At Rensch-Haus, KfW 40 houses come standard with an internal heat pump featuring central ventilation and fresh air heating. For an additional cost, an external heat pump with underfloor heating is also available.
Does anyone have experience with fresh air heating?
I am familiar with underfloor heating; it is somewhat slow to respond but works perfectly.
The sales representative recommends the fresh air heating, even though it is less expensive.
I would be very grateful for any experiences.
Thank you!

In a passive house, an air heating system is definitely acceptable. KFW40 is already quite close to that standard. If the heating load and climate zone are appropriate – why not. With KFW55 and lower standards, it becomes more challenging – and the forums are full of discussions about that.
