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

Today, I took some time to calculate my data, which I have been recording for a year... At the beginning, daily, then of course less frequently.
Over the entire year, I actually used 3,791 kWh (kilowatt-hours) for heating an area of 250m² (2,700 sq ft).
The internal heat meter shows approximately 13,820 kWh (kilowatt-hours) of heat generated.
This results in an annual performance factor of about 3.7.
I am quite positively surprised 🙂
Our electricity meter has a network connection; what do I need for that and what information can I see?

I am currently working on calculating my plans for a photovoltaic system with storage and still have some questions about the monthly values for the heat pump and what size storage would be worthwhile.
I also calculated the figures for December; extrapolated to 31 days, we are at 15.79 kWh per day (about 490 kWh total). From October 18 until today, we have consumed 931 kWh of electricity and generated 4088 kWh of heat, resulting in a coefficient of performance of 4.39, with a heated area of 218 m² (2347 sq ft). Not bad at all.

I also did a rough calculation for December. Projected over 31 days, we are at 15.79 kWh per day (about 490 kWh in total). From October 18 until today, we have consumed 931 kWh of electricity and produced 4,088 kWh of heat, with a coefficient of performance of 4.39, heated area 218 m² (2,346 sq ft). Can't complain. That's good! Which state or region is your house located in?
