In this article we'll discuss the device patty underfloor heating on the ground in my home, as well as the installation of underfloor heating directly themselves. Did it all himself, his wife partly helped spread a film materials and laid extruded polystyrene.

It was decided the unit underfloor heating on the ground to leave on the last stage of the construction of the box, plastering walls and installation of entrance doors.

Backfilling of sand was already pretty rammed as precipitation during a finding without a roof at home and work in the process of construction of the house. I did not pull the rough screed on the sand, as it is to anything, and immediately proceeded to the sealing device.

  1. Aligning sand rule beacons, laid on a layer of polyethylene film 150 microns. in two coats with a 10 cm overlap.
  2. On the film a groove in a groove performed styrofoam packing density of 35 kg. / Cu.m. and 30 mm thick.
  3. Polystyrene bed with a 15 cm overlap. shaped membrane dense polyethylene (served as additional waterproofing), as well as via the profile raised membrane welded mesh.

Since the heating system I - collector (radiation), then on top of underfloor heating laid pipes to radiators in isolation.

The thickness of the screed left an average of 10 cm. (9 to 11 cm.), As share in the following articles.

When installing underfloor follow:

  • loop pipe length of F16 should not exceed 80 m .;
  • under kitchen furniture, wardrobes, refrigerators - do not use the floor heating;
  • every room in the doorway separate the expansion joints of the same damper tape, as well as share the room expansion joints, which make up more than 30 square meters;
  • pour subfloors working pressure in the system of floor heating (1.5 - 2 bar).
  • before pouring the screed is required to spend a molding system, at least triple the operating pressure (6 - 8 Bar).

I hope that the material you came at the right time! Successful construction!
