"The
U-Crown heatpump is specifically designed for Canadian weather with its 2-Stage compressor. It will keep you warm during those harsh winters with a capacity to run at full efficiency up to
-30ºC outdoor temperature."
So, -22 F seems very close to the US Crown series at -20 F..
Maybe I need to find some reviews who live in the US snow belt..

Edit:
Tested the Reactor this afternoon. That dead-short on the VOM was bugging me.
It has pretty good Reactance. Not shorted..
It reacted much like the big 60hz transformer I tested the rig on, before dragging the function generator out there..
Not as high as the transformer, but close enough to say it's good.
