What is a thermostatic head with a remote sensor? Thermostatic heads for radiators

If the apartment or house in the winter is hot, you have to open the windows. So the temperature in the room is normalized. But the cost of heating the premises is quite high. To reduce them, the coolant must be used expediently. To adjust the heating temperature to the radiators, install a device such as a thermostatic head. It effectively uses a coolant and saves a lot of money from the family budget.

Principle of operation

Some homeowners during the heating season adjust the heating temperature of the radiators by partially shutting off the tap. This is a wrong approach, because with such operation of the fittings they quickly fail. Their purpose is to be found only in a fully open or closed position. To be able to reduce the cost of heating, thermostatic heads for radiators are used.

Their principle of work is completely different. Using the scale on the device, the desired room temperature is set. When the radiator pushes it to the specified level, the thermostat blocks the flow of the coolant. This is not partial, but completely. As soon as the temperature decreases, the feed resumes. This is very convenient and cost-effective from an economic point of view.

Head device

Thermostatic head has a certain principle of the device. Some models are characterized by additions and manufacturer-specific features. But the principle of all is similar.

The device consists of a valve and the head of the thermostat itself. Inside the latter is a sealed corrugated chamber. It is called a bellows. This chamber is filled with a special substance that, when heated, expands in a certain way.

The system starts to press on the valve stem, and it blocks the flow of the coolant. As the material inside the bellows, liquid, gas or solid can be used. By the type of such filler, thermostatic heads for radiators of different manufacturers are distinguished. The speed of response of the device to changes in ambient temperature depends on this.

Principle of economy

When purchasing the device presented to the consumer, the cost of heating costs is promised to 35%. In different cases, this figure will be significantly different. Since the principle of operation of the heads is to completely cut off the supply of the coolant, they are used only in autonomous heating systems.

Never use the appliance if it is cool in the home. But when the room is hot, the thermostatic head will be relevant. The main economic effect of its application is observed in the off-season or when the temperature difference day and night is quite large.

If the heating system is designed correctly, as well as all of its elements are properly installed, the device will be quite effective. In certain periods of the heating season, the economy will be really palpable.

Types of installation

There are two basic principles of the device presented. The first option involves measuring the temperature directly on the radiator at the location of the head. This is a rather inaccurate approach, but it has the right to exist.

The second option involves using a device such as a thermostatic head with a remote sensor. Measurement of temperature occurs in the absence of the effect of ascending heated streams from the battery. The sensor in this case correctly determines the temperature in the room.

Thanks to this feature, the second type of installation is preferable. If the sensor is positioned correctly, the measurements will be correct. This is especially felt in the winter, when the temperature of the coolant is high. Batteries and pipes emit significant heat radiation. It can lead to errors in determining the heating of a conventional head.

How does the device work?

There are many manufacturers offering products to the consumer. But the thermostatic head of Danfoss, Giacomini, Purino, etc. is quite different in principle. Therefore, their functions should ideally be considered.

Let's say the user has set the desired room temperature +23 degrees. At different manufacturers, this mark on the head can be indicated by a number, a point, etc. As soon as the heating reaches a predetermined level, the substance in the bellows expands, presses on the valve stem. When the room temperature is +24 degrees, the coolant supply to the radiator stops. The room becomes cooler. When the temperature drops by 1 degree, the battery operation resumes. In the room, it is determined +22 degrees. But in reality, everything can be a little different.

Installation

In order for the device to work correctly, the installation of the thermostatic head must be carried out strictly according to the manufacturer's instructions. The valve is installed on the water supply pipe to the radiator. The head should not be located vertically, but horizontally. This will allow it to better capture the temperature of the air in the room.

Do not install the radiator deep in a niche under the windowsill. If the battery covers the decorative panel or thick drapes, the use of a remote sensor is extremely necessary. This element should be placed so that it does not obscure anything.

The installation site must be carefully considered, otherwise a mistake in measuring the temperature will lead to a supercooling of the room. An improperly installed sensor significantly reduces the responsiveness of the device to the heating of air in the room. Strictly following the recommendations of the manufacturer, you can conduct the installation yourself.

Select a device

Thermostatic head, the price of which depends on many parameters, can be with different bellows filler. The cheapest varieties have a solid inside. The rate of its response to temperature changes is rather low. Therefore, it is better not to save on quality and purchase more efficient products. Manufacturers such as Giacomini, Purmo (500-700 rubles) use as a filler bellows liquid. Such devices quickly adapt to the surrounding conditions.

One of the leaders in sales today is the thermostatic head of Danfoss worth 1000-1500 rubles. Its work is caused by the action of a gaseous substance. With the correct installation of the device, its operation is most approximated to the ideal variant. Gas faster than other bellows fillers reacts to changes in heating in the room. Therefore, the heating system is set up much faster.

Having familiarized with such a device as a thermostatic head, it can be concluded that it is necessary for a properly designed autonomous heating system. The quality of this device is better not to save, otherwise the effect of its use will be minimal.
