There are three types of heat pump systems typically used in homes today: All-Electric Air Source, Dual Fuel Air Source; and Ground Source Heat Pumps, also called Geothermal Heat Pumps (GHP). All-Electric Air Source units use electric resistance coils to provide supplemental back-up heat. Dual-Fuel systems pair a heat pump with a gas or propane furnace which provides back-up heating when outdoor temperatures drop to approximately 30°F, or lower. GHP systems differ in that they utilize the earth and its constant 60-65°F subsurface temperatures as the source for heating and cooling.
