Installation of ceiling heating

The installation example was carried out at a housing fair house in Kajaani.

  • Gross floor area 130 m²
  • Joint ceiling and underfloor heating
  • Equipment cost of the heating system 20 /m²
  • Heating costs per year ca. 500 €

  • Infraheat lamp heater
  • Infraheat underfloor heating cables as in the picture
  • Eberle room thermostats 4 pcs
  • Eberle underfloor heating thermostats 8 pcs

Vapour barrier

A vapour barrier is needed in cold roofs and for insulating moist spaces. The vapour barrier is regularly installed above the INFRAHEAT heaters, but it can also be between the cover material and the heater when heat transfer from the heaters to the cover material is ensured. In addition to plastic, a plate with plastic lamination can be used as a vapour barrier.
