Hello everyone,

I need to reach out to the forum because I would like to get your opinions and advice.

We (2 adults with 2 small children) have been living for two years in a single-family house with a self-contained apartment (Einliegerwohnung). This apartment has been rented out for one year (2 adults with a baby).
Our house is equipped with a ground source heat pump (Nibe 1245 PC). It provides hot water, heating, and passive cooling through the underfloor system.

The main electricity meter shows 18,000 kWh.
This seems extremely high to me, and I cannot figure out where such consumption could come from.

Could the meter from the energy supplier be faulty?
Could a device, for example the heat pump, refrigerator, stove, etc., be malfunctioning and therefore drawing more electricity?

I am still quite puzzled.

Best regards
S

Thanks, everyone!!!

It seems like a lot of work to properly set up my system.
It's unfortunate that the installer doesn't do this directly... at the very least, Nibe customer service should handle something like this, right?!
