A device that regulates the operating mode of a gas boiler, focusing not on the temperature of the coolant in the boiler, but on the air temperature in the room - this is the temperature regulator for the heating boiler. That is, this is a device that provides not just control of the process of heating water with a gas boiler, but control of the process of heating it based on the final result.

Why should you buy a thermostat?

When the operation of a gas boiler is adjusted manually, the equipment is forced to operate in a mode that involves constant short-term switching on and off. In this case, water heating is started for a short period of time - no more than 10 minutes. At the same time, constant circulation of water in the system is ensured by pumping equipment, which operates regardless of the condition of the heating elements.

Such organization of the climate system operation is fraught with significant consumption of electrical energy. In addition, this mode leads to rapid wear and tear of all heating boiler systems. Therefore, it is not at all surprising that room thermostats have become so popular all over the world. In some Western countries, their installation is considered mandatory. Since if the house is heated using a gas boiler, the presence of a “home controller” significantly reduces gas and electricity costs, and also helps to use expensive equipment more carefully.

The thermostat for the boiler has a certain response threshold (on average about 0.2 °C); when the air temperature decreases or increases relative to the specified parameters, it either turns on or turns off the boiler and pump. Such a system guarantees the owner of the thermostat a number of advantages:

• fully ensures control over maintaining the required temperature in the home, which means that even on days of sudden temperature fluctuations outside, coziness and comfort will always reign in the house where the thermostat is working;
• with the advent of this equipment, the owners of a house or apartment immediately have at least one less problem: not only the “weather in the house,” but also the level of operation and serviceability of the boiler will now be monitored by this small device;
• Due to significant savings in fuel and electricity, the cost of purchasing the device pays off within a few months.

What are thermostats?

Currently, the choice of thermostats is large, and they may vary depending on:

1. Type of control of boiler operating modes:
   • wireless;
   • wired.
2. By level of functionality:
   • simple;
   • provided with a hydrostat function;
   • programmable.

A wireless room thermostat for a gas boiler is capable of regulating the level of operation of the boiler and heating the air in the rooms using a radio signal. For wired ones, only the method of connecting to the controller via wired connections is relevant.

The capabilities of thermostats may vary. Less expensive - simple, reliable and durable wired thermostats do an excellent job with the list of basic functions, stably maintaining the level of set temperatures in the room (usually in the range of 10-30 o C), but only in one mode. In addition, the operation of the device does not affect the level of fuel consumption by the boiler.

A completely different matter is a wireless room programmable thermostat for a gas boiler.

By purchasing such a device, you can use the following features:

• remotely monitor and control the operation of the boiler;
• installation and configuration of various operating modes of heating equipment depending on the day of the week or time of day;
• monitoring fuel consumption and serviceability of gas heating boiler systems.

The list of possibilities is even wider for thermostats equipped with a gyrostat function. Such a room thermostat for a gas boiler is capable of providing control not only over the temperature in the room, but also over the level of air humidity.

Connecting wireless option

The operating principle of a room thermostat for a gas boiler is quite simple, but wireless thermostats remain the most convenient in terms of connection. This model usually consists of a pair of blocks:

• block for installation near a gas boiler (by connecting to a controller or gas valve);
• a unit with a set of control buttons and a display - designed for installation in a room from where it is planned to control the air temperature in a house or apartment.

Moreover, the connection of the thermostat to the boiler is carried out using terminals, and the transfer of information from one unit to another is carried out using a radio channel. Perhaps the only disadvantage of cordless models is their dependence on rechargeable batteries, which often need to be recharged or replaced. At the same time, the device itself informs the owner about the battery charge level, which is certainly a plus.

Where to put the wires

The situation is much more serious when installing wired models. And although Experts recommend combining this procedure with repair work, since the wiring will most likely have to be either masked or laid in the body of the wall in the formed channel after it is grooved.

Another disadvantage of wired thermostats is the need to allocate a separate room or significant space in the house for placing the device. Since, according to the instructions, the correctness of their operation may depend on the availability of sufficient free space.

It is also extremely undesirable to install it near household, external climate control equipment and heating devices, as well as in places where the device will be exposed to direct sunlight.

The process of connecting a thermostat is, in principle, not difficult. It is enough to follow the instructions drawn up by the manufacturer of the boiler and thermostat.

