Thermostat for heating boiler (thermostat): types, functions, prices
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 have been developed that use fuel economically. However, the equipment itself is not enough. The most rational way to spend energy resources will help the thermostat for the heating boiler (thermostat), which allows you to control and maintain the set mode of air temperature in a heated room.
Purpose of thermoregulators for heating boilers
In order to be able to manage the energy consumption of heating equipment, it is equipped with special devices — thermoregulators. These devices make it possible to use fuel efficiently by shutting down 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 value and turns 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 the rest of the 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 thermoregulators, it is possible to set the operating mode of the heating system, at 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 in electricity or gas consumption of about 30%. 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 overspending.
Types of thermostats for heating boilers
Equipping heating equipment with thermostats allows you to maintain a preset 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 the mechanical thermostat for the heating boiler has an on/off key and a rotary button for controlling the temperature regime.
Electronic or programmable thermostats have a more advanced structure, but are simple and intuitive to use. With their help, you can adjust the daily temperature cycle: in this case, the boiler will automatically switch to the preset mode. Such devices can regulate both the entire heating system and individual heating units.
There is a classification of devices for wired and remote-controlled. For the former, the connection of the conductors is important, as well as external protection against mechanical damage. The quality of the signal supplied from the boiler to the controller notifying about the flow of coolant into the circuit depends on this. During installation, the question may arise about 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 terminals of the equipment. The second node is located indoors. There is a dedicated radio communication 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 the microcircuits, so that the device can record and apply several preset modes. Analog thermostats are controlled manually by means of a mechanical regulator connected to a rheostat.
Thermostat for heating boiler (thermostat): which one is better to choose
Before you buy a thermostat for a boiler, you need to decide on the type of device. To do this, it is necessary to understand what is the fundamental difference between the models of room mechanical and electronic thermostats. There is an opinion that the latter are difficult to configure and unreliable, but this is not the case.
The principle of operation of a mechanical thermostat for a heating boiler
In most cases, mechanical thermoregulators for a 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 thermoregulators. In the design of the mechanical thermostat there is a gas membrane, inside which there is a special gas.
When the temperature deviates from the norm, the volume of gas inside the membrane changes and, accordingly, the mechanism of closing or opening the power supply system of the heating boiler is triggered. This is a fairly simple way to control the operation of the boiler, when its functioning depends on the temperature indicator not of the coolant, but of the air in the heated room.
Using a mechanical model of the thermostat, it is possible to set an acceptable temperature regime by turning a round button with divisions, which has a connection to the membrane. Thus, the membrane walls approach or remove to the control device: this is how we will set the temperature at which the connection or contact break 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 concise design are mounted like ordinary switches and do not violate the integrity of the interior line. Easy to install and manage. The approximate price of a room thermostat for a gas boiler is 1500 rubles.
Among the advantages of mechanical thermoregulators, it is possible to distinguish a small cost, the possibility of repair and resistance to voltage 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 thermoregulators for gas boilers
The use of programmable wireless thermoregulators 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 the 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 purchase of a relatively expensive device justifies itself during two heating seasons.
Modern models of thermoregulators are equipped with a GSM standard, which allows you to transmit information to a mobile phone via SMS messages. Considering 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 over the Internet. The know-how in this area is the development of special applications for a smartphone.
A convenient operating system, no need for wires, and 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.
Of the disadvantages of programmable room temperature controllers, it is possible to single out, perhaps, 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 buying a thermostat for a gas boiler, it is necessary to inquire about the compatibility of the device with the model of gas equipment from a specialist of the selling company.
An excellent example for autonomous heating are models of room thermostats for a Baxi gas boiler. The 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. The approximate price of the thermostat for the 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 making a choice between analog and digital models, the latter have a lot of advantages and, accordingly, the price for them is higher.
However, the use of a programmable room thermostat for a heating boiler can significantly reduce the frequency of on/off 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 adjust a comfortable microclimate depending on the time of day, weather conditions and other factors. The available timer allows you to set the necessary parameters, taking into account the days of the week (working days, weekends), calendar season and other settings. This is very convenient for those who have a shift work schedule or work part-time.
