Rheem AmbiPower280e Hot Water Heat Pump
Rheem AmbiPower® 280e Hot Water Heat Pump (280 L)
Ultra-efficient, low-running-cost hot water for NZ homes
The AmbiPower® 280e is Rheem’s next-generation 280 L hot water heat pump, designed as a direct replacement for a standard electric cylinder. Using R290 refrigerant and advanced wrap-around microchannel heating, it delivers reliable, low-cost hot water in all New Zealand climates — including cold and frost-prone regions.
Instead of heating water with electricity or gas, the AmbiPower extracts free heat from the surrounding air. This allows most households to reduce their hot water energy use by up to 70%, with a COP performance up to 5.2× more efficient than a traditional element heater.
