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.
Up to 70% lower running costs compared to electric storage cylinders
Rheem reliability backed by a 7-year warranty
Performs in cold climates (operating range: -6°C to 45°C)
Low-noise side-fan design ideal for urban sections
Durable aluminium and coated steel exterior for long NZ outdoors life
User-friendly LED touchscreen for easy temperature and mode control
No reliance on sunlight — works day or night, rain or shine
The AmbiPower 280e is ideal for:
Homes with 2–5 people
Replacing an existing mains-pressure electric cylinder
Homes wanting lower power bills
Properties without natural gas
Homes wanting a low-maintenance, long-life hot water solution
Clearance needed: 696W × 725D × 1832H
Installation location: Outdoor
Power: Standard connection (installer will confirm)
Hot water heat pump installation varies by property, but most customers fall within:
$2,000–$3,000 – Straight cylinder replacement
$2,500–$4,000 – Standard retrofit
$3,500–$5,000 – Complex installations / electrical upgrades
For an exact quote, we recommend speaking with your local registered plumber or gasfitter.
