House planning final: heating components, what makes sense - no air heat pump

Yup. For the expansion to 3.3 kWp, battery and inverter.

If you want to do without fossil fuels such as oil and gas and are already aiming for KfW 40 insulation-wise, are there any other options besides the exhaust air heat pump that definitely need to be considered?

Air-water heat pump (Air-water heat pump) or brine-water heat pump (brine-water heat pump)

Yep. For the expansion to 3.3 kWp, battery and inverter.

Tesla?

Yes exactly, it is a Tesla home battery in combination with a SunPower photovoltaic system.

So I probably guessed correctly regarding your current favorite.

You can find a lot of information about the Nibe on the net; especially from builders of your potential building partner.

A fireplace is "not worth it," it is something for personal well-being; although there are already smaller fireplaces around 3 kW. Procuring wood, cleaning repeatedly, a decision that no one can take away from you. Save heating costs because of it? No, unless you get the wood for free.

Thinking about "other" alternatives for heat generation is unnecessary if you want to sign with the provider; of course only if I guessed correctly.

A Nibe 750 was also presented to us as a favorite by the house building company. However, we could not warm up to the idea of an exhaust air heat pump.

We have now decided on a Stiebel Eltron LWZ 504 (= air-water heat pump + controlled residential ventilation). (House 140sqm, insulation KFW40)
