Technical conditions for the installation of a heat meter validity period. Is it profitable to install an individual heat meter in an apartment and how to do it right

Heat energy meter or heat meter- this is a device, according to the indications, which is charged for the received thermal energy.

Purpose of installation

By installing a meter, it becomes possible to control the cost of thermal energy, make decisions on the implementation of energy saving measures. After installing a heat meter, payments for heat, as a rule, are reduced, but the meter itself does not provide savings.

The reduction in costs is due to payment for the actually delivered heat, and not according to calculations based on the average monthly ambient temperature and the standard temperature in the apartment.

Thermal energy meters can be installed both in a separate apartment and in an apartment building.

A meter installed for one consumer is called individual, for several consumers - collective. As you know, from the course of general physics, the amount of heat is calculated by the formula Q \u003d m × (t1-t2).

To calculate the thermal energy, the values ​​\u200b\u200blook like this:

• Q - The amount of heat;
• m is the mass of water passing through the heat meter in one hour (water consumption);
• t1 is the temperature in the supply pipeline;
• t2 is the temperature in the return pipeline;

They also work on these 3 indicators. To measure the temperature, thermal sensors are used, which are installed in the return and supply pipelines. The difference in heat meters in the types of measurement of the amount of water.

Varieties: pros and cons

There are several types of heat meters:

1. Tachometric. These are mechanical devices. The principle of their work is quite simple. The flow meter must be connected to the heat supply system of the house, and it will take into account the amount of coolant that has passed through it. An impeller is installed inside the flow meter, which rotates from the flow of water. As you know, the batteries in the apartment and the house are heated by hot water. For heating systems with very hard water, it is better not to use mechanical devices, The cost is relatively low.
2. Ultrasonic. This type of counters has a large number of modifications. However, they all work on the same principle. It is installed on the supply or return pipe. As an example, the following type of installation: the emitter is installed after the battery, and the sensors are installed in front of the radiator. These meters are distinguished by a rather high accuracy class, while the price of such devices is quite acceptable and depends on the modification.
3. Electromagnetic. This type can be classified as the most expensive. This is the price of great opportunity. It can be used to account for thermal energy both in closed heating systems and in open ones. It additionally allows you to take into account the water flow and temperature flow. All processes are automated, and calculation data is displayed on the screen.
4. Vortex. They are able to measure not only water, but also steam. According to the principle of operation, they differ from other heating meters. The device is installed on a pipe between 2 nozzles.
5. Radiator diffusers. Most often they are installed on heating radiators in apartments where there are several heating risers.

Device installation procedure: instructions

You need to do the following:

1. Hold a meeting of all residents of the house and document the decision to install a heat meter, select a responsible person (draw up and sign a protocol).
2. Send a letter to the heat supply organization in order to obtain technical specifications for the installation. It is important to consider that the place of installation of the heat meter will be the boundary of responsibility for the condition of the pipelines. Before the TCO metering station - after the apartment owners or the management company. The specifications will state:
   • installation location;
   • its technical characteristics;
   • diameters of pipelines on which the installation will be carried out;
3. With received specifications it is necessary to contact the design organization for the preparation of project documentation. The project for the installation of a heat meter, as a rule, is typical, but requires adaptation to a specific installation site. Documentation can take up to two months to complete. The project must include:
   • A specific model of the heat meter (preliminarily agreed with the customer), corresponding to the received technical conditions.
   • Installation diagram.
   • Estimated documentation.
4. The developed project must be approved by the organization which issued the specifications. The approval period is from 1 to 2 weeks, provided that the documentation was not sent for revision.
5. It is necessary to purchase a meter specified in the project documentation. When buying, please note that the passport of the heat meter is with a valid stamp of the state verifier.
6. Installation of a heat meter. The installation of heating meters is carried out only by specialists, and such work cannot be carried out on their own. It is necessary to contact a company that has all the necessary permits for the provision of services of this kind.
7. For commissioning it is necessary to sign an agreement with the enterprise supplier of thermal energy. Although this step seems simple, it can take a long time. Before putting it into operation, it is necessarily sealed. The responsibility for the integrity of the seals during the entire period of operation lies with the owner.

