The temperature regulator on the heating radiator is a device that carries out temperature control and creates the optimal microclimate in the room. Often in winter you can see an open wide window or a balcony door. There is a simple explanation for this phenomenon. Residents of apartments are not able to independently regulate the heat transfer of heating devices, so they are forced to start cold air from the street. In order not to worry about daily ventilation in order to maintain optimal temperature balance, temperature regulators for heating appliances have been created.
Manual adjuster
The principle of operation of this device is based on manual temperature control. To do this, turn the valve handwheel on its own, thereby actuating the valve stem. This device is relatively inexpensive, but some of its shortcomings when choosing a thermostat make you think. Due to frequent scrolling, the protective cap breaks very often.
Automatic temperature controller
A faucet thermostat on a heating radiator of this type is installed to automatically control the required temperature. It can record a slight temperature change of several degrees. The principle of operation of this device is based on its expansion and contraction.
If the temperature in the heating device is lower than the permissible value, then the thermostat is drawn into the heating radiator, thereby allowing a larger volume of coolant to be supplied, and when the temperature rises, the device protrudes and the amount of liquid passed through is reduced.
Disadvantages of mechanical regulators
Naturally, it is possible to regulate the temperature of the radiators by means of a mechanical thermostat, which is a classic shut-off and control valve. However, this is not only unnecessary costs, the risk of airing and blocking the entire riser, but also the greater likelihood of regular breakdowns of locking devices that cannot withstand frequent closing and opening.
In addition, using a conventional faucet, it is absolutely impossible to precisely control what temperature the heater is heating to, and with it the air in the room.
The benefits of temperature controllers
Installing temperature controllers on heating radiators will make it easy to get rid of all the above-mentioned inconveniences and without much effort to create a comfortable microclimate in your apartment or house, and in each room - according to your own program.
A mechanical or electronic temperature regulator is indispensable for heating appliances in the kitchen, in rooms with window openings facing the sunny side, since when organizing the heating system in these rooms, it is necessary to take into account temperature fluctuations both in the daytime (additional solar heating) and at night. The installed electric temperature regulator on the heating radiator feels such changes very subtly, and this is a direct way to save energy resources, and, accordingly, financial means.
Single pipe heating system
A single-pipe heating system involves the serial connection of heating devices, and turning off even one of them leads to a disruption in the circulation of the coolant.
For this reason, when replacing old batteries with modern appliances, as well as in new buildings where it is possible to turn off radiators by means of ball valves, a bypass is installed in front of the fittings - a 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 cold radiators.
Naturally, such a heating system requires a temperature regulator on a heating radiator with a small hydraulic resistance. If control valves with a small internal diameter (high resistance) are placed on the supply line, a large volume of heat transfer fluid will pass through the bypass, while the radiators will remain cold.
Double pipe system
In two-pipe heating systems, radiators are connected in parallel, and turning off one device will in no way affect the operation as a whole. In this case, the bypass is not used, therefore, for the effective temperature control, another type of thermostats with a higher hydraulic resistance should be used.
Installation Recommendations
Thermostat for a radiator - installation instructions:
- The distance from the thermostat to the floor structure is at least 800 mm.
- The device must be protected from direct sunlight.
- It is extremely undesirable to place an electronic temperature controller in the zone of ascending air flows from radiators.
- The remote sensor must be firmly fixed with brackets on the wall.
- The heat fluxes in the room should have free access to the controller, in other words, it should not be covered with furniture, a screen, curtains, etc.
Installation of temperature controllers
After you have figured out the installation site, you should consider how the thermostats should be installed on heating radiators.
- This device must be installed taking into account the direction of the fluid flow. An arrow can be found on each temperature controller; its direction should coincide with the direction of the heat carrier flow. Accordingly, it must be mounted only in this position.
- Another important point is the position of the thermal head. It should be mounted parallel to the floor in a horizontal position. If the thermal head is installed in an upright position, like a regular valve or valve with the flywheel pointing upward, the warm air flow from the valve body and from the return pipe will prevent the device from responding accurately to temperature changes in the surrounding air.
It is also worth paying attention to the fact that the temperature regulator for a cast-iron heating radiator should not be used due to inefficiency. The fact is that the operation of cast iron heaters is inertia, after blocking the water flow, they radiate heat for a long time.
Customization
Calibration of the thermostat should only be carried out after installation and filling of the heating system are completed. It is important that the radiators are evenly warmed up. After that, you can begin to configure the thermostat. It is necessary to strictly adhere to the operating instructions and select the temperature mode for the radiator that is required for a particular room.
How to set the thermostat on a heating radiator:
- First of all, it is necessary to minimize heat loss, for this, all windows and doors are closed.
- The regulator head rotates all the way to the left, thus completely opening the valve.
- Under the influence of the incoming hot coolant, the radiator begins to heat up. As soon as the temperature rises by 5-6 ° C, the thermal head rotates all the way to the right, the valve closes.
- Gradually, the air will begin to cool. Then the head smoothly turns to the left.
- As soon as sharp heating begins to be felt and the sound of water is heard in the heater, it is necessary to lower the thermal head. Remember the resulting value on a graduated scale located on the body. On this, the temperature control setting can be considered completed.
