Which heating is recommended for KfW 55?

Good, then the circumstances have changed.. I spoke with the [BAFA] at the beginning of the year and they said no prospects for funding for new buildings, funding for air-water heat pumps for existing properties and modernization of old buildings yes, new buildings no. If you have a direct link for that, please send me a private message. Regards

No, I'll put this in here now - according to certain definitions, you are allowed to do that.

That's fine with me too!

I am currently also working on the application for the Bafa funding in the new building - a calculated annual performance factor of at least 4.5 is the requirement. This will be difficult with an air-to-water heat pump...

Definitely - I was also assuming a brine heat pump.

There is also a subsidy for [Luftwärmepumpe], but less and lower annual performance factor.
