We are building a KFW 55 house, and the heating system will be an air-to-water heat pump.
The underfloor heating has now been installed (according to the heat load calculation).
I am surprised that the distance to the balcony doors is almost 30 cm (12 inches), meaning no pipes were laid in these reveals. Could this cause problems? Thermal bridging? Will I have cold feet when standing there?
Until now, we have always used gas, so sorry if my questions seem basic. However, I have never lived with such a low supply temperature in a new building before.
If this is problematic, then the question is how it can be fixed, since the underfloor heating has already been installed. The question is to what extent it can still be adjusted.
We wanted to be present during the installation, but someone just came by in the evening without notifying us.

Maybe you only notice it at 5cm (2 inches), or maybe at 15cm (6 inches), who knows?
However, it shouldn’t be too close either, because you don’t want to heat the door or windows (= weak points).

I’m not exactly sure how it was in our case, but in a KfW55 house, the edge areas don’t cool down excessively. Also, people usually don’t stand there, and depending on the floor type (wood, tiles, etc.), you won’t really notice much difference with the current supply temperature of max. 35°C (95°F).
I’d say the heating technician could have added one or two more loops, but probably wasn’t interested anymore.
I would raise this issue with them, but I don’t see a major problem here.
Good luck.
