Given the rise in energy prices, the issue of energy conservation is extremely acute. That is why it was developed a large number of models of heating devices, economical fuel consumption. However, the equipment itself is not enough. The most rational use of energy will help the thermostat for the heating boiler (thermostat), which allows you to control and maintain the set temperature of the air in a 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. Apply temperature controllers 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 setpoint and turns off when the set value is reached. This method allows you to avoid unnecessary consumption of gas or electricity, when, for example, some of the rooms are located on the sunny side and for their heating less heat is needed than for other rooms.
Helpful advice! Even a slight decrease in temperature within 1 degree helps to reduce energy consumption by 4-6%.
In addition, using thermostats, you can set the mode of operation 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, it is possible to achieve savings of electricity or gas consumption of about 30%. Thus, if your heating equipment does not have such an integrated appliance, it would be advisable to buy a thermostat for a heating boiler. The temperature controller will provide a solution to the problem of energy waste.
Equipping heating equipment with thermostats allows you to maintain a predetermined temperature in the room with an accuracy of 1 to 0.5 degrees. They control the operation of the heating system through various actuators. There are electromechanical and electronic thermostats. The design of a mechanical thermostat for a heating boiler has an on / off button and a rotary knob for controlling the temperature mode.
Electronic or programmable thermostats have a more advanced structure, but are simple and easy to use. With their help, you can adjust 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 for wire and with remote control. For the former, the connection of conductors is important, as well as external protection against mechanical damage. The quality of the signal from the boiler to the controller, which notifies the flow of coolant into the circuit, depends on this. During installation, there may be a question of how to mask the signal line so that it is invisible.
In a wireless thermostat for a boiler, control is achieved by transmitting a radio signal. Such a device has two units, one of which is mounted in close proximity to the heating boiler, connecting to the terminals of the equipment. The second node is located in the room. Between the two blocks there is a dedicated radio communication channel. The control unit is equipped with a display and 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, thanks to which the device can fix and use several specified modes. Analog thermostats are controlled manually by means of a mechanical regulator connected to the rheostat.
Before you buy a thermostat for the boiler, you must decide on the choice of the type of device. To do this, it is necessary to understand what is the fundamental difference between the models of room mechanical thermostats and electronic. Argued that the latter is difficult to configure and they are unreliable, but it is not.
In most cases, mechanical temperature controllers for the heating boiler are used in gas installations. This is due to the fact that manufacturers of gas boilers initially produce devices that are compatible with mechanical models of thermostats. The design of the mechanical thermostat has a gas membrane, inside which there is a special gas.
If the temperature deviates from the norm, the volume of gas inside the membrane changes and the mechanism for closing or opening the boiler’s power supply system changes accordingly. This is a fairly simple way to control the operation of the boiler, when its operation depends on the temperature indicator not of the heat carrier, but of the air in the heated room.
Using the mechanical model of the thermostat, it is possible to set an acceptable temperature condition by turning a circular graduated button that has a connection with the membrane. Thus, there is an approach or removal of the walls of the membrane to the control device: so we adjust the temperature at which the connection or rupture of the contact will occur.
Helpful 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. The models RAA21, RAA31 have a temperature setting range of 8-30 ° C.

After the model is selected, the question arises how to connect the thermostat to an electric boiler or a gas heating unit. The device is connected according to the recommendations specified by the manufacturer in the technical data sheet for the equipment. It is only necessary to find the necessary section in the documentation, where the method of connecting additional devices to the boiler and all the required diagrams will be described.
On some models of thermostats, the diagram is shown on the reverse side of the decorative cover. All modern models of boilers have connection points for a thermostat that will control the operation of heating equipment. The device is fixed 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 far 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:
- to properly measure the temperature in the room, it is necessary to ensure free access of air to the thermostat;
- It is not recommended to close the device with furniture or heavy curtains;
- the appliance should be located in the coolest rooms or in residential areas where residents spend the most time;
- Avoid exposure to direct sunlight.
- do not install the device near radiators or heaters;
- Do not allow devices to be in a drafts area.
Helpful advice! The sensors of the room thermostat for heating are triggered when the temperature in the room changes by 0.25 degrees.
It is possible to control the operation of the heating equipment using the setting in manual mode or by means of a thermostat for a gas heating boiler. It should be noted that with the help of manual settings you can set the temperature of the coolant in the system. Such equipment operation doesn’t react to the change in air temperature in the room, and if that happens, you will have to reconfigure the boiler again manually.
The operation of the boiler in the case of manual control is associated with frequent switching on and off of equipment, as well as with the operation of a circular pump, regardless of whether the unit is in operation or in waiting 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 sharp warming and the room received additional heat from the sun’s rays, the thermostat will instantly react and give a signal to the control unit to turn off the boiler.
Considering that using a temperature controller (temperature controller) for a gas boiler, you can set the desired temperature in the room, heating will be performed only if it is lowered. Thus, if the device is set to 20 ° C, and during the day the room is warmed up also by solar heat or cooking appliances, the boiler will be in the waiting stage 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.
After you buy the thermostat for the heating boiler and connect it to the heating equipment, it will need to be configured. Each product is accompanied by an instruction in which the order of adjustment is given. Having carefully studied it, you can independently set the required mode that corresponds to the individual level of comfort of the microclimate.
On the external panel of the device there are buttons and switches through which the setting is carried out. Switches allow you to control the heating and air-conditioning, delayed on (it does not allow the boiler to start working with a brief decrease in temperature, for example, a draft) and temperature deviation (if you set the oscillation value to 1 ° C, then on or off will be available when the temperature increases or decreases at 0.5 degrees).
By means of buttons two modes are set: optimum and economical. Thus, during the day, the temperature will be provided with an optimal value, at night the temperature will drop to a level sufficient for a pleasant sleep. This mode will significantly save on energy. Different models of thermostats have several established modes, one of which can be selected for use.
Helpful advice! In rooms where children and older people are most often, it is recommended not to lower the temperature below 22 ° C.
In places where gas supply is not available, electric boilers are used for space heating. Among the advantages of such equipment are the absence of the need for a chimney device, ease of installation, environmental friendliness, quiet operation, high performance and equipment with a control unit for automatic operation.
