You have to have a gas backup in cold climates. You can't just dump NG. -22F is the limit for useful heat production from a heat pump.

- boplicity 3y agoGround source heat pumps, frankly, should be mandated in cold climates. That completely removes any cold-air limitations. That being said, backup power is still vital in extreme climates.