During operation, it must be passed for state verification once every 4 years. This is done to verify correct operation. Also, in the non-heating season, it is necessary to clean the mechanical filter and replace the batteries.

The owner is obliged to properly operate the meter, in accordance with the technical requirements. Thus, the owner of the metering unit must sign a contract for the maintenance of metering devices with a service organization (for example, it can be an installation company, an energy supply organization, a management company).

Readings for calculations for the released heat are taken once a month on the dates specified in the contract. When taking readings, representatives of the heat supplier and the consumer are present. The recorded data are entered into the relevant act and confirmed by the signatures of both parties.

Calculation of heat energy consumption

The calculation for the received heat is made according to the amount of heat consumed for a certain period, at the price specified in the contract. For example, 50 Gcal were released per month at a price of 1,100 rubles per 1 Gcal, therefore, 55,000 rubles were payable.

Now you need to decompose the amount for all homeowners. To do this, it must be remembered that thermal energy is used not only for heating apartments, but also for non-residential premises.

Therefore, the area of ​​heated non-residential premises is evenly distributed in proportion to the living area for all owners.

For example, if the total area of ​​the house is 1200 m2 and the living area is 1000 m2, then for each meter of living space there is 0.2 m2 of non-residential area. Then add up the area of ​​​​the apartment and the area of ​​\u200b\u200bher share in the house property. The result is multiplied by the cost of heating one "square meter".

At whose expense and how much does it cost to install the device?

According to the Federal Law (as amended on July 18, 2011) dated November 23, 2009 No. 261-FZ, until July 1, 2012, owners of premises in apartment buildings are required to ensure the installation of heat energy meters.

Paragraph 12 of Article 13 of Federal Law No. 261-FZ establishes that in the event of non-fulfillment by the owners of premises in an apartment building, the obligation to ensure that such a house is equipped with a common house meter, used communal resource, the organization that supplies the house becomes the person obliged to ensure that the house is equipped with the indicated device appropriate community resource.

Price installation is quite expensive. But given the fact that the cost of the entire complex of works is decomposed into all homeowners, the numbers do not look terrifying.

So, to install a meter for a typical five-story building, you will have to pay about 400 thousand rubles.. After recalculating the cost of installation, according to square meters of living space, it turns out about 4 thousand rubles from the owner of an apartment of 50 m2. If such an amount is unbearable, then homeowners are entitled to installment plans for up to 5 years. True, you will have to pay interest on the loan at the level of the refinancing rate.

The payback period for installing heat meters is on average 3-4 years. If you additionally engage in phased energy saving, you can achieve savings of 30 - 40%.

Any buildings and apartments that are connected to the district heating network use heat to organize and maintain the optimum temperature for consumers. A device that organizes the control of the amount of energy is called a heat meter. Such a device must meet the requirements for heat metering units in accordance with the concluded agreement with representatives of the heating network. It can also control readings and parameters during the operation of heat carriers (water and steam circulating in heating devices) at consumers.

Rules for the organization of commercial metering of thermal energy

When using a heat meter under a contract, the consumer pays only for the amount of heat produced. This device is needed to save the amount of heat consumed and reduce fuel costs in accordance with the signed contract after the adoption of the act. Technical metering of thermal energy is the organization of control of power grid equipment necessary in a modern building.

The requirements for commercial heat metering units say that these are devices for organizing temperature and volume measurement of heat energy. According to the rules, they consist of a flow meter, inlet and outlet temperature sensors and an electronic calculator. Given the information on the mass of the flow, the consumer can determine the volume of water and steam that the equipment produces from the meter.

