In modern heating systems, involving the layout of underfloor heating, special heating temperature regulators for radiators are installed. The main function of these devices is to change the degree of heating of the room by changing the volume of coolant that passes through radiators. Properly used and installed controllers can increase the efficiency of the heating system.
Structural elements
Externally, the regulator resembles the most ordinary tap installed at the inlet or outlet of pipelines from radiators, however, instead of the classic valve, these devices are equipped with a quick-detachable nut, with which a thermocouple is attached to the body.
Heating temperature controllers for radiators and similar control devices for radiators, as a rule, consist of two main systems:
- Thermostatic valve (valve).
- The mechanism that contributes to the impact on the valve stem (thermostatic head or thermocouple).
A thermostatic valve is required to effectively control the heat transfer from the heating device. At the same time, the amount that passes through the radiator should constantly change depending on the room temperature.
Regulator Features
Temperature controllers for radiators operate in automatic mode. In the beginning, it is only necessary to determine the necessary degree of heating of the heater by means of a graduated scale located on the thermal head.
Modern regulators operate in such a way that they never shut off the coolant supply to the radiators, but only reduce or increase it depending on the room temperature.
The valve is a device that exercises fine control over the heating of the heater. When determining the temperature regime in the room, the error will be minimal. How to adjust the temperature of the heating battery correctly will be discussed below.
Principle of operation
One of the key parts of the thermostatic control valve is considered to be a stem, which is equipped with a rubber gasket. This rod is movable, it can rise and fall, while changing the diameter of the hole through which the coolant enters the radiator.
When the valves open in the radiators, a large volume of liquid will begin to circulate, and they will heat more. The temperature regulator of the heating batteries with the stem lowered will reduce the amount of coolant passing through. For a heater, this means less intense heating.
Main types
Temperature regulators for radiators can be of the following types:
- Devices with mechanical adjustment of fluid flow through the valve.
- Devices with a thermostatic head that is controlled by a bellows.
- Devices with a thermostatic head, which is controlled by a remote thermostatic sensor.
All three types of this equipment can be combined on one basis - the presence of a thermostatic valve. It is located at the bottom of the structure. The main difference lies in the thermal head.
A special scale is located on the valve head. Thanks to these numbers, you can set the desired temperature.
Main types
Today, temperature controllers are used for radiators of the following types:
- The heating system, which needs regulation, is equipped with two pipes.
- Thermostats are installed in a heating system with one pipe.
The regulator, which is installed in a two-pipe system, is usually calculated in such a way that, when the pressure drops, it does not go out of operation. This is due to the fact that balancing is done through losses near the valve. To overcome this problem, the temperature regulator of the radiator of the heating batteries is equipped with a small bore and a large hydraulic resistance.
Installation Features
It is worth noting that heating appliances controlled by temperature regulators are able to create completely new conditions for the heating system. For example, after long-term cold weather, the temperature finally became several degrees higher. Accordingly, the heat loss in the room has become less.
The regulators of heating temperature for radiators perceive this information unambiguously as a signal to blocking the coolant. In this case, its consumption drops, and then gradually tends to zero. Accordingly, the pressure in the heat conduit begins to gradually increase. To prevent discomfort, in such situations, designers install a bypass valve in the system immediately after the circulation pump.
Temperature in heating batteries: norms
The heating system should work in such a way that the rooms are comfortable. As a rule, the temperature regime is regulated by normative and technical documentation. For example, in kindergartens and hospitals it is 21 degrees Celsius, in residential buildings - 18 degrees Celsius. However, depending on the outdoor temperature, the room loses a different amount of heat with air currents during ventilation and through building envelopes. Heating of the coolant in the heating system, depending on external factors, can vary over a fairly wide range. The temperature in the heating batteries (standards prohibit temperatures above 90 degrees Celsius due to the decomposition of coatings and dust) can be from 30 to 90 degrees Celsius.
Schedules designed specifically for each building must be used. They express the dependence of the outdoor temperature on the parameters of the coolant. It also applies automatic control according to the sensor.
In order for the temperature of the heating batteries to be optimal and the regulation to be correct, you should use high-quality equipment and have information on how to do this correctly.
Regulation instruction
The heating setting procedure is performed during the installation of thermostats and radiators. However, not everyone knows how to regulate the temperature of the heating battery.
So, self-regulation of heating devices is as follows:
- A crane is attached to each device, which allows you to accurately and smoothly adjust it at the same time. In this case, the use of ball valves is not permitted.
- First of all, it is necessary to open all the available locking devices and select the coldest room. In the selected room, you will need to continue all further actions.
- After that, the tap opens completely.
- To simplify the temperature control procedure for each individual room, you should purchase a separate thermometer (heat sensor) and install it.
- Using a thermostat, the boiler is heated to the required temperature. You also need to pay attention to the aspect that cold rooms need to be warmed up slightly more than others.
- As soon as the temperature is normalized in the coldest rooms, it will be possible to move to other rooms and perform similar actions through the controller. To do this, screw the taps on the radiators in such a way that the air can heat further. As soon as the required thermal regime is created, it is necessary to set the temperature on the boiler.
Conclusion
So now you know how to adjust the temperature of the heating battery correctly. However, for the regulation to really be of high quality, it is necessary to purchase good thermostats from well-known manufacturers. Then the heating system will serve for many years.
To install a thermostat, it is preferable to seek the help of qualified specialists who have long and professionally been engaged in this business in order to prevent further serious troubles. Consultation about the equipment you have chosen you can get in any specialized store.
