When heating a house with a gas boiler, the issue of reducing the cost of electricity and fuel, increasing or extending the service life of equipment, maintaining a comfortable temperature is always relevant. Thermostat for gas boiler allows you to control the operation of the heating device, providing comfort in the home.
Room thermostat for gas boiler
Instruments for controlling the operating modes of boilers are divided into two main types:
Functionally, room thermostats for heating are:
Simple devices are only able to maintain a stable set temperature in the room, do not have a direct effect on reducing gas consumption.
Programmers have a number of functions:
The hydrostat function allows you to control the humidity in the rooms, reduce or increase it, depending on the preferences and desires of the owner.
Wired devices are distinguished by their reliability and simplicity of design, low cost, and long service life. A thermostat for a heating boiler of this type is able to maintain only one temperature regime, which is set by changing the position located on front side, pens. 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 the battery.
A variety of wireless thermostats The main disadvantage of this type of device is that it is possible to set only one temperature value. To change it, you must reinstall the handle to a different position. In addition, certain inconveniences are caused by cable laying, therefore it is better to install a wired thermostat to a gas boiler during finishing works and installation heating system.
If the heating system is already installed, it is more convenient to install a wireless programmable thermostat for a gas boiler, during the installation of which the aesthetics of the interior will not be disturbed.
The wireless thermostat for gas boilers consists of two units. One of them is placed near the heater and is connected to the gas valve or controller using terminals. Another is installed in the room from which it is planned to monitor the operation of the boiler equipment.
Communication between the blocks is carried out over a radio channel. For ease of use, the control unit is equipped with a miniature keyboard and a small LCD display.
A 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 drawback of devices of this type is the limited resource 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 be guided only by the readings of its meters and excessively heat the coolant.
All modern thermostats for heating boilers, powered by batteries, have a warning function about the state of charge of the batteries.
A room thermostat for a gas boiler allows you to fully automate the heating control process.
Gas boilers work cyclically. When installing the automation, the gas is supplied and the burner is turned on only if the temperature of the coolant drops to the value set by the consumer. If the sensors are missing or defective, it is necessary to adjust the heating system manually, 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.
How a room thermostat works A room thermostat for a heating boiler is used to set and maintain a user-specified mode.
The thermostat works according to the following principle. The air temperature sensor allows you to adjust the thermostat so that the gas heater is turned on only when the temperature rises below or above the set temperature range and only for the required period of time. If for the boiler the main parameter is the temperature of the heating agent, then for the thermostat it is the air temperature in the room in which it is installed.
Having set the minimum comfortable temperature for yourself, you no longer need to worry about monitoring the operation of the boiler. As soon as the air temperature drops below the preset limit, the remote thermostat for the gas boiler will automatically start the heater and pump. The same principle of operation is realized when the air temperature in the room rises - the boiler is automatically turned off.
The thermostat is not the most expensive thing, but not the cheapest one either. On the modern market a large number of brands of these devices from various manufacturers are presented, 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 cost, then it is better to opt for a 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 case with a mechanical room thermostat.
If, when choosing for you, saving energy is of decisive importance, and with them in the near future and 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, reduces the temperature in 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 take a close look not only at them, but also at boilers for non-volatile heat supply.
If the house has already been renovated, and there is no desire to chisel the walls under the channels for wires, the choice in favor of a wireless thermostat with an air temperature sensor is obvious.
Wireless programmer with air temperature sensor When buying, you must definitely consult a specialist and independently read the reviews for certain device models.
Many boiler manufacturers also recommend buying a thermostat of their own brand, explaining that the installation and installation of the device in this case will be much faster and easier, and control over the heating equipment will be more reliable. For example, for a Baxi gas boiler, you need to purchase a thermostat of the same brand. In practice, various devices do not conflict with each other in any way and no problems arise with their interconnection and subsequent operation.
When choosing a thermostat, it is necessary to take into account the area of the room in which it will be installed, and the range of desired temperatures is no less important.
