Hello,
we are currently renovating a single-family house built in 1956 and replacing the old gas heating and radiators with a heat pump and surface heating. The plan is to install underfloor heating in some areas and wall heating behind clay plaster in others.
Our heating installer offered us:
- For the underfloor heating, "Athe Fix" including a 40 mm (1.6 inch) ATHE-VUNO cement screed on top
- For the wall heating, "ATHE F-Module heating for floor, wall, or ceiling"
“Cover foil with a thickness of 150 µm
ATHE-F module heating element in pre-determined and prefabricated dimensions,
Heating pipe square profile measuring 12 x 12 mm (0.47 x 0.47 inch),
Total height at the manifold 24 mm (0.94 inch)
Edge insulation strips, sound insulating and able to accommodate the thermal stress of the screed (longitudinal expansion)
If required: Additional thermal and impact sound insulation according to energy saving regulations.”
We recently visited a building materials store to inquire about clay plaster. The employee there was quite skeptical about the wall heating; on one hand, they said that despite an external thermal insulation composite system (ETICS/planning permission: external insulation) on the house façade, additional insulation with wood fiber or similar should be installed between the wall heating and the masonry. On the other hand, they emphasized the importance of a “vapor-open” system, which they believe is not the case here due to the cover foil.
As laypeople, we are now unsure whether to fully trust our heating installer or if there might be some validity to their concerns.
Do you have any insights? Has anyone had experience with the “ATHE F-Module” system?
Thank you very much!
