Lennox Landmark KHB074S4T
Air-source heat pumps (ASHPs) are all-electric building heating and cooling solutions that use electrical energy to move (not convert) thermal energy from a source to a sink, where the source is the outdoors in the winter and indoors in the summer. An ASHP thus pumps heat in the opposite direction from which it would normally move.