About the mechanical thermostat

An important point, those who have chosen a more durable and reliable mechanical thermostat for their home should remember that this device does not require an electrical connection or batteries. However, during the work on connecting it, it will also not be possible to avoid fiddling with the wires. But in this case we are talking about wires that ensure communication between the device and controlled climate control equipment.

The mechanical thermostat is connected to the boiler using a 2-wire connection.

The video shows how to connect the Ballu BMT-1 thermostat.

About the specifics of the settings

After you have successfully connected the new equipment, you need to configure it, during which you can set the desired parameters, including the ability to:

• Heating, and in some cases air conditioning in the room;
• Determining the optimal delay period for the activation of the thermostat sensors (a window open for a short time or, on the contrary, the heat flow from a switched-on hair dryer can “mislead” the sensors of the device, but enabling the response delay function will avoid errors;
• Setting the temperature fluctuation step. That is, choosing a step of 1 degree means that the thermostat will turn the boiler on or off when the air temperature changes by 1 o C.
• Determination of maximum comfortable temperatures. Some devices allow you to program the temperature depending on the time of day or day of the week (for example, on weekdays, when no one is home, you can reduce the air temperature by several degrees, ensuring fuel savings; a couple of hours before the inhabitants of the house return, the device will turn on itself , will adjust the temperature, ensuring it increases to a comfortable level).

About compatibility issues

The method of connecting the thermostat to the boiler is largely determined by the choice of thermostat model and can be done either from a controller, from a battery, or from a network.

You can often find recommendations from boiler manufacturers; when purchasing a simple or programmable thermostat for a gas boiler, rely on the boiler manufacturer and its recommendations. In principle, this advice is worth listening to, although, having looked through the pages of numerous forums where issues of connecting climate control equipment are discussed, you can often come across the opinion that for the most part, products from different brands “get along” well without entering into conflict.

But the parameter that is really worth considering when deciding to buy a temperature sensor for a heating boiler in a regular HVAC or household appliances store or online store is the area of ​​the room heated by the boiler and the most preferred temperature regime.

TOP thermostats 2017–2018

Having studied the opinions of consumers and analyzed information from several authoritative online publications that annually compile rating lists of the most discussed models of climate control equipment, it is easy to conclude about the popularity of thermostats of such brands as:

Bosch

At the same time, the company believes that the best thermostat for a Bosch gas boiler is, of course, Bosch. And, although there is so much information on the Internet about the successful symbiosis of climate control equipment from this manufacturer with thermostats from other companies. However, for example, the Bosch software digital thermostat definitely deserves attention. The model is equipped with a digital display, has a calibrated temperature sensor, and has backup power options. The device can regulate the room temperature according to the time of day and days of the week.

The video describes in detail the Bosch EMS series regulators.

Ariston

Also, when choosing a room thermostat for an Ariston gas boiler, you should pay attention to the thermostats offered by this Italian company. Among them you can also find models that can program the required temperature conditions not only for the week ahead, but also for any hour of the coming week. There are also less complex, but cheaper options that “can” set the desired temperature regime for the next 24 hours. However, the availability of hourly programming helps home owners solve many problems, including saving gas and electricity.

We invite owners of Ariston boilers to take a closer look at the Sensys control panel.

Advantages:

• full system control via bridgenet® protocol;
• easy setup/management of system parameters;
• temperature control;
• display of solar system parameters (if connected);
• display of energy audit report (kW), solar system performance, reduction of CO2 emissions, hot water reserve;
• electronic room temperature sensor;
• easy-to-manage daily and weekly heating mode programming;
• easy-to-manage daily and weekly programming of the DHW mode (if an external boiler is connected to a single-circuit boiler).

Protherm

This company also recommends connecting the thermostat to the Proterm gas boiler only when using “native” models. There are a number of reasons for this. For example, thanks to a special eBus switching bus, the thermostat can control the modulation of the gas burner. Thermostats from other manufacturers cannot be connected to the Proterm boiler in this way. In addition, on the display of some models from Protherm you can see not only the specified boiler operating modes, but also error codes that occur. In addition, the system, if necessary, is capable of restarting the boiler itself. This way the boiler temperature is regulated.

