When heating a house with a gas boiler, the issue of reducing the cost of electricity and fuel, increasing or extending the life of the equipment, and maintaining a comfortable temperature is always relevant. The thermostat for a gas boiler allows you to control the operation of the heating device, providing comfort in your home.

Room thermostat for gas boiler

Types of thermostats

Devices for controlling the operating modes of boilers are divided into two main types:

• wired - the regulator is connected to the controller via a wired connection;
• wireless - regulate the process of heating a house from a radio signal.

Functionally room thermostats for heating are:

• simple;
• programmable;
• with hydrostatic function.

Simple devices can only maintain a stable set temperature in the room, do not have a direct effect on reducing gas consumption.

Programmers have a number of functions:

• remote control of boiler operation parameters;
• installation and configuration of day and night modes of equipment operation;
• programming of the heating system by day of the week;
• significant reduction in fuel consumption.

The hydrostat function allows you to control the humidity in the premises, reduce or increase it, depending on the preferences and desires of the owner.

Wired devices are distinguished by reliability and simplicity of design, low cost, and long service life. A thermostat for a heating boiler of this type is capable of maintaining only one temperature regime, which is set by changing the position of the handle located on the front side. On most devices, the range of possible temperatures is 10-30°C.

Depending on the brand, the room thermostat can be connected to the power supply from the mains, directly from the boiler controller or from a battery.

The main disadvantage of this type of device is that it is possible to set only one temperature value. To change it, you must reset the handle to a different position. In addition, cable laying causes certain inconveniences, therefore it is better to install a wired thermostat to a gas boiler during finishing work and installation of the heating system.

If the heating system is already installed, it is more convenient to install a wireless programmable thermostat for a gas boiler, during installation of which the aesthetics of the interior will not be violated.

The wireless thermostat for gas boilers consists of two blocks. One of them is placed at the heater and connected to the gas valve or controller using terminals. Another is installed in the room from which it is planned to control the operation of boiler equipment.

Communication between blocks is carried out by radio channel. The control unit is equipped with a miniature keyboard and a small LCD display for ease of use.

The wireless temperature controller for a heating boiler is installed simply and quickly, does not require any significant costs for the purchase of fasteners.

A significant disadvantage of devices of this type is the limited life of the batteries, which must be changed periodically. When the device is disconnected from the power supply, the sensors will stop transmitting a signal to the heating boiler, which will focus only on the readings of its meters and overheat the coolant.

All modern battery-powered thermostats for heating boilers have a battery warning function.

The room thermostat for a gas boiler allows you to fully automate the heating control process.

Purpose and principle of operation

Gas boilers operate cyclically. When installing automation, gas supply and burner activation occur only if the coolant temperature drops to the value set by the consumer. If the sensors are missing or defective, it is necessary to manually adjust the heating system, changing its parameters in one direction or another throughout the entire cold period. But even with daily manual adjustment, the stability of the temperature regime in the premises of the house cannot be guaranteed.

A room thermostat for a heating boiler is used to set and maintain a user-defined mode.

The thermostat works according to the following principle. The air temperature sensor allows you to set the thermostat in such a way that the gas heater turns on only when the temperature goes below or above the set temperature limit and only for the required period of time. If for the boiler the main parameter is the temperature of the coolant, then for the thermostat it is the air temperature in the room in which it is installed.

By setting the minimum comfortable temperature for yourself, you can no longer worry about controlling the operation of the boiler. As soon as the air temperature drops below the set limit, the remote thermostat for the gas boiler will automatically start the heater and the pump. The same principle of operation is implemented when the air temperature in the room rises - the boiler automatically turns off.

Device selection

The thermostat is not the most expensive thing, but not cheap either. On the modern market there are a large number of brands of these devices from various manufacturers, so you can choose the required device, both in terms of characteristics and functionality, and in terms of cost.

If the main criterion for you is the cost, then it is better to stay on the wired electronic version. Such devices are technologically advanced, have a good response, and their reliability does not depend on oxidizing terminals, which is often the fault of a mechanical room thermostat.

If, when choosing, saving energy resources is crucial for you, and with them in the near future, your own funds, then you should purchase a programmable device. Such a thermostat, which turns on and off strictly at the hours set by the owner, lowers the temperature in the rooms when no one is at home, and can significantly reduce heating costs. Programmable devices, as a rule, have several weekly and daily modes.

Programmers make it possible to simplify and optimize the operation of the heating system as much as possible, therefore it is necessary to carefully look not only at them, but also at boilers for non-volatile heat supply.

If the repair in the house has already been done, and there is no desire to ditch the walls under the channels for wires, the choice in favor of a wireless thermostat with an air temperature sensor is obvious.

