Less money over 10 or 20 years sure. Short term you're paying way more.

If I had 20k EUR to spend, I'd get a heat pump too. Unfortunately I’m stuck with my 40 year old furnace that’s completely manual. If I were to replace the whole thing with an automatic modern one that burns pellets, it’d be under 10k, and a regular one maybe 5k.

I do have an air source heat pump but that is more of a supplemental heater and summertime cooler. I'd need 5 of these to heat the whole house and my electric bill would far exceed what I spend on briquettes for the winter.
