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.

Really affordable... At our price, 18000 kWh is quite a lot... I could almost heat with gas instead.Plus heating maintenance, plus chimney sweep, plus a huge unit in the basement. If you have access to district heating, that is currently the most comfortable and sustainable solution.
Well, first we have to pay a connection fee of 7,800 (7,800) ... Then, according to the technical specifications sheet (TAB), a storage tank plus a fresh water station for 5,600 (5,600)...
So, the basic costs amount to 13,400 (13,400).
Ongoing costs are a 416 Euro (416 USD approx.) basic charge plus just under 9 cents per kilowatt-hour...
Considering your consumption and our price, I estimate heating costs of 2,023 Euro (2,023 USD approx.) per year, which I find clearly too high for a new house...

But how much does a heat pump plus storage tank cost? Or a gas heating system?
Then you have to calculate the annual running costs: electricity for the heat pump, gas for the gas heater, chimney sweep, chimney maintenance, servicing, etc.
With district heating, just electricity for the pumps... that's it.
For us, the connection cost was also around 13,000 euros (including the transfer station)
And you would need a hot water boiler in any case.
