ᐅ District heating or another heating technology?

Hello everyone,

We are currently planning to build a KFW55 house in Bavaria.

The heated living area (underfloor heating) would be 160 sqm (1,722 sq ft). In addition, there is an unheated basement.
At the planned building site, there is a private district heating provider offering a 10-year contract. The connection and transfer station would be supplied by the district heat producer. The cost per kWh of heat is 8.33 cents. I actually find this solution very attractive, but you often read a lot of negative things about district heating.

The contract includes an economic clause. This concerns me because it means I would be tied to the contract for 10 years in case of possible price increases. What are your experiences with such district heating contracts?
Other heating options (possible are heat pumps and pellet heating; I do not want oil or gas boilers, and there is no gas connection available) do offer a lower kWh price, but they require high initial investments. I estimate these initial costs to be in the range of 15,000 - 25,000 € (16,000 - 27,000 USD). Are these amounts roughly correct, or do you have better estimates?

Greetings from Bavaria!

An annual consumption of 13,500 kWh would mean additional costs of about 400 €.

Especially since with a KfW 55 standard and 160 m² (1,722 sq ft) of heated space, the consumption is more likely around 7,000 kWh.

Does the contract state how much they are allowed to increase the prices? If the rate goes from 8.33 cents to 15 cents next year, that would definitely be a problem...

I would pay close attention to that as well. Most likely, the price is linked to some kind of index.

However, I believe there must also be consumers who have no issues with the rising prices.

In some streets here, people pay absolutely nothing for district heating consumption. These are contracts from the early days, when district heating was still considered the future and they only needed "a few" customers initially to make the whole system profitable and thus appealing. This often makes local news in winter because the supplier no longer finds those contracts very favorable.
