Describe the operation of a dual fuel heat pump operating below the balance point
What will be an ideal response?
In a dual fuel system, the furnace operates below the balance point and the heat pump shuts off. When a gas or oil furnace is used for supplemental heat, the heat pump shuts off when the furnace comes on because the hot air from the furnace passing over the indoor coil would cause extremely high head pressures in the heat pump.
