It's -22C here this morning (-8f), and both of my heat pumps are working fine (currently 20.5C indoors). I have an LG, and a Fujitsu. The LG has an element inside the central air-handler as well, so if it gets too cold, you can switch that on to provide backup heat. I expected to need it last night, but the heat pump did fine without it.
