system for the first time, configure and calibrate the device. Do this in full accordance with the manufacturer's instructions for your specific model, as this process may differ for different devices. Although there is a general rule: you can start tuning only after each of the heating devices in the system has warmed up thoroughly.

As you can see, there is nothing complicated in installing a temperature controller. Having understood its structure and done everything as stated in the instructions, in the future you will be able to control the intensity of heating the room, thanks to which energy resources will be spent extremely rationally. And this, in turn, will help to significantly save on heating costs.

Video - Installation of a heating thermostat

And now - in more detail about the setup.

How to set the temperature controller

First, you need to make sure that heat loss in the room is minimal - close every door and window in your home. Place a thermometer in the place where you plan to get a constant temperature.

Open the valve - turn the device head to the left until it stops. The fact is that it is in this position that the heat transfer of the heating devices will be at its limit, and the air in the room, accordingly, will begin to warm up.

As soon as the temperature rises by about 5 degrees, turn the valve to the right, also all the way. After this, the temperature will drop and, as soon as it reaches the desired level, open the valve again, but this time slowly. As soon as you hear the water making noise in the regulator and feel that the valve itself is already hot, stop rotating the head and put its location in memory. That's it, now you have configured the heating temperature controller!

Note! If you are interested in how the device is removed from the battery, then the answer is: you need to turn the nut located behind the plastic head counterclockwise, and then replace it with a new one. Extremely simple.

Operating principle of the temperature controller

The thermostat for heating radiators consists of a thermostatic head and a valve, the latter playing the role of a so-called actuator. The head, in turn, consists of a cylinder filled with a working substance that is sensitive to temperature fluctuations. Actually, thanks to this, the thermostat performs its function.

When the temperature rises, the volume of the working fluid increases, and if it decreases, then vice versa. During this, the pressure rod, which is connected to the cylinder, moves. The thermostatic head is installed on the valve. When expansion/compression occurs, the rod releases or compresses the locking cone located under the spring (this cone is necessary to close/open the hole through which the coolant is supplied).

The regulator can operate on a liquid or gaseous working substance; according to this parameter, in fact, all devices are divided into two large groups. Gas-filled thermostats are more sensitive to temperature changes, but liquid thermostats respond more accurately to pressure surges in the device, so the temperature can be adjusted with maximum accuracy.

Note! The principle of operation of the regulator is the same for all heating systems - both single- and double-pipe. The only difference is the resistance of the valves: in the first case it is significantly lower than in the second.

Main advantages

Modern models of thermostats have many advantages, the main one of which is extreme ease of operation. The devices are quite easy to install and just as easy to use, and all the nuances can be quickly understood. A modern heating temperature regulator creates a cozy and favorable environment in the home, and also makes it possible to significantly save on heating and use energy resources more efficiently.

But creating a comfortable microclimate is not the main thing, because heat savings also occur. For example, in an apartment heated through a centralized system, you need to install not only a thermostat, but also a heat meter, but in private houses with autonomous heating, all savings come down to reducing the amount of energy consumed (not without the help of regulators, of course).

Note! If you are just designing a heating system, it is better to buy radiators with built-in thermostats. Although installing a thermostat in a finished system, as we have already noted, is also not difficult.

We will talk about the installation a little later, but now we will look at the main types of devices.

Features of choosing a temperature controller

In order not to regret your purchase in the future, we advise you to approach the choice of device with full responsibility and take into account a number of important nuances.

Video - Heating temperature regulators

In conclusion, we note that any heating system is designed to create a comfortable microclimate in the home. And each room requires a different temperature - it all depends on their purpose. Moreover, it must be permanent.

Warm winters and good luck at work!

Adjusting heating radiators in an apartment allows you to simultaneously solve several problems, the main one of which is to reduce the cost of paying for certain utilities.

This possibility is realized in different ways: mechanically and automatically. However, when changing the heating system parameters, the average room temperature does not increase. You can only reduce it to the desired level by adjusting the position of the fittings. It is advisable to install such devices on batteries in houses where it is cool in winter.

Why do you need to make adjustments?

