The thermostat for a heating radiator is a device that regulates the temperature and creates an optimal microclimate in the room. Often in winter you can see an open window or balcony door. There is a simple explanation for this phenomenon. Residents of apartments are unable to regulate the heat output of heating devices on their own, so they are forced to start cold air from the street. In order not to worry about daily ventilation in order to maintain an optimal temperature balance, thermostats for heating appliances have been created.
Manual controller
The principle of operation of this device is based on manual temperature control. To do this, you will need to turn the valve flywheel yourself, thereby activating the valve stem. Coststhis 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 thermostat
A thermostatic valve on a heating radiator of this type is installed to automatically control the required temperature. It can detect a slight temperature change of a few degrees. The principle of operation of this device is based on its expansion and contraction.
If the temperature in the heater is below the permissible value, then the thermostat on the heating radiator is retracted, thereby allowing a larger volume of coolant to be supplied, and when it rises, the device protrudes, and the amount of fluid passing through is reduced.
Disadvantages of mechanical regulators
It is natural that you can regulate the temperature of 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 a high probability of regular breakdowns of locking devices that are not able to withstand frequent closing and opening.
In addition, it is completely impossible to accurately control the temperature to which the heater is heated, and with it the air in the room, with a conventional tap.
The benefits of thermostats
Installation of thermostats on radiatorsheating will make it easy to get rid of all the above inconveniences and effortlessly create a comfortable microclimate in your apartment or house, and in each room - according to its own program.
A mechanical or electronic thermostat is indispensable for heating appliances in the kitchen, in rooms with window openings facing the sunny side, since when organizing a heating system in these rooms, it is necessary to take into account temperature fluctuations both in the daytime (additional heating of the sun), as well as at night. The installed electric thermostat on the heating radiator very subtly feels such changes, and this is a direct way to save energy resources, and, accordingly, financial resources.
Single-pipe heating system
Single-pipe heating system implies a serial connection of heating devices, and turning off even one of them leads to a violation of 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 using 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 be left with cold heaters.
Naturally, such a heating system requiresthermostat for 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 coolant will go through the bypass, while the radiators will remain cold.
Two-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, so for effective temperature control, you should use a different type of thermostats with a higher hydraulic resistance.
Installation recommendations
Thermostat for heating 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 thermostat in the zone of ascending air flows from radiators.
- The remote sensor must be firmly fixed with brackets on the wall.
- Heat flows in the room must have free access to the regulator, in other words, it must not be covered with furniture, screens, curtains, etc.
Installation of thermostats
After we figured out the installation site, you should consider how thermostats should be installed on heating radiators.
- This appliance mustbe set taking into account the direction of fluid flow. On each thermostat you can find an arrow, its direction must match the direction of the coolant flow. Accordingly, it must only be mounted 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 a vertical position, like a conventional valve or a faucet with the handwheel pointing upwards, the warm air flow from the valve body and from the return pipe will prevent the device from accurately responding to temperature changes in the surrounding air.
It is also worth paying attention to the fact that the thermostat for a cast-iron heating radiator should not be used due to inefficiency. The fact is that the operation of cast iron heaters is inertial, after blocking the flow of water, they radiate heat for a long time.
Settings
The thermostat should only be calibrated after the installation is completed and the heating system has been filled. It is important that the radiators are evenly heated. After that, you can start setting the thermostat. It is necessary to strictly adhere to the operating instructions and choose for the radiator the temperature mode that is required for a particular room.
How to set up a thermostat on a heating radiator:
- First of all, it is necessary to minimize heat loss, forthis closes all windows and doors.
- Regulator head turns all the way to the left, thus fully 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 turns all the way to the right, the valve closes.
- Gradually the air will begin to cool. After that, the head smoothly turns to the left.
- As soon as a 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 the graduated scale located on the case. This completes the thermostat setting.
