  • - Metal-plastic or polypropylene pipes with a diameter of 20 mm-
  • - plastic clamps, fastening tapes or special clips-
  • - corrugated pipe-
  • - concrete grade M-300 (B-22.5) or higher-

Extruded polystyrene foam, foam concrete, foam foam, mineral wool, technical plug, etc., depending on room humidity. In rooms with high humidity, select expanded polystyrene. And to ensure good sound absorption suitable mineral wool.


Along the entire perimeter of the room, place a damper(Wound) tape width of 10-15 cm. It will compensate for the expansion of the concrete screed, arising from heat. Spread polyethylene film all over the floor.


Place a reinforcing mesh (150x150 mm) from a metal rod 4-5 mm in diameter under the pipe contour. You can additionally lay another layer on the pipes.


Lay the pipes for the heating system according to one of theSchemes - a snake, a meander (double snake) or a spiral. For a more even distribution of heat, give preference to the latter two schemes. Select the step of laying pipes from 10 to 30 cm. In the area of ​​the outer walls of the building, as well as in the window and door area, reduce the pitch of the pipes. The minimum distance from the wall to the pipe is not less than 7 cm.

For fastening pipes (in increments of up to 1 m), usePlastic clamps, fastening tapes and a variety of special clips. On the heat pipe in the places of expansion joints, install a protective corrugated pipe 40-50 cm in length.

To make a concrete screed, prepare a cement-sand mortar and lay it above the pipes to a height of at least 3 cm and not more than 15 cm. It is better to install warm floors in summer, since the packaged mortar will acquire the necessary strength only after a month.


After the concrete curing has completely hardened, gradually increase the water temperature in the heating system. Within 3 days gradually go to the value of the operating mode.


Lay the finishing coat on top of the concrete screed. It can be laminate, ceramic tile, linoleum, parquet, carpet, etc. The materials must have a special designation that they are suitable for warm floors.
