Is that the typical range in a normal year? Or is that the all-time extreme record? One thing people tend to do when they look at heat pumps is look at the typical extreme low for the year and size the heat pump based on that. But even if you touch -20 a few times a year, your heat pump doesn't need to be sized to heat in a constant -20. If you hit -20 once or twice per year then it's usually only for a few hours and the lowest that you really need to heat through is usually much closer to -10 or higher. But, yes, if you're in a climate that sees frequent and sustained temps of -40 then a heat pump probably isn't for you or the rest of the Canadian Prairies.
