Hello everyone,
Our building contract includes gas with hot water heating and underfloor heating.
For an additional 12,000€ (approximately 13,000 USD) we would get an air-to-water heat pump. From our perspective, that’s too expensive, right?
The idea was to have gas installed first, then sell the gas boiler later and install the heat pump afterward (by outsourcing the work separately).
Is it that simple to swap, or is our idea missing something?

I would have preferred gas – it would have cost an additional 4,000 (since solar would also have to be combined (KFW55))Nowadays, gas without a solar component is no longer possible. It is a minimum requirement of the energy saving regulation.

We even build KfW55 standard homes with gas and without solar, but with a good building envelope.

Caspar202010 May 2017 12:36So you’re saying you’re building a KfW55 standard house using only gas, without solar thermal support and without controlled mechanical ventilation, with a building permit/planning permission issued after 01.01.2016.
Achieving a primary energy (PE) value under 51 is already quite challenging. But getting below 35 for the PE value ops:
What kind of building envelope is that?

Sascha_aus_H10 May 2017 12:59No, we of course have a mechanical ventilation system with heat recovery; otherwise, in my opinion, that would definitely not be possible.
We were able to eliminate the solar heating system we did not want only by slightly improving the building envelope.
