I’m having a cheap Gree Flexx installed at the moment, and even it can heat down to -22F (-30C). People use them in Canada without heat strips.
I’m in the San Francisco Bay Area so it doesn’t get too hot nor too cold here. Very rarely goes above 86F (30C) or below 41F (5C). Good weather for a heat pump. We did actually use the old furnace last winter - it got colder than usual.
I’ve got 11.2kW of solar panels too, so electricity is much cheaper than gas for me :)
Sure lots of heat pumps can “heat” that low, you’re not getting very much heat though. I’d be surprised if they don’t have some kind of supplemental heat source. I didn’t see any actual engineering documents to see what the outputs are at those ranges. To heat a space you should have output temps minimally in the low 90F range. Some of the heat pumps now are heating the refrigerant seperately in those low temp conditions. So kind of cheating.
