We currently have a KfW 55 standard with about 20 to 25 kWh per day. Just two more days, then the December value will be finalized and the billing will be done 😀.

Please specify whether you mean electricity or generated heat. Ideally, both. Electricity alone does not provide much information without the value of the heat produced.

For me, it was the electricity!
I need to check the heat generated at the heat pump.

Yes, I also have electricity. I will check the heating starting tomorrow.

Unintentional test,
The living area otherwise normally 23°C (73°F), yesterday aired out and during that set the thermostat to 0 and forgot about it,
today at 9 a.m. went to air out, the tiles cold to the touch and the room at 21.7°C (71°F), outside 0°C (32°F),
I find the house’s heat storage capacity impressive.

Here are my figures for 2020:

- KfW40 new build using timber frame construction
- Living area: 143 m² (1540 sq ft) + approx. 70 m² (750 sq ft) basement, of which 15 m² (160 sq ft) is storage and 10 m² (110 sq ft) is a technical room, unheated
- Underfloor heating throughout. In the main bathroom approx. 80 m (260 ft) of pipe as wall heating in drywall construction
- Standard outdoor temperature (-16 °C / 3 °F)
- Month/year of initial commissioning (05 / 2018)
- Also produces hot water / 44 °C (111 °F) for 2 persons
- Heating limit (12 °C / 54 °F)
- Room temperature approx. 22 °C (72 °F)

- Heat demand: 8770.20 kWh
- Electricity demand: 2273.10 kWh
- Annual performance factor: 3.86

With that, I wish you a happy new year.
