Hello everyone,
Does anyone have experience with a central exhaust ventilation system without heat recovery in a new build, KfW 70 standard, with underfloor heating and no radiators? (This is important because you cannot place wall or window vents above radiators to immediately mix the cold air with warm air.)
Is it recommended? If yes, what should you pay attention to? Do you notice air drafts coming from wall or window vents during the cold seasons?
I am attaching a photo from the page I read about this. The system is explained there in more detail.
Thanks in advance

The heat exchanger is still the cheapest part of this investment. Saving 1,000 out of 10,000 and risking a nice cool draft in the house? You might as well skip the controlled ventilation and just ventilate normally.
What is usually done nowadays (supply and exhaust ventilation system) typically costs between 10,000 and 15,000 € for a single-family house. The offer I received was 12,000 €. The alternative mentioned above would cost between 3,000 and 4,000 €. It could be interesting for us if there are no disadvantages, but unfortunately I can’t say that now and I don’t want to take the risk.
The disadvantages have already been pointed out to you. This is not a ventilation system with heat recovery but an exhaust air system. Those are two completely different things.
It also has nothing to do with a Mercedes; for 12,000 you will probably only get something comparable to a Golf installed. What you are considering is more like a moped.
Not recommended, no.
But certainly better than having nothing at all.
Many people also have holes made in window frames and are happy with that.
