KfW40 with oil heating probably won’t work anyway. Is he messing up the calculation? You need a heat pump anyway, so it should be classified under the 300 program. Otherwise, there is no possibility of funding.

The heat pump is clear and necessary, that is clear, but I am basically also renovating the existing building and replacing the current oil heating system. It would probably be worth trying to additionally apply for the 458; the requirements are not clearly formulated. Does anyone have similar plans, or has already applied?

You are building new - KfW 300. Then there is no possibility to get 458 for the same property. Moreover, no energy consultant in the world would create a BzA for you in the first place because they are not allowed to, and thus you wouldn't even get to the application stage.

Then you would also have two heat pumps. One for the new building and one as a heating system replacement.

The use of funds and disbursement for the KFW 300 loan is for the efficiency house without heating, I can manage that in terms of invoicing. Roof, insulation, walls, etc.

The use of funds for 458 I can demonstrate and confirm with the expansion of the old heating system (proof) and the invoice for the new heating system. I do not see it as hopeless.

Without heating, no. The energy taxation does not allow that. Have fun. And don't cry if it doesn't work as expected.
