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

Sorry my mistake.

The fluctuations in electricity prices are of course only marginal. Because it only knows one direction: upwards... and simply doubles on average every 20 years. This will not get any better in the future either, as demand will increase significantly due to current policies. It is, of course, different with gas. The gas price is relatively stable and is actually still too cheap. All figures on raw material prices are also freely available and verifiable from various sources.

kWh electricity 2000 = ~14c
kWh gas 2000 = ~4c

kWh electricity 2021 = ~32c
kWh gas 2021 = ~6.35c

I do not only see this in the abstract prices but in the direct comparison of several properties. Electricity bills have increased much more in recent years than gas bills with the same consumption, because nothing changes in the properties. They are used in the same way and have the same consumption values. Only the bills are higher. Despite regular switches, bonuses, etc.

Sure, ideally the heat pump produces 4kWh of heat from one kWh of electricity, which is great. But... but... but...

... but I'd rather save 100 euros and destroy the habitat for all future generations? Yeah...

Uhm no… please take off the [Aluhut] and stay factual.

Exactly my opinion. So, back to the text.

Edit: No, wait. I should stay factual.
So: do you have any scientist who supports your position "Gas is still kind of okay"?

Thanks to everyone for the comments so far! It is a hot topic, I know.

We will talk to the two neighbors to find out whether they would (potentially) be disturbed by an air-to-water heat pump or not.

The general contractor (or the commissioned heating engineer) only installs Vaillant. We are also getting the controlled residential ventilation from Vaillant. We have no key data yet like heating load calculation, etc., we would need to inquire or commission that.

If you ask the question, the train has already left ;)