The simplest devices cost about $ 40. Despite the fact that the cost of the devices is quite high, one should not forget about the savings in connection with the decrease in gas consumption - the thermostat will pay for itself soon.
The first and probably the most important advice- before connecting the wired thermostat, you must not start repair work in the room, otherwise, the interior decoration may 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 - grooves, and with already completed repairs, strobing can turn out to be a rather 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, there must be free space around it. Before connecting the room thermostat, 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.
Mechanical thermostat fixed to the wall Connecting a room thermostat to a wired-type gas boiler and installing it in a room is not at all difficult. The most important thing is to strictly follow the manufacturer's recommendations and not deviate from the instructions and diagrams attached to the device. The way of connecting the cable depends on the brand and type of thermostat.
The coldest living space in the house or the 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.
When operating the thermostat, you should adhere to a few simple rules to reduce heating costs:
The use of room temperature controllers allows you to create the most comfortable conditions for staying in rooms and operating heating equipment, and significantly save by reducing gas consumption. The temperature sensor installed in the room reacts sensitively 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 taking 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 management is a vital part of the efficient operation of a boiler and home heating system. Proper use of 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. A 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 by using this kind of automation. And the prices for energy carriers are quite high and every normal person wants to reduce his expenses.
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.
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 thermoelement.
Structurally, a thermoelement is a metal product, the geometric dimensions of which decrease or increase under the influence of temperatures (depending on the degree of heating). And from this, in turn, the position of the special lever changes, which closes and opens the traction flap. The photo shows a sample of such a regulator:
Photo: sample thermostatThe 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 completely 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 set thermal conditions, control the air flow, turning on (or 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 for heating only. The connection diagram is shown in the figure below:
Single-circuit boiler connection diagram Double-circuit boilers have two heat exchangers and are designed for heating and receiving hot water. The boiler connection diagram is presented below:
Some boilers have separate regulators for heating and hot water temperatures.
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 cold water supply. Provided for temperature regulation and overheating protection.
Mechanical boiler timer Using a simple mechanical timer for an electric boiler there are three options for starting the central heating system:
Mechanical timers usually have a large, round dial with a central 24-hour scale. You can turn the dial to set the desired time and then leave it that way. The boiler will turn on at the right time. Outer part consists of a set of tabs of a 15-minute period, which are inserted for the convenience of adjusting the operation and setting the modes. An emergency readjustment is possible, which is carried out when the boiler is connected to the network.
Mechanical timers are easy to set, but at the same time 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 carried out several times a day at different times.
By the type of functions, they can be divided into several groups:
- with one function (maintaining temperature);
- with a large number of functions (programmable).
By design, thermostats are divided into types: wireless and with wires for communication with the boiler. The thermostats are installed in a convenient place, the temperature sensor is connected, connected to the boiler control system and used.
The room thermostats need a constant supply of air for normal and correct work therefore they should not be covered with curtains or blocked by furniture. Devices adjacent to an electric thermostat can interfere with the correct operation of the device: lamps, televisions, heating devices 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 time timer allows you to set a different pattern for heating on weekdays and weekends. Some timers allow you to set different parameters for each day of the week, this can be useful for people working 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 of the house at all times, 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 clock has moved forward and backward, or a certain change in climatic conditions has occurred. We also recommend changing the temperature settings when changing day and night.
Such a climate controller has several options that expand its capabilities:
Such a thermostat is located far from your boiler and usually allows you to turn heating on or off throughout the house. Older versions are wired to the boiler, newer systems usually send signals to the command post of the device. It is with devices of a new type that rather expensive but effective devices are equipped: double-circuit boilers Ferroli, Beretta and domestic AOGV.
The most famous are room thermostats for double-circuit boiler brand Gsm and Protherm. They have a built-in dilatometric thermostat for the boiler, which, depending on the model, can work remotely; this technology is often 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 on the heating when the air temperature drops below the thermostat setting, and turning it off when set temperature will be achieved.