When buying, be sure to consult a specialist and independently read the reviews on certain models of devices.

Many boiler manufacturers also recommend buying a thermostat of their own brand, explaining that installation and installation of the device in this case will be much faster and easier, and control over heating equipment will be more reliable. For example, for a Baxi gas boiler, you must also purchase a thermostat of the same brand. In practice, various devices do not conflict with each other in any way and there are no problems with their mutual connection and subsequent operation.

When choosing a thermostat, it is necessary to take into account the area of ​​\u200b\u200bthe room in which it will be installed, and the range of desired temperatures is no less important.

The price of the simplest devices is about $40. Despite the fact that the cost of devices is quite high, we must not forget about the cost savings due to the reduction in gas consumption - the thermostat will pay for itself in a short time.

The first and probably the most important advice is that before connecting the wired thermostat, you cannot start repair work in the room, otherwise, the interior decoration can be hopelessly damaged. The fact is that most often the laying of wires is carried out in the thickness of the walls, for which special grooves are created in them - strobes, and with an already completed repair, chasing can be quite a serious and unpleasant problem.

The installation of the thermostat must be carried out taking into account the fact that for the correct operation of the device, it is necessary to have free space around it. Before connecting a room thermostat, you should make sure that there are no obstacles or obstacles nearby that impede free access to it. Placement of the device is recommended in places where there is no furniture or other bulky interior items, as well as various decorations - carpets, furniture, decorative household items.

Connecting a room thermostat to a wired gas boiler and installing it in a room is not at all difficult. The most important thing is to follow the manufacturer's recommendations exactly and not deviate from the instructions and diagrams that came with the device. The method of connecting the cable in this case depends on the brand and type of thermostat.

The coldest living area in the house or a room in which households often gather is best suited for installing the appliance. Do not install the thermostat near household appliances and heating devices, as well as in places where there is a high probability of exposure to direct sunlight on the device.

When operating a thermostat, you should follow a few simple rules to reduce heating costs:

• when leaving the room for a long time, reduce the temperature of the thermostat to a minimum;
• at night, set the temperature 3-4 degrees lower than during the day, and when you wake up, raise the temperature and warm the rooms. Room temperature control is much easier if you buy a programmable thermostat;
• the device must be constantly maintained in working condition, without waiting for the shutdown, the batteries should be changed in advance.

Conclusion on the topic

The use of room temperature controllers allows you to create the most comfortable conditions for staying in the premises and operating heating equipment, and significantly save money by reducing gas consumption. The temperature sensor installed in the room is sensitive to all changes, increasing or decreasing the heat supply, giving a signal to the heater controller.

However, you should be aware that fuel savings are possible only after the implementation of measures aimed at reducing heat loss at home. Otherwise, the flow rate may increase, since the thermostat will not be able to stop the boiler until the air temperature set by the owner is reached.

Efficient heating control is a vital part of the efficient operation of the boiler and home heating system. Proper use of the controls will reduce the energy consumption of the unit, while creating a comfortable temperature in every room of the house, avoiding overheating of the premises. And the thermostat (or programmer) controls the operation of the boiler, depending on the temperature in the room.

Up to 20% of the volume of consumed energy carriers can be saved using this kind of automation. And energy prices are quite high and the desire of every normal person to reduce their costs.

We consider the situation when the boiler is calculated correctly, the necessary insulation of the premises has been completed, and the heating system is functioning normally.

Main types of boilers and temperature control

There are several types of boilers: solid fuel, gas, electric and liquid fuel.

Boilers are widely used all over the world. There are domestic samples, there are boilers and imported ones. The material of manufacture is steel or cast iron. Easy to operate, economical, with the function of adjusting the temperature of the coolant. In cheaper models, this function is implemented using a special device - a thermocouple.

Structurally, a thermoelement is a metal product, the geometric dimensions of which, under the influence of temperatures, decrease or increase (depending on the degree of heating). And this, in turn, changes the position of a special lever that closes and opens the draft damper. The photo shows an example of such a regulator:

The more the damper is open, the stronger the combustion process, and vice versa. Thus, the volume of air that enters the closed-type combustion chamber is fully controlled by the thermostat, and if necessary, its supply is stopped and the combustion process dies out. In more modern models, controllers are installed that, depending on the specified thermal conditions, control the air flow, turning on (or turning off) a special fan (see photo below):

Gas boilers are the most common and cheapest units to operate. Boilers are single-circuit and double-circuit. Single-circuit boilers have one heat exchanger and are intended only for heating. The switching circuit is shown in the figure below:

Double-circuit boilers have two heat exchangers and are designed for heating and hot water production. The boiler connection diagram is shown below:

Some boilers have separate controls for heating and hot water temperature.

