Commercial Heat Pump Water Heater (HPWH)

Commercial Heat Pump Water Heater (HPWH) logo
Heat pump water heaters (also called hybrid water heaters) combine energy-saving heat pump technology with traditional electric elements. With a heat pump water heater, you get the same reliable hot water while using up to 60% less energy.

Unitary heat pump water heaters combine the tank and compressor in a single unit, while split-system heat pump water heaters have interior storage tanks and outdoor compressors installed outside the building
  • Reduce water heating cost by up to 60%
  • Many models offer leak detection and Wi-Fi connectivity
  • Most units have additional controls, such as temperature and away settings
