Hello everyone,
We are planning to build a KfW 70 house and would like to install an air-to-water heat pump with underfloor heating as well as a photovoltaic system.
We would appreciate your professional opinion on the required size of the heat pump. The house will have approximately 140 sqm (1507 sq ft) of living space.
Additionally, we would like to have a fireplace in the living room.
I am unsure whether we definitely need a mechanical ventilation system in this house to prevent mold growth.
Is there really a risk if, for example, we go on vacation and do not ventilate regularly, or is this more of a concern with passive houses?
Thank you in advance for your help!
Best regards,
Silke

...The house is a KFW70 Passive House.... This term is probably a personal invention or just marketing hype from an eager salesperson! Best regards