Electric boilers

A fairly common alternative to gas and solid fuel boilers. A lot of advantages, high efficiency, but a long payback period. The connection is simple, like with gas boilers, but without a cold water supply. Temperature control and overheating protection are provided.

Using a simple mechanical electric boiler timer There are three options for starting the central heating system:

1. The boiler is off;
2. The boiler supplies hot water;
3. The boiler turns on and off at the set time.

Mechanical timers usually have a large round dial with a 24-hour scale in the center. By turning the dial, you can set the desired time and then leave it at that position. The boiler will turn on at the right time. The outer part consists of a set of tabs with a 15-minute period, which are inserted for the convenience of adjusting the operation and setting modes. An emergency reconfiguration is possible, which is performed when the boiler is connected to the network.

Mechanical timers are easy to set, but the boiler always turns on and off at the same time every day, and this may not satisfy the owners if the family is large and bath procedures are performed several times a day at different times.

Types of thermostats

According to the type of functions, they can be divided into several groups:

- with one function (temperature maintenance);

- with a large number of functions (programmable).

By design, thermostats are divided into types: wireless and with wires for communication with the boiler. Install the thermostats in a convenient place, connect the temperature sensor, connect it to the boiler control system and use it.

Room thermostats need a constant supply of air to function properly, so they should not be covered by curtains or blocked by furniture. Appliances adjacent to the electric thermostat may interfere with the correct operation of the device: lamps, televisions, heaters located nearby.

The programmable electronic room thermostat allows you to select the desired and comfortable temperature at any time, it is easy to reconfigure and change the operating mode. The timer allows you to set a different heating pattern for weekdays and weekends. Some timers allow you to set different settings for each day of the week, which can be useful for people who work part-time or in shifts. Many Terneo and KChM models are equipped with such thermostats.

A programmable room thermostat allows you to set individual heating standards for each day in accordance with your lifestyle and maintain the temperature at home all the time, regardless of the presence or departure of the owners.
Video: Connecting a room thermostat to a gas boiler

If a boiler with a radiator is responsible for the heating system, as a rule, only one programmable room thermostat is needed to control the entire house. Some patterns need to be adjusted in the spring and fall when the clocks have gone back and forth or there has been a certain change in climatic conditions. We also recommend changing the temperature settings when changing day and night.

Such a climate controller has several options that expand its capabilities:

• "Party", which stops heating for several hours, then resumes;
• "Override" allows you to temporarily change the programmed temperatures during one of the configured periods;
• "Holiday", increases the intensity of heating or reduces it for a certain number of days.

Central thermostat

Such a thermostat is located far from your boiler and usually allows you to turn the heating on or off throughout the house. Older versions are wired to the boiler, newer systems tend to send signals to the device's command post. It is with devices of a new type that quite expensive, but effective devices are equipped: double-circuit boilers Ferroli, Beretta and domestic AOGV.

The most famous are room thermostats for a double-circuit boiler of the Gsm and Protherm trademark. They have a built-in dilatometric thermostat for the boiler, which, depending on the model, can work remotely, often this technology is used for an electric boiler or solid fuel units.

The room thermostat turns off the heating of the system as needed. It works by measuring the air temperature and turning the heating on when the air temperature drops below the thermostat setting and turning it off when the set temperature is reached.

Tips:

1. It is recommended to set the thermostat at 20°C;
2. At night, the set temperature should be between 19-21 ° C.
3. It is desirable that in the children's room it was about 22 ° C.
4. The temperature should not fall below 22°C in a room for the elderly and people with disabilities.

As a rule, the temperature of the whole house or individual rooms is based on only one climate microcontroller in the heating system. The best option for its location in the living room or bedroom, which should probably be the most visited place in the house.

Room thermostats need a free flow of air to sense the temperature, so they should not be covered by curtains or blocked by furniture. Appliances adjacent to the electric thermostat may interfere with the correct operation of the device. These include lamps, televisions, neighbor's boilers through the wall, touch switches.

Thermostatic control valves

A thermostatic valve is a simple solution to the problem of obtaining a coolant of a given temperature by mixing colder water with warmer water. The view of the three-way valve is shown below:

The thermostatic radiator valve allows you to control the temperature in the room by changing the flow of hot water through the radiator. They regulate the flow of hot water through the radiator, but do not control the boiler. Such devices must be installed in order to adjust the temperature that is needed in each individual room.

This idea should be considered as an addition to a thermal control plant. Also, such devices need periodic readjustment and regular performance checks (every six months during the change of operating modes).