Tips:
As a rule, only one climate microcontroller in the heating system is based on the temperature of the whole house, or individual rooms. The best option its location in the living room or bedroom, which should probably be the most visited place in the house.
Room thermostats need free air flow to measure temperature, so they should not be covered with curtains or blocked by furniture. Devices adjacent to the electrical thermostat may interfere with the correct operation of the device. These include lamps, televisions, neighborhood boilers through the wall, touch switches.
Thermostatic valve a simple solution to the problem of obtaining a heat carrier of a given temperature by mixing colder water with warmer one. The three-way valve is shown below:
The thermostatic radiator valve allows you to control the room temperature 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 to adjust the temperature that is needed in each individual room.
This idea should be considered as a complement to the thermoregulation installation. Also, such devices need periodic readjustment and regular performance checks (every six months during a change in operating modes).
Below is a diagram of a homemade boiler thermostat device, which is assembled on Atmega-8 and 566 series microcircuits, an LCD display, a photocell and several temperature sensors. Atmega-8 programmable microcircuit and is responsible for compliance with the specified parameters of the thermostat settings.
In fact, this circuit turns on or off the heating boiler when the outside temperature drops (increases) (U2 sensor), and also performs these actions when the room temperature changes (U1 sensor). Adjustment of the operation of two timers is provided, which allow you to adjust the time of these processes. A piece of a circuit with a photoresistor affects the process of turning on the boiler according to the time of day.
The U1 sensor is located directly in the room, and the U2 sensor 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 the shutdown of high-power units:
Another thermostat circuit with one control parameter based on the K561LA7 microcircuit:
The assembled thermostat based on the K651LA7 microcircuit is distinguished by its simplicity and ease of adjustment. Our thermostat is a special thermistor that significantly reduces resistance when heated. This resistor is included in the electricity voltage divider network. Resistor R2 is also located in this circuit, with which we can set the required temperature. Based on this scheme, you can make a thermostat for any boiler: Baksi, Ariston, Evp, Don.
Another circuit for a microcontroller-based thermostat:
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 reassemble and use it to your health. The device is not moody and works fine.
The cost of parts is 300-400 rubles. A similar regulator model costs five times as much.
A few final tips:
Thermostats for heating boilers: types, prices, characteristics. Given the rise in energy prices, the issue of energy conservation is extremely acute. That is why a large number of models have been developed heating appliances, economically consuming fuel. However, the equipment itself is not enough. The most efficient way to spend energy will be a thermostat for a heating boiler (thermostat), which allows you to control and maintain the set air temperature in a heated room.
The thermostat is designed to adjust optimal temperature in room
To be able to control the consumption of energy resources of heating equipment, it is equipped with special devices - thermostats. These devices allow efficient use of fuel 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.
The thermostat is able to respond to temperature changes and turn on and off the heating equipment in automatic mode
To achieve economical operation of the heating boiler, the thermostat turns on the equipment when the temperature drops below the set value and turns it 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 require less heat to heat them than 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 excessive consumption of energy resources.
With the help of the thermostat, you can set different heating modes for different times
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. A distinction is made between electromechanical and electronic thermostats. The design of a mechanical thermostat for a heating boiler has an on / off button and a rotary button for temperature control.
Electronic or programmable thermostats are more advanced in design, but simple and straightforward 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 control. 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 of 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.
The simplest type of thermostat is mechanical
The wireless boiler thermostat is controlled by radio transmission. 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 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 microcircuits, due to which the device can record and apply several preset modes. Analog thermostats are controlled manually by means of a mechanical regulator connected to a rheostat.
Before buying a thermostat for a boiler, you need to decide on the type of device. To do this, you need to figure out what is the fundamental difference between the models of room mechanical thermostats and electronic ones. It is believed that the latter are difficult to configure and unreliable, but this is not the case.
