Which heating system is currently the best?

Nice when all you energy savers primarily think about operating costs.

Just to be safe: I definitely don't belong to that species.
For me, electricity comes from the socket and the house has to be warm
How it works and what it costs is actually relatively irrelevant to me...

It can't hurt to broaden your horizons, can it? I can only recommend it to you. It's good for general knowledge...

How it works and what it costs is actually relatively unimportant to me...

Well, then I wonder what you are doing here in this thread?

This is about finding a good price-performance ratio when choosing the heating system. Affordable, economical, and future-oriented.
At least, that's how I understood the initial questions...

Why do you write everything twice?

I get electricity from the socket and the cabin has to be warm
How it works and what it costs is actually pretty irrelevant to me...

Sarcasm on:
"... so having your own nuclear power plant in your garden would also be an option for you ..!"
... I’m already gone ..

Wouldn't be a bad idea either. If only it didn't take up so much space.
