Hello dear forum community,
We are planning to build a house soon, for which the builder is relying on a greywater heat pump for ventilation and dehumidification.
Primarily, air will be drawn from the guest toilet, bathroom, and utility room and used for hot water production. Air from other rooms flows in to replace it, allowing for some air exchange. Fresh air is also intended to be supplied to the living spaces. I assume this will require wall openings in the living areas to the outside, as otherwise, in my opinion, not much air will flow in.
What do you think? Is this a good operating principle and fairly common for a house of about 130m² (1400 sq ft), or is it nonsense? Is the ventilation achieved this way sufficient to effectively prevent mold growth?
Thank you very much for your answers.
