Don't heat pumps stop working around -25C? That is obviously not going to be effective in alberta. (Current temp -36C [not including windchill])

The windchill actually only affects humans - moist skin cools down faster in the wind.

But -36 is enough to bring down heat pump efficiency a lot.

This site [1] talks about heat pumps that work down to -30. Not good enough to trust your life to if you’re an Albertan.

I believe the heat pumps intended for these climates provided alternatives for those cold days. If you want to stay all electric, it would include a resistive electric heater, but could be paired with some other fuel source.

Personally, I'd seriously consider going ground source where temperatures like this are the norm, but that doesn't work for everyone either.

That may work for your house, but it really doesn't make sense for the emergency heat source of your vehicle to also need an emergency heat source.
