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.
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.
Hell yeah, we’ve got a heat pump and we’re in Canada where it can get to -40°C (which is coincidentally also -40°F) and that thing works like a beast. Fortunately we also have the cheapest electricity in North America so the decision was easy.
The Mitsubishi Hyper heat can work down to -13F,
The absolutely best resource I’ve found for heat pump research is the NEEP database which will you give you actual BTU outputs at various ambient temperature readings: https://ashp.neep.org/#!/product_list/

Also worth considering a geothermal heat pump depending on your geography, as then you have a guarantee of efficiency all year round
Second the NEEP database. I’d just add that the lowest temps listed here aren’t the actual equipment minimums - each model has a cutoff temp where it will literally shit the bed (except ground source of course). For my mistu hyper heat, it’s -26F. Capacity will keep dropping after -13F though (where it’s still at like 80% I think).
But that wouldn’t be accurate because there are South American countries with even cheaper electricity than here, so it’s only the cheapest in North America.
Also not to be too pedantic but central America isn’t technically a continent, and it all falls under North America anyways.

What’s your heat pump? I’ve been looking into them and I can’t find one that’s willing to say it works past about -15.

Can you just start saying “America” that way it includes south America and Central America, also?
