Reduce your water heating electricity use with the Rheem AmbiPower 280e. This 280L heat pump water heater draws warmth from the surrounding air and transfers it into your water, providing an efficient alternative to traditional electric storage water heating without relying on direct sunlight.
280L Storage Up To 6 People R290 Refrigerant Electric Backup ElementThe AmbiPower 280e provides 280 litres of water storage.
Allow approximately 5 hours to heat a fully cold tank using the heat pump, based on an air temperature of 19°C and heating water from 15°C to 60°C. This is a calculated estimate; colder conditions can increase heating time.
This water heater requires electricity. For an off-grid installation, the power system must accommodate both heat pump operation and the higher demand of the backup element. Discuss suitability with your installer before purchasing.
Have the unit installed by qualified professionals, with the location, airflow, drainage, plumbing and electrical supply assessed before installation. Allow additional space around the unit for airflow and servicing, as specified in Rheem’s installation instructions.
As a general budgeting guide, allow approximately $2,000–$4,000 for installation. This is an indicative allowance, not a fixed quote. Complex installations or electrical upgrades may cost more. Your local installer can provide an accurate price for your property.

The AmbiPower 280e has a water storage capacity of 280 litres.
Allow approximately 5 hours to heat a fully cold tank using the heat pump under the conditions listed above.
This estimate is calculated from Rheem’s published recovery rate rather than a guaranteed heating time. Weather conditions, incoming water temperature and hot water drawn during heating will affect the result.
It requires electricity to operate. The heat pump extracts warmth from the surrounding air, so direct sunlight is not required.
It may be suitable where the power system can support its electrical demand. Your installer should assess inverter capacity, battery storage, available generation and backup element operation before recommending it for your setup.
Consider shower duration, baths and how many people use hot water close together. Ask your installer to assess storage capacity and recovery time against your household’s daily routine.
The heat pump operates within its specified temperature range. Outside that range, the electric element provides heating when required. Cold weather can increase heating time and electricity use.
Your installer should assess the location and any protection required for exposed plumbing in frost-prone areas.
Allow approximately $2,000–$4,000 as a general budgeting guide. Complex installations may cost more. Obtain a tailored quote from your local qualified installer.
