Gas boilers are usually equipped with the simplest system regulation of heating of the heat carrier. The user sets the temperature parameters using a mechanical, less often an electronic controller.
Sensors that control the heating of the liquid in the heating system, giving a signal to the automation that turns off and on the gas supply. Such a device is ineffective, since it does not take into account the heating temperature of heated rooms.
Room thermostat for gas boiler, designed for precise adjustment. Installing the sensor reduces fuel costs by 15-20%.
Turn on the boiler, remove the protective plastic film from the screen and follow the steps to follow automatically. All your settings, time programs are saved even during a power failure. Right time etc. will be displayed as usual.
The screen automatically turns on when an object or person moves within a radius of 0.5 to 1 m in front. If a person or object remains within range, the screen will automatically turn off after 5 minutes. When your smartphone reinitializes after a reboot, you will need to enter a new passcode for all apps, and any new devices connected later will require a passcode.
Why you need a remote thermostat
First of all, it is necessary to install a thermostat due to an increase in the efficiency of a gas boiler. The principle of operation of the device is based on reading not the temperature of the coolant, but the intensity of heating the room. The sensor is adjusted to the optimal temperature parameter for the owners of the apartment or house.If the heating in the room exceeds the set limit, a signal is given to the automation, turning off or reducing the intensity of combustion (depending on the device) gas burner. After the room has cooled down, a second signal is given to resume the operation of the boiler.
You can change or view your heating schedule program with your smartphone or tablet in the app. Go to the home screen and press the soft symbol at the bottom of the screen, this will allow you to access the Weekly Preview. From there, you can see or change your program by clicking on the desired day.
This means that you do not need to change the time and that the clock automatically switches to the correct daylight savings or winter time, and your smartphone's time will be used. In the same way, you can change the time. Boiler central heating modulated. The boiler can be operated at low load for maximum efficiency.
The remote thermostat device is more efficient than the heating sensor built into the heat generator.
In addition to cost-effectiveness, installing a thermostat provides the following advantages:
- Comfortable space heating - the set temperature is maintained in the rooms in automatic mode. The device operates according to the temperature environment by independently changing the intensity of heating. As a result of the changes, a constant temperature is maintained in the rooms.
- Autonomous operation - after installing the thermostat, there is no need for constant monitoring of the gas boiler. The sensor will independently select the most optimal and economical mode. If a daily and weekly programmer is connected, it is possible to program the sensor for each day of the week, by the hour.
Is it profitable to install a thermostat when heating from a gas boiler
Connecting a room thermostat to a gas boiler reduces gas consumption by 15-20%. Weekly weather-dependent programmer reduces gas costs by another 5-10%.When deciding whether to purchase a thermostat, you need to consider several points:
It is more economical to leave the boiler than to turn it on and off every time. The motion sensor on the screen reacts to anything within a radius of 0.5 to 1 meter. Right place installation is described in the instruction manual. In manual mode, you do not need a smartphone, and when resetting all data, the factory settings are lost and restored, the first time you connect the device after the reset, you will need to enter a new password. submit an application. You will need serial number and access code. Any new smartphone or tablet connected later will.
When all application users are present, the default temperature is the highest that can be reset manually. Yes, the outside temperature is displayed by default on the main screen. That's why the setup wizard asks for your location information.
- The cost of purchase and installation - the cost of purchasing a premium sensor will be about 5 thousand rubles. Installation will cost within 1-1.5 thousand rubles.
- The efficiency of the boiler operation when installing a remote thermostat reaches 30%. With an average gas consumption of 400 m³ per month for heating a room of 100 m², the savings will be 120 m³. Considering that the average price for gas is within 6 rubles/m³, each month it will be possible to reduce costs by 720 rubles.
The principle of operation of the gas boiler thermostat
The relatively simple principle of operation of a room thermostat for a gas boiler is efficient and economical. Gas boiler automation uses indirect heating control in rooms.Inside the heater is installed, with a metal insert that reacts to heating. When the coolant reaches the set heating temperature, the needle-rod of the thermostat expands and closes the gas supply valve. After cooling of the liquid passing through the boiler circuit, the insert returns to its original dimensions. The gas valve opens again, the burner starts.
Therefore, it is not necessary to install an external sensor on the central heating boiler. The displayed gas consumption is the fuel consumption of the boiler. The total gas consumption may be higher as other appliances may run on gas in the home. The gas meter shows the total gas consumption for the entire dwelling.
