Heat pumps can't take the cold? Nordics debunk the myth::By installing a heat pump in his house in the hills of Oslo, Oyvind Solstad killed three birds with one stone, improving his comfort, finances and climate footprint.

Good Lord - $2600 for a whole house system? I think that's what my local (mid-Atlantic US) HVAC shop is getting for a single-room mini-split.

Wait until people find out about ground-source heat pumps and water heater heat pumps. What you get out of those is more consistent year round, too. It's almost like leveraging technology has benefits over just burning carbon and hydrogen to make heat.

Yeah, no. German here, if your house already is all prepared, ideally with large radiators or heated floors and you really just have to switch out the source of heat from whatever to a heatpump, then you're maybe looking at 15k€ including work. The man probably collected a properly dimensioned subsidy.

You're just repeating what all the gas installers keeep repeating so they don't lose business.
Every House built after 1990 or houses that have had insulation makovers in the past 20 years are perfectly fine to heat with a heatpump.

Yeah, I know, I have a heatpump. However, it's just working so well at about a COP 1:4 at the moment because I've got flow temperatures of less than 30°C due to heated floors. If I needed 50°C I'd be down to about 1:2.5 right now and that's not cost saving anymore compared to gas.

And I've checked, my exact model costs about 13k€ right now, make that 2k€ installation costs and we're not far off.