The electronic thermostat is more accurate and flexible
In most cases, mechanical thermostats 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 thermostats. The mechanical thermostat has 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 the mechanism for closing or opening the power supply system of the heating boiler 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 model of the thermostat, you can set an acceptable temperature mode by turning the round button with divisions, which is connected to the membrane. Thus, the membrane walls approach or move away to the control device: this is how we set the temperature at which the connection or contact breakage will occur.
The thermostat allows you to regulate the room temperature with an accuracy of 1 degree
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 operate. The approximate price of a room thermostat for a gas boiler is 1500 rubles.
The advantages of mechanical thermostats include low cost, the possibility of repair and resistance to voltage surges. The disadvantages include the low sensitivity of the device to temperature changes. Uncertainty can be up to 3 ° C.
The use of programmable wireless thermostats for gas boilers makes it possible not only to control the work heating devices but also do it remotely. Electronic regulation allows you to set various operating modes of the boiler, depending not only on temperature, but also on a certain time of day.
The programmable electronic thermostat allows you to set desired mode heating for a certain period of time
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 pays off within two heating seasons.
Modern models of thermostats are equipped with a GSM standard, which allows information to be transmitted 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 via the Internet. Know-how in this area is the development of special applications for a smartphone.
Convenient operation system, no need for wires, control of equipment in automatic mode are important advantages in using a wireless room thermostat for a gas boiler. Devices can be purchased with additional options, such as joint control of the gas burner unit, equipment control depending on the outside air temperature, system diagnostics and other functions.
Thermostats of the new generation allow you to control the room microclimate through special applications using your phone
Of the shortcomings of programmable room thermostats, one can perhaps 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 you buy a thermostat for a gas boiler, you need to inquire about the compatibility of the device with the model gas apparatus from a specialist of the selling company.
An excellent example for autonomous heating is the Baxi gas boiler room thermostat models. 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 a thermostat for a heating boiler Baxi model AURATON 2030 RTH - 6900 rubles.
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 making a choice between analog and digital models, the latter have a lot of advantages and, accordingly, their price is higher.
Installing a room thermostat for a gas boiler will help reduce fuel costs for heating the room
However, the use of a programmable room thermostat for a heating boiler can significantly reduce the frequency of switching on / off equipment, which has a positive effect on its operation as a whole.
Extremely important feature room thermostat for the boiler is a programming function that 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 desired parameters, taking into account the days of the week (workdays, weekends), the calendar season and other settings. This is very convenient for those who have shift work or part-time work.
The main advantages of a programmable room thermostat for a gas boiler:
The principle of operation of a room thermostat for a gas boiler
Useful advice! By purchasing a room thermostat for a programmable boiler, you get the opportunity to control heating equipment at any time of the day, regardless of your presence in the house.
After the model is selected, the question arises of 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 to the boiler will be described. additional devices and all the required schemes are given.
Wiring diagram of a room thermostat to a heating boiler
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 the heating equipment. The fixation of 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:
It is necessary to install the thermostat in an open area away from heating appliances
Useful advice! The room thermostat sensors for heating are triggered when the room temperature changes by 0.25 degrees.
You can control the operation of heating equipment using the setting in manual mode 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, the boiler will have to be reconfigured manually again.
You can control the operating modes of a gas heating boiler both manually and through a thermostat
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 with the operation of the circulating pump, regardless of which mode the unit is in: operating or waiting. This leads to rapid wear of the heating equipment 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 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 drops. Thus, if the appliance is set to 20 ° C, and during the day the room is warmed up also due to the sun's heat or the operation of cooking appliances, the boiler will be in the waiting stage for a long time.
The thermostat helps to reduce heating costs by 30-40%
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 a thermostat for a heating boiler and connect it to the 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 by means of which the setting is carried out. The switches allow you to control the heating and air conditioning of the air space, delayed switching on (prevents the boiler from starting 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 increases or decreases 0.5 degrees).
For the correct setting of the thermostat for a heating boiler, it is better to contact a specialist
Using the buttons, two modes are set: optimal 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 resources. Different models of thermostats have several preset modes, one of which can be selected for use.
Useful advice! In rooms where children and elderly people are most often found, it is recommended not to lower the temperature below 22 ° C.
