Room thermostat (temperature controller) for gas boiler

A device that regulates the operation of a gas boiler, focusing not on the temperature of the coolant in the boiler, but on the air temperature in the room - this is the temperature controller for the heating boiler. That is, this is an apparatus that provides not only control of the process of heating water with a gas boiler, but control of the process of heating it based on the final result.

Why buy a thermostat

When the operation of the gas boiler is adjusted manually, the equipment is forced to operate in a mode that involves constant short-term switching on and off. In this case, the start of water heating is performed for a short time - no more than 10 minutes. The constant circulation of water in the system is provided by pumping equipment, which operates regardless of the state of the heating elements.

Such an organization of the operation of the climate system is fraught with a significant consumption of electrical energy. In addition, this mode leads to rapid wear of all boiler systems. Therefore, it is not at all surprising that room thermostats have gained such popularity all over the world. In some Western countries, their installation is even considered mandatory. Since if the house is heated with a gas boiler, the presence of a “home controller” significantly reduces the cost of gas and electricity, and also helps to use expensive equipment more carefully.

The thermostat for the boiler has a certain response threshold (on average, about 0.2 ° C), when the air temperature drops or rises relative to the set parameters, it either turns on or off the boiler and the pump. Such a system guarantees the owner of the thermostat a number of advantages:

  • fully provides control over maintaining the required temperature in the home, which means that even on days of sharp temperature fluctuations outside the window, in a house where the thermostat works, coziness and comfort will always reign;
  • with the advent of this equipment, the owners of a house or apartment immediately have at least one less problem: not only the “weather in the house”, but also the level of operation and health of the boiler will now be monitored by this small device;
  • due to significant savings in fuel and electricity, the cost of purchasing the device pays off within a few months.

What are thermostats

Currently, the choice of thermostats is large, while they may vary depending on:

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

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

The scope of possibilities of thermostats can be different. Less expensive - simple, reliable and durable wired thermostats do an excellent job with the list of basic functions, steadily maintaining the level of set temperatures in the room (usually in the range of 10-30 ° C), but only in one mode. In addition, the operation of the device does not affect the level of fuel consumption by the boiler.

A completely different matter is a wireless programmable room thermostat for a gas boiler.

By purchasing such a device, you can use the features:

  • remotely monitor and control the operation of the boiler;
  • installation and configuration of various operating modes of heating equipment depending on the day of the week or time of day;
  • control over fuel consumption and serviceability of gas heating boiler systems.

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

Connecting wireless option

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

  • block for installation near a gas boiler (by connecting to a controller or gas valve);
  • block with a set of control buttons and a display - designed for installation in a room from where it is planned to control the air temperature in a house or apartment.

Moreover, the connection of the thermostat to the boiler is carried out using the terminals, and the transfer of information from one unit to another is due to the use of a radio channel. Perhaps the only disadvantage of wireless models is their dependence on rechargeable batteries, which often need to be recharged or replaced. At the same time, the device itself informs the owner about the battery level, which, of course, is a plus.

Where to put the wires

The situation is much more serious when installing wired models. And although Experts recommend combining this procedure with repair work, since the wiring will most likely either have to be masked or laid in the body of the wall into the channel formed after it has been shredded.

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

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

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

About the mechanical thermostat

An important point, those who have chosen a more durable and reliable mechanical thermostat for their home, should remember that this device does not need to be connected to the mains and batteries. However, in the course of work on its connection, it will also not be possible to avoid fiddling with wires. But in this case, we are talking about wires that provide communication between the device and controlled climate technology.

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

About the specifics of the setting

After you have successfully connected new equipment, you need to configure it, during which you can set the desired parameters, including the ability to:

  • Heating, and in some cases, air conditioning in the room;
  • Determination of the optimal delay period for the operation of the thermostat sensors (a window open for a short time or, conversely, the heat flow from the switched on hair dryer can “mislead” the device’s sensors, but turning on the response delay function will avoid errors;
  • Setting the temperature fluctuation step. That is, choosing a step of 1 degree means that the thermostat will turn the boiler on or off when the air temperature changes by 1 o C.
  • Determination of maximum comfortable temperatures. Some devices allow you to program the temperature regime depending on the time of day or day of the week (for example, on weekdays, when there is no one at home, you can lower the air temperature by several degrees, providing fuel savings, a couple of hours before the return of the inhabitants of the house, the device will turn on, adjust the temperature, ensuring its increase to a comfortable level).

About compatibility issues

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

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

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

TOP thermostats 2017–2018

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

Bosch

At the same time, the company believes that the best thermostat for a Bosch gas boiler is, of course, Bosch. And, although there is so much information on the network about the successful symbiosis of the climate equipment of this manufacturer with thermostats from other companies. However, for example, the Bosch software digital thermostat definitely deserves attention. The model is equipped with a digital display, has a temperature sensor calibration, has backup power options. The appliance can adjust the room temperature according to the time of day and the days of the week.

Protherm

This company also recommends connecting the thermostat to the Proterm gas boiler only when using "native" models. There are a number of reasons for this. For example, thanks to a special eBus switching bus, the temperature controller can control the modulation of a gas burner. Thermostats from other manufacturers cannot be connected in this way to the Proterm boiler. In addition, on the display of some models from Protherm, you can see not only the set operating modes of the boiler, but also the error codes that occur. In addition, the system, if necessary, is able to restart the boiler itself. In this way, the temperature of the boiler is regulated.
