How is hot water heating calculated? Hot water supply (DHW). What is thermal energy for hot water supply

In accordance with the Decree of the Government of the Russian Federation dated May 13, 2013 No. 406 “On state regulation of tariffs in the field of water supply and sanitation,” with a centralized hot water supply system in a closed system, a two-component tariff for hot water is established, consisting of “ cold water component "(rub./m3) and " component for thermal energy "(RUB/Gcal). The resource supplying organization supplying hot water makes settlements with the contractor utilities (Management Company, HOA) for 2 resources: · cold water– according to the tariff for the “cold water component”; · thermal energy– according to the tariff for the “thermal energy component”. The value of the component for cold water is calculated by the tariff regulatory body based on the tariff for cold water. The value of the component for thermal energy is determined by the tariff regulatory body in accordance with methodological instructions based on the following components: · tariff for thermal energy; · costs of maintaining centralized hot water supply systems in the area from the central heating points (inclusive), where cooking is carried out hot water, to the point on the border of the operational responsibility of the subscriber and the regulated organization in the event that such costs are not taken into account in the tariff for thermal energy; · the cost of thermal energy losses in pipelines in the area from the facilities where hot water is prepared, including from central heating points, including the maintenance of central heating points, to the point on the border of the operational responsibility of the subscriber and the regulated organization in the event that such losses do not taken into account when setting tariffs for thermal energy; · costs associated with the transportation of hot water. Providers of utility services in accordance with the “Rules for the provision of utility services to owners and users of premises in apartment buildings and residential buildings", approved by Decree of the Government of the Russian Federation dated May 6, 2011 No. 354 (hereinafter referred to as the Rules), calculate the amount of payment for utility services for hot water supply for the volume of hot water consumed in cubic meters. In accordance with the Rules, the amount of payment (P i) for utility service for hot water supply, in a room equipped with an individual hot water meter, is determined by the formula: P i = V i n * T k p (1), where: V i n is the volume (quantity) consumed during the billing period in the i-th residential or non-residential premises communal resource, determined from the readings of an individual meter; T to p — tariff for a utility resource. Since the tariff for the utility resource “hot water” is set in the form of two components, the utility service provider with consumers of hot water makes payments for the components: cold water and thermal energy for hot water supply needs. Amount of thermal energy (Gcal/ m 3) for hot water supply needs per 1 m 3, as a rule, is determined by the utility service provider on the basis of general house (collective) readings of hot water meters and thermal energy in hot water. It should be noted that the utility service provider makes settlements with the resource supplying organization based on the readings of the same common house (collective) metering devices for hot water and thermal energy in hot water. The consumed amount of thermal energy in hot water in the i-room (Gcal) is determined by multiplying the amount hot water according to an individual metering device (m 3) by the specific consumption of thermal energy in hot water (Gcal/m 3). The volume of hot water determined according to an individual metering device (m 3) is multiplied by the tariff “component for cold water” (rub ./m 3) is the payment for cold water as part of hot water. The volume of thermal energy in the consumed hot water (Gcal) is multiplied by the tariff “thermal energy component” (rub./Gcal) - this is the payment for thermal energy as part of hot water water.According to information letter FTS of Russia dated November 18, 2014 No. SZ-12713/5 “On the issue of regulating tariffs for hot water in a closed hot water supply system for 2015”, it is stated that the executive authorities of the constituent entities of the Russian Federation in the field of state regulation of prices (tariffs) has the right to make a decision on the establishment of tariffs for hot water in a closed hot water supply system per 1 cubic meter. m. In this case, the calculation of the tariff for hot water (T hot water) per 1 m 3 is made according to the formula: T hot water = T hot water * (1 + K pv) + US central heating + T t/e * Q t/e (2), where :T hvs - tariff for cold (rub./cubic m);T t/e - tariff for thermal energy (rub./Gcal); K pv - coefficient taking into account water losses in closed systems heat supply from central heating points to the connection point; US central heating - unit costs for the maintenance of hot water supply systems from central heating points to the boundaries of the balance sheet of consumers (without taking into account losses) in the event that such costs are not taken into account in tariffs for thermal energy (power), per 1 cubic meter. m;Q t/e - the amount of heat required to cook one cubic meter hot water (Gcal/cubic m). At the same time, the amount of heat for preparing one cubic meter of hot water (Q t/e) is determined by calculation, taking into account heat capacity, pressure, temperature, water density, thermal energy losses in risers and heated towel rails Thus, the charge in the receipt for hot water depends on the form in which the regulatory body sets the tariff for hot water: for two components (cold water and thermal energy) or per cubic meter. In question the amounts of charges for 2 components (cold water and thermal energy) are given, but not indicated municipality and tariffs for components. If we assume that hot water consumption was 10 m3, then the tariff for the “cold water component” is 331 rubles. / 10 m 3 = 33.10 rubles/m 3. If we assume that the tariff for the “thermal energy” component is 1800 rubles/Gcal, the amount of thermal energy consumed is: 1100 rubles. /1800 rub./Gcal = 0.611 Gcal, respectively, to heat 1 m 3 of hot water, the thermal energy consumption was 0.611 Gcal / 10 m 3 = 0.0611 Gcal/m 3.

