Determine the running costs for a house

Therefore, it makes sense to consider household electricity as such and everything else separately (e.g. as "heat" or hot water etc.).

The controlled residential ventilation consumes electricity for about 80 euros/year in our case (measured with an "intelligent" socket).

Thank you very much for the hint/tip. Do you also have a passive house? If yes, how large is it and how many people live in it (to classify your 80€/year for the controlled residential ventilation)?
