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

@Zaba12 When did you "disconnect" the basement?
And haven’t you been using your fireplace in the last few days?
The energy consumption looks really good, but keep monitoring it for the next few days. The moment you disconnect the basement, the consumption will naturally drop at first. However, the basement will gradually cool down. This causes the heat transfer from the ground floor to the basement to increase again, and the "consumption of the ground floor" will suddenly rise if you want to maintain the temperatures (on the ground floor). (Unless you insulated the transition between basement and ground floor.) This effect takes a few days; it doesn’t happen overnight.
Nonetheless, I think this is a very good consumption rate.

The energy consumption looks really good, but keep monitoring it over the next few days. As soon as you disconnect the basement, the consumption will naturally drop at first. However, the basement will gradually cool down. This causes the heat transfer from the ground floor to the basement to increase again, and the "ground floor consumption" will suddenly rise if you want to maintain the temperatures on the ground floor. (Unless you insulated the transition between basement/ground floor). This effect takes a few days; it won’t happen overnight.
Nevertheless, I think this is a very good consumption. The basement has been off since 01.01.
A different question: At what temperature does your heat pump stop heating? I’ve set it to 13°C (55°F) for now, which is the average over 48 hours.
Who has it set even lower, and what has your experience been? At least on the ground floor, we have a very high solar gain. The upper floor doesn’t get as much, but downstairs it already gets very warm in full sunlight without lowering the external blinds. That’s not a problem for me, at least when the underfloor heating is turned off.

We currently consume about 25 kWh per day, of which approximately 16 kWh per day is used by the air-to-water heat pump for 50-60 kWh of heating and 6 kWh for hot water. Photovoltaic output is currently zero, as we have between 15-30 cm (6-12 inches) of snow covering the panels. Temperatures are rarely above -1°C (30°F) and can drop to -10°C (14°F).
