That you don't want it is your decision. But that doesn't mean it is economical. Since I had a photovoltaic system planned anyway, a heat pump is the logical consequence.

Nordlys. Do you feel like continuing to argue with reasons or do you just want to mantra-like repeat that KfW55 is all nonsense?

I have a bit of the feeling that you have decided against KfW and are not entirely sure yourself whether it was the right decision and why you actually made it. Now it has to be legitimized by converting all the undecided.

If that was really your motive

...we don’t need to discuss further.




The air-to-water heat pump is not included. Is listed separately with 5000.
And the 35% is not always available. Depends on the model. (Seasonal performance factor etc.)

Currently, a (small) storage system only pays off with KfW40+.

I can only say that with us, there was also an additional cost of around 20k for KfW55. We easily recouped this solely through the 18k repayment grant and interest savings during the 10-year KfW 153 term. So we don't even have to rely on saving energy with it. Everyone has to calculate it for themselves. Those who generally already get an interest rate below 1% from the bank should take a closer look.

Anyone who nowadays does not build at least to KfW 55 standard is building an old building.

It's that simple.