To organize the measurement of parameters, consumers can use the following formula: the mass of heat produced is equal to the volume of heat supplied through the flow meter, multiplied by the difference in temperature in the supply and return pipelines. This indicator is multiplied by the heat transfer coefficient, which characterizes the parameters of the equipment according to the operating contract.

The current technical conditions and the passport of the heat energy metering station determine the installation rules. For example, a heat meter must be included in the register of measuring instruments, like any other metrological device.

According to the technical specifications for organizing the installation of heat metering devices, flow meters are mounted on straight sections of the system, and temperature sensors are mounted on pipelines with a diameter of at least 70 mm with the inclusion of additional fittings (filters, ball valves, measuring pressure gauges and thermometers). Works are carried out by representatives of the heating network.

This set of heating system equipment is called a commercial metering unit according to the rules of the organization. Requirements for work on its installation are regulated in article 19 (Organization of commercial accounting of thermal energy, heat carrier of the Federal Law "On Heat Supply").

Installation of measuring equipment

According to the rules for installing heat meters, there are two ways to install measuring devices:

1. Measurement of temperature and energy mass requires the organization of heat meters on each heat carrier. To get the total mass heat consumption for an apartment, the consumer needs to add data on all equipment in the reporting period.
2. The organization of one metering device for heat consumption at the riser and temperature sensors is carried out on each heat carrier at consumers. At the same time, the scope of work on reprogramming is determined by representatives of the heating network. They also add data for each pipeline to get the total consumption by consumers.

Only single-pipe horizontal systems allow measurement with one heat meter. However, such devices are equipped only in industrial and industrial buildings. Therefore, an effective solution to the problem, which does not require significant capital investments and reconstruction of the premises, is the installation of commercial temperature measuring instruments.

Requirements for heat energy meters

According to the specifications, commercial measuring devices are mounted on pipes in specially designated areas. It is necessary to provide access to heat meters and equipment for accounting and control.

The requirements for the installation of metering devices are based on the need to recognize them as commercial equipment that monitors the heating system for several years. These include:

• mandatory registration in the register of measuring devices;
• organization of protection against unauthorized intervention in the operation of equipment in the reporting period;
• the minimum number of recorded parameters for calculating energy volume measurements;
• autonomous power sources that will last at least 5-6 years;
• compliance with the standard calibration time period (depending on the type of meter).

The choice of the metering unit is carried out according to the characteristics of the coolant. Limits of permissible relative errors for meters, registration of operating time and downtime are regulated by the project. These parameters are determined by the requirements of the organization of commercial metering units.

Engineering equipment is selected as follows:

• consumers are determined by the type of equipment included in the register, or those devices that have passed the state metrological certification;
• for the measuring device, it is necessary to provide comfortable rooms to which unauthorized access is impossible. You also need reliable waterproofing and affordable lighting, in which it is easy to read meters.

When developing a project for a metering station, it is necessary to determine the technical data and take into account the requirements and recommendations for the organization and assembly of measuring instruments, pipe fittings, pollution protection equipment and connecting elements. Installation must be carried out under the contract, then the act is accepted by the head of the heating network. Detailed information can be found in the manufacturer's data sheets and regulatory documents for the equipment. Also, the operating agreement defines the forms of reporting statements of meter readings.

The beginning of the organization of the work of the measuring control device is carried out by the representative of the heat supply together with the consumer after the acceptance of the device. Two identical copies of the certificate of admission to operation of the heat energy metering unit are drawn up, while one copy is provided to the consumer, the other to the heating network employee. The act of commissioning a heat metering unit for consumers is approved by the head of the heating network within a few days.

Heating is one of the most expensive items on your utility bill. The calculation is based on standards and tariffs - indicators established in accordance with the legislation of the Russian Federation by the executive authorities of the subject in the field of state regulation of prices. Also, the payment structure may include the volume of heat energy consumption in the event that a common house heat meter is installed in an apartment building. Let's find out in which cases installation is required, how to do it correctly and how residents will benefit.

