For our attic space (90° / approx. 30m³ (1060 ft³) / insulated / unoccupied / unheated / without windows), we need an appropriate ventilation solution.
Thank you,
yes, of course, but the Nibe air heat pump is located downstairs in the utility room. To lay the pipe, the entire duct up to the roof ridge would have to be opened. I want to avoid that.
Decentralized ventilation unit with humidity sensor, optionally with heat exchanger, and supply/exhaust air through the roof. The system must, of course, be coordinated with the ventilation concept according to DIN 1946-6 for the house.
Sure, but why include the attic in the thermal envelope at all? You end up heating the entire house including the attic and then lose the heat again through the ventilated roof tiles.
