Operate heat pump autonomously with photovoltaic system.

In the end, the question in X years will be: How much do I have to pay monthly for heating energy.

It doesn't matter if it's 100 euros for electricity or 100 euros for gas, wood, whatever.

Exactly. Better to build as efficiently as possible with a photovoltaic system and live off your own electricity. That is then significantly cheaper than 100€ per month

I have not read the entire thread, but operating a heat pump solely with photovoltaic (autonomous) will be quite experimental, or collector, buffer, and heat pump must be very generously sized for the winter so that it even remotely works properly. And then we are far from economic viability.

Not necessarily autonomous. Depending on the budget. But on average €240 electricity costs per year is better than €200 in two months.

And what does this system cost monthly? How about taxes?

In the end, it doesn't get cheaper, but it also doesn't get more expensive. That is (without storage) initially just a matter of right pocket, left pocket.... And after 10-14 years we can then talk about "worth it."

But it definitely is worth it. Many forget some factors, like rising electricity costs, etc. I have dealt extensively with the storage systems available on the market and calculated all costs up and down. I will work on that soon and gladly post the link here. It is more worthwhile now than ever...

Then you get started...

I predict that the electricity costs with storage (all in) will currently be around 35-40 cents.

As long as these prices are not permanently undercut by grid electricity, you will pay for it.
