Heat supply
You can do without a common house heat meter, but it will soon become an expensive pleasure. If your house does not have a meter, then you pay according to the standards. On top of that, you already have multipliers applied to you. Every year they will grow. It is legal. It is spelled out in Decree of the Government of the Russian Federation of April 16, 2013 344. The document says about the following multiplying factors for residential premises without metering devices:
since 2017 1.6.
Let's add, in comparison with the standards, even without a multiplying factor, the payment in apartment buildings with metering devices is still lower. True, savings will not work if the windows are broken in the entrance, the attics are blown through, and there is ice in the basement. According to the norms, the entrance should be at least 12 degrees Celsius. And if there is no access heating, the walls of the apartments begin to “cry”, the temperature drops by 4-5 degrees. It makes no sense to install heat meters in such houses.
Recall that initially, according to Federal Law 261, all multi-apartment residential buildings with central heating were to be equipped with common house metering devices until July 1, 2012. Then the dates were repeatedly postponed, until 2015. Today, fines in violation of the law threaten management companies, HOAs and housing cooperatives, that is, legal entities. And the residents of such houses will simply pay more for heat.
When the installation of metering devices is not possible
The increasing factor is applied only if it is technically possible to install the meter. There are residential buildings that are exempt from the installation of common house heat meters. Their list is determined by the Ministry of Regional Development of Russia in Order 627 of 12/29/2011.
Installation of metering devices is not possible if this requires:
Reconstruction;
Capital repairs;
Creation of new house systems.
Common house meters are not installed if it is not possible to ensure compliance with technical requirements, as well as create conditions for their proper operation.
The reason for this may be:
Emergency state of house systems;
Non-compliance with the temperature regime;
Non-observance of permissible humidity;
Failure to comply with permissible electromagnetic interference;
Inability to provide access for reading and maintenance.
In this case, the managing organization or the HOA should take care of drawing up a special act and provide it to the heat supply organization.
Necessary actions for the installation of general house heat meters
1. General meeting of residents. First of all, residents must general meeting and make a decision on it to install a meter and finance its installation, because the heat metering unit belongs to the common property apartment building. 2. Application for technical specifications. The next step is an application to the organization supplying heat to your home. There you will be given the technical conditions that are needed when drafting the project. Without technical conditions, the heat meter readings will not be taken into account in the calculations. The technical conditions indicate the parameters of the heat supply system: configuration, thermal load, maximum flow rates of the coolant, design pressure, temperature graph.
3. Choosing a contractor. Owners need to choose an organization that will prepare the project, install the meter, and will be engaged in warranty and service maintenance. The organization must be licensed.
4. Equipment selection and project development. You can choose a metering device yourself or entrust it to a company with which the residents decide to work. It is necessary to take into account the features of heat meters, efficiency, service life, cost.
5. Project approval. This should be done by the company with which the contract for work on the metering device has been concluded. The company coordinates the project with the heat supply organization.
6. Installation and commissioning. Installation work on the installation of a common house appliance is usually carried out within one day at temperatures not lower than minus ten degrees. After the meter is installed, it is necessary to invite an inspector from the heat supply organization. The inspector inspects and seals the metering unit, draws up an act of admission of the metering unit. The act is signed by the inspector of the heat supply organization and the representative of the owners. Starting next month, payment for heat supply should be charged according to the readings of the meter. And for the previous months - according to the standard, taking into account the increased coefficient.
How to pay for the meter
Heat meters cost a lot. Citizens can choose one of two options: pay immediately (in this case, the tenant will have to pay about 1.5 - 3 thousand rubles), or repay these costs in installments over several years. In this case, several tens or hundreds of rubles will be added to the usual utility bill every month, depending on the cost of the meter and the chosen payment period.
In accordance with the Federal Law "On Heat Supply" the Government Russian Federation decides:
1. Approve the attached Rules for the commercial accounting of thermal energy, heat carrier.
2. Federal authorities executive power within 3 months to bring its regulatory legal acts in line with this resolution.
3. The Ministry of Construction and Housing and Communal Services of the Russian Federation shall approve within 2 weeks the methodology for commercial metering of thermal energy, coolant.

