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.

There are two people in our household, and we use a gas heating system. However, the mechanical ventilation with heat recovery runs continuously, 24/7.
The outdoor lighting is on all winter (8 LEDs), and 1-2 indoor lights remain on even when no one is home. Cooking is done daily. -> 2700 kWh/2017

Yvonne, how much of that is covered by the controlled residential ventilation system? Without that, we would have a reference for our consumption. The rest is quite similar—two people, six LEDs running outside at night, and something is always on inside. The cooker hood is also used every day.
Current daily electricity consumption is about 34 kWh (25 kWh for the heat pump).
Heat pump: Waterstage WSYP100DG6 / WPYA080LG
130 m² (1,400 sq ft) single-family house with basement
Domestic hot water at 45°C (113°F), 300 liters (79 gallons)
Rooms at approximately 21°C (70°F)
Outside temperature at night: -5 to -10°C (23 to 14°F), daytime: +1 to +3°C (34 to 37°F)

As mentioned before, we have similar conditions and are using about 600–650 kWh/month, so not too far off...
Household electricity: for two people, currently about 180 kWh/month, roughly 6 kWh/day.
To report the consumption for one month, we still need to wait until the end of February. The electricity meter for the heat pump was installed only at the beginning of the month.
From mid-November until January 31, we had a consumption of about 2100 kWh for the heat pump plus household use.
