ᐅ New Single-Family Home Construction – Gas or Air Source Heat Pump + Photovoltaic System + Energy Storage?

Hello everyone,
I will be building a house in 2021/2022 and will live in it myself. It’s a 10x10 meter (33x33 feet), 1.5-story standard single-family house. The roof is a pitched roof with a 40-degree pitch, ridge direction North/South (so the roof faces East/West and can be equipped with photovoltaic panels).
Now, my question: Gas is available in the area. Which heating technology would you recommend?
Gas? Air-source heat pump + photovoltaic + battery storage? Ground-source heat pump? Or something completely different?
And who can give me advice like this without any hidden profit motives (like heating installers always pushing gas, etc.)?
Regards,
Flo

3. My decision whether to take a loan + grant or only the grant (NEW) -> grant of €26,250 will be paid out immediately No, the grant is only paid out once the house is completed and the verification has been provided by the energy consultant (EB). This applies regardless of the option (loan with repayment grant or pure grant). So you always have to finance the entire amount.

4. Register in the KfW program 461 on the website -> KfW online confirmation -> confirmation of application (BZA) number is generated You receive the confirmation of application (BZA) number directly from the energy consultant, because you then use it online with KfW to obtain

5. Specialist companies must carry out essential parts of the construction (foundation slab, shell structure, roof, windows, front door, screed, chimney) with invoices.
6. Own labor is not eligible for funding.
7. Planning and structural engineering, bathroom fittings, kitchen are not eligible for funding. For construction costs of several hundred thousand euros, this does not matter since the amount you receive only refers to €150,000 (approx. $160,000) of construction costs. This often corresponds to the finished shell. And yes, own labor is no longer accepted.

8. When everything is finished, the energy consultant comes again, inspects everything (whatever is still visible at that point), reviews the receipts and then You need construction supervision by the energy consultant. They visit intermittently to inspect the building and the installed materials. They also check what has been built using the receipts provided.

9. In the end, there is an online confirmation from KfW and a BnD number -> entered in the online portal. You receive confirmation from the energy consultant and use this to apply for the grant payment (either as a repayment grant or as cash).

Or did I understand correctly that the exact amount each trade costs is NOT important, only that the work was done in compliance?
I’m going to exaggerate this a little. If I build a shell for €100,000, roof €10,000, windows €5,000, etc., and at the end the total construction cost is only €300,000, does that not matter??? For KfW 55EE, a maximum of €150,000 (approx. $160,000) of eligible costs are subsidized. This includes shell structure, roof, windows, heating, renewable energy, etc.
Once these costs reach €150,000 (approx. $160,000), you receive the maximum possible funding. Building more expensively than anyone else does not result in additional funding.
For an average single-family home, it does not matter how expensive it is, as you should always reach the €150,000 threshold.

It is important that...
1. Photovoltaic + heat pump + 42 cm (16.5 inches) solid brick + triple glazing are installed AND
2. All these trades + the building envelope/roof are properly carried out by companies with invoices. No. What matters is that you meet the KfW 55EE standard. How you achieve this is irrelevant. And it is important that the work is performed by specialist companies.
