The colder it gets, the lower the efficiency. In a more extreme climate like Fairbanks, the efficiency pretty much drops down to resistive heating (1.0).

If you're set on electrifying there, it might make more sense to investigate a ground-source heat pump which leverages the ambient underground temperature for heat exchange.

Big plus to ground-source here! Everything shown on the site today is air-source only.
