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

I don’t really understand the data. Is the photovoltaic system included in the values? It looks really good with @Zaba12. Could it be that it’s already close to KFW40 standard?
Edit: What is the U-value of your building envelope, @Zaba12?I think it was 0.245. Yes, the photovoltaic system is included, but the battery storage was not available at that time.

Operating time heat pump 1:07, heat output 8.4 kWh, power consumption heating mode 2 kW per hourIs that for the last hour? That would be a COP of 4.Do you also experience frequent malfunctions? I had two defrost errors again just today.

What do you mean? I don't understand your post.What exactly don’t you understand? The energy needed to heat your houses is only about half of what mine requires. That should explain why zaba only uses a few kWh per day.Bookstar schrieb:
Do you constantly experience malfunctions? Just today, I had two defrost errors again. Is the flow rate too low?

Flow rate too low?Yes, that is the problem. But it can’t be, since everything is open.D