Buderus

Connecting a room thermostat to a Buderus gas boiler will also create fewer problems if we are talking about a device manufactured by the same company. Moreover, the developers have provided a simple and intuitive interface for the device.

Programmable room thermostat Simple MMI 7 Days – with communication via OpenTherm™ protocol. Designed for complete boiler control and comfortable room temperature control

RQ

If you managed to purchase a room thermostat rq10, connecting to a boiler of the same brand will not be difficult. Moreover, the quality of this technology rarely raises any complaints.

Ferroli

Room thermostat for Ferroli gas boiler – a very successful development of the Italian company.

Baxi

Also on trend is the thermostat for the Baxi gas boiler, which is easy to install and operate, also features an intuitive adjustment system and provides significant savings to home owners.

The BAXI mechanical room thermostat is used to detect the room temperature and transmit data to the boiler, providing feedback. Regulates room temperature from 8°C to 30°C

conclusions

Thermostats from the listed companies successfully help solve problems such as:

• problem of timing of the gas boiler and pump (unreasonably frequent switching on and off of devices);
• setting the optimal temperature regime by day and hour;
• simplification of the heating device maintenance process;
• setting fine settings.

All these functions will provide comfort in any home and a good mood for its inhabitants.

When the house has a heating system using a gas boiler, the optimal room temperature has to be adjusted manually. Moreover, this heating option is very sensitive to weather changes. As soon as it gets colder outside, you have to increase the temperature of the coolant. Even expensive models with a high level of automation require these actions. To save consumers from such work, manufacturers have released a thermostat for the heating boiler (temperature regulator).

Smart Device Options

Thermostat for a heating boiler (temperature regulator): how it works

The installed heating system heats the room to the set temperature, regardless of the level of heat or cold inside. At the same time, a person feels well the daily weather changes if he does not change the mode manually.

To eliminate this problem in a small house without a second floor, it is enough to install one thermostat in the passage room.

Note! It is necessary to correctly connect and install the device so that it works correctly and sends a signal to the boiler.

The design of a simple device includes a highly sensitive element (actuator) and a contact group with the regulator. In appearance, it is a closed bellows, inside of which there is usually a gas mixture, sometimes a liquid. This filler reacts to changes in temperature and moves the rod to close the contacts when the temperature rises, and when the temperature drops, the opposite occurs.

The thermostat performs the task of turning the heating system on and off when the set temperature is reached autonomously, without human intervention. A simple circuit includes two contacts, the wires of which are routed to the boiler and connected to the valve.

When the device is turned on, the last element is in the open state. When a short circuit occurs, the fuel supply to the burner is cut off and the flame stops. In the reverse process, fire occurs from the igniter.

Types of home temperature sensors for heating boilers

Thermostats for heating boilers (temperature controllers) come in several varieties:

• Wired. The key to correct operation is the correct installation of conductors. This is necessary for uninterrupted communication of the equipment with the boiler.

• Wireless. Using a radio signal, information about changes in temperature in the apartment is provided. The device consists of two blocks, one of whichmounted in the room, the other on the boiler itself. The controller unit has a liquid crystal display and a keyboard.

We will analyze each option in more detail, with approximate costs and an overview of several models.

Mechanical (wired) thermostat

A mechanical thermostat for a heating boiler has its own characteristics; the price of the models varies as well as the characteristics. Such a device must be pre-set to achieve the optimal room temperature. This is a complex process, so it is better to contact a specialist.

Each model includes two parts: a thermal head and a valve. The operation of the device is influenced by:

• frequent ventilation;
• bright sunlight coming through the windows;
• sudden change in weather.

Installation must be done only in a horizontal position, and you must choose a place where there are no objects blocking the device or direct sunlight. Modern models have small dimensions that can be installed in a small niche.

The installation itself will not take much time. If you turn off the heating, then you need to turn the thermostat knob. This will protect the device from the formation of sediment.

Here is an example of two popular mechanical thermostat models:

Review by Mikhail, Balabanovo:“I purchased it two years ago and installed it myself, not far from the boiler. It works properly, the house is always warm.”

Review by Dmitry, Tver:“I heard a lot of good reviews, I bought it a month ago. There were no problems with installation and configuration. So far everything is fine."

Mechanical room thermostats for gas boilers are popular, have a low cost and can be installed independently.

