With us, the air-to-water heat pump was often offered with an additional cost of around 10k. It therefore seems to vary from provider to provider.

Nowadays gas without a solar share is no longer an option anyway. It is the minimum requirement for the Energy Saving Ordinance.

Including controlled residential ventilation? Or without?

That is not correct. We even build Kfw55 with gas and without solar. But with a good building envelope.

So you want to say you are building a Kfw55 only with gas, without solar thermal support and without controlled residential ventilation with a building permit after 01.01.2016

So getting below 51 for the PE is already not easy. But getting below 35 for the PE ops:

What kind of envelope is that?

No, we naturally have a controlled residential ventilation system, otherwise in my opinion that is definitely not possible. We were only able to save on the solar we did not want through a somewhat improved building envelope.
