KfW55, 165m²+basement, single-family house (room temperature approx. 22-24°C) Location BW, 940m above sea level Average temperature January 21 at 2m: -2.3°C (ice days 20, frost days 27) Heat pump consumption: 506 kWh
You hear it, if anyone can say something about it I would also be interested.
January according to the internal meter 2606kWh heat quantity for heating and hot water. Electricity according to the internal meter 542kWh (only one household meter, no separate one for heat pump, maybe I will retrofit one). Total electricity for the house in January 920kWh.
Single-family house moved in in Nov. 140sqm living space. + 78sqm basement in thermal envelope. About half of that heated to about 18 degrees. Energy Saving Ordinance house with insulation values just around KFW55. No idea what I should compare this to and how to evaluate it. At least not a total disaster I think...
It’s a nice example after all. Size and standard are very similar. I just don’t heat my 32sqm of the 71sqm basement. I already wrote it last week. If the return flow sensor had been calibrated by the end of December, there would have been about 750kWh total electricity on the meter yesterday. This is our 2nd winter.
Still in the middle of it. That would also be my approach. Currently, it's pretty much fine despite some rooms being partly turned off. The ones that are cooler now don't need to be warmer. But there is now zero flow there. Presumably, they are now being heated through the adjacent rooms, which partly have 18 degrees. The question is, now should I just leave it as is or slightly turn up the cooler rooms and then lower the others a bit in return.

Yes, and I saw the excerpt from your energy certificate... You have significantly better values than I do. In terms of insulation values, you are more towards KFW40, if you can put it that way.
So I think it's okay with some improvement potential + first-winter effect.
Edit: Whoever wants and has it at hand can add values from the energy certificate:
Final energy demand 17kWh/(Qma), primary energy demand 30.6 kWh/(qma) Ht 0.282