Appointment of a common house meter for heating

After the Housing Code determined what is the property of tenants, their area of ​​responsibility has expanded significantly. Responsibilities for the maintenance and service of common house property fell on the shoulders of apartment owners.

Since it is impossible to refuse to pay for general house needs, it makes sense to reduce the cost of heating residential and non-residential premises and pay only for the heat actually received.

To measure the amount of energy consumed, a common house heat meter (ODPU) is installed. By paying for heating in an apartment building by the meter, you will be able to control energy consumption and keep track of expenses. This is not the only purpose of the ODPU installation.

Another goal pursued is to encourage residents to save heat outside their own apartments and take good care of common property.

If the doors and windows in the entrance are tightly closed, the heat will remain, and the residents will receive the service in full.

It should be mentioned right away that the ODPU itself does not save anything. This is just a metering device that provides more accurate data for determining the final amount of payment for heating than the standards.

Installing a common house heat meter is legal

For the first time, general house meters were discussed back in 2009, when Federal Law No. 261-FZ “On Energy Saving and Increasing Energy Efficiency” was issued. In its original version, the law prescribed the mandatory installation of an ODPU in multi-storey buildings until January 1, 2012. Later this period was extended several times.

The last change in the deadline until January 1, 2019 and until January 1, 2021 (for Crimea and Sevastopol) was enshrined in Federal Law N196-FZ of 07/26/2017.

Thus, the law on common building meters for heating unequivocally confirms the need for their installation in apartment buildings. An exception is allowed only for dilapidated, emergency and demolished houses, as well as objects on which the installation of a meter is technically impossible due to the inconsistency of the engineering network parameters with the installation conditions of the device.

Procedure for installing a collective heat meter

If the centralized heat supply system has the technical ability to install a common house heat energy meter, it must be installed.

In newly built houses, energy meters are installed before the facility is put into operation. This requirement contains the law on the installation of a common house meter dated November 23, 2009 No. 261-FZ in paragraphs 7-8 of Article 11, and paragraph 9 of Article 13 defines the area of ​​responsibility for installing an ODPU in houses where it is not available.

In order for a house-wide metering device to appear in the house, it is necessary to go through several stages of the installation procedure.

1. The meeting of owners of an apartment building (MKD) is the basis for the installation of heat meters for heating in an apartment building.
2. The meeting may be initiated by the Management Company. In, ZhSK, ZhK, the meeting is held on the basis of an application from the owners, 10% of the signatures of the total number of votes are sufficient.
3. The technical conditions for the ODPU installation, in accordance with which its design and installation will be carried out, are issued by the heat supply organization.
4. The project for the installation and the estimate for the work is prepared by the design organization, taking into account the specific installation site and indicating the model of the device.
5. Coordination of the project in the heat supply organization that issued the technical conditions.
6. Acquisition of the ODPU approved by the project, necessarily with a verification mark.
7. Installation of ODPU and putting the meter into operation.

Organizations responsible for the installation

According to Law No. 261-FZ, the obligation to install a collective heat energy meter lies with the apartment owners of a multi-storey building, who must carry out this measure on their own, choosing an equipment supplier and a contractor for the work.

Assuming that there will be houses that are not equipped with ODPU, legislators have determined who should install heat meters in this case. So, if on July 1, 2012 there was no heat meter in the houses, the responsibility for its installation was shifted to the resource supply organization (RSO).

In addition, the RNO is obliged to prepare proposals for equipping apartment buildings with metering devices and carry out the relevant work, which is confirmed in the letter of the Federal Antimonopoly Service of Russia dated 08.12.2011 No. AG / 45584.

Thus, the widespread information that the management company installs meters for heating is erroneous. The task of the CC is only to:

• bring to the attention of the owners of MKD apartments the need to install a collective heat meter;
• organize a meeting;
• draw up a protocol of consent.

Measures for installing the device can be carried out by organizations supplying heat energy or specialized companies that have:

1. Qualified specialists in the staff of the company.
2. Permission to perform the relevant type of work issued by the SRO.

