ᐅ Electricity Consumption of Your Heat Pumps – Comparative Figures?

Hello everyone,
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

Unfortunately, I can only contribute to this topic later in the year.
However, I have a question related to consumption within our planning.
Our electrician suggested expanding our meter cabinet with a separate heat pump meter for 550 euros to be able to take advantage of specific heat pump tariffs. It will be a brine-to-water heat pump with deep drilling.
The house is a KFW 55 standard, with 160 m² (1,722 sq ft) of living space, and the heat pump will also be used for domestic hot water.
Is this expansion worthwhile? I feel like I can heat a lot before it pays off (without knowing the prices of the different tariffs).
Thank you in advance.

However, this is not typical, and if it really were consuming four times the specified amount, it would make more sense to heat directly with electricity and skip the heat pump altogether. Such claims are just baseless talk.
We have a KFW 55 house with 160m² (1,722 ft²), but a air-to-water heat pump. Even for us, the second meter did not pay off; with your likely even lower consumption, it probably won’t be worthwhile either. Just calculate using your local numbers and don’t forget the additional monthly basic fee. Even if you plan to install a photovoltaic system later, having two meters doesn’t make much sense.
Type of heat pump: Air-to-water heat pump – Tecalor THZ504
House size (sqm): 160
Electricity consumption: December 497 kWh, annual performance factor approx. 4.2
Hot water production via heat pump? Yes
Energy efficiency standard: KfW55 (2017)
Calculated heating load: approx. 7 kW

I will share my consumption data by the end of the year.