Turn off the preheating of your boiler or select a page hot water application in the "User Program" and delete all hot water settings. Lower energy bill? If you save on heating, you won't necessarily feel the difference at home, but you will quickly feel it in your wallet!
The operation of a gas boiler when using a room thermostat has a similar principle and some significant differences:
- The temperature-sensitive element is installed not in the boiler, but in the remote thermostat unit. In premium models, this function is performed by an electronic microsensor.
- When the set temperature is reached, the module closes the electrical network, acting on the contacts.
- After the electrical network is closed, the device on the boiler itself is activated - combined gas valve or controller. The signal puts the modulating burner into reduced power mode, the classic burner device is completely switched off.
- After the temperature in the room drops to the lower limits set in the thermostat, electrical network opens, the burner starts up again.
Not all gas heating boilers are available with the ability to connect a room thermostat. In some models, it will be necessary to completely replace the automation and the gas valve.
Adjust the room thermostat optimally
Your thermostat determines the temperature of the room it is in. It then passes this information on to the boiler, which then automatically starts or stops.
The best place for your room thermostat
1.5 meters above the floor Not too cool, so not near the front door or outer wall. Otherwise, your thermostat will record more than low temperature than the rest of the room and starts your boiler too quickly. Not too hot, so not near a heat source such as a lamp or TV, or in direct sunlight. Your thermostat would then record a higher temperature than the rest of the room and start your boiler faster.Let Your Thermostat Keep Your Daily Rhythm
With certain thermostats it is possible to set the desired temperature on each day of the day.Choosing a thermostat for a gas heating boiler
When choosing a thermostat for a gas boiler, several characteristics are taken into account:- Type of connection to the boiler automation - for uninterrupted operation, it is necessary that the remote module is in close contact with the control device that affects the operation of the burner. There are two main design solutions to the issue:
- The wired thermostat is connected directly to the boiler. The connection is made using wires, which is not always convenient.
- Modern modules mainly use wireless remote connection.
- Regulator type:
- Mechanical thermostats regulate the operation using a temperature-sensitive element, which gives an error of several degrees.
- Electronic modules more accurately regulate heating, but are more expensive. The error is no more than 1%.
- Type of control - the operating mode is set by a mechanical regulator or by pressing the buttons on the panel. Convenient to use remote thermostat remote control a gas boiler that allows you to adjust the operating parameters without "getting up from the sofa" using the remote control.
Room thermostat with weather regulation – optimal effective solution boiler adjustment issue. The module belongs to the premium class equipment and provides accurate selection and maintenance temperature regime, depending on weather conditions.
Reduce by one degree and save 7%
- At that time you go to work.
- At that time you go home.
Install thermostat on radiators
Your thermostat is located in a room - often the living room - and controls the heating system. With thermostatic valves on the radiators, you can also set the temperature accurately in other rooms. The thermostatic valve is equipped with a sensor to measure the room temperature. Is it below the set temperature? In this case, the valve increases the flow of hot water in the radiator until the desired temperature is reached.
To take parameters indoors and outdoors, the thermostat comes with additional sensors. The controller takes into account the totality of data and independently selects optimal mode heating.
Selection of thermostat by manufacturer
Control valves are manufactured by several leading European manufacturers. The rating of the best includes 11 companies that produce models of thermostats that are most popular with the Russian consumer:- Cewal RQ is a room thermostat with mechanical control and regulator.

How to install a room thermostat for a gas boiler
Installation of remote room temperature sensors takes place in several stages. Setting up a wireless programmable electronic thermostat for a gas boiler, due to complex settings and connections, it is better to entrust it to a professional. But the installation of a mechanical module, it is quite possible to do it yourself.For installation you will need:
Lower the blinds and close the draperies
There is an alternative: a moving room thermostat. Your hot water pipes lose a lot of heat. Leave your boiler and pack your pipes well. A simple intervention that allows you to make good savings! It's time to lower the shutters and close your draperies. This is not only more pleasant, but also saves 5% of energy. Indeed, windows - double glazed or not - let the cold in. You feel cold and therefore easily increase the heat by one degree. So quickly close your hangers!
- Choose a place - the sensor is installed on an interior wall partition, approximately 1.5 m from the floor. It is not recommended to install the module on a wall facing the street.
