ᐅ Your Gas Consumption for KfW 70/55 Standards

Hi,

The question is already in the subject line. To make a proper comparison with the consumption of an air-to-water heat pump, I’m interested in your consumption figures for gas heating. Of course, many factors come into play, but to get a rough idea, it would be helpful to know what consumption you have for different building sizes and according to which KfW standard.

Thanks

It makes no sense to compare this because no one would install both a heat pump and a gas heating system at the same time.

Where the energy comes from and what it costs is just a calculation exercise and is independent of the energy source.

Additionally, the energy demand of a specific KfW 55 house could be higher than that of another KfW 70 house, regardless of whether the house uses gas or a heat pump.

As mentioned, the goal is to get an approximate feel rather than make an exact comparison. It goes without saying that this has worked.

Hi!

And what kind of feeling do you expect from completely arbitrary values?

Thank you, Thorsten!
