Construction costs are currently skyrocketing

I strongly doubt that you can reach 65% with solar thermal. Even with optimistic calculations, it simply doesn't add up

That never works, I want to see the calculation ...

So far, that was the trick to include a renewable share in gas heating systems. Whether it still works with 55/65% will be checked by the manufacturers and possibly implemented in products. I also can’t imagine it. In any case, the solar thermal system would have to be integrated into the heating system; so far, it was sufficient to only support domestic hot water heating. As I said, it was all just label fraud, but it was enough to comply with the laws. People will get creative again. First, the law needs to be in place so that manufacturers can put together their product (packages) in a solution-oriented way. It is by no means the case that the draft entails a “heat pump obligation” or something like that, even if WELT likes to label it like that for their target audience. Simply a lie. I want to emphasize again the split air conditioning variant. Great annual performance factor, relatively easy to retrofit without a “complete renovation,” and lastly subsidized in existing buildings with 30 or 35% through BAFA. Plus the comfort in summer.

I suspect that the 65% figure is more likely achieved with something like a hybrid heat pump (? don’t kill me if the name is wrong), so basically mostly heat pump and something extra to heat during the coldest winter? But that also sounds like an expensive affair.

The scenario "someone bought a house with a 28-year-old heating system during the low-interest phase, financed it to the limit, and now can’t afford the new heating system" honestly sounds very contrived to me. If I buy a house with a 28-year-old heating system, I fully expect that I will have to deal with it soon. And these ideas don’t come out of the blue either. That means either I make sure to renew the heating system quickly now without changing the technology, or I spend more money and switch to something else now. It’s always portrayed as if "completely insulating everything, installing underfloor heating (does the statics even allow that), then you can go for a heat pump" is the only option. If there simply isn’t any money for renovation measures, one is presumably more likely to go for pellets or something (edit: or the above-mentioned split AC). Otherwise, there are quite a few intermediate solutions between "renovate your house completely for 200k and run the heat pump at 30° flow temperature" and "completely unrenovated, annual performance factor <2."

Let's wait and see... I don't believe in a second term where the Greens have a say... Maybe the problem will resolve itself even sooner

I personally didn't vote Green back then, but I think they are doing the best job so far.
This agitation is simply ridiculous and 0.0 solution-oriented.

I don't find the best job or maybe I do because the rest is terrible?
You surprised me positively - just a year ago.