Important! Correctly configure the mechanical device before use, otherwise there will be no result. It's better to call a specialist.

Remote equipment options

The thermostat for the heating boiler (temperature regulator) can operate remotely.

There are several types of such devices:

• simple;
• program rooms.

The first option was created to maintain a given room temperature. And when installing the second option, the owner of the premises receives the following advantages:

• remote control;
• you can set the mode depending on the time of day;
• speed of regime change;
• you can schedule changes for a week;
• quick response of the boiler to changes;
• low fuel consumption;
• battery is being used.

Remote program temperature sensors (room) for gas boilers are created for people who love the maximum level of comfort and new equipment. Here are some popular options for such a device:

Model name	Specifications		Price in rub.
Bosch TRZ 12-2	Device type	Electronic	9800
	Installation type	Overhead
	Temperature	+5 to +39 ⁰С
	Block Dimensions	91*113*33 mm
	Timer	Weekly

Review by Denis, Moscow:“I also have a Bosch gas boiler, so I bought this thermostat. It works for six months without problems, it supports weekly planning properly.”

Review from Ekaterina, Bryansk:“I struggled with manually adjusting the boiler for a long time. Then I installed a Siemens REV13 (hired a specialist). I’ve been managing the temperature simply and quickly for a year now.”

Software temperature sensors for heating boilers vary in cost and functions. At the same time, all models do an excellent job of controlling the temperature in the room, and the ease of adjustment allows you to add heat to the house without getting out of bed.

Automation is used for ease of management and economical consumption of energy resources. To properly use a thermostat for (temperature regulator), you need to study modern engineering solutions. An overview of the current market situation will be useful. It is also necessary to evaluate the possibility of performing installation operations yourself, without resorting to expensive professional services.

Why do you need a thermostat for a heating boiler (temperature regulator) in rooms?

When developing new heating equipment, much attention is paid to the efficient use of energy resources:

• are created in such a way that the formation of useful infrared radiation occurs with maximum efficiency.
• Gas boilers are equipped with continuous flame control systems that optimize the combustion process.
• When used, they create chambers of complex shape along the path of combustion products exit. Here the temperature increases further.

But the rational use of electricity and fuel will be useless if the optimal consumption of the generated heat is not ensured. To solve this problem, certain parameters of individual components are required.

To fulfill the last condition, you will need a heating boiler (temperature regulator). When used correctly, this technique can provide you with the following benefits:

• Maintaining the set temperature automatically, without the need for careful control.
• Saving energy resources (money) up to 30% and more.
• Possibility of remote control, quick transition to special modes.
• Extending the service life of boilers through careful operation.

For your information! Optimizing equipment operation using a temperature sensor for a heating boiler will extend battery life when the mains power is turned off. The equipment will operate for a long time using the built-in battery, which will increase the time for calling specialists and eliminating the emergency situation.

Functions of a temperature sensor for a heating boiler: adjusting the coolant temperature

A modern boiler control system consists of several parts:

• In this embodiment, temperature sensors in the rooms and outside air are directly connected to it.
• Power is provided by the network adapter. Built-in batteries ensure continued operation when 220V is turned off.
• A GSM unit is installed here for remote control. With its help, the user will receive operational data on indoor temperature. If desired, it turns on the desired mode by sending a control signal from a smartphone or tablet. These functions are performed under the control of specialized software.
• Commands to the boiler are received via a wired connection. They include heating and pump. This is more economical compared to the built-in thermostat discussed above. The air temperature decreases more slowly than the coolant, so the burner ignition frequency decreases. In such conditions, the service life of the equipment is extended.

Important! In boilers compatible with room thermostats, the control board must have special “Room Thermostat” input sockets. The corresponding capabilities are indicated in the official instructions of the manufacturer.

The algorithm for operating such equipment as a whole deserves high marks. If the sun comes out, the temperature outside rises, the boiler will not turn on. It became colder in the room after ventilation - there is no need to reconfigure the heating equipment and then set the regulators to the normal position. The necessary actions will be performed automatically. In just one season you can recoup your investment. But in any case, a more thorough study of the parameters of the equipment and models presented on the market will be useful.

To choose the right equipment, you need to consider the need to use outdoor temperature sensors. In some models they are connected directly to the standard electronic control board. With their help, the parameters of inertial processes are optimized.

