heat pump uses electricity to run a compressor to compress a non-CFC refrigerant gas. These gases put up to 6 times as much heat in to the water compared to the electricity consumed.A heat pump not only saves you money it greatly reduces your carbon emissions. ECONOMY THE HEAT EXCHANGER Threaded coaxial coil heat exchanger (outer tube stainless steel, inner tube copper threaded type). THE COMPRESSOR The Enersave comes with a scroll compressor offering the Smoothest,Quietest, Most Efficient Compressor Technology using advanced engineering and flow dynamics to more efficiently and smoothly compressgas refrigerant. SOLUTIONS FORfor MAJOR ENVIRONMENTAL CONCERNS HOT GAS DEFROST -THE SOLUTION FOR LOW TEMPERATURES defrost system enables usage at much lower temperatures than a regular heat pump. When the evaporator starts freezing, hot gas is sent to the evaporator, thus bringing back the unit full efficiency in seconds. CHARACTERISTICS AND BENEFITS THERMOSTATIC VALVE: Protects the compressor and ensures the right quantity of coolant is provided to the evaporator for maximum energy efficiency. FAN BLADES: Designed to reduce noise level to a minimum. NOISE INSULATION COVER:Covers 100% of the compressor to reduce the noise level and protection. ELECTRONIC DIGITAL DISPLAY WITH SELF DIAGNOSTIC SYSTEM: Easy to operate digital display with self identification of problems and security shut down. OVERSIZED EVAPORATOR: Ensures a greater level of efficiency and longevity, reduces noise and lowers the operating pressure. DEFROST CONTROL : Automatic defrost system. DEHYDRATOR FILTER: Protects against condensation and humidity and other harmful particles. ULTRA RESISTANT RTM LIGHT FIBERGLASS CABINET: Resistant to UV rays without rusting and ease of maintenance. FILTER PUMP CONTACTORS: Enables control of the filter pump via the Enersave's control board.
