Looking at these US prices with envy. Heat pumps are just becoming a thing in Europe and currently installers are looking to earn a quick buck. I've not seen an install under 20k in the UK lately, bolting on to existing radiators. Also Europe seems to be heavily into air-to-water systems.
My wife paid 4000 euros for a heatpump in Finland, last year. Mostly to be used for cooling during the summer, rather than for heating in the winters (since there is "district heating" available for that).
Seemed pretty cheap, and the installation only took a day.
US (attempted) buyers of air-to-water look with envy to the Nordics, Northern EU, and the UK. My quote in the US was almost double that figure (for an installed system). The parts prices you’re looking at are indeed cheap. The labor is moderate. The profit margins are high.
where do you life? in germany they are available for years already. friends built new homes with them 5-6 years ago and back then it was already established
