Colmac heat-pump water heaters (HPWH) offer commercial and industrial users of sanitary hot water an energy-efficient means of heating water to temperatures as high as 185°F (85°C) in a single pass. These heat-pump water heaters use the same operating principle as an air-conditioner or domestic refrigerator. The heat pump gathers heat from the surrounding air, and through the refrigeration cycle, deposits the heat into water at a useable temperature. This principle of moving heat with a heat pump, rather than generating it by burning fossil fuels (e.g. natural gas), or electric resistance, makes water heating with heat pumps ideal for conserving energy. Depending on the temperature of the source air or water, domestic water can be heated using one third to one fourth of the energy required by electric resistance or gas. Colmac heat pump water heaters are the best choice for realizing ambitious building electrification and sustainability goals in New York City and across North America.
