Why do ASHPs save more energy than traditional heating and cooling systems?
When properly installed, an ASHP can deliver 1½–3 times more heat energy to a home than electric energy it consumes, so for every unit of energy you put in, you get 2 to 3 units in return. As a result, these systems can provide heat for Minnesota’s shoulder seasons (fall and spring) at a higher efficiency and lower cost than electric resistance heating, oil, and propane heating, and in some cases, for a lower cost than gas heating as well.
