ᐅ New Single-Family Home Construction – Gas or Air Source Heat Pump + Photovoltaic System + Energy Storage?

Hello everyone,
I will be building a house in 2021/2022 and will live in it myself. It’s a 10x10 meter (33x33 feet), 1.5-story standard single-family house. The roof is a pitched roof with a 40-degree pitch, ridge direction North/South (so the roof faces East/West and can be equipped with photovoltaic panels).
Now, my question: Gas is available in the area. Which heating technology would you recommend?
Gas? Air-source heat pump + photovoltaic + battery storage? Ground-source heat pump? Or something completely different?
And who can give me advice like this without any hidden profit motives (like heating installers always pushing gas, etc.)?
Regards,
Flo

If everyone were to switch to electric vehicles and heat pumps in the next few years, including all new buildings, the power would go out by November at the latest, or coal-fired power plants would have to be used to meet demand.
In that case, no so-called green heat pump electricity tariff would help. The CO2 emissions would still occur.
So let's see where the energy transition stands in 15 years. That will be crucial.

I’m not an expert. But isn’t it actually the case that we already generate so much electricity from renewable energy that we have to sell it, simply because our grid can't handle the fluctuations?
If that’s true, then the demand shouldn’t be the problem, but the grid, right?

markus27039 Sep 2021 18:27On a July day, the demand is certainly not a problem – but at 5:00 PM in the gray November, it probably is. Where is the electricity supposed to be generated, especially in the windless southern regions?
Grid? From wind turbines in the north?
Hydropower plants?
And (I admit it) nuclear power? I think it was Belgium where they are about to connect the first plant that processes the waste generated?
Edit: The keywords transmutation and particle accelerators lead to what was mentioned.

A very interesting discussion.
For my new build (moved in at the end of 2018), I deliberately chose a gas heating system.What exactly led you to make this very conscious decision?Heiko123 schrieb:
However, environmental protection cannot always be carried solely on the shoulders of the middle class.Hmm, didn’t we already conclude a few pages earlier that it is not actually more expensive?!But since you made a deliberate choice, could you please share the costs for each option in your case?

Edit: the keywords and transmutation as well as particle accelerators lead to the mentioned topic. From wind turbines in the north? We can all see how slowly the expansion of the grid is progressing. And let’s be honest, Germany will never be able to meet its entire energy demand from the North Sea alone. Due to geographical circumstances, we will have to rely on fossil energy sources for a long time to come.
And nuclear power? Is that an alternative? Back to the 1960s... I live near a still operational nuclear power plant. Since 2011, this has been a real concern, and I will be relieved when the cloud in the sky disappears by the end of the year.
