Hello,
I am considering which heating system I should use. For a new building of about 115m2. I would like a ventilation system with heat recovery. How much does such a system cost approximately? Or what my general contractor suggests, ventilation with exhaust air heat pump. But I have doubts about a heat pump at all. I think geothermal energy is fine, but way too expensive. How is it with an exhaust air heat pump with hot water? The orientation of the roof is east-west, does solar make any sense there at all?
Thanks in advance for tips