The main advantage of a direct-flow water supply system compared to a circulating water supply system is its simplicity. There are no water coolers, circulating water pumping stations, additional pipe networks or other structures. If there is no need to purify industrial waste water, then the entire cold water supply system will consist of a pumping station and a system of supply and discharge pipelines. The advantage of a recycling water supply system is that a significantly smaller amount of water is supplied from the source than with a direct-flow system; this amount of water should only compensate for its losses from evaporation and carryover of droplets by the wind from the coolers and the water consumption for blowing cold water, which depends on the quality of the added water and the method of processing it. As a rule, the amount of water added to the system does not exceed 5% of the circulating water flow. With recycling water supply, the diameter of water pipelines, and therefore their cost, are significantly reduced, the size and cost of water intake structures are reduced and pumping stations the first rise, the energy consumption required to supply water to the territory of the enterprise, it becomes possible to use sources with a small water flow for industrial water supply, the cost is noticeably reduced treatment facilities for additional water. With a recirculating system, much less waste water is discharged into the reservoir than with a direct-flow system. In this regard, the task of protecting water bodies from pollution is simplified. wastewater, the size and cost of treatment facilities and pipelines that discharge waste and treated water are reduced.

Hvs on the receipt what is it

It is unacceptable to change the names of these services, although some regional housing and communal services arbitrarily enter lines such as “ DHW heating", "DHW make-up" or " DHW drainage and HVS". It is not at all necessary for the consumer to know how much it costs to heat water; what is important to him is the final amount that is presented for payment.

Is it legal to pay for water heating using a receipt in 2020?

If the legality of the additional line “water heating” in receipts is in question, in order not to overpay for heating, it is recommended to first contact the Criminal Code with a request to explain what this means this item. The appearance of a new line in the receipt is legal only on the basis of the owner’s decision MKD premises. In the absence of such a decision, you should write a complaint to the State Housing Inspectorate. After filing a complaint with the Criminal Code, you must be provided with an answer with explanations within thirty days. If you refuse to justify why such a service is indicated in the receipt, you should file a complaint with the prosecutor's office with a claim in court. In this case, if you have already paid the amount indicated in the receipt, the basis for the claim will be Article 395 of the Civil Code of the Russian Federation. If a refund is not required, but you must pay for services that are not provided to you, file a claim to exclude the “water heating” line. In this case, it is worth referring to Article 16 of the Law “On Protection of Consumer Rights”.

What is DHW in the receipt?

It turns out to be a vicious circle - many residents often do not pay for hot water due to its low temperature or refuse this service altogether, switching to water heating electric boilers. And heating network enterprises cannot carry out repair work, because... the population's debt to pay does not give them an influx Money.

Is it legal to pay for hot water supply (hot water supply) in the receipt is divided into 2 payment points: 1 - water supply (I have 331 rubles); 2 - heating it (1100 rubles)

· the cost of thermal energy losses in pipelines in the area from the facilities where hot water is prepared, including from central heating points, including the maintenance of central heating points, to the point on the border of the operational responsibility of the subscriber and the regulated organization in the event that such losses do not taken into account when setting tariffs for thermal energy;

What is hot water supply, hot water supply and sewerage in housing and communal services receipts

List of services that residents must pay for apartment buildings, is clearly defined by Article 154 of the main industry document - the Housing Code. Homeowners and tenants are required to pay for housing maintenance and repairs. In addition, their responsibility includes payment for services:

What is cold water for hot water in the receipt

The cold water component is the volume of cold water (CW) for hot water supply needs. If there are individual metering devices (meters), this component is determined - according to the readings of the hot water metering device (DHW), in the absence of an individual metering device - according to the standard, i.e. 3.5 cubic meters per 1 person. per month.

