Checking the prices here in Norway a Mitsubishi Uwano 8700 (Mitsubishi's most high-end model) costs 2700 USD before any government rebates. It guaranteed to work down to -30C, but has been tested down to -36C as well. At -25C it produce 6000W. The "SCOP" value of the Mitsubishi is 5.2, so over the heating season it should produce 5.2x as much heat as you otherwise would get for the same amount of electricity.
Most of the heatpumps available are about 1200USD cheaper, but only go down to -25C, which really is plenty where most people live (not too far from the coast). Installation typically costs around 600-900USD it seems.
Given our 25% sales tax and high wages it should be considerably cheaper in the US.
- SketchySeaBeast 3y agoAh, that's a single room heater, not a whole house, eh?
- bjornasm 3y agoIt has a max capacity of 8700W, if that is just enough to heat a single room you have to look into insulating house better.
- SketchySeaBeast 3y agoWell, our whole house needs about 70,000 BTU, which is ~20,000 W or 10,000 W (assuming it's still 2x efficient) input at -35 C, but our basement and second floor won't care if the living room is the only area getting heat.
- mitthrowaway2 3y agoWhat makes you think it's a single room heater? It looks like a mini-split system to me.
