KfW70 with gas condensing boiler and solar is definitely not possible

Oh, I see... About the topic "let's see what happens." I had already confronted him once with a similarly unusual judgment after an appointment with an energy advisor from the Verbraucherzentrale (which was my first point of contact on this topic). Answer: "That can't be!" Well, it's just that simple then.

Unfortunately, the advisor from the VBZ was as much of an expert in the field as I was, which shocked me, but given similar experiences with the VBZ on other topics, it did not surprise me. But the consultation was also free, what can you expect.

By the way, you can access the application form on the KFW website and enter the energy data of the house in the first steps. It immediately shows whether the KfW requirements are met. Only then are personal data, etc. requested.

That sounds highly interesting! I keep searching and searching, but I can't find it.

if you search for "KFW 153 online confirmation," you will find this web application. HOWEVER, it is now protected by a login. I was still able to experiment with it a few months ago.

Sorry!

Found!

Unfortunately, registration is only possible as a registered energy efficiency expert.

One more note regarding the post created by Bauexperte: For KfW 70, no special construction management is required - only the application at the beginning and the certificate at the end. Only with KfW 55 does the effort increase, which is probably why the subsidy is larger there.
