Construction costs are currently skyrocketing

One can implement the controlled residential ventilation with air wells. This preheats the air in winter and cools it down in summer. Thus, one does not bring warm air into the house in summer and can still ventilate.

But it's not standard, right? Mine will only have an enthalpy heat exchanger.

Hi, You are brave: Many kitchen manufacturers often have delivery times of 6 months or more.... Best regards, Andreas

The kitchen is the first thing to clarify exactly because of the connections … and where is the electrician supposed to put the sockets, possibly spots in the concrete ceiling? Are you doing recirculation, because if not, the outlet must go somewhere.. so hurry up and start planning the kitchen …. For us, a window was even changed because of the kitchen

have it done, the kitchen fitter can at most botch something a bit after the rough installation and plastering.
It's obviously crazy that something like this costs extra.

The dear can really make a fuss with the developer. The tone in other threads was accordingly ;)

Furniture doesn't seem to be the problem necessarily, more the electrical appliances.

Isn’t that non-standard, right? Mine will only have an enthalpy heat exchanger.

Enthalpy heat exchanger? An enthalpy exchanger is designed to retain or recover a large part of the indoor humidity. The usually installed cross heat exchanger warms the incoming cold outside air on its way in with energy that the outgoing air has previously released. I didn’t know the term could be combined since in controlled residential ventilation there are two different modules. But yes, it’s not standard to cool with controlled residential ventilation. The earth-air heat exchanger is a great thing; we omitted it due to lack of space, time, and cost reasons. But basically I think the principle is great because it works passively without additional energy input.

No, of course it is not standard.

Yes, it is combinable. And it was recommended to me. And after I read into it a bit, I endorsed it.
