ᐅ Air-to-water heat pump, mechanical ventilation with heat recovery?

Hello!
We are currently planning a single-family house with 172m2 (1850 sq ft) of living space here in the north, working with a well-established general contractor.
I want to build according to the KfW 55 standard and take advantage of the related funding.
I was shocked by the quoted all-inclusive price of 27,965 EUR for the following system:
Viessmann - Vitocal 200-A + (air-to-water heat pump)
Viessmann - Vitovent 300-F (central controlled ventilation with heat recovery)
They credited me 2,000 EUR for a gas condensing boiler.
My questions:
1. Is this a reasonable price? As I said, I was quite surprised.
2. Would a gas condensing boiler combined with solar thermal system plus controlled supply and exhaust ventilation with heat recovery also meet the KfW 55 requirements? (Additional insulation is in place)
I urgently need your advice.
Thanks in advance!

Our air-to-water heat pump with controlled ventilation, underfloor heating, and installation cost almost exactly 30,000 (currency). However, we upgraded to geothermal heating for 35,000 (currency). We received a BAFA subsidy of 4,500 (currency). So for 500 (currency) more, we got geothermal heating 😀
Yes, yes, the extra charges are where the money is made 🙂
With all due respect, the container costs somewhere between 7,500 and 8,500 euros depending on the size. And that’s still not at the bottom end of the price range. It’s similar with the controlled residential ventilation system.
And the €2,000 (about $2,200) credit for the gas stove is completely off. 😱 I would seriously be interested to know how they intend to prove compliance with the 2016 Energy Saving Ordinance, or, since it’s a BT, is the permit already very old?

For the simplified procedure, a gas condensing boiler, the required number of solar collectors according to the standard, and a ventilation system with heat recovery are sufficient for KFW55. Additionally, the insulation standards must be met. So, KFW55 does not fail due to the gas condensing boiler, solar system, or controlled residential ventilation.

I’m still undecided about whether to go with an air-to-water heat pump or not. It means an additional cost of 11,900 EUR (about 12,950 USD) that I would have to invest here, considering I get a 2,000 EUR (about 2,175 USD) grant and save 2,000 EUR (about 2,175 USD) on the gas connection.
That means I would need to save 11,900 EUR (about 12,950 USD) in costs over the next 20 years compared to gas for it to be worth the investment, if I’m calculating correctly? Is that realistic? (About 600 EUR (about 650 USD) savings per year on average?)
Can I still apply for the BAFA funding in addition to the KFW55 loan 153?

Of course, you could factor in the BAFA subsidy to make it seem less expensive. There are already threads in this forum with quite detailed calculations on this topic. Depending on the calculation and individual situation, the results vary significantly. However, the general opinion tends to be that additional insulation or more expensive technology does not pay off for many.
