Newly built single-family house - gas or air heat pump + photovoltaics + storage?

No, wait. I'll address that directly.

with such provocative statements, hopefully you haven't built a single-family house, don't have a combustion engine vehicle, don't fly, and don't have children...

Except flying, yes. With a heat pump.

Let's not exaggerate.

Reluctantly. Keyword "ideology."

Gas is also a legitimate way to heat nowadays. Electricity is also getting more expensive.

What exactly do you want to say? You'd rather save (which is hard) 10 euros a month, while everyone else has to suffer? Sounds harsh – maybe provocative. But in the end, that's exactly what it is.

Choose the "sweet spot" between cost and ideology.

Climate IS NOT an ideology. That is consensus. Which brings us back to the beginning of my "provocative" statements.

Why does the state probably promote heat pump technology ...

Because it really can't be done any other way anymore. They tried. ;-)

Because it really can’t be done any other way. They tried. ;-)

Honestly, I don’t believe that.
Why? Because only people who already have enough money benefit from the subsidies.
Do you think a family that has to live on €4000 gross is interested in heat pumps?
Let alone an individual who, with luck, earns €2000 net?
They probably don’t even know what that is. And if they do, they probably don’t care, because unlike us in this forum, they simply have to figure out how to make ends meet.
I wrote it in another thread:
1st World Problems.

I agree with you when you say something needs to change. Also in people’s minds.
At the moment, however, only the privileged can do that.

We are here in the "hausbau-forum". It is about new buildings. I never said that the unemployed person is an idiot if they heat their rental apartment with gas.

Regarding the other points: With electric cars, it was also those who could afford very expensive cars at the beginning. And now electric cars are the cheaper alternative for many when you do a full cost calculation. And soon, only the well-off will be able to afford classic cars.
Another example: photovoltaic systems. 20 years ago, you needed a lot of money, a subsidy, and patience (until the money was back). That’s how the technology was developed to the point where it is now practically unbeatable in terms of cost. That was good too, wasn’t it?

Why does the state promote heat pump technology and here only particularly efficient ones?

I understand what you want to say with that. But I do not necessarily deduce existing ecological awareness of the decision-makers solely from the fact of a subsidy or a political decision; this topic has been known for decades and yet they have promoted poison-spewing technologies from coal to combustion engines. When I recently saw the promotional video of the Minister of Agriculture together with Nestlé or, for example, the renewed postponement of piglet castration, etc., how should I as an ordinary citizen then find the belief that decisions in the residential construction sector are made solely for climate protection reasons? If that were the case, we would have, among other things, had a speed limit long ago.
If politics had truly understood the climate problem, it would have had enough opportunities across parties in recent decades to steer the wheel in a different direction; even Mr. Kretschmann does not get under the 500-series Mercedes, he did not even want to discuss it.

If gas is such an extreme killer, I would be in favor of completely banning its installation; then that’s just how it is because it is harmful to the climate!
But to even promote it indirectly through KfW, to build new pipelines, but at the same time to outlaw it, that doesn’t quite make sense to me.

When these questions have been answered, one should know what is currently societal consensus through the society via the elected representatives and thus a majority of the population.

Why is the possible gas heating outside the current societal consensus when the above-mentioned elected representatives precisely allow this gas heating as part of the KfW subsidy?

What I still have to get off my chest because I simply find it perverse. When I look at which "electric cars" are driving around here with us (and there are quite a few now because of Telekom, Post/DHL, Postbank/Deutsche Bank, United Nations, Bechtle, and others), it makes me sick. These are all big rigs, hybrids that have a tiny electric motor and a big combustion engine. Thick SUVs, luxurious limousines. They then think they are the game changers because they drive luxury cars subsidized by the state and provided by the employer, which can barely store enough electricity to get to the next [alnatura]. Double standards to the very end.