Homemade external thermostat for the boiler: instructions

Below is a diagram of a home-made thermostat for a boiler, which is assembled on Atmega-8 and 566 series microcircuits, a liquid crystal display, a photocell and several temperature sensors. The programmable Atmega-8 chip is responsible for compliance with the set parameters of the thermostat settings.

In fact, this circuit turns the boiler on or off when the outdoor temperature drops (rises) (sensor U2), and also performs these actions when the temperature in the room changes (sensor U1). Adjustment of the work of two timers is provided, which allow you to adjust the time of these processes. A piece of circuit with a photoresistor affects the process of turning on the boiler according to the time of day.

Sensor U1 is located directly in the room, and sensor U2 is outside. It is connected to the boiler and installed next to it. If necessary, you can add the electrical part of the circuit, which allows you to turn on and off high-power units:

Another thermostat circuit with one control parameter based on the K561LA7 chip:

The assembled thermostat based on the K651LA7 chip is simple and easy to adjust. Our thermostat is a special thermistor that significantly reduces resistance when heated. This resistor is connected to the electricity voltage divider network. This circuit also has a resistor R2, with which we can set the required temperature. Based on such a scheme, you can make a thermostat for any boiler: Baksi, Ariston, Evp, Don.

Another circuit for a thermostat based on a microcontroller:

The device is assembled on the basis of the PIC16F84A microcontroller. The role of the sensor is performed by a digital thermometer DS18B20. A small relay controls the load. Microswitches set the temperature that is displayed on the indicators. Before assembly, you will need to program the microcontroller. First, erase everything from the chip and then reprogram, and then assemble and use it to your health. The device is not capricious and works fine.

The cost of parts is 300-400 rubles. A similar regulator model costs five times more.

A few last tips:

• although different versions of thermostats are suitable for most models, it is still desirable that the thermostat for the boiler and the boiler itself be produced by the same manufacturer, this will greatly simplify the installation and the operation process itself;
• before buying such equipment, you need to calculate the area of ​​\u200b\u200bthe room and the required temperature in order to avoid “downtime” of equipment, and changing wiring due to the connection of devices of higher power;
• before installing the equipment, you need to take care of the thermal insulation of the room, otherwise high heat losses will be inevitable, and this is an additional expense item;
• if you are unsure that you need to purchase expensive equipment, then you can conduct a consumer experiment. Get a cheaper mechanical thermostat, adjust it and see the result.

A device that regulates the operation 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 controller for the heating boiler. That is, this is an apparatus that provides not only 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 buy a thermostat

When the operation of the 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, the start of water heating is performed for a short time - no more than 10 minutes. The constant circulation of water in the system is provided by pumping equipment, which operates regardless of the state of the heating elements.

Such an organization of the operation of the climate system is fraught with a significant consumption of electrical energy. In addition, this mode leads to rapid wear of all boiler systems. Therefore, it is not at all surprising that room thermostats have gained such popularity all over the world. In some Western countries, their installation is even considered mandatory. Since if the house is heated with a gas boiler, the presence of a “home controller” significantly reduces the cost of gas and electricity, 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 drops or rises relative to the set parameters, it either turns on or off the boiler and the pump. Such a system guarantees the owner of the thermostat a number of advantages:

• fully provides control over maintaining the required temperature in the home, which means that even on days of sharp temperature fluctuations outside the window, in a house where the thermostat works, coziness and comfort will always reign;
• 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 health 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, while they may vary depending on:

1. Type of boiler operation modes control:
   • wireless;
   • wired.
2. Functionality level:
   • simple;
   • provided with hydrostat function;
   • programmable.

The wireless room thermostat for a gas boiler is able to regulate the level of operation of the boiler and the heating of the air in the premises using a radio signal. For wired, only the method of connecting to the controller via wired connections is relevant.

The scope of possibilities of thermostats can be different. Less expensive - simple, reliable and durable wired thermostats do an excellent job with the list of basic functions, steadily maintaining the level of set temperatures in the room (usually in the range of 10-30 ° 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 programmable room thermostat for a gas boiler.

By purchasing such a device, you can use the 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;
• control over fuel consumption and serviceability of gas heating boiler systems.

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

Connecting wireless option

The principle of operation of a room thermostat for a gas boiler is quite simple, but wireless thermostats remain the most convenient in terms of connection. Such a model, as a rule, consists of a couple of blocks:

• block for installation near a gas boiler (by connecting to a controller or gas valve);
• block 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 the terminals, and the transfer of information from one unit to another is due to the use of a radio channel. Perhaps the only disadvantage of wireless 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 level, which, of course, is 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 either have to be masked or laid in the body of the wall into the channel formed after it has been shredded.

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

It is also highly undesirable to install it near household, third-party climate control equipment and heating appliances, as well as in places where direct sunlight will fall on the device.