So, if the user has set an excessively high temperature, and it gets warmer outside, they will continue heating even when the thermostat turns off the boiler. If there are sensors outside the room, the required command will be given faster. The actual savings in the process of their active use are small. Therefore, these enhanced capabilities are assessed in conjunction with a certain increase in cost.

Types of technology and selection criteria

For heating boilers (temperature controllers) they are equipped with various hardware and software units. Additional functionality and technical features of modern models are listed below:

• Sensitivity of temperature adjustment in steps of 0.2-0.3°C.
• Setting individual time schedules for each day of the week.
• Quickly select a standard program and create algorithms taking into account personal preferences.
• The use of safe ones, in which the formation of sparks during switching is excluded.
• Maintains performance over a wide range of temperatures and.

Some important details are shown in the pictures.

How to connect a thermostat to a boiler

It is more convenient to work with temperature controllers for heating boilers that support a wireless connection. For example, the installation algorithm for Salus/Controls iT500 is given:

• The controller unit of such a device can be placed in any room at a distance of up to 30-50 meters from the receiver. It is advisable to prevent unwanted external influences on the thermostat. It is fixed on interior walls, away from, not in direct sunlight. But installation in niches and other places where the natural circulation of air flow is difficult is not recommended.
• The distance will be shorter if there are thick reinforced concrete walls or other obstacles to the propagation of radio waves on the corresponding line. Signals are transmitted at a carrier frequency of 868 MHz.
• If several sets are installed at a facility, you can change the coding. A DIP switch is used for this. Let's choose from 32 options. The distance between the receiving units is maintained at more than 90 cm to eliminate false positives.
• The Salus/Controls iT500 model is designed in a safe design, which allows for use near gas equipment.

The previous operations are performed with the 220 V power supply turned off.

General conclusion

The use of a wireless thermostat for a gas boiler simplifies the operation of heating equipment. The simplest models are inexpensive. But their installation involves laying wire communications. Therefore, total costs may increase significantly compared to the preliminary plan. More complex sets use radio frequency to transmit control and control signals. Installing such products is not difficult to do yourself. Their high cost is due to their advanced functionality.

To control the boiler and the entire heating system, special elements are provided that reduce energy costs for heating, and also help create an optimal temperature regime and at the same time prevent overheating of the room. These elements include a thermostat for a heating boiler. The temperature regulator allows you to save up to 20% of fuel resources, and by what means, we will tell you in this review.

A high-quality thermostat significantly reduces the cost of fuel raw materials

Thermostat for a heating boiler: temperature regulator or more?

There are several types of boilers. These are gas, solid fuel, and electric models. The material used to manufacture such equipment is cast iron or steel. Temperature control and adjustment is carried out using a special thermoelement. This equipment is a metal structure. As a result of thermal expansion, the position of the lever that moves the damper changes. To allow the combustion to grow, the damper is opened slightly. Newer designs include controllers that can regulate air flow.

The most commonly used gas models are single-circuit and double-circuit. Some models have separate room thermostats for a circuit with hot water supply and a heating circuit.

Electrical devices are characterized by high efficiency and simple connections. In such designs there is protection against overheating and temperature control. Using a mechanical timer, various methods of temperature control are made. More often, the unit simply turns on/off when the temperature drops/exceeds. But it is also possible to set a specific switching time.

Helpful information! Mechanical devices have a round dial. To set the on time you need to turn the dial. Such devices are easy to adjust.

Types of control devices

Thermostats for heating boilers with the option of temperature control are divided into several types:

• mechanical models with one function;
• programmable models with a large range of auxiliary settings.

Also, similar designs are wireless and wired. are installed in the selected location, a temperature sensor is connected and connected to the control device.

Note! Thermostats must be provided with constant air access to prevent overheating. It is also not recommended to install electrical appliances nearby.

Selecting a room programmable device

The option of an electronic temperature sensor for a heating boiler helps you select the appropriate temperature mode and change it at your discretion. The room thermostat sets the set values ​​every day. Some setpoint values ​​can be programmed, for example when day turns to night.

Such controllers have additional options. For example, a function that allows you to stop heating for a while and then resume it. You can also change the programmable temperatures for the duration of the configured periods. Another useful option is the ability to change the heating intensity.

