Gas with solar thermal? Or heat pump with photovoltaics? Consultation

I am not arguing at all, I am just repeating.

You, on the other hand, argue,

with your crystal ball.

current political will

Amid all the speculation, the fact is that I can operate partially self-sufficiently with photovoltaics

Alright, then I just consider the argumentation you present to be doubtful.

I don't argue any more than that, but rather present contexts and facts.

With what else should I predict future developments? You obviously have a more valid tool at hand.

If only politics knew what it wanted. Nuclear phase-out yes. No, actually not. Yes! A CO2 price must come. A little bit. More!
This haggling about the Renewable Energy Act going away, replaced by CO2 pricing is nothing other than a compromise between Red-Green and Black interests. One side wants a price for CO2, the others want the Renewable Energy Act surcharge removed. That’s the deal ("political will"). It was NEVER about price reductions for electricity; that could be regulated much more easily with corresponding tax cuts. It’s about balancing interests, ideally if you can still package that nicely for the electorate.

You want to trigger me, don’t you? Autarkic is someone who has no grid connection. If even 1 kWh passes through your meter (no matter in which direction) you are certainly not autarkic. Neither fully nor partially.

Can you describe how you implemented it, which heat pump, the setup of the cooling so that one could possibly do it themselves as well.

probably he has a reversed heat pump, i.e. air conditioning

For testing the cooling function via the underfloor heating, a Rotex HPSU was used back then. Now it’s a Daikin Altherma’s turn (the Daikin basically represents the same unit). This one cools the air directly and no longer the underfloor heating. Yes, colloquially this is called an “air conditioner” but technically it is and remains a heat pump.

No, the controlled residential ventilation has nothing to do with this; it does not provide the required air volumes to achieve effective cooling. But it of course remains on despite the cooling operation.

Otherwise, yes, heating with gas via underfloor heating... cooling with air-to-air heat pump. In my case, the most affordable solution. Although the cooling is optional, I still recommend it to everyone (in addition to the shading concept) since summers are getting warmer, but everyone has to decide for themselves.
