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

I don’t know if it’s because of age or the underfloor heating, but since we’ve been living here, I’ve become more sensitive somehow. When I wake up in the morning and the living room is only 21°C (70°F), I notice it immediately, and 23°C (73°F) feels way too warm right away.

It might be a very subjective feeling. In the “old house,” which was uninsulated from the 1980s with radiators, I was constantly adjusting the radiator valves. There’s no way the temperature was that stable back then. Now, I notice every 0.5°C (1°F) change, both up and down, very clearly. Maybe it’s because the more constant something is, the more noticeable any variation becomes.
01.10. – 11.03. 1796 kWh of electricity used for the heat pump. Could be less, but the COP is still only 4.2.
200 m² (2,150 sq ft), KFW55 standard, controlled residential ventilation, 4 occupants. Ground source heat via probe.
Target indoor temperature 22°C (72°F). Achieved within ±0.5°C (±0.9°F).

Target indoor temperature is 22°C (72°F). Maintaining ±0.5°C (±0.9°F) works well.I have little sympathy for that consumption :p (you wrote, unfortunately).I hope to report similar consumption next year.
Cross-comparison:
Oct 1 - Mar 1:
1050 m³ (37,100 ft³) gas => approx. 400-450€
No, I’m not part of the gas lobby :p
But I find this thread and the discussion very interesting.
@guckuck2: Do you remember the additional cost of geothermal compared to an air-to-water heat pump?
Does it also make sense to pair photovoltaic with geothermal? (financially, not ideologically :p)
