Ranked by heat output at 5°f only
How much heat the unit can deliver when it is 5°F outside, in Btu per hour. Useful for comparing units. Whether it is enough for a particular house takes a load calculation. This list ranks by that one rating. For the units that hold up best in the cold overall, see the cold-climate picks.
