Hello, I want to build in the near future and cannot decide between gas and geothermal energy. The single-family house with Kfw 70 (basement, ground floor, 1st floor and attic conversion) has 163 sqm of living space and 2 people live in it. Underfloor heating is also planned. How can I heat hot water and heating most cheaply? What is the most cost-effective and why?
Best regards