In places where gas supply is not available, they use electric boilers... Among the advantages of such equipment are the absence of the need for a chimney, ease of installation, environmental friendliness, quiet operation, high performance and equipping with a control unit for automatic operation.
It is enough to install and configure the thermostat for the heating boiler and it will maintain the temperature automatically
The disadvantages of electric heating include one, but rather significant drawback - significant electricity consumption. 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.

By purchasing a thermostat for a heating boiler, you can not only adjust a comfortable temperature regime for each room in the cold season, but also extend the life of the heating equipment.
Some models of heating boilers are endowed with electronic circuits necessary to expand the functionality and more conveniently control the microclimate in the house. The equipment turns out to be complex, but pleasing with an abundance of service capabilities - from automatic temperature control in the circuits to the control of external auxiliary units. An indisputable advantage is the ability to connect additional control modules. For example, a thermostat for a heating boiler will maintain a given temperature regime and provide convenient heating control.
Owners of simple heating boilers do not have to think about the convenience of controlling the climate in the house. Most often, all adjustments on such boilers are reduced to one simple knob for selecting the degree of heating of the coolant - a simple scale with numbers from 0 to 9 is used here. In the autumn cold, the equipment operates on one or two, and in severe frosts, users set the knob to higher numbers.
Thus, the simplest thermostat is used here, focusing on the temperature of the coolant in the system. The required heating level is set manually, and then a simple thermoelement based on a bimetallic plate begins to work in the boiler - it turns on the ignition, provides gas to the burner. This scheme is used in many simple models.
More advanced boilers regulate the temperature and the degree of heating of the premises as follows:
Models with a remote sensor will regulate the temperature exactly where the sensor is installed.
Weather-dependent sensors are rarely used by consumers - people are used to relying on their own feelings. Therefore, they choose to control the heating medium temperature or control the indoor air temperature.
A remote thermostat for a boiler is an external control module installed at an arbitrary point in the household or apartment. It includes a room temperature sensor and controls. The main function of this miniature device is to track the set temperature based on the readings of the thermoelement. With a decrease in temperature, the regulator sends a command to the boiler to turn on the heating, and after reaching the set value, turns off the burner.
Thermostats for heating boilers also have additional functionality:
Thanks to the remote design, the thermostats provide the convenience of controlling the operation of the heating boiler, which can be located in any remote room - this is a kitchen, bathroom or basement.
The functionality of thermostats varies widely. The simplest modifications are a single adjustment knob with a mechanical scale. More complex devices are equipped with several regulators and electronic displays, which display various data. Accordingly, the prices for such devices are higher - they are more advanced, giving users a lot of service functions.
The thermostat for a gas boiler is a full-fledged remote control panel. Judge for yourself - if the boiler is hanging in the kitchen, then in order to lower the temperature in the heating, you will have to get up from the sofa and visit the kitchen. If a thermostat was installed in the room, it was enough to turn the knob or press the temperature lowering button. Worst of all, if the heating equipment is installed in hard to reach place- in this case, you simply cannot do without a remote control panel.
In programmable thermostats, you can set different temperature modes for day and night.
The basis of any thermostat for a heating boiler is a temperature sensor. It analyzes the air temperature in heated rooms, controlling the operation of the burner and other components. By setting the knob or buttons to +22 degrees, you can leave the equipment alone - it will itself ensure the achievement of the set temperature regime. Whatever the outside temperature, the room temperature will stay at the same mark.
A programmable room thermostat is more complicated - here we can set a specific heating program. For example, in the daytime we set +23 degrees, and at night we set +20 degrees (at a lower temperature, sleep will be stronger and healthier). We can also set the temperature in the hot water supply circuit or adjust the degree of heating of underfloor heating.
A more complex and advanced room thermostat for a gas boiler will be able to work with several heating heating circuits at once, providing separate temperature control.
