Efficient hot water for smaller households.
Recommended for: 3–5 people
Reliable everyday performance for families.
Recommended for: 5–7 people
High-capacity hot water for larger homes.
The AetherMax 320L captures heat from the surrounding air and transfers that energy into the water stored inside its integrated tank. This allows the system to produce everyday hot water efficiently while reducing reliance on direct electric resistance heating during normal heat pump operation.
Its 320L capacity is designed for larger households of approximately five to seven people. Four operating modes provide flexibility between maximum efficiency, everyday operation, rapid hot water recovery and electric element support.

The 320L tank is designed to support the everyday hot water needs of households with approximately five to seven people.
Uses natural R290 refrigerant with a listed factory charge of 395g.
The brochure lists a maximum input current of 9.8A, supporting connection to a suitable 10A electrical supply.
AetherSmart supports instant alerts, remote diagnostics and faster service resolution.
