Rheem Digital Heat Pump with Power Defrost 119K BTU 208/230V comes with a polyester powder-coated, non-corrosive cabinet that is more durable than plastic heat pump cabinets. This heat pump also features raised lanced-fin design that maximizes heating at lower temperatures. The scroll compressor provides high efficiency, low sound levels, and durability. This heat pump also features Heat-Cool units which have the ability to prevent ice from forming on the condensing coil within 4-6 minutes. During the cooling mode, the refrigerant will be warmed by the pool water and send the hot gas to the evaporator coil to melt the ice. Once returned to a normal operating temperature, the unit resumes heating the water.
