Decree of the Gosstroy of the USSR dated 01.01.2001 No. 75).

The heat energy metering unit is equipped at a heat point owned by the consumer.

Individual heating points (hereinafter referred to as ITP) must be built into the buildings they serve and located in separate rooms on the ground floor near the outer walls of the building. It is allowed to place ITP in technical undergrounds or in the basements of buildings and structures.

Buildings of detached and attached ITPs should be provided as one-story, it is allowed to build basements in them to accommodate equipment, collect, cool and pump condensate and sewerage facilities.

Separately standing ITPs are allowed to be underground, provided:

Absence of groundwater in the area of ​​placement and sealing of inputs
engineering communications to the building of the heating point, excluding
the possibility of flooding the heating point with sewer,
flood and other waters;


Ensuring gravity drainage of water from pipelines of thermal
item;

Ensuring automated operation of thermal equipment
point without permanent service personnel with emergency
alarm and partial remote control with
control room.

According to the explosion and fire hazard, the premises of heat points should be classified as category D.

Heat points are allowed to be placed in industrial premises of categories D and D, as well as in technical basements and undergrounds of residential and public buildings. At the same time, the premises of heat points should be separated from these rooms by fences (partitions) that prevent unauthorized persons from accessing the heat point.

In the premises of heat points, the finishing of fences with durable, moisture-resistant materials that allow easy cleaning should be provided, while the following work should be performed:

Plastering of the ground part of brick walls;

Jointing of panel walls;

Ceiling whitewashing;

Concrete or tiled floors.

The walls of the heating points must be covered with tiles or painted to a height of 1.5 m from the floor with oil or other waterproof paint, above 1.5 m from the floor - with adhesive or other similar paint.

From the heat points built into buildings, exits should be provided:

a) with a length of the premises of the heating point of 12 m or less and
its location at a distance of less than 12 m from the exit from the building to the outside
- one exit to the outside through the corridor or stairwell;

b) if the length of the premises of the heating point is 12 m or less, and
its location at a distance of more than 12 m from the exit from the building - one
independent exit;

c) if the length of the premises of the heating point is more than 12 m - two
exit, one of which should be directly outside, the second -

In underground, detached or attached heat points, it is allowed to place a second exit through an attached shaft with a hatch or through a hatch in the ceiling, and in heat points located in technical undergrounds or basements of buildings - through a hatch in the wall

Doors and gates from the substation must be opened from the premises or building of the heat substation away from you.

Dimension doorway ITP should provide free passage of personnel.

All passages, entrances, exits must be lit, free, safe for movement.

The passage between the equipment, pipelines must ensure free passage of personnel and be at least 0.6 m. Transition platforms must be arranged through pipelines located at or above the floor level.

The height of the premises from the mark of the finished floor to the bottom of the protruding floor structures (in the light) is recommended to be at least 2.2 m.

When placing IHS in the basement and basement rooms, as well as in the technical undergrounds of buildings, the height of the rooms and free passages to them is at least 1.8 m.

For water drainage, floors should be designed with a slope of 0.01 towards the drain or catchment pit. The minimum dimensions of the catchment pit should be at least 0.5 x 0.5 m in plan, with a depth of at least 0.8 m. The pit should be covered with a removable grate.


In heating points, open laying of pipes should be provided. It is allowed to lay pipes in channels, the top of the overlap of which is combined with the level of the finished floor, if these channels do not allow explosive or combustible gases and liquids to enter the heating point.

Channels must have removable covers with a unit weight of not more than 30 kg.

The bottom of the channels should have a longitudinal slope of at least 0.02 towards the catchment pit.

For maintenance of equipment and fittings located at a height of 1.5 to 2.5 m from the floor, mobile or portable structures (platforms) should be provided. In cases where it is impossible to create passages for mobile platforms, as well as for servicing equipment and fittings located at a height of 2.5 m or more, it is necessary to provide stationary platforms 0.6 m wide with fences and permanent stairs. The distance from the level of the stationary platform to the ceiling must be at least 1.8 m.

The minimum distance from the edge of the movable supports to the edge of the supporting structures (traverses, brackets, support pads) of the pipelines should ensure the maximum possible displacement of the support in the lateral direction with a margin of at least 50 mm. In addition, the minimum distance from the edge of the traverse or bracket to the axis of the pipe must be at least 1.0 Dy (where Dy is the nominal diameter of the pipe).

The distance from the surface of the heat-insulating structure of the pipeline to the building structures of the building or to the surface of the heat-insulating structure of another pipeline must be at least 30 mm in the light, taking into account the movement of the pipeline.

The laying of the water pipeline must be carried out in one row or under the pipelines of the heating networks, while the thermal insulation of the water supply must be performed to prevent the formation of condensate on the surface of the water pipes.

In heating points, the supply pipeline must be located to the right of the return pipeline (along the flow of the coolant in the supply pipeline) when laying pipelines in one row.

For heat points, supply and exhaust ventilation should be provided, designed for air exchange, determined by heat emissions from pipelines and equipment. Estimated air temperature in working area in the cold season should be taken no higher than 28 ° C, in the warm season - 5 ° C higher than the outside temperature.

In the premises of heat points, it is necessary to carry out measures for the destruction of insects, rodents (disinfestation, deratization).