A thermostat for a heating boiler is just a convenient addition that provides temperature control and management of various service functions. This device is not an obligatory unit of the heating system; in some cases, you can do without it. The room temperature regulator is convenient in large households and in multi-room apartments, when the boiler may be too far away - in this case, the temperature can be adjusted, for example, from the living room.
Let's consider all the advantages of a thermostat for a heating boiler:
Once you have set up such a device, you can enjoy a comfortable temperature in your home for a long time.
Unfortunately, there were some drawbacks:
The disadvantages are not the worst, so you can put up with them. After all, convenience comes at a price.
A room thermostat for a heating boiler is a necessary and convenient thing. But there are so many of these thermostats on sale that the eyes run wide. Let's see how these devices differ from each other and what are the features of their operation in heating systems. To begin with, let's discuss the division into electronic and mechanical models - by the way, the latter are much cheaper, but inferior in functionality.
Mechanical models are simple and reliable.
A mechanical thermostat for a heating boiler is a temperature controller with the simplest internal device. Inside we will find a simple thermocouple based on a bimetallic plate (sometimes other types of sensors are used) that control dry electrical contacts. The corresponding regulator is responsible for setting the temperature. Due to its simple design, the equipment is distinguished by its low cost.... But there is no automation here.
Please note that the thermostat for the heating boiler and the room mechanical thermostat for the heating boiler are two different devices - the first is an internal heating equipment unit.
An electronic thermostat for a heating boiler is a more advanced device. Temperature control in it is provided by an accurate electronic sensor that records temperature changes with an accuracy of tenths of a degree. The simplest modifications have a minimum set of functions - monitoring the operation of the heating circuit. More advanced models will delight you with powerful functionality:
Most of the thermostats for heating boilers on sale are represented by electronic models - "mechanics" are much less common in stores.
Wireless thermostats are very easy to install as they do not require cabling.
Thermostats for heating boilers are divided into wired and wireless. Wired models differ more affordable price... The thermostat is connected to the boiler using a two-wire cable - it is laid under plaster or laid in skirting boards or cable ducts. The optimum cross-section of each conductor is 0.75 sq. mm.
The wireless thermostat is more interesting because it doesn't require wiring. The range of this device is up to 100 meters in line of sight... In real conditions, it falls by 1.5-2 times due to the walls. Worst of all, the signal goes in apartments, where the walls are made of reinforced concrete. But there is no need to lay a connecting cable, which is important for buildings where repairs have already been made.
A typical representative of the mechanical category is the Zilon ZA-1 thermostat. This is the simplest model with a relay output, designed to work with equipment that supports a "mechanic" connection. The temperature sensor response range is from +10 to +30 degrees.
This model uses a gas-filled sensor that operates dry electrical contacts. The thermostat is not recommended for installation in rooms with high humidity.
The room thermostat for a gas boiler called Protherm Exacontrol is designed to work with heating equipment from the same brand. But it can work with any other boilers. It regulates the temperature in the range from +5 to +35 degrees, and only in the heating circuit. For the convenience of operation, the device is equipped with a liquid crystal display. The thermostat was created for those who do not need extra functionality.
Of the wireless room thermostats for heating boilers, we can single out the SALUS Controls VS20WRF model. This is a multifunctional device that can control servo drives. It provides temperature control in the range from +5 to +35 degrees, can work according to one of the programs stored in the memory, supports connection remote sensors... To control the current operating mode, the device is equipped with a large liquid crystal display.
You can buy a suitable thermostat at any store that sells heating equipment. They are represented by hundreds of modifications, both simple and more advanced. After choosing and purchasing a suitable model, you can proceed with the installation. Next, we will tell you how to connect the thermostat to the boiler - there is nothing complicated about it.
Correct installation of the thermostat in the living area.
In order to install the thermostat on the boiler, you should decide on the place of its installation. The device should not be exposed to direct sunlight, it should not be located in the area of drafts... It is also necessary to ensure that there are no heating devices nearby - otherwise it will be difficult to achieve the required temperature. A two-wire cable is laid from the thermostat to the heating boiler.