111. The amount of thermal energy, coolant received by the consumer is determined by the energy supply organization based on the readings of the consumer's metering station devices for the billing period.
112. If in order to determine the amount of supplied (consumed) thermal energy, heat carrier for the purpose of their commercial accounting, it is required to measure the temperature of cold water at the source of thermal energy, it is allowed to enter the specified temperature into the calculator in the form of a constant with periodic recalculation of the amount of consumed thermal energy, taking into account the actual cold water temperature. The introduction of zero cold water temperature is allowed throughout the year.
113. The value of the actual temperature is determined:
a) for the heat carrier - by a single heat supply organization based on data on the actual average monthly values of the temperature of cold water at the heat source provided by the owners of heat sources, which are the same for all consumers of heat energy within the boundaries of the heat supply system. The frequency of recalculation is determined in the contract;

115. If there are no metering devices at the metering points or the operation of metering devices for more than 15 days of the billing period, the determination of the amount of thermal energy spent on heating and ventilation is carried out by calculation and is based on the recalculation of the base indicator for the change in outdoor temperature for the entire billing period.
116. The value of the heat load specified in the heat supply contract is taken as the base indicator.
117. Recalculation of the base indicator is carried out according to the actual average daily outdoor temperature for the billing period, taken according to meteorological observations of the weather station closest to the object of heat consumption territorial body executive power, which performs the functions of providing public services in the field of hydrometeorology.
If during the period of cutting the temperature graph in the heating network at positive outdoor temperatures there is no automatic control of the heat supply to heating, and also if the temperature graph is cut during the period of low outdoor temperatures, the value of the outdoor air temperature is assumed to be equal to the temperature indicated at the beginning of the cut graphic arts. With automatic control of heat supply, the actual temperature value indicated at the beginning of the graph cutoff is taken.
118. In the event of a malfunction of metering devices, the expiration of their calibration period, including the withdrawal from operation for repair or verification for up to 15 days, the average daily amount of thermal energy, heat carrier determined by metering devices for the time regular operation in the reporting period, reduced to the calculated outdoor temperature.
119. In case of violation of the deadlines for submitting instrument readings, the amount of thermal energy, heat carrier determined by metering instruments for the previous billing period, reduced to the estimated outdoor air temperature, is taken as an average daily indicator.
If the previous settlement period falls on another heating period or there are no data for the previous period, the amount of thermal energy, heat carrier is recalculated in accordance with paragraph 121 of these Rules.
120. The amount of thermal energy, coolant spent on hot water supply, in the presence of separate metering and temporary malfunction of devices (up to 30 days), is calculated based on the actual consumption determined by metering devices for the previous period.

126. In the cases specified in paragraph 125 of these Rules, the amount of leakage is determined as the difference between the absolute values of the measured values without taking into account errors.
In other cases, the amount of heat carrier leakage specified in the heat supply contract is taken into account.
127. The mass of the heat carrier consumed by all consumers of thermal energy and lost in the form of a leak in the entire heat supply system from the source of heat energy is determined as the mass of the heat carrier consumed by the source of heat energy to feed all pipelines of water heating networks, minus internal costs for own needs during production electrical energy and in the production of thermal energy, for the production and economic needs of the objects of this source and intra-station technological losses by pipelines, units and apparatuses within the boundaries of the source.

b) in relation to the heat carrier transferred at the border of the balance belonging of adjacent heat networks, the calculation is based on the balance of the amount of heat carrier released into the heat network and consumed by heat-consuming installations of consumers, taking into account the losses of the heat carrier associated with emergency leaks of the heat carrier, executed acts, standards for technological losses at transfer of thermal energy, approved in the prescribed manner, and losses exceeding the approved values (excess).
129. The distribution of excess losses of thermal energy, heat carrier between adjacent heat networks is carried out in quantities proportional to the values of the approved standards of technological losses and losses of thermal energy, taking into account emergency leaks of the heat carrier through damaged thermal insulation.
130. In case of transfer of thermal energy, heat carrier through a section of the heat network owned by the consumer, when distributing losses of thermal energy, heat carrier and excess losses of heat energy, heat carrier, the specified heating network are considered as adjacent heat networks.
