EcoAir 614M heat pump from Giersch experiences

Why not?

I am renovating according to KFW 55 guidelines. There is a 40% discount on everything except pet food (and a few small things) and I can work more flexibly because, for example, there are no requirements for the heat pump (efficiency, electricity meter, or whatever).

Aha. Thanks for the explanation. I just find it strange that you don't get any funding because of one degree below zero more. And I can't remember when it was last minus 14 degrees here.
