Thermostat for radiator. Installation of thermostats for radiators

The thermostat on the radiator isa device that regulates the temperature and creates an optimal microclimate in the room. Often in winter, you can see an open wide open window or balcony door. This phenomenon is a simple explanation. Residents of apartments are not able to regulate the heat transfer of heating devices on their own, therefore they are forced to start cold air from the street. In order not to worry about daily airing in order to maintain the optimum temperature balance, thermostats for heating devices have been created.

Manual regulator

The principle of operation of this device is based onmanual temperature control. For this, it is necessary to turn the handwheel of the valve by itself, thereby actuating the valve stem. Worth this device is relatively inexpensive, but some of its drawbacks in choosing a thermoregulator make you think. Because of frequent scrolling, the protective cap very often breaks.

Automatic thermostat

The thermostatic cock on the radiatortype is installed to perform automatic control of the required temperature. It can record a small temperature change of several degrees. The principle of operation of this device is based on its expansion and narrowing.

If the temperature in the heater is lower thanof the permissible value, the thermostat on the heat sink is retracted, thereby allowing a larger volume of coolant to be supplied, and when the device is raised, the unit protrudes and the amount of liquid passed is reduced.

Disadvantages of mechanical controllers

Naturally, you can adjust the temperatureradiators by means of a mechanical thermoregulator, which is a classical shut-off and control valve. However, this is not only unnecessary costs, risk of zvozvushivaniya and overlapping of the entire riser, but also a high probability of regular breakage of locking devices that are unable to withstand frequent closing and opening.

In addition, with the help of an ordinary crane, it is absolutely impossible to precisely control the temperature to which the heater is heated, and with it the air in the room.

Advantages of temperature controllers

Installation of thermostats for radiatorswill easily get rid of all the above inconveniences and without much effort create a comfortable microclimate in your apartment or house, and in each room - according to your program.

Mechanical or electronic thermostatIt is indispensable for heating appliances in the kitchen, in rooms with window openings facing the sunny side, as when organizing the heating system in these rooms it is necessary to take into account the temperature fluctuations both in the daytime (additional heating of the sun) and in the night. Very sensitive to such changes is the installed electric thermostat on the radiator, which is a direct way to save energy resources and, accordingly, financial resources.

Single-pipe heating system

A single-pipe heating system means a series connection of heating devices, and the disconnection of even one of them leads to a disruption in the circulation of the coolant.

For this reason, when replacing old batteries with amodern appliances, as well as in new buildings where the radiators can be disconnected by means of ball valves, a bypass is installed in front of the valve - the pipeline connecting the supply and return pipes of the coolant. Thus, when the radiator is turned off, the circulation will not be disturbed, and your neighbors will not stay with the cold heaters.

Naturally, for such a heating systemrequires a thermostat on the radiator with little hydraulic resistance. If a regulating armature with a small internal diameter (high resistance) is placed on the supply line, a large volume of coolant will pass through the bypass, and the radiators will remain cold at the same time.

Two-pipe system

In two-pipe heating systems, radiatorsconnected in parallel, and disabling one device in no way will affect the overall performance. In this case, the bypass is not used, therefore, to effectively control the temperature, a different type of thermostats having a higher hydraulic resistance should be used.

Mounting recommendations

Thermostat for heating radiator - installation instructions:

1. The distance from the thermoregulator to the floor construction is at least 800 mm.
2. The device must be protected from direct sunlight.
3. An electronic thermostat is highly undesirable to locate in the zone of ascending air currents from radiators.
4. The remote sensor must be rigidly fixed with brackets on the wall.
5. Heat flows in the room should have free access to the regulator, in other words, it can not be covered with furniture, screen, curtains, etc.

Installation of temperature controllers

After being dismantled with the installation site, you should consider how to install the thermostats on radiators.

1. This device must be installed with regard todirection of flow of fluid. On each thermoregulator it is possible to find the arrow, its direction must coincide with the flow direction of the coolant. Accordingly, it must be mounted only in this position.
2. Another important point is the situationthermal heads. It should be mounted parallel to the floor in a horizontal position. If the thermal head is installed in a vertical position, like a conventional valve or a faucet with a flywheel pointed upwards, a warm airflow from the valve body and from the return line will prevent the unit from accurately reacting to temperature changes in the ambient air.

It is also worth paying attention to the fact thatThermostat for the cast-iron radiator should not be used due to inefficiency. The fact is that the work of heating devices from cast iron is inertial, after blocking the flow of water they continue to radiate heat for a long time.

Customize

The thermostat must be calibratedonly after the installation and filling of the heating system have been completed. It is important that the radiators are evenly warmed up. After that you can proceed with the adjustment of the thermostat. It is necessary to follow the operating instructions clearly and choose the temperature mode that is required for a particular room for the radiator.

How to adjust the thermostat on a radiator:

1. First of all, it is necessary to minimize heat loss, for this, all windows and doors are closed.
2. The head of the regulator rotates to the left until it stops, thus opening the valve completely.
3. Under the influence of the incoming hot coolant the radiator starts to heat up. As soon as the temperature is 5-6 ° C higher, the thermal head rotates to the right as far as the stop, the valve closes.
4. Gradually the air will begin to cool down. Then the head turns smoothly to the left.
5. As soon as sharp heat begins to be felt and inthe heating device will hear the sound of water, it is necessary to lower the thermal head. Remember the resulting value on a graduated scale located on the body. At this, the thermostat setting can be considered complete.