The installation site should not be blocked by furniture, covered with curtains. The sensor must not be placed near heating appliances. All this affects the distortion in the work.
Remote room thermostat for a gas boiler, installed at a distance of up to 10-20 m from the boiler (indicated in the instruction manual). Wired module, usually limited to 3-7m. - Connect - installation is carried out strictly according to the instructions supplied by the manufacturer for each module. The device is connected to the boiler using a terminal or wires.
- Configure thermostat - set the operating parameters for turning the device on and off. The first start, again, is described in detail in the instruction manual. The fact that the device is properly connected is indicated by a lit indicator.
To check the operation of the thermostat, set the auto mode. At the same time, the temperature in the room will reach 18°C, after which the boiler will turn off. After testing, the required heating intensity in the room is set.
Achieving a comfortable temperature in the house, we manually control the operation of the gas boiler. This regulation is very relative, since we set the temperature of the coolant on the boiler. Costs weather conditions change in one direction or another, as the temperature in the rooms decreases or rises, it is necessary to again regulate the heating of the coolant on the boiler. This applies to all gas water heaters, even expensive ones. high level automation. You can get rid of the daily running around to the boiler room if you install a remote thermostat for a gas boiler. Some manufacturers of boiler equipment supply it with their products as an option.
In addition, you prevent drafts through cracks and grooves. Note: Make sure the hanger is not hanging in front of the radiator. The heat will then remain trapped between the draperies and the window and will eventually be lost. Dry air is much more efficient at heating than moist air. Therefore, it is important that the parts you heat up are well ventilated. New designs are often provided with very good ventilation system, but in old houses it is necessary to properly ventilate the rooms. So open your windows and doors fully.
How it works?
In a standard situation, the boiler installation heats the water to the set temperature and does not react in any way to the fact that the house becomes hot or cold after a change in the weather. Even daily fluctuations in street temperature make themselves felt. The regulation of the gas boiler according to the heat carrier is indirect, in order for the regulation to be direct, it must be carried out according to the air temperature in the premises. For small one-story houses it is enough to install one room thermostat in the passage room to solve the problem.
Consider energy consumption
30 minutes a day is enough. If you write down your meter readings every week, you won't have any nasty surprises. Also follow usual advice on energy saving. Effective thermoregulation allows you to optimize the heating system, regulate the operation of the boiler and adapt the requirements to home comfort to the outside temperature. Thus, all elements of the heating system work in teams, providing greater efficiency and subsequent economic and economic savings.
The simplest thermostat consists of a sensitive element, which is an actuator, and a contact group with a regulator. The thermoelement is a closed capsule (bellows), most often a mixture of gases is pumped into it, less often a liquid. The bottom line is that this placeholder is sensitive to changes in ambient temperature. When it rises gas mixture expands, stretches the bellows and moves the stem that closes the contacts. A decrease in temperature causes the reverse process and the contacts open.
Are you looking for another solution, for example installed directly in the boiler? Each remote control solution comes with a dedicated app that allows you to access key functions and information about your heating system. They cost little and promise great savings, but boiler owners don't believe them and consider them technical buffalo. Try asking someone who is one of the boilers that have installed smart thermostats controlled by smartphones throughout their lives: "Useless things", "Spilled money" and "They burst right away" are some of the possible answers.
The task and principle of operation of the thermostat of a gas boiler is to stop heating the coolant at the moment the required room temperature is reached, and after it drops to the lower value, resume work. In the simplest scheme, the thermostat closes two contacts, the wires from which are laid to the heating installation and connected to the electromagnetic gas valve.
If they are right, the companies or those who end up boiling our hands every day will only say bills at the end of the year, but the spread of these products also in Italy has prompted us to make this a little deepening, trying to say what are the benefits various models and why, according to the company, you can achieve noticeable results with a smart thermostat. Decided to try them individually for next winter, including the famous nest, as you will read, it can also be installed in Italy.
The thermostat is one of the most technologically "simple" objects that can exist: a clock, a thermometer and a switch cause the boiler to turn on in a given time zone if the temperature is below the user-set one. Of course, for those who have self-heating and therefore have a thermostat capable of regulating the ignition or shutdown of the boiler.
In the working position, the latter is constantly open, when the thermostat contacts are closed, voltage is applied to the valve and it closes the fuel path of the main burner, the flame remains only on the igniter. After the room temperature has decreased, the voltage is removed from the valve, it opens gas line and the burner is ignited by the igniter. With this scheme of operation, the thermostat is connected to a gas boiler as shown in the figure.
