Rheem Ambiheat HDc270Heat Pump Hot Water System
Perfect for 2–4 people. The Rheem Ambiheat HDc270 uses R32 refrigerant with a COP of up to 3.4, delivering up to 65% 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 Ambiheat HDc270 — Up to 65% Energy Savings
The Rheem Ambiheat HDc270 works by extracting heat from the surrounding air and transferring it to your water — using up to 65% less electricity than a conventional electric element. Backed by over 85 years of Rheem engineering in Australia.
Up to 65% Less Energy
With a COP of up to 3.4, the Rheem Ambiheat HDc270 is highly efficient. For every 1 unit of electricity consumed, the system produces up to 3.4 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.
R32 Refrigerant — Lower GWP
R32 has a significantly lower global warming potential than older refrigerants like R410A (GWP 2088), making it a more eco-responsible choice for the environment.
