Hello forum members,

I am currently deciding between district heating or an air-to-water heat pump.
What do you think is the better/cheaper alternative?
Key data:

Distance from street to utility room approx. 40m.
Compact station without installation: 600 €
Connection costs for water/district heating/electricity: 2500 €
Cost of pipe for 40m district heating: 115€/m*40m =4600 €
Total for district heating without installation: 5200 €

GÜ credit if air-to-water heat pump is omitted approx. 8000 €

Is the extra cost for the air-to-water heat pump and the "independence" gained from the utility company worth it?

Regards
Steffen

What does a kWh of district heating cost? With an air-to-water heat pump, you are also dependent on the electricity provider.

Hi,

correct, but it can be switched if necessary.
It is about 9.2 ct/kWh

So I would keep it simple and probably use district heating. The underfloor heating will be planned the same way anyway? What supply temperature is it designed for? Even currently, with the air-to-water heat pump (properly set), you would probably be somewhat cheaper. However, if the underfloor heating is designed for low supply temperatures, it will be a breeze to have it installed later on. Regards Joe

In terms of investment costs, district heating is apparently ahead. However, you still need to calculate the consumption. How much does the kWh of electricity cost?

Guess about 20 cents/kWh. The question is how much heating energy you consume, with about 200 sqm of living space and Kfw 70 standard.