The main factors explaining the need to change the heating level of batteries using locking mechanisms and electronics:

1. Free movement of hot water through pipes and inside radiators. Air pockets may form in the heating system. For this reason, the coolant stops heating the batteries, as it gradually cools. As a result, the indoor microclimate becomes less comfortable, and over time the room cools down. To maintain heat in the pipes, shut-off mechanisms installed on radiators are used.
2. Adjusting the temperature of the batteries makes it possible to reduce the cost of heating your home. If the rooms are too hot, by changing the position of the valves on the radiators you can reduce costs by 25%. Moreover, reducing the heating temperature of the batteries by 1°C provides savings of 6%.
3. In cases where radiators heat up the air in the apartment very much, you have to open the windows often. It is not advisable to do this in winter, because you can catch a cold. To avoid having to constantly open windows in order to normalize the microclimate in the room, regulators should be installed on the batteries.
4. It becomes possible to change the heating temperature of radiators at your discretion, and individual parameters are set in each room.

How to regulate radiators

To influence the microclimate in the apartment, you need to reduce the volume of coolant passing through the heating device. In this case, it is only possible to reduce the temperature value. The heating system is adjusted by turning the valve/faucet or changing the parameters of the automation unit. The amount of hot water passing through the pipes and sections is reduced, and at the same time the battery heats up less intensely.

To understand how these phenomena are interconnected, you need to learn more about the operating principle of the heating system, in particular, radiators: hot water entering the heating device heats the metal, which, in turn, releases heat into the air. However, the intensity of heating the room depends not only on the volume of hot water in the battery. The type of metal from which the heating device is made also plays an important role.

Cast iron has a significant mass and releases heat slowly. For this reason, it is not advisable to install regulators on such radiators, since the device will take a long time to cool. Aluminum, steel, copper - all these metals instantly heat up and cool down relatively quickly. Work on installing regulators should be carried out before the start of the heating season, when there is no coolant in the system.

In an apartment building, there is no way to change the average water temperature in the heating system pipes. For this reason, it is better to install regulators that allow you to influence the microclimate in the room in a different way. However, this cannot be realized if the coolant is supplied from top to bottom. In a private house there is access and the ability to change individual equipment parameters and coolant temperature. This means that in this case it is often impractical to mount regulators on batteries.

Valves and taps

Such fittings are a heat exchanger of a shut-off device. This means that the radiator is adjusted by turning the tap/valve in the desired direction. If you turn the fittings 90° all the way, the flow of water into the battery will no longer flow. To change the heating level of the heating device, the locking mechanism is set to the half position. However, not every fitting has this opportunity. Some faucets may leak after a short period of use in this position.

Installing shut-off valves allows you to manually regulate the heating system. The valve is inexpensive. This is the main advantage of such fittings. In addition, it is easy to operate, and changing the microclimate does not require special knowledge. However, there are also disadvantages to locking mechanisms, for example, they are characterized by a low level of efficiency. The battery cooling rate is slow.

Stopcocks

A ball design is used. First of all, it is customary to install them on a heating radiator in order to protect housing from coolant leakage. This type of valve has only two positions: open and closed. Its main task is to turn off the battery if such a need arises, for example, if there is a risk of flooding in the apartment. For this reason, shut-off valves are cut into the pipe in front of the radiator.

If the valve is in the open position, the coolant circulates freely throughout the heating system and inside the battery. Such taps are used if the room is hot. The batteries can be turned off periodically, which will reduce the air temperature in the room.

However, ball locking mechanisms must not be installed in the half position. With prolonged use, the risk of leakage in the area where the ball valve is located increases. This is due to gradual damage to the locking element in the form of a ball, which is located inside the mechanism.

Manual valves

This group includes two types of fittings:

1. Needle valve. Its advantage is the possibility of half installation. Such fittings can be located in any convenient position: completely opens/closes the access of coolant to the radiator, significantly or slightly reduces the volume of water in heating devices. However, there is a drawback to needle valves. Thus, they are characterized by reduced throughput. This means that after installing such fittings, even in a fully open position, the amount of coolant in the pipe at the battery inlet will be significantly reduced.
2. Control valves. They are designed specifically to change the heating temperature of batteries. The advantages include the ability to change position at the user’s discretion. In addition, such fittings are reliable. There is no need to frequently repair the valve if the structural elements are made of durable metal. There is a shut-off cone inside the valve. When you turn the handle in different directions, it rises or falls, which helps to increase/decrease the flow area.