In the case of wireless equipment, it is enough to screw it to the wall in any suitable place.
Next, you need to configure the thermostat - for this you need to remove or install a jumper located on the boiler board or in some specific place. So, the unit will be able to understand that it will work with a remote thermostat. After that, we proceed to tests, checks and programming. When using a wireless model, it is paired with the boiler according to the attached instructions.
A thermal sensor for a heating boiler, which is an internal unit of heating equipment, is installed by replacing a failed sensor.
By installing an automatic thermostat, the user hopes to save energy spent on heating an apartment or private house. True, the purchase and installation of a device sometimes gives the opposite result - the consumption of gas or electricity increases. Therefore, we propose to clarify a number of points: how a room thermostat for a gas boiler works, types of temperature regulators, methods of connection and correct settings.
For a better understanding of the principle of operation of room thermostats, we first explain the operation algorithm of a hot water boiler in the basic configuration:
The scheme of operation of a heating boiler with a remote thermostat - the automation stops and starts the burner depending on the air temperature, not the coolantReference. In turbocharged wood-fired boilers, the automatic turns off the blower fan. The intake of air and the combustion process in the furnace is suspended, the unit goes into standby mode.
Without an external temperature sensor, the heater “does not see” the air temperature in the premises and stupidly heats the water up to the specified limit. Result: in the transitional autumn-spring period, the so-called cycling is observed - frequent start / stop of the burner (once every 2-3 minutes), which reduces the resource of the unit as a whole.
Now about the main thing. The remote thermostat extends the intervals between turning on / off the gas boiler, since it is guided by the temperature of the air, which cools down more slowly. The device is switched on in a break in the power supply circuit of the gas valve (on TT boilers - turbines) and the built-in pump.
Installing an automatic thermostat allows you to kill three birds with one stone:
Important note. The items listed above apply not only to. Any heat generator equipped with an electronic or electrical control unit is connected to the thermostat: solid fuel, diesel, electric boiler, and so on.
The wood-fired boiler automation unit has a thermostat connector When the room warms up to the specified temperature, the thermostat breaks the circuit, the burner and the built-in pump of the heat generator stop. The unit starts up after cooling the air by 1-2 degrees, which increases the duration of the interval between shutdown and ignition up to 15-20 minutes.
Let's note 2 significant nuances:
That is why it is important to correctly set up the connection between the boiler and the external thermostat.
For automatic regulation of the boiler combustion according to the room air temperature, 2 types of thermostats are used:
Reference. Mechanical and electronic temperature sensors are used not only for the boiler. Thermostats are successfully used in other areas of the heating system, for example, to turn off a separate radiator branch or for zone control.
The device of the simplest mechanical temperature controller The mechanical device is connected to the heat generator via a cable. Most electronic models provide wireless connectivity. According to reviews, radio-controlled thermostats are gaining wide popularity due to their ease of installation and operation. How the wireless boiler thermostat works:
Wireless thermostats consist of 2 blocks that exchange radio signals Usually, electronic models are equipped with programmers that allow you to set the boiler operation schedule for a week. The room temperature can be changed several times during the day. Individual copies are programmed for 90 days and controlled via mobile communication, for example, via SMS or the Internet application of a smartphone.
To make the right choice of a room regulator, we propose to consider the pros and cons of two types household appliances... Disadvantages of mechanical models:
Note. Judging by the reviews of real owners on the forums, the accuracy of temperature maintenance is not a critical issue and does not bother users too much. Another thing is the wires that need to be hidden under the baseboards, in the grooves of the walls, and so on.
There are also three obvious advantages of bimetallic thermostats:
The negative aspects of electronic regulators are the higher price, not always clear interface and the need for timely replacement of batteries. Cheap Chinese models have an additional problem - communication failure with the relay unit when the control panel is installed behind 1-2 partitions.
An unconditional plus of digital thermostats is comfortable operation. It is enough to lay down the weekly and daily program of the heat generator once, no more action is required.
