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.

Do you also have an overview of the cooperative share and receive a refund at the end of the year?

How long is your price fixed?
What size and according to which standard are you building?
Do you have a heating load calculation and consumption estimate?

Hello,
I’d like to quickly share my experience here.
I am currently building and have the opportunity to connect to our village’s district heating system.
The costs involved are as follows:
- 4600 euros cooperative share
- 4800 euros transfer station
- 60 euros monthly fixed fee
- 0.07 euros per kWh consumption
A monthly advance payment of 150 euros is planned.

At these prices, I don’t have to think long about whether a heat pump will ever pay off.


We attended the cooperative meeting last week, and honestly, anyone who doesn’t join is missing out.
We pay an annual fee of 250 euros and 0.54 cents plus tax per kWh, plus a connection fee of 13,000 euros.

The project started 5 years ago and now, with 88 participants, the balance is almost zero euros, even with a slight surplus.

Heating cheaper than this is hardly possible, apart from the fact that the electricity consumption of the transfer station and two pumps is practically negligible.

They are now considering raising the connection fee from 13,000 to 17,000 euros for new connections, simply due to increased costs, but even that is a bargain compared to a heating system.

Maintenance costs are zero euros.

Heat pumps are much more complex and should be checked regularly; otherwise, they can become real electricity guzzlers.

Our neighbors installed a pellet heating system. It’s not like they weren’t asked if they wanted to connect, but if you don’t want to, that’s just how it is.

12 times 60€ is definitely much more than 250€.

It’s different if you are a member yourself compared to a company that is solely focused on making a profit... for you, it’s enough if you just break even in the end...

With 416€ base fee + 8.93 cents/kWh, it’s far from cheap either...

But for the cooperative share, do you also have access and get something back at the end of the year?

How long is your price fixed?
How big is your house and to which standard is it built?

Yes, you have access during the annual meeting.
Unfortunately, there is no return yet because investments are still being made every year, and the system has only been in operation for 11 years. For example, a large photovoltaic system was installed on the roof a few years ago. This year, the entire property was fenced.
The consumption price is definitely fixed for the next two years.
My house is 144 sqm (1,550 sq ft) and built to the KFW 55 standard, with an additional controlled residential ventilation system.
The energy consultant estimated a consumption of about 13,000 kWh without accounting for ventilation losses. I expect to be well below that, but I will only know for sure in a year. The move-in is planned for January/February 2023.
