With the beginning of the heating season, utility bills increase significantly. And it is not always justified. The fact is that usually apartment owners pay for heat consumption according to average indicators. Therefore, it is useful to install heat meters in the house, which save up to 40% on payment. Installation of meters is carried out on the pipes of the inlet and outlet of the coolant. In apartment buildings with riser wiring, heat meters are usually installed in the basement.

Instructions

Step 1

Today the State Register of SI recommends installing about 200 types of heat meters. Its choice depends on many indicators. Of course, the type of heat meter depends on the type of coolant and the heat input scheme. For the right choice, you need to know the maximum flow rate of the coolant, information about which is owned by heat supply organizations. To determine the number of primary converters and the model of the heat meter, it is necessary to have information about the number of heat inputs and the type of DHW system. The parameter of the pressure drop in the direct and return pipelines of the heating network is also significant.

Step 2

Secondly, when choosing a heat meter, take into account its computing capabilities and characteristics. So, the error in measuring heat according to the established standards should be no more than ± 4% with a temperature difference in the pipelines of more than 20 ° С, and the error in measuring the mass of the coolant should not be more than ± 2%.

Step 3

Third, consider the range of changes in flow, temperatures and temperature differences. It must be said that all certified heat meters today comply with regulatory requirements in terms of ranges. They record the change in the flow rate of the coolant, its temperature and its difference.

Step 4

The fourth rather serious criterion for choosing a heat meter is the pressure loss on it. Almost all meters have hydraulic resistance, which, when installed, creates pressure losses in the pipelines.

Step 5

An important factor when choosing a heat meter is its installation method. So, many of them require significant sections of a direct pipeline (up to 10 m), which is not always feasible in basements and living quarters.

Step 6

When choosing a heat meter, pay attention to its registration mode, ease of maintenance, an intuitive interface, the presence and depth of the archive, the check interval. An important factor is the price of the heat meter.
