Like fast cars, each year brings improvements.
My heat pump is rated for minus 13F, and we had three days of -13 at Christmas my heat worked OK and does NOT have any electric resistance heaters.

A middle-of-the-road model.
I installed a separate electric meter to record the usage.
22 Dec 20.05 KWh,
23 Dec 29.02 KWh,
24 Dec 21.5 KWh
