Renew old heating with heat pump or gas boiler and domestic hot water heat pump

He just doesn’t want to install a heat pump because he has been installing gas systems for 30 years. Sure, during the transition period, which accounts for about 10% of the annual heating energy, you can heat with the heat pump. Still, in winter you waste a lot of gas AND can only use a very small portion of the energy produced on the roof that might still be generated. Such a solution is a good idea in an old building if you currently don’t have the money for a complete heating system renewal. And of course, it’s better than nothing.

In the end, you have to pay and decide for yourself. But all acquaintances who installed a heating system in the past 10 years that wasn’t a heat pump are now complaining nonstop that it was unfortunately the wrong decision. Therefore, I can’t understand how anyone can even consider it and am probably no big help because of that. I might still understand if someone lets the old system run a bit longer. Replacing it again with a technology that should have been banned 10 years ago (and isn’t only thanks to intensive lobbying and consistently corrupt politicians) I consider a huge mistake.

Hm. How much is the price increase? Bafa currently needs at least about two months. Back then I guessed and just started building. But I would have had to replace the heating anyway...

Theoretically, the risk certainly exists. In my opinion, however, only if you have either provided false information or simply are not eligible for funding (house too new, heating system too new/old, address not in Germany...). I have not heard or read of any case. But that doesn’t have to mean anything.