How much does a common house heating meter cost

Since heat meters for heating, in accordance with Law No. 261-FZ, are the property of residents of an apartment building and they bear all the costs of their purchase and installation, the issue of the cost of the ODPU is very important. Consider what items of expenditure make up the amount of installation of a collective meter.

1. The cost of the device. The price of a heat meter directly depends on its type and manufacturer. There are several types of heat meters:

• tachometric - the cheapest models (6-10 thousand rubles) with a service life of 2 to 4 years;
• vortex - a more expensive option, the average price of which is 15 thousand rubles;
• electromagnetic - costing 15-17 thousand rubles;
• ultrasonic - depending on the model, the price from the manufacturer ranges from 15,000 to 50,000 rubles.

1. The cost of preparing a document containing the technical specifications of the heat supply system and developing design documentation for the metering station equipment.
2. The price of an additional set of equipment and related materials.
3. Installation cost: installation, electrical installation, as well as commissioning.

All costs result in a rather high amount: from 150 to 300 thousand rubles. Here it is to be paid to the residents of the house. You can do this in several ways:

• one-time payment (mandatory for legal entities);
• installment payment, which is provided for a period of up to 60 months and is paid in equal installments. The interest rate depends on the refinancing rate set by the Central Bank.
• means of the overhaul fund, provided that this service is included in the list of works on common property in the MKD for the constituent entity of the Russian Federation, in accordance with the Housing Code of the Russian Federation (part 2 of article 166).

The payment mechanism is regulated by law: the amount is distributed among all apartment owners, depending on the area of ​​​​housing and the timing of depositing funds.

Take a sociological survey!

Maintenance of common house heat energy meters

Maintenance of the meter involves maintaining it in working condition. This is achieved as a result of preventive measures, such as:

• inspection and elimination of the causes affecting the wear and tear of the control and measuring unit;
• checking the operation of additional equipment;
• operational maintenance and control of the metrological accuracy of measurements of the metering device;
• weekly readings for analysis and development of recommendations for maintaining the required temperature.

If during the test a malfunction is detected, the device is dismantled, the damage is repaired and reinstalled.

Reconciliation of readings of a common house heat meter

To calculate monthly payments, accurate and timely readings are needed, which are taken from the common house meter. In accordance with Decree of the Government of the Russian Federation No. 354 dated 05/06/2011, the utility service provider is responsible for accounting for heat energy, which may be:

• Management Company;
• resource organization.

Results

The Law on Energy Saving obliges residents of apartment buildings to install common heat meters at their own expense, with the exception of houses that do not meet technical capabilities.

Both the UK and the RSO take part in the installation procedure of the ODPU, the former organizes, and the latter is responsible for the installation of the device. In case of failure to fulfill their obligations, companies will be fined, and residents will receive a receipt for payment for heating with a multiplier. Time will tell how expedient the compulsory installation of collective meters is, but the effect of the use of ODPU is undeniable: heating costs are reduced by up to 30%.

IV. The procedure for determining the amount of supplied thermal energy, heat carrier for the purpose of their commercial accounting, including by calculation

110. The amount of thermal energy, coolant supplied by a source of thermal energy, for the purpose of their commercial accounting, is determined as the sum of the quantities of thermal energy, coolant for each pipeline (supply, return and make-up).

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 source of heat energy provided by the owners of heat energy 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;

B) for hot water - by the organization operating the central heating point, based on measurements of the actual temperature of cold water in front of hot water heaters. The frequency of recalculation is determined in the contract.

