Claim:
1. A method for operating a heat pump system at low ambient temperatures of about 5° C. or less comprising the steps of: operating the heat pump system to transfer energy from an environmental medium to a refrigerant and subsequently transfer energy from said refrigerant to a fluid; maintaining a temperature differential between said environmental medium when said environmental medium contacts an evaporator coil of said heat pump system and said refrigerant when said refrigerant is located in said evaporator coil of about 5° C. or more by heating said environmental medium using a heater prior to the environmental medium contacting the evaporator coil when a temperature of said environmental medium is less than about 5° C. above a temperature of said refrigerant; and inducing a plasma discharge in said fluid sufficient for producing shock waves that cause precipitation of mineral ions from said fluid and generating an electric field in said fluid.
