When searching for reference values for my heat pump, I couldn’t really find much. That’s why I thought of starting this thread, so anyone interested can share their data. I consider the following parameters relevant for comparing values:
Type of heat pump (including exact model, if possible)
House size (sqm)
Electricity consumption
Hot water production via heat pump? Yes/No
Energy efficiency standard of the house (e.g., KFW55, KFW70, etc.)
If there are other values I haven’t considered yet, please feel free to add them.
I hope that by comparing these values, we can get a rough idea whether a heat pump is working well or consuming too much electricity. I understand these can only be approximate figures – it also depends on how the heating is used and how much hot water is consumed.
My values are as follows:
Type of heat pump (including exact model, if possible): Air-to-water heat pump WWP L15 ARS
House size (sqm): 190
Electricity consumption: December 2017 – 745 kWh
Hot water production via heat pump? Yes
Energy efficiency standard of the house (e.g., KFW55, KFW70, etc.): KFW55
Best regards,
Oliver

readytorumble5 Jan 2018 07:18Type of heat pump: Ground-source heat pump with horizontal collector. Viessmann Vitocal 200-G
House size (m²): 160
Electricity consumption: December 439 kWh
Domestic hot water supplied by heat pump? Yes
Energy efficiency standard: Energy Saving Ordinance 2014
However, this comparison is not representative.
Indoor temperature, outdoor temperature, etc.
For example, we live in the Eifel region at about 550 meters (1,800 feet) elevation, where it is relatively cold. For us, 20°C (68°F) in the living areas and 17°C (63°F) in the bedrooms are sufficient.

Type of heat pump: Air-to-water heat pump – Tecalor THZ504
House size (sqm): 170
Electricity consumption: December 612 kWh (including ventilation, hot water, control, etc.)
Hot water production via heat pump? Yes
Energy-efficient house standard: KfW55 (2016)
Calculated heating load: approx. 7 kW
For example, we live on the Swabian Alb at about 950 m (3100 ft) elevation, where it is quite cold (!). Indoor temperatures are 22–23°C (72–73°F) in all rooms.

Regarding ground source heat pumps, I found posts online where the electricity consumption was four times higher than anticipated. That would drive me crazy.
