Hello everyone,
I will be building a house in 2021/2022 and will live in it myself. It’s a 10x10 meter (33x33 feet), 1.5-story standard single-family house. The roof is a pitched roof with a 40-degree pitch, ridge direction North/South (so the roof faces East/West and can be equipped with photovoltaic panels).
Now, my question: Gas is available in the area. Which heating technology would you recommend?
Gas? Air-source heat pump + photovoltaic + battery storage? Ground-source heat pump? Or something completely different?
And who can give me advice like this without any hidden profit motives (like heating installers always pushing gas, etc.)?
Regards,
Flo

Insulation has the greatest impact on heating costs, followed by the design of the underfloor heating system, and finally the heat generator.

Oh yes, the consultant said his services would cost a total of €4,500, with half of that reimbursed by KfW – is that within the normal range?Wow. What exactly does that include? In my case, it was €1,300 (with €800 covered by BAfA/KfW). That included an on-site visit with an inventory assessment, advice on what would be most effective, and a room-by-room heating load calculation.

which insulation standard you aim for,42.5cm (17 inches) block – N8 or N9, depending on the price difference.P

The thickness of the masonry alone does not say much.
