A heat pump system is provided. The system includes a closed loop for refrigerant flow, including an evaporator, an expansion valve, a compressor, a heat pump heater that comprises a first condenser, and a second condenser wherein refrigerant flows continuous through loop and through the components continuously, and a flow of forced air across the heat pump heart and the evaporator. The expansion valve is remotely controllable in order to adjust a refrigerant pressure drop that occurs as refrigerant passes through the first expansion valve. During operation refrigerant may cause moisture to freeze upon the outer heat transfer surface. Periodically the first expansion valve is adjusted to decrease a pressure drop of refrigerant that flows through the first expansion valve thereby transferring heat through the evaporator and to the outer heat transfer surface to cause the frozen layer upon the outer surface of the evaporator to melt.
