Ranked by winter-long heating efficiency only

Heating efficiency over a whole winter, measured with a federal test. Like miles per gallon for heating: higher means more heat per unit of electricity over the test season. The federal minimum for a new split heat pump is 7.5. This list ranks by that one rating. For the units that hold up best in the cold overall, see the cold-climate picks.
