Reduce energy consumption and the environmental impact of your heating and cooling equipment by harnessing energy that is already being produced but not used. This includes high-efficiency, variable-speed EC condenser fans with integral head pressure control and an acoustical design that provides low operating noise levels. The packaged air-cooled SHC onDEMAND® provides hot water as high as 140°F (60°C) while offering a minimum cooling efficiency of 10.0 EER and typical heating efficiencies around 3.0 COP.