What does the abbreviation HVS DPU mean?

The nuance is that if accounting is kept by an enterprise, then it will blame all kinds of losses in water and its temperature (for example, breakthroughs, leaks) on consumers, and they will pay for it. If a house has a communal meter installed, then residents will pay for the water and heat supplied to the house.

Few of the residents of houses No. 1, 2, 3 of microdistrict 4A delve into the amounts charged by the management company. The amounts for hot water from an individual boiler room are generally a “dark forest”.

Let's count costs for hot water supply (DHW) for October 2015, house No. 1. There are many incomprehensible definitions in hot water bills (DHW IPU, DHW cold water IPU, individual consumption and ODN, as well as the mysterious “DHW circulation”), which will be very interesting to understand.

So, house No. 1 has an individual boiler room, which means hot water cost will be equal to the cost of cold water + the cost of heating it to 60-75 degrees.:

LLC “Management Company “Comfort”, which services building No. 1, sets the following lines for payment for hot water:

"HVS DHW IPU"- this is the cost of cold water that entered the boiler room. We multiply the volume of cold water in the hot water supply system by the tariff of 19.66 rubles.

"Warming up the IPU"- This theoretical cost of heating cold water. These are precisely the theoretical costs of heating water from ~8 degrees to ~65 degrees. This parameter will always be less than “practical” heating, since the water is heated once, passes through the pipeline system in the house and is “reheated” again, and these cycles are repeated. This “additional heating” of water is distributed separately in the bill under the item “DHW circulation”.

"DHW circulation"- this is an additional parameter characterizing the cost of heat loss in pipes, heated towel rails, etc. To better understand this parameter, imagine that only one person has moved into the house, and the entire boiler room of the house works for him, heats and circulates water through the pipes, heats it up and sends it back through the circuit. The bill for a single resident to heat 1 cubic meter of water will be huge compared to theoretical heating. Therefore, this “circulation” is distributed evenly among all owners and there is common sense: pay for the fact that the boiler room heats up and delivers constantly hot water to the meter, even for those owners who do not live or use their premises.

How is payment for consumed hot water distributed among residents? Here's the formula:

DHW = Volume * ("CW DHW IPU" + "Heating IPU") + "DHW circulation" (1)

In October 2015, house No. 1 consumed 762 cubic meters of hot water, who went to the boiler room. Of them 688.15 cubic meters- this is the sum of the residents’ hot water meter readings submitted to the management company. Remaining 73.85 cubic meters- this is the volume that the remaining residents, for various reasons, did not report to the Criminal Code. Therefore, the costs of these cubic meters are distributed evenly to all consumers of hot water in the house.

Let us describe formula (1) in more detail, taking into account individual and “general household” consumption and circulation losses:

1. The total cost of expenses for the period was RUB 172,751.08.
2. The coolant consumption in the heating system according to the metering device was 391.168 Gcal.
3. Coolant consumption for hot water supply according to the heat meter - 167.886 Gcal.
4. The total volume of coolant for the period is 559.054 Gcal.
5. Tariff for heating and hot water supply - 309.01 rubles. for 1 Gcal

Let us separate from the total expenses the share of costs for heating cold water:">

Cost of cold water (let's multiply the 762 cubic meters consumed by the house by the tariff of 19.66 rubles per 1 cubic meter):">

Now let's see whether the management company distributed the payment for hot water according to the receipt correctly. Here is the receipt available: for October 2015 (house No. 1). The living area of ​​the apartment is 33.7 sq.m. The living area of ​​apartments and commercial premises in the building is 13,552.40 sq.m.

Just follow the formula:

The result was an amount approximately comparable to total costs at 66,858.71 rubles, i.e. The management company calculated for October 2015 hot water with an error of less than 2%, we will assume that is correct.
