Yep. We heat our house through Colorado winters (pretty cold, but not really cold) with just a high efficiency heat pump and resistive backup in the air handler

Yep. We heat our house through Colorado winters (pretty cold, but not really cold) with just a high efficiency heat pump and resistive backup in the air handler. The resistive is rarely needed. This is beside the point though which was that even non-electric heating systems often require electricity to function.
