Hello,
I know there are many factors affecting electricity consumption, so it might be a bit of guesswork. Still, I want to give it a try.
We have a ground-source heat pump (deep drilling). We heat about 170 sqm (1,830 sq ft) with it and don’t have large electricity consumers like an aquarium, etc. Our house meets the KFW 55 standard.
Currently, we use roughly 30 kWh per day on average for everything (heating and regular electricity). We rarely have temperatures below freezing at night. When I calculate the consumption over 30 days, it comes to about €250 per month in winter. Of course, consumption is naturally lower in summer.
Does anyone have comparable numbers? We just moved in in October, and I’m wondering if the heating system is working properly (efficiently) and if the output from the ground loop is as expected.
Looking forward to your feedback.

We also live in Baden-Württemberg. Our house is KfW-55 standard, about 165 m² (1776 ft²), currently two working adults. We cook every evening, and my wife enjoys baking. The house is generally warmer than usual in all rooms (a luxury). We have an air-to-water heat pump with controlled ventilation and heat recovery.
The household consumption is around 175 kWh, with the heat pump using about 640 kWh in total. Costs, excluding the basic fee, are about €45 + €135. The advance payment is a bit higher, but it’s nice to look forward to potential refunds.

By the way, my heat pump shows the following annual performance factors:
Heating: 4.8
Domestic hot water: 3.3
Overall: 4.4Please consider only the entire year and use standard temperatures.
