@tomtom79 The heat pump is from Fujitsu,
Hydraulic unit:
    WSYA100DG6
Outdoor unit:
    WOYA080LFCA

I can manually adjust the output of the circulation pump.
The temperature difference (delta T) is 2–3°C (36–37°F).

So, the heat demand for the last 24 hours was 95 kWh, with a consumption of 30 kWh. Average temperature was -2°C (28°F). How is it looking on your end?

I don’t want to be part of this anymore. It’s depressing :p
I feel like the little chubby kid playing dodgeball.

Yesterday, with 3 heating cycles, a total house consumption of 23.5 kWh.

1st heating cycle -6.2 degrees Celsius (21°F)
2nd heating cycle -2.6 degrees Celsius (27°F)
3rd heating cycle -1.5 degrees Celsius (30°F)

The coldest average outdoor temperature during heating operation was -11.9 degrees Celsius (11°F) on 14.02.
The electric heating rod activation starting at -12 degrees Celsius (10°F) has proven effective. 🙂

The electricity consumption of @Zaba12 is really quite impressive.

This is partly just household electricity with two people working from home, both children at home, etc.
