Rheem AmbiPower MDc-180Heat Pump Hot Water System
Perfect for 1–3 people. The Rheem AmbiPower MDc-180 uses R290 refrigerant with a COP of up to 3.6, delivering up to 70% in energy savings over conventional electric hot water. Built-in frost protection operates down to -7°C. Backed by a 5-year heat pump and 10-year cylinder warranty.
Rheem AmbiPower MDc-180 — Up to 70% Energy Savings
The Rheem AmbiPower MDc-180 works by extracting heat from the surrounding air and transferring it to your water — using up to 70% less electricity than a conventional electric element. Backed by over 85 years of Rheem engineering in Australia.
Up to 70% Less Energy
With a COP of up to 3.6, the Rheem AmbiPower MDc-180 is highly efficient. For every 1 unit of electricity consumed, the system produces up to 3.6 units of heat energy — dramatically reducing running costs.
Frost Protection to -7°C
Built-in frost protection means reliable hot water year-round. The system operates efficiently down to -7°C ambient temperature, making it suitable for all Australian climates.
R290 Natural Refrigerant (GWP=3)
R290 (propane) is a 100% natural refrigerant with near-zero global warming potential (GWP=3) and zero ozone depletion potential. It is one of the most environmentally responsible refrigerants available and is future-proofed against regulatory changes.
