Hello everyone,

I would appreciate your assessment regarding the district heating connection (mandatory in the new development area). I’m having some difficulty evaluating it. The plan is a KfW 40 house with a south-facing orientation (150 m² (1,615 sq ft)).

Question 1: The connection fee includes a buffer tank from Enerpipe, model HP1000ZL. A 1000-liter (264-gallon) tank seems quite large to me – currently, there are only 2 of us living in the house. How much capacity do we actually need here?

Question 2: The ongoing costs (all including VAT) are:
€30 (about $32) monthly basic fee
plus 4.5 cents/kWh
The minimum consumption requirement is 10,000 kWh per year, which means the monthly cost is at least €67.50 (about $72), adding up to €810 (about $865) annually.

The minimum consumption seems very high to me – what are your energy costs per square meter in a KfW 40 house? How can I compare all this in a meaningful way? Currently, we pay about €70 (about $75) in our KfW 70 semi-detached house with around 120 m² (1,292 sq ft).

Thank you very much for your comments.

The development plan does not mention any "mandatory acceptance."

"As part of the infrastructure development, the building area will be connected to the district heating network to be established by Nahwärme XX AG. The connection of each building plot to the district heating network is mandatory."

Where are the legal experts? Basically, this only means that the property must be connected, but it does not say that I have to accept their services, right? 😉

I think it’s great that the district heating in the villages is 100% green energy. All good. I would accept that too – but strictly based on consumption without a minimum purchase requirement. I don’t mind paying €67.50 (about $70) per month for heating and hot water. What do people pay for their KfW55/40 houses? Surely it’s not as little as €30 (about $31), right?

When the number of customers decreases, the fees increase. Once the connection is established, you at least pay the basic fee.

An acquaintance now pays 160 for the basic fee and 40 for consumption, since there are fewer customers than planned. They are ready to sell after one year.

Well, eventually the operator might go bankrupt, and then you’re out again, right?

Is there a thread here where everyone shares their consumption data?

Is your system up and running now?
What is the capacity of your storage system?
