ᐅ Local heating network or heat pump – advice and experiences?

We are currently deciding between district heating and an air-to-water heat pump...
Our house will be built on a slab foundation according to the KfW55 standard and has a total area of 155 sqm (1,669 sq ft), including the technical room.
The district heating (biogas) costs are as follows:
Connection fee (one-time): €7,794.50
Annual basic charge: €416.50
Energy price per kWh: €0.893 – fixed price until 12/31/2031
The lump sum price from the general contractor (GC) already includes a stratified water storage tank and fresh water station.
If we choose an air-to-water heat pump (from Buderus), the GC charges an additional €12,111.
Unfortunately, we do not yet know our heating load. A budget for photovoltaic panels will probably not be available in the first five years.
Can anyone with expertise help us decide what to do or advise where we can seek consultation?
We are quite uncertain.
Thank you very much.

What kind of technology have you installed for the storage and fresh water station? The price seems very reasonable on your end...
For us, the basic fee is 416, the consumption price is 0.0893 per kWh, and the connection fee is almost 7,500—without including the house connection.
Could you maybe share some key details about the building, KfW standard, and the most recent energy consumption? I haven’t been able to find any information about that anywhere.

The annual fee is 250 euros. I believe the connection costs were around 13,000 euros.
Almost 200m² (2,150 sq ft) of living space including a separate apartment, KfW standard I think 55.
For fresh water, there is a 200-liter (53 gallons) boiler and underfloor heating, each operated by a pump, nothing more. The transfer station includes a heat exchanger, which connects to a distributor with one pump for the boiler and one mixer and pump for the underfloor heating.

Thank you – How large is your house? KfW standard? I edited the post. We built according to the lowest KfW standard because we did not apply for any subsidies and also have no ventilation system.