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

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 need to be connected to the mains and batteries. However, in the course of work on its connection, it will also not be possible to avoid fiddling with wires. But in this case, we are talking about wires that provide communication between the device and controlled climate technology.

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

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

About the specifics of the setting

After you have successfully connected 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;
• Determination of the optimal delay period for the operation of the thermostat sensors (a window open for a short time or, conversely, the heat flow from the switched on hair dryer can “mislead” the device’s sensors, but turning on 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 regime depending on the time of day or day of the week (for example, on weekdays, when there is no one at home, you can lower the air temperature by several degrees, providing fuel savings, a couple of hours before the inhabitants of the house return, the device will turn itself on , will adjust the temperature until it rises to a comfortable level).

About compatibility issues

The method of connecting the thermostat to the boiler is largely determined by the choice of the thermostat model and can be performed both from the controller, from the battery, and from the network.

You can often meet the recommendations of boiler manufacturers when purchasing a simple or programmable thermostat for a gas boiler, focus on the boiler manufacturer and its recommendations. In principle, this advice is worth heeding, although, having looked through the pages of numerous forums where the issues of connecting climate equipment are discussed, one can often find the opinion that, for the most part, products from different brands “get along” perfectly without conflict.

But the parameter that is really worth considering when deciding to buy a temperature sensor for a heating boiler in a regular climate or household appliance store or an online store is the area of ​​\u200b\u200bthe room heated by the boiler and the most preferred temperature regime.

TOP thermostats 2017–2018

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

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 network about the successful symbiosis of the climate equipment of 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 temperature sensor calibration, has backup power options. The appliance can adjust the room temperature according to the time of day and the days of the week.

The video details 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 regime not only for the week ahead, but also for any hour of the upcoming week. There are also less complex, but cheaper options that “know how” to set the desired temperature regime for the next 24 hours. However, the availability of hourly programming helps homeowners solve a lot of problems, including saving gas and electricity.

We offer 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 parameters of the solar system (if connected);
• display of energy audit report (kW), solar system performance, reduction of CO2 emissions, hot water storage;
• electronic room temperature sensor;
• easy-to-manage daily and weekly programming of the heating mode;
• easy-to-manage daily and weekly programming of the DHW mode (in case of connecting an external boiler 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 temperature controller can control the modulation of a gas burner. Thermostats from other manufacturers cannot be connected in this way to the Proterm boiler. In addition, on the display of some models from Protherm, you can see not only the set operating modes of the boiler, but also the error codes that occur. In addition, the system, if necessary, is able to restart the boiler itself. In this way, the temperature of the boiler is regulated.

Buderus

Connecting a room thermostat to a Buderus gas boiler will also create fewer problems when it comes to 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 is not difficult. Moreover, the quality of this technique is rarely satisfactory.

Ferroli

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

Baxi

The thermostat for the Baxi gas boiler has also become a trend, it is easy to install and manage, also featuring an intuitive adjustment system and providing significant savings to home owners.

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

conclusions

The thermostats of listed companies successfully help to solve problems such as:

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

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

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

Why do I need a thermostat for a heating boiler (temperature controller) in rooms

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

• create in such a way that the formation of useful infrared radiation occurs with maximum efficiency.
• In gas boilers, constant flame control systems are installed that optimize the combustion process.
• When used, chambers of complex shape are created on the path of combustion products output. 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 needed.

To fulfill the latter condition, it will be necessary for the heating boiler (temperature controller). With the correct use of this technique, you can get at your disposal the following advantages:

• Maintenance of the set temperature in automatic mode, without the need for careful control.
• Saving energy resources (cash) up to 30% or more.
• Possibility of remote control, quick transition to special modes.
• Extending the service life of boilers through careful operation.

Note! Optimizing the operation of the equipment using a temperature sensor for a heating boiler will extend the battery life when the mains power is turned off. From the built-in battery, the equipment will work for a long time, which will increase the time for calling specialists and eliminating an emergency.

Functions of a temperature sensor for a heating boiler: regulation of the temperature of the heat carrier

A modern boiler control system consists of several parts:

• In this embodiment, the room temperature and outside air temperature sensors are connected directly to it.
• Power is provided by the AC adapter. Built-in accumulators provide maintenance of working capacity at disconnection of 220V.
• For remote control, a GSM unit is installed here. With it, the user will receive operational data on the temperature inside the premises. If desired, it turns on the desired mode by applying 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 a pump. This is more economical than the built-in thermostat discussed above. The air temperature decreases more slowly than the coolant, so the ignition frequency of the burner is reduced. In such conditions, the service life of equipment is extended.

Important! Boilers compatible with room thermostats must have special “Room Thermostat” input sockets on the control board. The corresponding possibilities are indicated in the manufacturer's official instructions.

