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

Still looks pretty good.
This part is really efficient right now, I'm surprised.

Is TA the outside temperature?

Yes, averaged over 24 hours

Looks good.
Your heat pump wasn’t modulating, right?
A 5-hour heating phase at that temperature is really impressive.
Do you also have the heat output data?

It is not modulating. To calculate the COP, I would need to reset the heat energy data. The COP is around 4, at least that’s what I determined at the beginning of the month based on a 24-hour period.

I also find it surprising that the heating phase lasts only 5 hours.