Thermostat as a central element

The central thermostat for the heating boiler (temperature regulator) is located at a certain distance from the heating unit and allows you to turn off and turn on equipment throughout the house.

Models from previous years are connected directly to the heating unit by wires, while more modern designs are distinguished by remote control. The latest devices are mounted in dual-circuit units Beretta, Ferroli and AOGV. Room control mechanisms for Protherm and Gsm brand boilers are popular. They differ in their dilatometric mechanism.

Room devices stop heating when necessary. They monitor the air temperature and turn on the heating when the temperature drops. The best place for a microcontroller is considered to be the bedroom and living room.

Installing a controller will allow you to obtain accurate data on the room microclimate

Helpful information! The recommended temperature for the thermostat is 20 degrees, and in the children's room - 21-22 degrees. At night, the temperature can vary from 19 to 21 degrees.

Thermostatic valves for regulation

Such a device allows you to create a certain coolant temperature by mixing the forward and return flows. The device helps control temperature values ​​by changing the flow of hot water through the battery. In this case, the mechanism controls the supply of hot water through the battery, but not through the boiler. It is installed in any room where you need to maintain a certain temperature.

Selecting a temperature sensor for a heating boiler

When choosing a room temperature sensor for a gas boiler, it is worth considering that they are divided into two types. These are wireless models that transmit information using a transmitter mechanism and a device for receiving radio waves. And also wired ones, which transmit data to the controller through wires.

According to the method of location, temperature sensors are:

• waybills that are mounted on the highway;
• submersible, which come into contact with liquid;
• indoor devices are placed indoors;
• external ones are mounted outside.

For a standard heating system, one room sensor is used, and for a beam-type collector system, several sensors can be used.

How to connect a thermostat to a boiler

To choose a high-quality model of a mechanical thermostat for a heating boiler, you also need to know the prices. The cost of individual models can be seen in the table.

Image	Models	Cost, rub.
	Viessmann 7817531	3670
	TR 12 for boilers Bosh Gaz 6000 W for gas boilers	2100
	Galan Comfort	3500

	Terneo rk 30 for electric boilers	2870
	BeeRT regulator for electric boilers	3300
	Thermostat for solid fuel boiler Auraton S 14	5990

The following recommendations will help in installing such devices:

• it is desirable that the control device and the heating unit are made in the same factory, which will facilitate the installation process;
• Before purchasing, calculate the area of ​​the heated room and the optimal temperature, which will allow you to avoid equipment downtime;
• Before installation, consider the thermal insulation of the room. this will prevent significant heat loss.

Connecting a mechanical regulator to a heating unit

Experts advise installing regulators in living rooms. If they are placed in utility rooms, this will lead to problems in the system. It is also better to choose a colder room. There should be no heat sources or electrical devices near such equipment.

The boiler is turned on using a relay. Modern gas boilers have a special place for connecting the thermostat. You can connect the device using the terminal located on the boiler. The connection method is indicated in the boiler passport.

After installation, the equipment needs to be configured. On the front panel there are buttons that are used to configure the device. Switches allow you to control air cooling and heating, as well as temperature fluctuations and sensor delay times.

Using the buttons, the optimal temperature is maintained during the daytime. And at night this indicator will decrease in order to ensure savings in fuel resources and prevent their overconsumption.

The thermostat is an important part of an autonomous heating system. It ensures high-quality operation of the system and also avoids unnecessary waste of fuel. This device, despite its simplicity, ensures long-lasting operation of the boiler and the entire system.

Many owners of private houses install an autonomous heating system in their homes, which effectively creates a comfortable atmosphere in the rooms of the home. Any such system has the ability to adjust the temperature level. This is ensured thanks to the thermostat for the boiler. It is thanks to this that the owner can change the temperature to create a favorable climate in the home and the opportunity to reduce energy costs when operating the boiler.

Thermostat purpose and characteristics

The operation of this device is based on the principle of turning the heating boiler on and off. Before this, a temperature sensor is installed in the device. This device is easy to operate and yet demonstrates sufficient reliability for controlling the temperature in the rooms of the house.

The main advantage of using a thermostat as part of a heating system is the ability to reduce energy costs.

It does not matter whether the installation runs on gas or is powered by electricity. According to such a parameter as functional purpose, all thermostats are divided into two types:

• manual;
• programmable.

