If you actually live in an area where temperatures drop below -30C regularly, you might want to consider a ground source heat pump. They are a bit more expensive than the typical air source heat pumps since there's some digging involved, but for a new house they aren't that much more expensive since there's already digging for electricity, plumbing, etc. For example ground source heat pumps are getting quite popular in Finland.
- xienze 4y agoWho’s talking about -30C? I’m talking about 32F, or 0C. I’ve yet to be impressed by a heat pump once the temperature gets at or especially below freezing. Geothermal heat pumps are great but at least in the US they are wildly expensive compared to traditional ones. You either need a large lot for horizontal laying of the pipe or a DEEP hole if going vertical ($$$). Plus they’re uncommon enough that contractors are happy to charge a serious premium.
