Yes, those were MAP. Correct, they cannot be combined and thus it should actually be worthwhile to quickly complete BAFA + KfW 153...
I then inquired again at KfW. Here is the answer:
Dear Ms. XXX,
Dear Mr. XXX,
Thank you very much for your inquiry.
We are pleased to confirm that the funding in the market incentive program of BAFA may be combined with the new federal funding for efficient buildings (BEG WG).
Please note the following:
The investment costs that you apply for the heating system in the BAFA funding are not eligible for funding in product 153 and in the BEG WG. Costs exceeding the BAFA grant must be financed elsewhere.
Important for you:
If the installation of an EE heating system is already or has already been subsidized elsewhere, you cannot apply for the EE class and Efficiency House 40 Plus funding levels.
Further information on the BEG WG grant variant can be found here: KfW/461
Need additional information?
Call us! You can reach us Monday to Friday from 8:00 a.m. to 6:00 p.m. at the toll-free service number 0800 539 9007.
Best regards

Does this now mean that for a KfW 40 Plus house, the combination
BAFA old + KfW 40 Plus does not work,
but
BAFA old + KfW 40 NH does?