114. Determination of the amount of delivered (received) thermal energy, heat carrier for the purpose of commercial accounting of thermal energy, heat carrier (including by calculation) is carried out in accordance with the methodology for commercial accounting of thermal energy, heat carrier approved by the Ministry of Construction and Housing and Communal Services of the Russian Federation (hereinafter referred to as the methodology). In accordance with the methodology, the following is carried out:

A) organization of commercial accounting at the source of thermal energy, coolant and in thermal networks;

B) determination of the amount of thermal energy, coolant for the purpose of their commercial accounting, including:

The amount of thermal energy, coolant released by the source of thermal energy, coolant;
the amount of thermal energy and mass (volume) of the coolant received by the consumer;
the amount of thermal energy, coolant consumed by the consumer during the absence of commercial metering of thermal energy, coolant according to metering devices;

C) determination of the amount of thermal energy, coolant by calculation for connection through a central heating point, individual heating point, from sources of thermal energy, coolant, as well as for other connection methods;

D) determination by calculation of the amount of thermal energy, heat carrier in case of non-contractual consumption of thermal energy;

E) determination of the distribution of losses of thermal energy, coolant;

E) during the operation of metering devices for an incomplete billing period, the adjustment of heat energy consumption by calculation for the time of absence of readings in accordance with the methodology.

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. The 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 heat consumption facility of the territorial executive body that 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.

121. In the absence of separate accounting or inoperative state of devices for more than 30 days, the amount of thermal energy, heat carrier consumed for hot water supply is taken equal to the values ​​\u200b\u200bestablished in the heat supply contract (the amount of heat load for hot water supply).

122. When determining the amount of thermal energy, coolant, the amount of thermal energy supplied (received) in the event of emergency situations is taken into account. Emergency situations include:

A) operation of the heat meter at coolant flow rates below the minimum or above the maximum limit of the flow meter;
b) operation of the heat meter when the temperature difference of the heat carrier is below the minimum value set for the corresponding heat meter;
c) functional failure;
d) change in the direction of the heat carrier flow, if such a function is not specifically provided for in the heat meter;
e) lack of power supply to the heat meter;
f) lack of coolant.

123. The following periods of abnormal operation of metering devices should be determined in the heat meter:

A) the duration of any malfunction (accident) of measuring instruments (including a change in the direction of the coolant flow) or other devices of the metering unit that make it impossible to measure thermal energy;
b) power outage time;
c) the time of absence of water in the pipeline.

124. If the heat meter has a function for determining the time during which there is no water in the pipeline, the time of lack of water is allocated separately and the amount of heat energy for this period is not calculated. In other cases, the time of lack of water is included in the time of the emergency.

125. The amount of coolant (thermal energy) lost due to leakage is calculated in the following cases:

A) leakage, including leakage on the consumer's networks to the metering station, is identified and formalized by joint documents (bilateral acts);
b) the amount of leakage recorded by the water meter when feeding independent systems exceeds the normative one.

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 heat networks, minus intra-station costs for own needs during production electric 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.

V. The procedure for the distribution of losses of thermal energy, coolant between heating networks in the absence of metering devices at the boundaries of adjacent heating networks

128. The distribution of losses of thermal energy, coolant, as well as the amount of thermal energy, coolant transferred between the heat networks of heat supply organizations and heat network organizations in the absence of metering devices at the borders of adjacent parts of heat networks, is calculated as follows:

A) in relation to heat energy transferred (received) at the border of the balance sheet of adjacent heat networks, the calculation is based on the balance of the amount of heat released into the heat network and consumed by heat-consuming consumer installations (for all owner organizations and (or) other legal owners of adjacent heating networks) for all sections of pipelines at the boundary (boundaries) of the balance belonging of adjacent sections of the heating network, taking into account the losses of thermal energy associated with emergency leaks and technological losses (pressure testing, testing), losses through damaged thermal insulation in adjacent heating networks, which are formalized by acts , norms of technological losses during the transmission of thermal energy and losses exceeding the approved values ​​(excess losses);

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 transmission of heat energy, heat carrier through a section of the heat network owned by the consumer, when distributing losses of heat energy, heat carrier and excess losses of heat energy, heat carrier, these heat networks are considered as adjacent heat networks.