Which thermostats are better?

Hand-held instruments are equipped on/off button. In addition, the thermostat has a dial for adjusting the required temperature level, which is rotated manually.

Programmable thermostats have more complex device. However, this does not mean that their use is problematic. Complex designs provide more options that become available to the owner using a heating system with a built-in thermostat.

One of these is turning the boiler on and off automatically at certain time intervals that are configured by the user.

Classification of thermostats

For reliable operation of wired thermostats, special attention must be paid to the high-quality installation of conductors.

This must be done to ensure their uninterrupted connection with the boiler. The signal received by the thermostat starts the process of supplying coolant to the heating circuit.

According to their design, thermostats are divided into the following types: wireless and wired.

In wireless devices, the operation process is regulated through the use of a radio signal, which goes to the temperature sensor.

Typically, the thermostat for heating boilers contains two blocks. One of them is installed in close proximity to the boiler; it is connected by its terminals.

The other one is installed in a heated room. These two blocks communicate with each other via a dedicated radio channel. The main difference between the main block and the executive block is the presence LCD display and keyboard.

Automation classification

Based on the criterion of automation level, thermostats are divided into the following groups:

• Analog.
• Digital.

The characteristic features of analog devices are that they are controlled manually, for which they use mechanical regulator, which is directly connected to the rheostat.

Through microcircuit signals the digital device is controlled. The use of equipment of this type allows the use of a large number of temperature conditions when operating the heating system.

Classification by sensor type

Depending on the sensor installed in the thermostat, models of these devices are divided into those with mechanical and electronic sensors.

Devices that are equipped with mechanical sensors are available on the market capillary thermostats. They calculate the temperature by the change in the total volume of the heated liquid in a sealed flask. Such a sensor is immersed in a heat exchanger located in a heating device.

The main positive characteristic is precision and durability. As for the disadvantages, the main one can be considered incompatibility with programmable controllers.

If an electronic sensor is installed in the thermostat, then when the controller operates it will read signals from the thermistor. The thermistor itself measures resistance under the influence of temperature.

Advantages of the device

It should be noted that if a programmable thermostat designed for a gas-fired boiler is installed in the heating system of a private house, then it has the following advantages over simple-type devices:

When choosing any device for a boiler, you first need to consider the requirements for its functionality.

If the serious functionality of the device is not important to you, then you can install a simple device in the heating system. In most cases, owners purchase programmable thermostat due to its good functionality.

How does a thermostat work?

The operating principle of the device from different manufacturers does not have any significant differences. They may even look the same. The difference is only in minor details. In terms of functionality, they are practically no different from each other.

During operation of the device, coolant heating control and ambient air, for which a sensor is used, which can be built-in or external. The controller sends a signal to turn it off and on to the automatic unit installed on the heating boiler.

A shutdown signal is received if the temperature of the coolant or ambient air rises above the set value. When it falls below a given level, then a signal to turn on is given heating equipment.

Features of installation work

If the owner decides to install a thermostat in the heating system, then this work can be done with your own hands. It is advisable to install the device in the coldest part of the house or where people living in the house are most often located.

Typically, this device is installed in a place that is convenient for use and where easy access to it is provided.

Before installing the thermostat for the boiler, you should choose a location that has access to constant air flow. This is necessary to ensure its correct operation.

Therefore, installation of such products should be carried out away from other electrical appliances, since during operation they can increase the air temperature and thereby affect the operation of the thermostat.

Conditions for installation

When installing a thermostat for a boiler, the following conditions must be met:

There are several methods that can be used to connect a thermostat. In order to avoid errors during installation, it is necessary read the instructions to heating equipment. In this case, reliable communication between the thermostat and the heat exchanger valve can be ensured.

To ensure this you need to connect the device to the electrical circuit. Models of electric boilers usually have a built-in thermostat, which is located in the equipment housing. This is due to the fact that quite often these installations are used for the installation of “warm” floor heating systems.

The boiler thermostat is an important device that provides temperature regulation and thus allows the owner to create a favorable microclimate in his home, and also provides an opportunity to save energy resources.

The boiler thermostat can be installed in any heating system. With its help, you can, if necessary, change the temperature regime in the room, thus creating a comfortable atmosphere, and in addition save energy resources.
