Cooling with heat pump via underfloor heating?

- even though the effect is obviously amazing when you sweat and then - ah - stand in the cool air. After the initial hype became routine, we now set the device to 23 and let the rooms cool down more slowly, also we cool directly when we notice it’s getting a bit too warm (usually from 26-27), but only briefly until it’s comfortable again.

Do you have a different summer than we do? :D I think I can count the days I’ve sweated on one hand. And if it’s 20 degrees outside and 27 inside because of the window areas (greenhouse effect), I would just do a quick airing out for 5 minutes. So basically I follow your argument. And summers will get hotter again with long heat periods. But I can’t relate to your experiences from this year here in Düsseldorf :(

I think the days I have sweated can be counted on one hand.

I can agree for this year, but last year and the year before were drastically different.

Maybe not a different summer but a different house? So it has already gotten quite warm inside here a few times. Although I currently also lack insect screens everywhere for shock ventilation, and I prefer to use photovoltaic power rather than let even a single mosquito into the house. I’m allergic to it, such a bite likes to swell up to the size of a honeydew melon. :D

Shock ventilation only works if there is a bit of wind moving.

We chose the climate less because of summers like this one, but rather because of the summers still to come. Keyword 1.5 degrees in 2030, etc. I was heavily pregnant in August 2019, that was no walk in the park. o_O

May I ask how much the air conditioning cost? Did you build with Viebrockhaus?
