Thermal heads on radiators. main advantages. installation

Autonomous heating networks are arranged in almost every private house. During their construction, modern devices began to be used to ensure comfort and significant savings in energy resources. One of such devices is a thermal head for a radiator.

With its help you can maintain a constant temperature in the room without human intervention.

Main advantages

Many owners of individual houses are thinking about whether to put such a device. In this regard, it is recommended to get acquainted with the main advantages of the products, then the decision will become obvious.

The following are the positive aspects of the products:

• When operating the device, it is possible to maintain a certain air temperature in a particular room, regardless of the level of heat loss.
• Using this device makes it possible to significantly save on fuel.
• The price of products is not very high, so even consumers with low incomes can buy it.
• The installation technology does not imply any particular difficulties, therefore installation is allowed to be done by hand.

Reference! Programmable models allow you to automatically change the readings of the thermometer during the day, while the accuracy reaches one hour. Temperature measurements are made every minute.

general information

Thermal losses of premises can vary greatly, since different materials can be used in construction. Therefore, during heating, the temperature difference may vary significantly depending on the particular room. To compensate for this factor allows the installation of thermal heads on the radiator.

Types of products

The presented devices allow control of the supply of the working medium directly to the battery. All of them can be categorized as mechanical or electronic devices.

In the first case, manual adjustment of parameters is carried out, and in the second - automatic.

• Mechanical devices are small heads with a rotary knob that has several modes. When switching by one division, as a rule, it is possible to increase or decrease the temperature by 2-5 degrees in the range from 7 to 28 degrees.
• Electronic counterparts provide an opportunity to fully automate the process of functioning. Models of this type make customization more flexible. Some of them allow you to set the temperature with an accuracy of one degree.

Note! Electronic devices can be divided into products with open and closed logic. The first ones have certain limitations in terms of functionality, and the second ones do not.

Components

To understand how the thermal head works on a heating radiator, it is necessary to become familiar with the basic elements of the design. Despite the relatively small size, this device contains a lot of components.

All of them are listed below.

• The thermostatic element is a corrugated shell made of materials that can withstand many cycles of compression and tension.
• The working medium is a solid, liquid or gaseous substance that is sensitive to temperature changes.
• Thermostatic valve allows you to skip the right amount of coolant in a specific device of the heating system.
• The scale setting allows you to make settings for the operation of this device.
• Rod refers to the kinematic elements capable of transmitting translational motion from the drive.
• The spool acts as a special component, directing the flow of the working medium through the displacement of moving parts.
• The spring-like compensation mechanism closes the main valve while reducing the volume of the working substance.
• A detachable connection is necessary to connect the device with the feed pipe.
• The union nut is used to fasten the components of this device.
• The locking ring provides the ability to set a certain temperature.

Attention! Familiarization with the basic elements of the device will help to understand the principle of operation of the thermal head for a heating radiator, even if there is no basic knowledge in the field of technology.

Device operation

The operation of the device is based on reducing or increasing the coolant inlet to the battery. The operation of the bellows initially implies a certain pressure. Inside it is a chemical that reacts to changes in temperature.

The spring located in the inner part of the element has some parameter of compression force, which allows settling the temperature with the pressure value. The impact increases when the device warms up. The volume of the bellows increases significantly, which leads to a narrowing of the passage way.

The hole closes until a certain temperature is reached. When cooling the process proceeds in the opposite direction, that is, the bellows decreases in volume. In connection with this, the walkway becomes much wider.

From the above information it becomes clear how the thermal heads work for radiators of the heating system. Since the installation process does not provide for complex actions, it can be done without professional help.

It is allowed to introduce both a straight and an angle tap with a thermal head for a radiator into the heating system of a dwelling. The first one is mainly mounted in one-pipe networks, and the second one in two-pipe networks.

Common mistakes

When installing a device to adjust the temperature, the choice of location plays an important role, otherwise it will not be possible to achieve the most efficient operation.

The most frequent mistakes lie precisely in the wrong location of devices.

• Devices are located directly in the niches.
• Devices are installed in places where they are covered with curtains.
• Thermal heads are installed in a vertical position.
• The fixtures are located under the wide sill.

Addition! Before you install the thermal head on the radiator, you must carefully inspect the place. If there are heating surfaces nearby, then the device cannot be installed.

Work

On the supply pipe of the heating system, a special kit is installed for the bottom connection of a radiator with a thermal head or an angular counterpart.

To ensure reliable operation during installation, follow the steps below.

1. First, the pipelines completely overlap, after which the coolant is drained.. Work is recommended before the onset of the heating season.
2. Carefully prepared seat. The supply pipe is cut in a certain place. If a valve is installed on it, then dismantle it.
3. The body of the product is mounted on the assembly from the side of the riser, for which a locknut is screwed. After wrapping with sealing material, the thermostat itself is worn directly.
4. At the final stage, the control element is installed. The counterpart of the structure is screwed into a special adapter located on the device case.

Note! When fixing a radiator valve with a thermal head, you should not over-tighten the nut, otherwise you can simply disrupt the thread. The use of force in this case should be moderate.

Implementation settings

To ensure a sustainable microclimate in a residential area, doors and windows must be tightly closed. Heat fluxes or small drafts can degrade tuning accuracy.

When working in the central part of the room is a special stand with a thermometer. After that, the device valve is opened. When the temperature rises within 5-7 degrees, the valve is completely shut off.

After reaching a comfortable temperature, the valve turns to the left until the sound of water in the thermostat is heard.

As a conclusion

The above instructions should help beginners who want to understand how to properly install the thermal head on the radiator of the heating system of any configuration. Additional information on this topic is reflected in the video in this article.