The main advantages of a programmable room thermostat for a gas boiler:
- remote control of the heating device operation;
- the “day/night” setting makes it possible to set an individual heating level taking into account a certain time of day;
- easy operation allows you to quickly reconfigure the temperature regime in the room;
- the programming option makes it possible to configure the operation of the equipment taking into account weather changes;
- due to minimal on/offs, wear is minimized and the operational life of the heating equipment is extended.;
- significant savings in energy consumption;
- high accuracy and reliability in operation.
Useful advice! By purchasing a room thermostat for a programmable boiler, you get the opportunity to control the heating equipment at any time of the day, regardless of your presence in the house.
Connection diagram of the thermostat to the heating boiler
After the model is selected, the question arises how to connect the thermostat to an electric boiler or 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 will be described and all the required circuits are given.
On some models of thermoregulators, 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 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:
- 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 cover the devices with pieces of furniture or heavy curtains;
- the device should be placed in the coolest rooms or in residential areas where residents spend the most time;
- it is necessary to avoid direct sunlight on the device;
- it is not necessary to mount the device next to radiators or heaters;
- it is impossible for the devices to be in the area of drafts.
Useful advice! The sensors of the room thermostat for heating are triggered when the room temperature changes by 0.25 degrees.
Heating control using a thermostat for a gas boiler
You can control the operation of the heating equipment using the manual setting or by means of a thermostat for a gas heating boiler. I would like to note that with the help of 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 such has occurred, you will have to reconfigure the boiler manually again.
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 the circular pump, regardless of whether the unit is in working or waiting mode. This leads the heating equipment to rapid wear 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 signal the control device to turn off the boiler.
Considering that with the help of a thermostat (temperature controller) for a gas boiler it is possible to set the required temperature value in the room, heating will be carried out only if it is lowered. Thus, if the device is set at 20 ° C, and during the day the room warmed up also due to solar heat or the operation of cooking appliances, the boiler will be in the waiting stage for a long time.
In this case, the 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 up a temperature controller (temperature controller) for a heating boiler
After you buy a thermostat for a heating boiler and connect it to the heating equipment, it will need to be configured. Instructions are attached to each product, which provides the setup procedure. Having carefully studied it, you can independently set the necessary mode that meets 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. The switches allow you to control the heating and air conditioning of the air space, the delay of switching on (does not allow the boiler to start working with a short-term decrease in temperature, 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 increases or decreases by 0.5 degrees).
Using the buttons, two modes are set: optimal and economical. Thus, the temperature with the optimal value will be provided during the day, at night the temperature will decrease to a level sufficient for a pleasant sleep. This mode will significantly save on energy resources. Different models of thermoregulators have several set modes, one of which can be selected for use.
Useful advice! In rooms where children and elderly people are most often located, it is recommended not to lower the temperature below 22 ° C.
Thermoregulators for electric heating boilers: how to choose a device
In places where gas supply is not available, electric boilers are used for heating the premises. Among the advantages of such equipment, there is no need for a chimney device, ease of installation, environmental friendliness, quiet operation, high productivity and equipment with a control unit for automatic operation.
The disadvantages of electric heating include one, but rather significant drawback — significant electricity consumption. This leads to a high cost of electric heating systems. Installing a thermostat for an electric heating boiler will reduce energy consumption in the range from 20 to 30% and set up an individual heating mode for each room.
As for 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 they can work inaccurately. Electronic programmers are accurate, multifunctional and allow the equipment to operate in an economical mode without the intervention of the owner.
Before buying a thermostat for an electric boiler, it is necessary to determine the temperature regime used and take into account the area of the heated room. It is recommended that the purchased thermostat and electric boiler be produced by the same manufacturer. Models produced by Baxi, Ariston, Salus Controls ltd, BOSH and others are popular.
Useful advice! A voltage stabilizer will help to ensure the smooth operation of the electric boiler and electronic thermostat in case of possible voltage fluctuations in the network.
