I should also acknowledge that at least one member who switched from gas furnace to heat pump was unpleasantly surprised at how much electricity that the system used. I have to say that part of the reason why I'm interested in a dual fuel system is as a hedge in case the heat pump uses far more electricity than expected. A second reason is in the case of power failure the gas furnace and blower can be run off of backup power, while the heat pump likely draws too much current for that. And of course heating while outside temperatures are below freezing is a third reason (unless I decide to spring for one of the new cold climate units).
