Heat distributors in the apartment

Heat distributors allow to take into account the consumed thermal energy with the maximum economy in terms of payment. At the same time, there is a tendency to reduce heat consumption. In order to correctly and successfully implement such a scheme, it is necessary to consider three aspects that are interrelated. First, a regulatory and technical framework is being developed and approved. Secondly, reliable and cost-effective regulatory and accounting means are selected. It is also necessary to treat the consumption of heat rationally, take into account its payment depending on the actual use.

Substrate for installation

At the state level, a relevant law has been adopted, according to which individual heat meters must be installed in reconstructed and erected buildings for residential use.

Appropriate regulations allow the installation of heat spreaders . Apartment counters are used for horizontal distribution of heating systems, they are installed in the heating inlet. In the case of vertical wiring, these devices are not suitable for two reasons: they are too expensive to mount on each radiator element, nor do they capture the miserable costs and temperature changes to be measured on each heater.

How does the device work?

Heat distributors after 4-5 minutes measure the temperature of the radiator at a particular point, the results are stored in nonvolatile memory as a thermal difference in the area of the battery and air in the room. Consequently, the readings are identical to the amount of heat that came from the radiator during the accounting period. Data are accounted for in conventional units, which are then multiplied by the radiator coefficient corresponding to the specific type and size of the device.

With the same temperature readings in the room, as well as on the surface of radiators of different sizes, these distributors will be identical. However, the heat transfer of a large device is higher. To correct this moment, just this coefficient exists. Each manufacturer has an accounting table of this indicator for all types of radiators. The information is included in the computer programs for the allocation, which is automatically fixed when paying.

Heat accounting

Every year the indications in the apartments are taken out, and the total amount is distributed according to the actual indicators. On the tenants a balance is drawn between the amount of payments taking into account the indicative rates and the final payment. The final amount is credited for the use of heating in the next year. Therefore, in the presence of personal heat metering devices, the amount of payment for heating depends on the actual use in homes. The heat distributors are checked at intervals of 10 years.

The payback period of such installations for a two-room apartment is not more than one year with the service life of temperature regulators to thirty, and the distributors - up to ten years.

Organizational rules

There are several rules that will help you organize a housekeeping account using a heat spreader for a battery. These include:

• Mandatory installation on the heating units of thermostatic regulators.
• At least 75 percent of the rooms should be equipped with adjusting and distributing units.
• Spent heat energy for heating a house in fact must be accounted for by a meter common to the house.
• In the housing office, it is necessary to carry out a recalculation for citizens according to the indications of the registration devices.

Variants of radiator type

Any radiator heat distributor can be used for various wiring of the heating system, and it is much cheaper than the meter. The device is simple in installation, maintenance, the operational period is not less than ten years without additional verification.

Over 90 per cent of the existing housing stock and most of the residential buildings under construction belong to buildings with vertical wiring. In such constructions, besides distributors, there are no other effective technologies for apartment accounting.

It is worth noting that the considered device takes into account only a part of the heat received from the battery in the room. Some part is lost due to heat exchange through external wall partitions. These losses depend not only on the design and design solutions provided, but also on the outside air temperature.

Installation

For proper operation, the heat distributors in the apartment must be properly installed. The majority of manufacturers have developed and implemented the installation technologies for different types of heating units sold in the relevant market.

On some devices you can not install the distributor for technical reasons:

• Devices, inside of which there is steam.
• Models placed in the floor screed.
• Modifications that give heat from the ceiling of the room.
• Units with built-in electric fan.
• Devices with regulation by means of air valves.
• Devices where it is impossible to stop coolant plying.
• Products associated with outdoor air.

A specialist engaged in the professional installation of valves, in any given situation, can determine other limitations that prevent the installation.

Financial moments

On the two-pipe riser, it is possible to install regulators and heat distributors without problems. When wiring with one pipe, bypasses are required for the installation of the heat management unit. The meters in the room are installed regardless of their availability. The unit costs from a thousand rubles, the price of the system is from 5 to 6 thousand. It consists of a distributor, a radio transmitter, valves, bypass. The device provides information on the amount of heat given to the room (kWh). It is advisable from the economic point of view to install distributors together with regulators.

Based on the results of the full calendar year, the indications of each distributor, taking into account the radiator coefficient, will be similar to adjacent devices. After the information is removed tenants can roughly estimate the amount of payment. With the increase in tariffs, the costs will accordingly increase proportionately. Really, you can save only with proper operation of thermostats by reducing the temperature of the radiators.

Features

The units under consideration have a number of nuances concerning models and installations. For example, the distributor for a warm floor is included in the whole system of heat supply of a dwelling, differs by a special character of functioning. Taking into account that the coolant circulation is carried out along all pipelines of the unit, its preparation is carried out separately. For the insulation of the floor heating water installation from the "supply" and "return", a collector for the warm floor is provided , which is completed with a pumping group, a check valve and a distributor.

In addition, the units are divided into brands. There are many manufacturers, among which the brand "Pulsar" can be identified. It is designed by a German company, manufactured using European technologies and has the following advantages:

• Adapter made of aluminum, the price of which is included in the price of the product.
• It is possible to take data without entering the dwelling.
• There is a free program that reads the testimony.
• Simplified methods of adjustment and operation are applied.
• An open exchange protocol and protection from external heating are provided.

In addition, the "Pulsar" heat distributor has an indication of its removal from the radiator, the function of switching off for the summer period and the possibility of checking the readings by means of a checksum.
