Hello!
I'll start.
Heated area 200m2 (2,153 sq ft)
KfW 55 standard
Mechanical ventilation with heat recovery
Current outdoor temperature 6°C (43°F)
Heating energy consumption including hot water 35 kWh
Electricity consumption 9 kWh
COP 3.88

Bleeding and refilling, don’t you have a cartridge in the cellar?
Of course, the cause should be investigated, although the last few weeks have been an extreme case.
@zaba We have an appointment for consultation in 3 weeks, where 3 neighbors will participate, of course following COVID-19 safety measures :-)

So, have your pumps been running today?
Ours have been off since this morning until noon.
4 kWh consumption. I need to take a closer look at the control system.
Based on room temperature or actual outdoor temperature, it probably could have switched off around 10 a.m., but the averaged temperature (currently set to 16 hours) was still 7°C (45°F) at that time.
I haven't quite figured out yet how each control parameter influences the system.

My heat pump is still running twice a day. I checked again. The shutdown temperature is set to 10°C (50°F), not 12°C (54°F), but it isn't reached due to the cold temperatures at night. This will probably continue in March as well.
Yesterday, the total household consumption was 16.8 kWh, but with so much sun, the grid feed-in was only 4 kWh.

I’m going to get those buffer tanks and mixing groups sorted out once and for all! :p
