RoomHeatPumps
Heatpumpsworkbymovingheatinsteadofcreatingit. Inthe
summer, the cool indoor coil absorbs heat from your room
andmovesitoutdoors,providingcooling. Inthewinter,heat
pumpsreversethisoperation. Byloweringthetemperature
of the outdoor coil below the outdoor temperature, the heat
pump absorbs the heat from outdoors and moves it inside
yourhouse. This heat transferringprocessisveryefficient.
Forexample,at45°Foutdoortemperature,aheatpumpcan
provide 2 ½ watts of heat for every watt of electricity it
consumes.
As outdoor temperatures drop, the heating capacity and
efficiencyoftheheatpumpdeclines. Attemperaturesbelow
45°F, it is likely that ice will form on the outdoor coil. Heat
pump units are designed to operate as a heat pump above
approximately 40°F. Below 40°F, these units switch auto-
matically from reverse cycle heat pump to auxiliary electric
heating. No defrost is required. There is no minimum
operatingtemperature.
