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.

Yes, they can require a connection, but not the consumption amount. However, every contract with district heating expires after some time. Additional heating systems cannot be prohibited. The municipality cannot mandate the energy standard, (federal law applies here).You don’t seem to be from the real estate industry. By now, the municipality can regulate almost everything (at least in new development areas). It is now even legally required under the Building Code to consider climate protection and include various points in the development plan. What cannot be regulated there is dealt with through urban development contracts, land purchase agreements, and private written agreements or easements. This includes, among other things, mandatory connection and usage requirements for local/district heating (for a certain period) or an efficiency level (I currently have a case for a client who must meet KfW 40 standards). This is legally sound.
As always, of course, workmanship errors are vulnerable to challenge...
In this case, there is no easement registered in the land register. Another obstacle, as far as I know, is that if there is an obligation to connect, the company must be publicly or municipally owned, not a private company... In other words, a public utility or something similar, but not the wood chip plant owned by Farmer Erwin.
I have one more question regarding which option is more economical or better. Which system has lower ongoing costs and provides better hot water quality?
Enerpipe high-performance storage tank HPDL combined with a fresh water station
or
Layered combination tank with stainless steel coil for legionella-free hot water production
The technical guidelines recommend a minimum volume of 600 liters (160 gallons).

We receive district heating from a large biogas plant, and I don't want anything else anymore. No hassle, no maintenance, and it can’t get any cheaper than 5 cents per kWh, plus if the transfer station breaks down, it’s not our problem.Did you get the storage tank from the company or just the transfer station? We should pay about 9 cents per kWh... plus a basic fee of €416.
No, storage and similar topics are our focus. The local heating network is cooperatively managed, and the transfer station is provided by the local heating system.
I believe the monthly advance payment is about 120 euros for the "basic fee," plus around 5 cents per kWh, which decreased from 7 cents to 5 last year.
As mentioned, maintenance costs are almost zero, except for what concerns us (hot water generation and heating).
