Alex, we simply disagree here. I wish you a functioning, durable heat pump. And I hope you wish me a functioning, durable gas boiler. Ideally, it lasts 25 years, after which I’ll be in the cemetery anyway. Karsten

I am really unsure by now. I have learned through various research that a new building with only a gas heating system no longer works. In other words, without solar, one probably does not meet the requirements.

As I said, we are building solidly with 36.5 t10 bricks, insulated ceiling and floor slab. No underfloor heating.

Still, I am unsure... should I bring in an external energy consultant?

Yes, you need a renewable share. Solar thermal energy, controlled residential ventilation with heat recovery, biogas from the farmer around the corner, ...

With radiators, a heat pump is virtually impossible anyway. In any case, it becomes almost unaffordable to maintain.

Only controlled residential ventilation or solar for water heating fits with the gas heating with radiators. The latter is cheaper. The former is comfortable.