Automatic adjustment

The advantage of this method is that there is no need to constantly change the position of the valve/faucet. The desired temperature will be maintained automatically. Adjusting the heating in this way makes it possible to set the desired parameters once. In the future, the heating level of the battery will be maintained by an automation unit or other device installed at the input of the heating device.

If necessary, individual parameters can be set multiple times, which is influenced by the personal preferences of the residents. The disadvantages of this method include the significant cost of components. The more functional the devices are for controlling the amount of coolant in heating radiators, the higher their price.

Electronic thermostats

These devices superficially resemble a control valve, but there is a significant difference - a display is built into the design. It displays the room temperature that needs to be obtained. Such devices work in conjunction with a remote temperature sensor. It transmits information to the electronic thermostat. To normalize the microclimate in the room, you just need to set the desired temperature value on the device, and the adjustment will be performed automatically. Electronic thermostats are located at the battery input.

Adjusting radiators with thermostats

Devices of this type consist of two units: lower (thermal valve) and upper (thermal head). The first of the elements resembles a manual valve. It is made of durable metal. The advantage of such an element is the ability to install not only an automatic, but also a mechanical valve, it all depends on the needs of the user. To change the heating temperature of the battery, the design of the thermostat includes a bellows, which exerts pressure on the spring-loaded mechanism, and the latter, in turn, changes the flow area.

Using Three-Way Valves

Such devices are made in the form of a tee and are intended for installation at the connection point of the bypass, the inlet pipe to the radiator, or the general riser of the heating system. To improve work efficiency three-way valve is equipped with a thermostatic head, the same as that of the previously discussed thermostat. If the temperature at the valve inlet is higher than the desired value, the coolant does not enter the battery. Hot water is directed through the bypass and passes further along the heating riser.

When the valve cools down, the passage hole opens again and the coolant flows into the battery. It is advisable to install such a device if the heating system is single-pipe and the pipe distribution is vertical.

To be able to regulate the temperature of the battery in the apartment, consider any type of valve: they can be straight or angular. The installation principle of such a device is simple; the main thing is to correctly determine its position. Thus, the direction of coolant flow is indicated on the valve body. It must correspond to the direction of water movement inside the battery.

Place valves/thermostats at the inlet of the heating device; if necessary, install a tap at the outlet as well. This is done so that in the future it will be possible to independently drain the coolant. Regulating devices are installed on heating radiators, provided that the user knows exactly which pipe is the supply pipe, since a tap is made into it. In this case, the direction of movement of hot water in the riser is taken into account: from top to bottom or from bottom to top.

Compression fittings are more reliable, which is why they are used more often. The connection to the pipes is threaded. Thermostats can be equipped with a union nut. To seal the threaded connection, use FUM tape or flax.

The main task of the heating system is to maintain a comfortable air temperature in the building. This temperature may vary depending on the purpose of the room, but a prerequisite is that it remains constant throughout the day.

Indoors thermal energy comes from the heating system through radiators. The volume of thermal energy given off by heating devices is regulated by the amount of coolant.

The device that regulates the flow of liquid entering the radiator is a valve or valve, which can be automatic or manual.

There is always heat exchange in the room with the surrounding space. This leads to an outflow or inflow of heat from the room, and, consequently, to a decrease or increase in air temperature in it.

To restore the thermal balance in the room, it is necessary to increase or decrease the amount of heat supplied from heating devices. A battery thermostat installed on the supply pipelines will cope with this task perfectly.

Mechanical thermostat

This device consists of a valve and a sensing element (thermal head). They function smoothly without extraneous external energy. The thermal head is equipped with a drive, a regulator and a liquid element, which can be replaced with an elastic or gas one.

It is necessary to select a thermostat for a battery taking into account all factors that may subsequently affect its operation. It is important to make a special calculation - only in this case will this device function as efficiently as possible.

