Heating battery thermostators - how to choose and install

To ensure the optimal temperature regime in the room and optimize utility costs, it is necessary to regulate the rate of receipt of the coolant into the radiator. With this task, thermostat batteries are perfectly copier.

Consider the features of the work and installation of various types of thermostats, we define the main criteria for choosing a high-quality, reliable thermostat of batteries.

The need to use the battery thermostat

With the arrangement of the heating system, many are wondering: "Does the thermostat on the battery need?". Today, when bills for the heat consumed by the population are steadily rising, the answer is unequivocal: "Yes."

Very often, the tenants of multi-storey houses are forced to open the windows in winter to reduce the heat from the preheated batteries. The energy of the coolant is consumed irrational. This is especially noticeable for those who have heat meters.

The thermostat (thermostat) of heating batteries is a device that controls the microclimate indoor. Some models have the ability to program the temperature regime at different times of the day (day / night) and every single day.

Using a totality of thermostat with heat meter - an effective way to reduce room heating costs

Additional advantages of thermostators for batteries can be attributed:

Purchase and installation of the thermostat of batteries in private houses and cottages pays off for one heating season

Installation of a thermostat for radiators in heating apartments is particularly relevant for premises with significant temperature fluctuations: kitchen, living room and "sunny" rooms.

Types of thermostats: device and work principle

Consider the classification of thermostats for batteries for two main criteria:

1. According to the principle of adjustment:
   • mechanical;
   • automatic.
2. By type of working substance Thermal heads:
   • gas-filled;
   • liquid.

Mechanical thermostat

The mechanical thermostat for the battery consists of two main parts:

• thermostatic valve;
• high sensitivity element (thermal head).

The mechanism works simply and reliably without energy raising from the outside. The thermal head includes: a regulator, drive, and a gas or liquid working element.

The principle of operation of the mechanical thermostat is as follows:

1. The temperature of the coolant in the heating system changes under temperature exposure.
2. The bellows perceives the changes that have occurred and moves the regulating spool. The movement of the spool is associated with any temperature change in the room.

The sensitive element (liquid, gas) responds to the movement of the rod - such a change in the stroke allows you to adjust and control the flow of the coolant into the radiator.

Various factors can affect the operation of the thermostagulator:

• draft or ventilating room;
• outdoor temperature;
• sunlight;
• availability near the thermostat of other heat or cold sources (refrigerator, heater, hot water pipe).

Electronic thermostats

Electronic thermostats are programmable microprocessor devices for adjusting and maintaining the temperature regime of housing. The thermostat carries out automatic control of the elements of the heating system (pump, boiler, mixer). The consumer is enough to set the desired temperature, and the built-in sensor will be adjusted over the entire heating season.

The main element of the electronic thermostat is a thermal sensor transmitting information about the temperature indicators of the zone in which it is installed. The thermarigilator responds to information and optimizes the mode to a given temperature.

Digital thermostats with closed and open logic were widespread.

Electronic thermostators with closed logic Have a permanent, clearly specified work algorithm that does not depend on the environment. You can manage only the main parameters. For household use such a thermostat is quite enough.

Electronic thermostators with open logic Have free programming and are able to adapt to any system in which it will be involved. More often such devices are used in industrial spheres, as programming and change of settings takes a lot of time and must be performed by highly qualified specialists.

In everyday life is not rarely used and ordinary electronic thermostatssimilar to mechanical analogs, but with an electronic display. They function in simple mode. To their work, it is enough to set the temperature that will constantly be maintained, or set the permissible range of temperature fluctuations.

Electronic thermostators operate from batteries and are supplied with a recharge device.

Liquid and gas-filled thermostators

As a working substance, the thermal heads usually performs gas or liquid (paraffin). I must say that cheaper and common - liquid thermostats. However, gas-filled thermostators are more accurate and faster to react to changes in pressure inside the bellows.

The advantages of the design of the gas-filled thermostat:

• gas condensation occurs in the cooled part of the device distant from the valve body, so the operation of the thermostat does not depend on the water temperature (coolant);
• the thermostat is very susceptible to the temperature fluctuations of the room, which makes it possible to effectively control the heat gain.

Installing thermostators on heating batteries

Thermostat installation schemes for single and two-pipe heating system

When installing the thermostat on the battery in a single-tube system, you will have to change the radiator connection scheme and install an additional jumper - bypass.

Bypass will connect the direct and reverse laying of the coolant. This will allow the coolant during the battery overlap. In addition, the possibility of dismantling the radiator is to close the valves (3 and 4 in the figure).

In a two-pipe heating system, the thermostat is installed on the upper supply tube, and the valve is mounted on the bottom.

Decoding designations:

• feeding;
• battery;
• mechanical or electronic thermostat;
• lower valve;
• airlock;
• bypass (jumper);
• reverse riser;
• stub.

Rules of competent installation

The thermostat will work smoothly and efficiently if its installation is made competently, in compliance with all the rules:

Thermostat installation sequence on the battery

Consider the phased installation of the thermostat on the heating battery:

Bypass diameter should be one size less than the diameter of the supply pipes. For example, for the pipeline ¾ inch diameter of the closing section should be ½ inches

Setting the thermostat

The mechanical thermostat after installation must be configured - set the optimum temperature in the room. For this, the following actions are performed:

In electronic thermostat, it is sufficient to set the desired temperature on the display. If functionality allows - you can choose the temperature regime for day and night time, for different days of the week, for example, intense room heating on weekends, and economical on weekdays. This mode is optimal for country houses and cottages, where the owners appear only on the weekend.

In order to buy a thermostat for a heating battery and do not regret your acquisition over time, it is necessary to accommodate the thermostat to choose the choice of thermostat and take into account some important points:

Especially efficiently, from an economic point of view, the use of battery thermostators in private houses and cottages with autonomous heating, in apartments with centralized heat carrier, the use of thermostats allows to improve the microclimate of the room by setting a more comfortable temperature.