The algorithm of operation of such equipment in a complex deserves high marks. If the sun came out, the temperature rose outside, the boiler would not turn on. It became colder in the room after airing - no need to reconfigure the heating equipment and further set the regulators to the normal position. The necessary actions will be performed automatically. Literally in one season, you can recoup the investment made. But in any case, a more thorough study of the parameters of equipment and models on the market is useful.

In order to correctly select the appropriate equipment, it is necessary to consider the need for 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 has become warmer outside, heating will continue even when the boiler is turned off by the thermostat. If there are sensors outside the room, the desired command will be given faster. The actual savings in the process of their active use is small. Therefore, these enhanced features are evaluated in conjunction with a certain increase in cost.

Varieties of technology and selection criteria

For heating boilers (temperature controllers) are equipped with various hardware and software blocks. The following are additional functionalities and technical features of modern models:

How to connect a thermostat to a boiler

It is more convenient to work with temperature controllers for heating boilers that support wireless connection. For example, the algorithm for installing 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 desirable to prevent unwanted external influences on the thermostat. It is fixed on the interior walls, away from, not in direct sunlight. But installation in niches, other places where the natural circulation of air flows is difficult is not recommended.
• Less distance will be obtained if there are thick reinforced concrete walls and other obstacles to the propagation of radio waves on the corresponding line. Signal transmission is carried out at a carrier frequency of 868 MHz.
• If several kits are mounted on the site, you can change the encoding. For this, a DIP switch is used. Assume a choice of 32 options. The distance between the receiving units is kept more than 90 cm to avoid false positives.
• The Salus/Controls iT500 is built to be safe, allowing it to be used near gas appliances.

The previous operations are performed with the 220 V power 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 is associated with the laying of wired communications. Therefore, the total costs may increase significantly compared to the preliminary plan. More complex sets use the radio band to transmit control and control signals. The installation of such products is not difficult to carry out independently. Their high cost is due to advanced functionality.

Due to the ever-increasing energy costs, the demand for energy saving measures is growing along the way. Let's take a closer look at one of them - installing a thermostat for a heating boiler or thermostat.

Given the rise in energy prices, the issue of energy conservation is extremely acute. That is why a large number of models of heating devices that consume fuel economically have been developed. However, the equipment itself is not enough. The most rational use of energy resources will help the thermostat for the heating boiler (thermostat), which allows you to control and maintain the set air temperature in the heated room.

Purpose of thermostats for heating boilers

To be able to control the energy consumption of heating equipment, it is equipped with special devices - thermostats. These devices allow you to use fuel efficiently by turning off the equipment when the set temperature level is reached. Thermoregulators are used for electric boilers, gas and solid fuel boilers, as well as convectors, heaters and other heating systems.

To achieve economical operation of the heating boiler, the thermostat turns on the equipment when the temperature drops below the set temperature and turns it off when the set value is reached. This method avoids unreasonable consumption of gas or electricity, when, for example, some of the rooms are located on the sunny side and less heat is needed to heat them than for other rooms.

Useful advice! Even a slight decrease in temperature within 1 degree helps to reduce energy consumption by 4-6%.

In addition, with the help of thermostats, you can set the operating mode of the heating system, in which the temperature in the absence of people in the house or at night will be 4-5 ° C lower. Thanks to this, savings in electricity or gas consumption of about 30% can be achieved. Thus, if your heating equipment does not have such a built-in device, it would be advisable to buy a thermostat for a heating boiler. The temperature controller will provide a solution to the problem of energy overruns.

Types of thermostats for heating boilers

Equipping heating equipment with thermostats allows you to maintain a given temperature climate in the room with an accuracy of 1 to 0.5 degrees. They control the operation of the heating system using various actuators. There are electromechanical and electronic thermostats. The design of a mechanical thermostat for a heating boiler has an on / off key and a rotary button to control the temperature.

Electronic or programmable thermostats are more advanced, but simple and straightforward to use. With their help, you can set the daily temperature cycle: in this case, the boiler will automatically switch to the specified mode. Such devices can regulate both the entire heating system and individual heating units.

There is a classification of devices into wired and remote-controlled. For the former, the connection of conductors is important, as well as external protection against mechanical damage. The quality of the signal supplied from the boiler to the controller, which informs about the flow of coolant into the circuit, depends on this. During installation, the question may arise of how to mask the signal line so that it is invisible.

In the wireless thermostat for the boiler, control is carried out by transmitting a radio signal. Such a device has two blocks, one of which is mounted in close proximity to the heating boiler, connecting to the equipment terminals. The second node is located indoors. There is a dedicated radio channel between the two blocks. The control unit is equipped with a display and a control keyboard.