Components

The battery consists of the following elements:

• Compensation mechanism.
• Stock.
• Detachable connection.
• Spool.
• Sensitive element.
• Thermostatic element.
• Tuning scale.
• Union nut.
• A ring that fixes the desired temperature.

Impact factors

The following factors can affect the temperature in the room, and therefore the operation of the mechanical thermostat:

on battery

When the air temperature in the heated room changes, the amount of coolant changes. At the same time, the volume of the bellows changes, which activates the control spool. The movement of the spool is directly related to the change in air temperature in the room. When the temperature changes, the sensing element reacts and actuates the regulator valve stem. As a result, the change in stroke regulates the supply of coolant to the heating device.

Installation

The thermostat for a mechanical type battery must be installed on the supply pipeline. In this case, the thermostat head should be positioned horizontally and should not be exposed to direct sunlight or heat. If the valve is covered by a curtain or blocked by furniture, a dead zone is created, in other words, the thermostat is not in contact with the ambient temperature, and for this reason it does not perform its functions effectively.

If another placement of this device is not possible, special sensors with an attached sensitive element are used, designed for remote control.

Electronic thermostats

Electronic heating is an automatic control device that ensures the maintenance of a given temperature in various heating equipment.

In the heating system, it automatically controls the boiler and other actuators (valves, pumps, mixers, etc.). The main purpose of an electronic thermostat is to create a temperature regime in the room that was previously determined by the user.

Principle of operation

The electronic heating temperature regulator is equipped with a temperature sensor, which is installed in a place free from direct influence of heating electrical appliances; it provides the device with information about the thermal state of the room. Based on the data received, the electronic device controls the elements of the heating system.

There are digital and analog thermostats with temperature control. The first ones are most widespread due to their functionality. Electronic thermostats are:

• With closed logic.
• With open logic.

Closed logic is a constant algorithm of operation over time and a rigid internal structure that does not depend on changes in environmental factors. Only certain programmable parameters can be changed.

An open logic thermostat is a freely programmable device, characterized by a wide range of functions and settings, it can be adjusted to any operation and environmental conditions.

Unlike devices with closed logic, these devices are not so widely used. This is justified by the fact that their management requires a certain qualification degree. Therefore, not every ordinary citizen can understand the modes and settings of electronic thermostats. Open logic is widely used in the industrial segment, but over time it can become an integral element of any person’s life.

Installing a thermostat on a battery

During the installation process, it is very important to follow the instructions and not place devices of this type in niches, behind decorative grilles and curtains. If for any reason this is not possible, a remote sensor is installed.

It is ineffective to install a thermostat for cast iron batteries, since they take a very long time to heat up and cool down.

Before proceeding with the installation of thermostats, it is necessary to turn off the riser and drain the coolant from the heating system.

Only after this can you proceed to the installation of this device; it is recommended to perform them in the following sequence:

Settings

The thermostat with temperature control is configured as follows:

• All windows and doors in the room are tightly closed to minimize heat loss.
• In a room where maintaining a certain temperature value is required, it is necessary to install
• The valve opens completely, for which the thermostat head is turned all the way to the left, in this case the radiator will function with maximum heat transfer, and the temperature in the room will begin to rise.
• As soon as the temperature becomes 5-6 °C higher than the original temperature, you need to close the valve; to do this, its head is turned all the way to the right, after which the air in the room will gradually cool down.
• After the temperature reaches the desired value, the valve opens slowly by rotating the regulator head to the left. In this case, you need to listen carefully, as soon as you hear the sound of water and feel the sudden heating of the thermostat body, stop rotating the head and remember its position.
• The setup is completely completed. The room temperature will be maintained with an accuracy of 1 °C.

Thermostats on electric radiators

In the conditions of modern work of utility companies, when during the cold season in apartments the temperature is not always at the level necessary for a comfortable feeling, many are switching to electric heating devices. They can serve as both an additional and a main source of heat.

As a rule, today many manufacturers produce with a thermostat, which allows you to set individual temperatures in each room. Electric radiators are a convenient alternative and an excellent complement to central heating.

