Temperature schedule for the supply of coolant to the heating system: SNIP 2021

Direct-flow water supply is a system consisting of a pumping station and pipe bends. Circulating water supply is a more economical option, since it uses fewer resources. The concept of heating cold water for domestic hot water means heating cold water to obtain hot water supply. An additional line appeared in receipts for paying for this service. You should understand in detail how legitimate the charges are.

What is DHW in the receipt

All services in receipts are regulated by article 154 in the Housing Code. Cold water supply means cold water supply and DHW means hot water supply.

Residential and industrial premises should be provided with an optimal temperature.

According to the accepted standards, the values ​​should be in the range of + 50-60 ° С.

Operators adjust readings based on environmental conditions. Central and autonomous systems are used for heating. Central water users pay for DHW heating. Residents of autonomous equipment pay for gas and electricity.

Cold water heating service includes several parameters. There are dead-end and looped boiler rooms that ensure the operation of the entire system. Uninterrupted operation is ensured with the help of equipment and optimal working conditions.

In the receipt, the DHW service includes:

  • Heating water using equipment in boiler rooms and supplying it to a ready consumer.
  • Preventive maintenance of heating equipment systems and mechanisms. Scheduled work and repair of routes in hot water supply networks.
  • Restoration of boiler rooms in round-the-clock operation. DHW is supplied on a permanent basis, but in summer the capacities are used sparingly.

Accordingly, the payment is received for heat and water.

Residents facing systematic temperature losses are forced to burn water on their own using a boiler and other automatic devices. The DHW service also remains in their receipts. To understand this situation, you need to refer to the legislation.

Temperature standards

Requirements for the coolant temperature are set out in the regulatory documents that establish the design, installation and use of engineering systems for residential and public buildings. They are described in the State Building Regulations and Rules:

  • DBN (V. 2. -39 Heating networks);
  • SNiP 2. 4. 5 "Heating, ventilation and air conditioning".

For the calculated supply water temperature, the figure is taken, which is equal to the temperature of the water leaving the boiler, according to its passport data.

For individual heating, it is necessary to decide what the coolant temperature should be, taking into account the following factors:

  • 1 The beginning and end of the heating season based on the average daily temperature outside +8 ° C for 3 days;
  • 2 The average temperature inside the heated premises of the housing and communal services public value should be 20 ° C, and for industrial buildings 16 ° C;
  • 3 The average design temperature should meet the requirements of DBN V. -10, DBN V. .-4, DSanPiN 5.. ... 08, SP No. 3231-85.

According to SNiP 2. 4. 5 "Heating, ventilation and air conditioning" (clause 3. 0) the limit values ​​of the heat carrier are as follows:

  • 1 For a hospital - 85 ° C (excluding psychiatric and drug wards, as well as administrative or household premises);
  • 2 For residential, public, and household facilities (not counting halls for sports, trade, spectators and passengers) - 90 ° C;
  • 3 For auditoriums, restaurants and premises for the production of categories A and B - 105 ° C;
  • 4 For catering establishments (excluding restaurants) - this is 115 ° C;
  • 5 For production premises (category C, D and E), where flammable dust and aerosols are emitted - 130 ° C;
  • 6 For staircases, lobbies, pedestrian crossings, technical premises, residential buildings, production premises without the presence of flammable dust and aerosols - 150 ° С.

Depending on external factors, the water temperature in the heating system can be from 30 to 90 ° C. When heated above 90 ° C, dust and paintwork begin to decompose. For these reasons, sanitary standards prohibit more heating.

To calculate optimal indicators, special charts and tables can be used, in which norms are determined depending on the season:

Calculation of water consumption in apartments where metering meters are not installed

The methodology for calculating water consumption in multi-apartment buildings (MKD) is associated with such additional issues as availability:

  • Crane in the apartment.
  • Bathroom.
  • Bathroom.
  • Other factors.

In the event that a person or family lives in a private house, then an additional item will be the use of water for irrigation purposes.

Consumption table according to SNIP 2. 4. 1-85

Basic payment formula

If, for objective reasons, you install and use a meter, the following principle of calculating the cost of water consumption by residents is applied: the water consumption standard per person is multiplied by the number of people registered (permanently and temporarily) on the living space and by the tariff in force in the region (cost one cubic meter of water). This rule is spelled out in paragraph 42 of the Decree of the Government of the Russian Federation No. 354.

In Moscow for 2021, a tariff for cold water consumption is set in the amount of 38.7 rubles per cubic meter, hot water - 191.72 rubles per cubic meter of water.

Norms of consumption in apartments without appliances

As mentioned above, the rate of water per person without a meter in each region is calculated according to the methodology approved in the field.

So in Moscow, the water norm per person per month living in an apartment building in an apartment that is not equipped with water meters is calculated according to the following standards (in cubic meters):

  • the rate of hot water per person per month - 4.745 cubic meters. or 4745 liters;
  • the rate of cold water per person per month - 6.935 cubic meters. or 6935 liters;
  • drainage (sewerage) - 11.68 cubic meters. or 11,680 liters (this indicator is the sum of the rate of consumption of hot and cold water per person per month without meters installed in the dwelling).

Charge rules for water supply services

What temperature should the hot water from the tap in the apartment be in a year?

The optimal temperature level of water in an apartment building for 2021 was adopted by the Government of Russia and approved by the Chief Sanitary Doctor of Russia. According to current regulations, citizens must receive hot water no colder than 60 ° C.

These regulations also take into account deviations from the norm, which are considered acceptable. Their meaning depends on time. So, at night, from zero to five in the morning, the largest deviation from 60 ° C is 5 ° C, the rest of the time, temperature fluctuations around 3 ° C are considered normal.

Taking into account the permissible changes, the optimal hot water temperature is 57 ° C during the day and 55 ° C at night. If temperature fluctuations during the day exceed the indicated indicators, then the consumer can apply for a reduction in the cost of payments for hot water supply by 0.% for each hour of the period in which a deviation from the permissible norms was allowed. In a situation where the temperature drops to 40 ° C and below, the owner may not pay for hot water supply and rely on tariffs for cold water supply.

To reduce utility bills, a special act should be drawn up, in which it is necessary to record all fluctuations in the temperature of hot water from the tap in the apartment in 2021 during the day.

Temperature standards for hot water supply

The lower bar of the temperature regime depends on the type of system:

  • open - at least 60 degrees;
  • closed - at least 50 degrees.

In an open system, the heat loss is greater, therefore a higher limit is set for them.

If the temperature of hot water in the tap is below the permissible level, this can lead to contamination with infectious pathogens and bacteria.
