Underfloor heating air-water heat pump. House too warm when the sun shines

and where did you see the pressure drop??

We have a display directly on the system, see picture.

Thanks, I need to take a look.

I have a hose hanging in the technical room specifically for this, and during the briefing I was shown how and where. Interesting, and obvious in hindsight: first release the air from the hose, only then fill the system. Otherwise, the air from the hose is unnecessarily pushed into the system.

Interesting, in retrospect quite self-explanatory: first release the air from the hose, only then fill the system. Otherwise, air from the hose is unnecessarily pushed into the system.

We didn't get any explanation at all, no idea if there is a hose anywhere. :-(

Tell me everyone, what heat pump electricity consumption do you have per day? Sure, at the moment it is cold, last night it was -6°. But yesterday afternoon with great sunshine it was 5°. We currently have between 28 and 35 kWh per day of heat pump electricity. How is it with you? Is that a lot or normal for these cold days?

We had the following consumption from yesterday to today within 24 hours:

- WP 50.93 kWh
- WW production 48° continuously switched on as needed from 9 am - 10 pm
- Circulation from 4 am - 8 am and 6 pm - 9 pm
- Heating curve slope 0.3 / level 0 set temperature 21° / room temperature ACTUAL 22.5°
- heated area 260m²