You can regulate the rate of flow of coolant into the heating device (battery or radiator) using a valve that is installed in front of it. This can provide not only comfort, but also provide a certain level of protection in an emergency situation in which disconnecting part of the pipeline with the heating radiator is necessary.

For this function, you can consider installing the following shut-off and control valves:

• ball valve;
• cone valve;
• automatic thermostat.

Adjustment using a ball valve is not very effective because it is designed for only two operating modes: open and closed. Intermediate positions of the valve lead to loss of its tightness, since solid particles contained in the coolant can damage the shut-off ball.

A manual cone valve can regulate the temperature much more reliably. It may not be completely covered. The main thing is not to forget to return it to the starting position. In any case, this type of heating temperature adjustment requires constant attention.

It is most convenient to regulate the temperature in the room using automatic thermostats, which are installed in front of the radiators. They are also called thermostats.

Mechanical thermostat design

Each internal temperature value corresponds to a certain pressure value of the working medium in the bellows. This pressure is compensated by a spring that regulates the stroke of the rod.

As the temperature increases, the valve cone will move towards closing until the pressure of the working medium in the bellows is balanced by the spring force. When the temperature decreases, the process will be reversed.

Advantages of modern thermostats

• Modern thermostats have an ergonomic design that fits well into the interior of any room. In addition, they are convenient to regulate the temperature;

• They are quite easy to install in new and existing heating systems, as this equipment is adapted to local temperature conditions. They can be operated without preventive and maintenance throughout their entire service life, which is quite long;
• After equipping heating radiators with thermostats, there is no need to open windows to regulate the temperature in the building;
• The temperature range in which thermostats operate is from 5 °C to 27 °C. The temperature can be set to any value in this range and will be maintained with an accuracy of 1°C;
• Thermostats ensure uniform distribution of coolant throughout the heating system. In this case, even heating devices that are located on the periphery of the circuit will effectively heat the room;
• The thermostat prevents excessive heating of the indoor air if direct sunlight enters the room, or the temperature rises due to other factors (the presence of people or the presence of electrical appliances);
• When using thermostats in autonomous systems, fuel savings of up to 25% are achieved, which has a positive effect on both the cost of heating and the amount of hazardous waste after combustion.

Taking into account the fact that the price of these devices is low, the advantages of their use are quite significant:

• thermal energy is saved;
• there is an improvement in the indoor microclimate;
• simplified installation;
• no operating costs for thermostats.

Important! The use of thermostats is especially effective in individual residential projects - private houses and country cottages. In this case, the installation of thermostats pays for itself within one season.

In conditions of central heating, thermostats provide comfortable regulation of the microclimate in the room.

Important! In an apartment, the installation of thermostats must begin with those rooms where the dynamics of temperature changes is significant: the kitchen, the living room (where the number of people changes significantly), rooms where direct sunlight falls.

General instructions for installing such equipment are as follows. In private homes, thermostats should first be installed on the upper floors. The reason for this is the following: the heated air rises and the temperature difference in the rooms on the lower floors and above fluctuates quite a bit.

From an economic point of view, it is very effective in a private house to install panel radiators with a small capacity with thermostats that quickly respond to the opening and closing of thermostatic valves.

Thermostats are subject to certification and quality products must have a certificate of quality or conformity. There are two types of thermostats on the market now: gas and liquid. The service life of such equipment is about 20 years.

Liquid or gas-filled thermostats

Gas-filled thermostats respond faster to changes in indoor temperature. Liquid thermostats respond more accurately and better to changes in pressure inside the corrugated cylinder and transmit it to the actuator better.

Advantages of gas-filled thermostats

The technical solution, in which the thermostat is filled with gas, has several serious advantages:

• Gas condensation occurs in the coolest part of the device, farthest from the valve body. For this reason, the response will be the fastest, since its operation will not depend on the water temperature;
• This type of thermostat responds well to the dynamics of room temperature. This allows for efficient heat transfer.

conclusions

Thermostats are especially effective when installed in individual heating systems, since in addition to increasing comfort they provide a significant economic effect.

Thermostats can not be installed in all rooms at once, but start with those where the temperature changes the most. In this case, the use of thermostats will give the best results.
