Your current heating consumption

Not everything that limps is a comparison.
I have alone(!) 40% of the heating + hot water consumption from the period October-January in January ("instead of" 25%). Then, with your given 2500 for the 4 months, that is by the way 1080kWh for January with similar conditions and thus just as much as Bautraum!

Hmm, for one month, even 1000 is quite a lot.

So this statement does not match your data, unless you mean that your heating costs are also high!

I did write... that is rather a lot... However, it is distributed a bit more evenly with us and we have between 23 and 24 degrees in the living room and a rather very high (hot) water consumption

How much did you have in January? More or less than the questioner? Because I deduce more from the numbers, so that he used less than you (in absolute terms).

Please forgive my silly question... just blame it on me being a woman
There are two numbers on the electricity meter for the heat pump: N and D
When I calculate the electricity consumption, do I add both together?

I’d have to check, but I think less. However, I believe we only had a maximum of -12 degrees. And the heat pump just becomes more and more inefficient the lower the temperatures.

Yes, add them together
