Good morning,
I’m new to this forum and trying to work my way through the topics as best as I can.
My family and I want to build a single-family house – 150 sqm (1,615 sq ft), located in North Rhine-Westphalia, a new development area, for a total of 3 people (2 adults, 1 child).
The development requires the use of a cold local heating network, meaning you pay a fixed price regardless of how much you actually use.
This would come with a brine-to-water heat pump, including maintenance and so on. However, you’re tied to the energy supplier in terms of the heat price – the system is not allowed to be powered by a photovoltaic system. Estimated monthly heating costs from the supplier are about EUR 115 (USD 115) per month, including cooling.
What do you think about this? Should we accept the offer, or rather go with an air-to-water heat pump from the house builder, who says their system can cover heating for “60 EUR (USD 60) per month”?
I’m very skeptical but don’t have the technical knowledge to make a proper assessment.
Looking forward to your feedback.

Estimated monthly costs from the utility provider are EUR 115 per month for heating (including cooling). Since this estimate comes from the utility provider, I would be a bit cautious. What exactly is the cost per kWh of heat? How high are the fixed fees? What factors will influence future price developments? Does the utility provider supply the brine-to-water heat pump for installation in your house? To my understanding, this is also needed for low-temperature heat.

Haven't you asked that before? Possibly under a different name and thread? In my opinion, the restriction was the same. If not, try searching for your buzzwords here.No, I'm completely new here 🙂 but maybe someone is building near me or in the same neighborhood.. I'll take a look right away to see if I can find anything ..bauenmitschaf schrieb:

From my understanding, this is also required for low-temperature geothermal systems. Yes. The pump is provided, all costs are disclosed… I need to look them up… I only noted the value including cooling…