Depending on the degree of automation, thermostats can be digital or analog. The operation of digital devices is based on the signal of microcircuits, due to which the device can fix and apply several specified modes. Analog thermostats are controlled manually by means of a mechanical regulator connected to a rheostat.

Thermostat for a heating boiler (thermostat): which one is better to choose

Before you buy a thermostat for the boiler, you need to decide on the type of device. To do this, you need to understand what is the fundamental difference between models of room mechanical thermostats and electronic ones. There is an opinion that the latter are difficult to configure and they are unreliable, but this is not so.

The principle of operation of a mechanical thermostat for a heating boiler
In most cases, mechanical thermostats for heating boilers are used in gas installations. This is due to the fact that manufacturers of gas boilers initially produce devices that are compatible specifically with mechanical models of thermostats. The design of a mechanical thermostat has a gas membrane, inside of which there is a special gas.

When the temperature deviates from the norm, the volume of gas inside the membrane changes and the mechanism for closing or opening the heating boiler power system is triggered, respectively. This is a fairly simple way to control the operation of the boiler, when its operation depends on the temperature indicator not of the coolant, but of the air in the heated room.

Using a mechanical thermostat model, you can set an acceptable temperature by turning a round button with divisions, which is connected to the membrane. Thus, there is an approach or removal of the walls of the membrane to the control device: this is how we set the temperature at which the connection or break of contact will occur.

Useful advice! The simple design of mechanical thermostats for heating boilers allows you to make the device yourself.

Among mechanical devices, Siemens room thermostats have proven themselves well. Models RAA21, RAA31 have a temperature setting range of 8-30°C. Devices with a laconic design are mounted like ordinary switches and do not violate the integrity of the interior line. Easy to install and manage. The estimated price of a room thermostat for a gas boiler is 1500 rubles.

Of the advantages of mechanical thermostats, one can single out low cost, the possibility of repair and resistance to power surges. The disadvantages include the low sensitivity of the device to temperature changes. The inaccuracy can be up to 3°C.

Advantages of electronic wireless thermostats for gas boilers

The use of programmable wireless thermostats for gas boilers makes it possible not only to control the operation of heating devices, but also to do it remotely. Electronic regulation allows you to set different operating modes of the boiler, depending not only on temperature, but also on a certain time of day.

By purchasing a wireless thermostat for a gas boiler with programmable functions, you can count on significant fuel savings. The acquisition of a relatively expensive device justifies itself within two heating seasons.

Modern models of thermostats are equipped with a GSM standard, which allows you to transfer information to a mobile phone via sms. Given the fact that boilers from leading manufacturers support Wi-Fi technology, and their electronic control unit is connected to a thermostat, it is possible to configure the operation of heating equipment via the Internet. Know-how in this area is the development of special applications for smartphones.

Convenient operation system, no need for wires, automatic control of equipment are important advantages in using a wireless room thermostat for a gas boiler. You can buy devices with additional options, such as joint control of the gas burner unit, equipment adjustment depending on the outdoor temperature, system diagnostics and other functions.

Among the shortcomings of programmable room thermostats, one can, perhaps, single out the possible incompatibility of the latter with boilers, depending on their manufacturer. Such a snag appeared due to the large number of manufacturers of electronic equipment and gas heating equipment.

Useful advice! Before you buy a thermostat for a gas boiler, you need to inquire about the compatibility of the device with the model of gas equipment from a specialist in the selling company.

An excellent example for autonomous heating are the models of room thermostats for the Baxi gas boiler. Devices allow you to set the temperature depending on the time of day and season, adjust the temperature in different rooms. In addition, they provide an economical mode of operation of gas equipment. Estimated price of a thermostat for a Baxi heating boiler of the AURATON 2030 RTH model is 6900 rubles.

Functions of room thermostats for gas boilers

Before you buy a room thermostat for a gas boiler of one type or another, you should familiarize yourself with its functionality. It should be noted that when choosing between analog and digital models, the latter have a lot of advantages and, accordingly, their price is higher.

However, the use of a programmable room thermostat for a heating boiler can significantly reduce the frequency of turning on / off the equipment, which has a positive effect on its operation as a whole.

An extremely important feature of the room thermostat for the boiler is the programming function, which makes it possible to set a comfortable microclimate depending on the time of day, weather conditions and other factors. The available timer allows you to set the desired parameters, taking into account the days of the week (working, weekends), the calendar season and other settings. This is very convenient for those who work in shifts or work part-time.

