Thermostats for radiators of heating batteries, installation

Comfortable conditions in an apartment or a private house are a key element of a high quality of life for a particular person or family. They provide health, good mood, good rest for people before the next working day. The main constituent element of convenience and coziness is the microclimate and, above all, a favorable temperature regime.

Factors influencing the choice of microclimate

The optimal temperature range is considered to be 18-20 ⁰WITH. But in practice, homeowners are selective in their thermal performance based on several factors. Among them:

1. The composition of the tenants. If there are newborns or young children, especially if there is a threat of small drafts when opening the front doors, as a rule, the room temperature warms up to 22, and sometimes more degrees. Increased heat norms are provided in families with elderly people suffering from chronic diseases. With renal failure, a cool climate is not desirable in the patient's room (below +25

   ⁰WITH).
2. House structure. Erection of walls and roofs or their additional reinforcement with materials with increased thermal insulation properties. The spatial orientation of living quarters relative to the cardinal points and the wind rose.
3. Climatic conditions of the region, daily temperature fluctuations. In the foothills, the difference between the thermometer readings during the day and at night reaches 15 ⁰WITH.

Most of the factors are taken into account during the design phase of a heating system. Possible negative conditions are taken as a basis. with the addition of an operational margin strength. Incorrect accounting of the lowest possible temperatures will lead to freezing of pipes and the entire heating structure.

However, critical temperature values ​​have a time limit.

Room temperature stabilization

Violations of the heat balance in buildings not only reduce the comfort of staying in them for residents, but are also fraught with negative health consequences. The problem is aggravated by the fact that different rooms usually require an independent microclimate.

To correct the thermal regime, temperature regulators for heating batteries are used.

Types of devices for heat management of radiators

To change the air temperature in the room, special products called regulators are installed on the heating batteries. They are of two types: manual and automatic..

Manual is a standard valve-type sanitary faucet. The principle of operation is based on changing the volume of the coolant entering the radiator. The smaller it is, the lower the heat transfer of the heater. Installed at the entrance to the battery. Regulation of the intensity of the flow of the energy carrier is carried out by locking or unlocking to the desired position of the shut-off device. The mechanism is reliable and relatively durable. Not very difficult to install and operate. As a rule, anti-corrosion valves are used. These are brass, bronze, copper alloys.

The main disadvantage is that the adjustment of the thermal regime to the desired value is often carried out several times a day. Much depends on changes in ambient temperature. It takes time to measure the heating of the radiator to the required values. Their accuracy is poor.

Automatic is called a thermostat for radiators. Work, as well as a hand-made product, is based on controlling the amount of thermal energy entering the radiator. The regulation is carried out by a special valve, which expands or contracts in accordance with the set parameters. When the temperature in the battery drops below the norm, the valve is recessed, opening the way for more hot water to flow through the circuit. With an overestimated heat output, it reduces the passage of the energy carrier.

Classification of thermostats

Devices are almost everywhere replacing valve taps. They are distinguished by high quality of performance, accuracy of achieving the required indicators, ease of adjustment, and reliability. They are divided into 3 main types:

1. Mechanical thermostats for radiators. The amount of hot water is supplied manually. The devices are simple in design and easy to operate. They have a high degree of reliability and precision in regulating heat transfer from radiators. Affordable. Typical products are approximately the same in structure. Components: heating radiator thermostat, valve, regulator, actuator, Sylphon (metal jacket). The gas or liquid located in the shell acts on the stem, which locks or unlocks the passage of the coolant to the radiator at the required level. The position of the substance in the Sylphon is controlled by a rotary mechanism on the outside of the product.
2. Electronic temperature controllers on a heating radiator are innovative high-tech devices, although they are identical in structure and principle of operation to mechanical products. The main feature is the microprocessor. It is programmed to the required parameters. Sulfon is usually filled with liquid. The scheme of work: with excessive heating, the liquid expands and presses on the corrugated walls of the shell, driving the stem, which closes the valve. With a decrease in the heat of the radiator, the opposite process occurs. Sylphon is manufactured from highly durable engineering plastics. The service life is over 10 years. Withstands up to several hundred thousand compressions and expansions. Therefore, in some cases it is used to regulate the heating of boilers. Information to the microprocessor about the air temperature in the room comes from a remote temperature sensor.
3. Semi-electronic thermostats for heating. In terms of basic properties, they are close to mechanical devices. Controlled by thermostatic heads via Sylphon. The heads are oriented towards the interior of the room. Relatively large in size. Therefore, the sensor is remote. Attached to the head with a capillary tube.

Features of self-installation of devices

Installation of devices does not cause any difficulties. The preferred option for mounting products on the radiator inlet pipe. Some models do not function when attached to the battery outlet. The height from the floor should be 80 cm. This is due to the fact that the temperature difference in the lower and upper parts of the room can reach several degrees. The middle position more accurately reflects the ambient temperature. When using an external temperature sensor, the height is determined by it. The device should not be exposed to direct sunlight; it should be avoided by covering it with curtains, decorative elements or other foreign objects.

Taking into account the fact that thermostats often use Sylphon with liquid, in order to avoid errors, it is preferable to place them horizontally. Otherwise, there will be difficulties with the flow of matter into the Sylphon.
