In modern heating systems, involving the distribution of underfloor heating, special heating temperature controllers 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 the radiators. Correctly used and installed regulators can increase the efficiency of a heating system.
Constructive elements
Outwardly, the regulator resembles the most common tap installed at the inlet or outlet of pipelines from radiators, however, instead of a classic valve, these devices are equipped with a quick-release nut, with which a thermoelement is attached to the body.
Heating temperature controllers for radiators and similar controllersdevices for heating appliances, as a rule, consist of two main systems:
- Thermal expansion valve (valve).
- Mechanism that acts on the valve stem (thermostatic head or thermocouple).
A thermostatic valve is required to effectively control the transfer of heat from a heating appliance. At the same time, its amount that passes through the radiator must constantly change depending on the temperature of the room.
Regulator Features
Temperature controllers for heating batteries operate in automatic mode. At first, it is only necessary to determine the required degree of heating of the heater using a graduated scale located on the thermal head.
Modern regulators function 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 finely controls the heating of the heater. When determining the temperature regime in the room, the error will be minimal. How to regulate the temperature of the heating battery correctly will be discussed below.
Working principle
One of the key parts of the thermostatic valve is the stem, which is equipped with a rubber seal. This stem is movable, it can rise andlower, while changing the diameter of the hole through which the coolant enters the radiator.
When the valves are opened, a large volume of liquid will circulate in the heaters, and they will heat up more. A radiator temperature regulator with a lowered rod will reduce the amount of coolant passing through. For a heater, this means less intense heating.
Main species
Temperature controllers for radiators can be of the following types:
- Devices with mechanical adjustment of the flow rate through the valve.
- Units with a thermostatic head controlled by a bellows.
- Devices with a thermostatic head 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.
There is a special scale on the valve head. Thanks to these numbers, you can set the desired temperature.
Basic types
Today, heating temperature controllers are used for radiators of the following types:
- The heating system, which needs regulation, is equipped with two pipes.
- Temperature controllers are installed in the heating system withone pipe.
The regulator, which is installed in a two-pipe system, as a rule, is calculated in such a way that it does not go out of operation during pressure drops. This is due to the fact that balancing is carried out through losses near the valve. To overcome this problem, the radiator temperature controller is equipped with a small flow area and a large hydraulic resistance.
Installation features
It is worth noting that heaters controlled by thermostats can create completely new conditions for the heating system. For example, after long-term cold weather, the temperature finally became a few degrees higher. Accordingly, the heat loss in the room has become less.
This information is unequivocally perceived by heating temperature controllers for radiators as a signal to shut off the coolant. In this case, its consumption falls, and then gradually tends to zero. Accordingly, the pressure in the heat pipe 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 radiators: norms
The heating system must 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, inresidential buildings - 18 degrees Celsius. However, depending on the temperature outside, the room loses different amounts of heat with air flows during ventilation and through the building envelope. The heating of the coolant in the heating system, depending on external factors, can vary within a fairly wide range. The temperature in radiators (norms prohibit temperatures above 90 degrees Celsius due to decomposition of paintwork 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. Automatic regulation based on sensor readings is also applied.
In order for the temperature of the radiators to be optimal and the regulation to be correct, you should use high-quality equipment and have information on how to do it correctly.
Regulation instructions
The procedure for setting up heating is carried out 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 precise and at the same time smooth adjustment. Ball type valves are not allowed in this case.
- First of all, you need to open all available locking devices and select the coldestroom. In the selected room, you will need to continue all further actions.
- After that, the faucet fully opens.
- To simplify the procedure for temperature control for each individual room, you should purchase a separate thermometer (heat sensor) and install it.
- With the help of a thermostat, the boiler heats up to the required temperature. You also need to pay attention to the aspect that cold rooms need to be warmed up a little more than others.
- As soon as the temperature is normalized in the coldest rooms, you can go to other rooms and perform similar actions using the regulator. To do this, you should screw on the taps on the heaters so that the air can be heated 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 regulate the temperature of the radiator correctly. However, in order for the regulation to be of really high quality, it is necessary to purchase good thermostats from well-known manufacturers. Then the heating system will serve for many years.
To install the thermostat, it is preferable to seek help from qualified specialists who have been professionally engaged in this business for a long time in order to prevent serious troubles in the future. You can get advice about the equipment you have chosen in any specialized store.
