ᐅ Single-family house – 18,000 kWh in two years – what could be the issue?

Created on: 17 Aug 2020 16:38

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

We (two-family house) manage the utility costs ourselves. Each unit has 3,000 kWh household electricity and a 4,000 kWh pump. That makes 20,000 kWh in 2 years! It should not be forgotten that the pump heats both the hot water and the heating. Each apartment has its own meter provided by the utility company. The pump also has a meter (peak/off-peak), and the consumption here is divided via the heat meter in the apartment.
