ᐅ House Electricity Consumption – Usage Figures for Comparison

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.

The first question is: How is the 30 kWh distributed between heating and household electricity?

Interesting. We have a gas heating system, so I don’t have much to add on that. Otherwise, the appliances running 24 hours are the refrigerator, freezer, and ventilation system. Over the past 1.5 years, our average consumption has been around 8 kWh per day. It’s a household of two people, both fully employed, and we still cook in the evenings.

Yes, both

The question is HOW?

5 to 25 can be answered differently than 25 to 5...

I would estimate that about 5-8 kWh per day are used for household electricity (including the central ventilation system, which runs continuously). The peaks in consumption are clearly related to heating.