The rule that all boiler installers advise to follow is simple: avoid continuous ignition and shutdown, but keep the standard temperature around 20 °, increasing it only in time intervals where necessary, but not too much. Thus, the operation of the boiler, at least, makes it much larger than the boiler operating at high temperatures. A chronothermostat, that's the correct name, is nothing more than a switch set by two parameters, a trivial switch that "lights up" or "turns off" the boiler.
How to connect a thermostat to a boiler
Types of remote thermostats
To maintain the required temperature in the premises, the following regulators are used:
- A simple thermostat with a manual temperature gauge and a wired connection. Complete with wires up to 30 m long.
- Controller with display and programming capability, complete with wires for connection.
- The same, with a built-in GSM - a module for communication with a mobile phone.
- Autonomous wireless controller.
- An external wireless thermostat for a gas boiler that allows you to control its operation depending on weather conditions.
The last type of thermostat is used in conjunction with an electronic control unit for a heating installation that has this function. Most of the leading foreign manufacturers provide for this possibility in their products. The weather-dependent regulator is connected to special contacts of the controller or communicates with it via a radio module. This method of regulation is considered the most effective, since the boiler installation responds to cooling (or warming) even before the cold penetrates the house and the temperature in the rooms begins to drop.
Smart thermostats, as far as they can be connected to the cloud, calibrated to the use and use of users and technologically advanced, cannot escape this banal rule: the only command they can give to the boiler is "off". How do they then create savings?
Tado promises 25% savings, up to 300 euros per year
All this adds compensation based on the weather, which is always pulled from the web. Often and willingly, the programming of the thermostat is "standard" and unresponsive to events, Tado can know if the family is out one night or by accident, and he stays at home all day. 
Tado can be bought or hired for 08 euros per month. Manufacturers are so confident in the savings they offer that until recently they offered to compensate for the "savings".
You can set the required temperature in the house if you put a programmable thermostat for the boiler with a display. Depending on the manufacturer, the instrument electronics can be programmed a week or more in advance to different time the required temperature was maintained in the house for days. The function makes it possible to save fuel, since it makes no sense to fully heat the house when there is no one in it. The same applies to the night time, during sleep, the temperature can be lowered by several degrees, and raised again in the morning.
Nest, the most beautiful to see, learn habits
We have e-ink net display and remote control
Save yourself because you know where you are wrong. From a practical standpoint, the smart thermostat and programmable thermostat do the same thing, but the smart thermostat definitely has more arrows on the dome. First of all, it allows remote control, and it can be useful if you forget to turn the heating on or off, but above all, it allows for more subtle and dynamic programming than usual, with a normal thermostat programmed, perhaps the beginning of winter, and then rarely touched.
A thermostat with a GSM module can send information to your phone using text messages. AT gas boilers Wi-Fi modules are installed by leading European and South Korean manufacturers, with which you can control the operation of the unit via the Internet. Since the controller of such heating installations is connected to the room thermostat, it is possible to remotely change the temperature in the premises of the house through the network.
There is a novelty in the boiler equipment of some leading manufacturers. For remote control of all functions of the unit, special applications have been developed that are installed on a smartphone.
Wireless thermostats for boilers are equipped with a built-in radio module for communication with the boiler controller. Ease of use and the absence of long wires are the main advantages of these devices. The disadvantage is that heating units and thermostats from different manufacturers may not be compatible with each other. The regulators connected to the boilers with wires also suffer from the same drawback. The problem arose due to the abundance of various manufacturers of electronics and gas equipment. For this reason, it is necessary to buy the device after consulting with a specialist in the service department of the company - the manufacturer of the boiler and thermostat.
Various additional automation for gas boilers, including thermostats, have an increasing number of functions, their range is constantly expanding. Some models with a large LCD display can not only maintain the temperature in the room, but also control gas burner device together with the electronic unit of the boiler. On the display, you can see the values of the temperature of the coolant and the outside air, and in the event of an emergency or minor malfunction, an error code will appear on the screen. These electronic devices eliminate the need to frequently visit the furnace room in order to check the operation of the equipment.
Conclusion
The cost of thermostats cannot be called high, but with their help you can significantly save any fuel that is used in your boiler room to heat your home. At the same time, there is an additional convenience in the operation of the entire heating system.