The main advantages of a programmable room thermostat for a gas boiler:

• remote control of the heater;
• the “day / night” setting makes it possible to set an individual level of heating, taking into account a certain time of day;
• ease of control allows you to quickly reconfigure the temperature in the room;

On some models of thermostats, the diagram is shown on the back of the decorative cover. All modern boiler models have connection points for a thermostat that will control the operation of heating equipment. Fixing the device is carried out by means of a terminal on the boiler at the appropriate point or using a thermostat cable (included in the kit).

According to professionals, wireless room thermostats should be installed in living rooms away from existing household electrical equipment (TV, refrigerator, lamps, etc.), since proximity to the heat radiated from them can lead to incorrect operation of the device. Some recommendations for installing a wireless thermostat for a gas boiler:

• for the correct measurement of the temperature in the room, it is necessary to ensure free access of air to the thermostat;
• it is not recommended to cover the devices with furniture or heavy curtains;
• the device should be located in the coolest rooms or in residential areas where residents spend the most time;

• avoid direct sunlight on the device;
• do not mount the device near radiators or heaters;
• the devices must not be located in the draft area.

Useful advice! Room thermostat sensors for heating are triggered when the room temperature changes by 0.25 degrees.

Heating control with a thermostat for a gas boiler

You can control the operation of heating equipment using the manual setting or by means of a thermostat for a gas heating boiler. I would like to note that using manual settings, you can set the temperature of the coolant in the system. Such functioning of the equipment does not react in any way to changes in the air temperature in the room, and if this occurs, you will have to manually reconfigure the boiler again.

The operation of the boiler in the case of manual control is associated with frequent switching on and off of the equipment, as well as the operation of the circulation pump, regardless of whether the unit is in operating or standby mode. This causes heating equipment to wear out quickly and does not contribute to efficient fuel consumption.

If we are talking about control using a thermostat for a gas boiler, then such a device sets the optimal mode for the unit, taking into account the air temperature in the heated room. If, for example, there was a sudden warming and the room received additional heat from the sun's rays, the thermostat will instantly react and give a signal to the control device to turn off the boiler.

Considering that with the help of a thermostat (temperature controller) for a gas boiler, you can set the required temperature in the room, heating will be carried out only if it is lowered. Thus, if the device is set to 20 ° C, and during the day the room warms up also due to solar heat or the operation of cooking appliances, the boiler will be in the standby state for a long time.

In this case, fuel consumption will be significantly lower. Before you buy a thermostat for a gas heating boiler, you should ask how to properly configure the device.

Setting the thermostat (temperature controller) for the heating boiler

After you buy a thermostat for a heating boiler and connect it to heating equipment, it will need to be configured. Each product comes with an instruction manual that explains how to set it up. Having carefully studied it, you can independently set the necessary mode that meets the individual level of microclimate comfort.

On the external panel of the device there are buttons and switches, through which the setting is carried out. The switches allow you to control the heating and air conditioning of the air space, start delay (does not allow the boiler to start when the temperature drops for a short time, for example, a draft) and temperature deviation (if you set the fluctuation value to 1 ° C, then switching on or off will be available when the temperature rises or falls by 0.5 degrees).

By means of buttons two modes are set: optimum and economical. Thus, during the day the temperature will be at the optimum value, at night the temperature will drop to a level sufficient for a pleasant sleep. This mode will significantly save on energy resources. Various models of thermostats have several preset modes, one of which can be selected for use.

Useful advice! In rooms where children and the elderly are most often present, it is recommended not to lower the temperature below 22°C.

Temperature controllers for electric heating boilers: how to choose a device

In places where gas supply is not available, electric boilers are used for space heating. Among the advantages of such equipment, there is no need for a chimney device, ease of installation, environmental friendliness, quiet operation, high performance and equipment with a control unit for functioning in automatic mode.

The disadvantages of electric heating include one, but quite a significant drawback - a significant consumption of electricity. This leads to the high cost of electrical heating systems. Installing a thermostat for an electric heating boiler will reduce energy costs by 20 to 30% and set up an individual heating mode for each room.

As with other types of heating equipment, it is possible to use an electronic or mechanical room thermostat for electric boilers. The type of device is selected depending on what options are needed in your particular case. Mechanical models are simple and inexpensive, but may not work accurately. Electronic programmers are accurate, multifunctional and allow the equipment to operate in an economical mode without the intervention of the owner.

Before you buy a thermostat for an electric boiler, you need to decide on the temperature regime used and take into account the area of ​​\u200b\u200bthe heated room. It is recommended that the purchased thermostat and electric boiler be produced by the same manufacturer. Models manufactured by Baxi, Ariston, Salus Controls ltd, BOSH and others are popular.

Useful advice! A voltage stabilizer will help to ensure uninterrupted operation of the electric boiler and electronic thermostat in case of possible voltage drops in the network.