In wireless programmers, you need to change the batteries on time Let's list a typical set of functions using an example thermostat Baxi Magic Plus:
Reference. Manufacturers often refer to such devices as digital chronothermostats. The weak point of the devices is their low maintainability in the event of a breakdown, especially for Chinese products, for which it is not easy to find spare parts.
Knowing the features of electronic and mechanical regulators, it is not difficult to choose the right model. Focusing on your budget, first of all consider reliable products from European, Japanese and Korean manufacturers. Among the "Chinese" there are also decent brands, but on average the quality of the products leaves much to be desired.
Installation of a household regulator consists of two stages - fastening in a convenient place and connecting to a gas (solid fuel) boiler. In order for the thermostat to record the temperature without deviations, position the regulating element according to the recommendations:
Advice. For a private house with underfloor heating, it is worth buying a thermostat model equipped with an additional temperature sensor. The latter is placed above the floor surface and measures the temperature in the lower area of the room.
After fixing the appliance to the wall according to the manufacturer's instructions, lay the cable to the heat source hidden or open way(if there is a wired connection). How to connect the regulator to the boiler:
Advice. If on the contacts of your device instead of the indicated marking there are numbers or incomprehensible letters, find the 2 necessary terminals using a tester (the circuit between them must be open). There are three contacts in total, the COM and NC pair are initially closed, as shown in the diagram above.
Details of installing a wireless thermostat are shown in the video:
Non-volatile floor standing boilers equipped with 630 SIT, 710 MiniSIT, SABK, Orion and the like are incompatible with remote controls. The reason is the completely mechanical design of the gas valve and the absence of electrical circuits where a relay-breaker can be connected.
Connection diagram of the regulator to the SIT 820 NOVA valve The exception is gas heat generators equipped with Kare automatics and the latest generation of Italian valves EuroSIT - 820 NOVA. These blocks are provided with solenoid valves and special contacts for connecting external thermostats of two types - mechanical and digital.
A solenoid valve is used in the "Kare" automatics, where the thermostat is connected. To set up the system and select a comfortable temperature, follow these steps:
An important clarification. The gas boiler operates at maximum efficiency at temperature conditions 80/60 ° С (supply / return).
Let's explain the purpose of the listed manipulations. Due to different areas and heat losses, the temperature in the rooms can differ by 1-3 degrees, so it is better to navigate by the degree of heating of the air near the sensor itself.
If the temperature at the point of installation of the regulator is very different from the rest of the rooms, when adjusting, you need to make an adjustment for the value of this difference. Some models, for example, Baxi Magic Plus, provide a function for such a correction (called temperature shift). Then it remains only to enter the required value into the device's memory, ranging from 1 to 5 degrees.
There are many reviews of this kind on the Internet: “I took the sellers' assurances about saving 30%, bought and installed a temperature regulator, now the boiler consumes more gas. Why is he needed at all? " Let's see how this device saves energy resources (not only gas, but also solid fuel, diesel fuel and electricity):
Explanation. Reasonably acceptable is the temperature at which the boiler will quickly warm up the rooms to a comfortable level without much energy consumption. Determined empirically and lies within 15-18 degrees.
Now let us consider situations when, instead of saving, there is an increased consumption or deterioration in heating:
Each thermostat has a temperature difference between turning off and turning on the boiler. The value can be changed within 0.5-2 degrees. If the maximum hysteresis is selected, and the house is heated with underfloor heating, the temperature difference in the air will increase greatly, staying in the room will become uncomfortable, and the heat generator will consume more fuel for heating.
The master installer will tell you about the intricacies of setting the thermostat in the video:
According to the assurances of sellers, thermostats for gas boilers reduce the consumption of blue fuel by 25-50%. The figures are somewhat overestimated in order to sell heating equipment to the user. In practice, the amount of savings falls within the range of 10-25%, depending on many conditions. But with the current tariffs and energy prices, 10 percent will have a tangible effect, therefore thermostats are definitely recommended for use.
