AetherMax 320L Heat Pump Hot Water System

Powerful capacity. Smarter energy use. Hot water designed around modern family life.
The AetherMax 320L Heat Pump Hot Water System brings together generous capacity, high-efficiency heat pump technology, intelligent controls and solar-friendly operation in one modern all-in-one system.

Designed for households of around 5–7 people, it provides the capacity larger families need while offering a smarter approach to everyday hot water.

High Efficiency Without Compromising Everyday Performance
At the heart of the AetherMax is its manufacturer-published COP of up to 5.15 in Economic Mode.

COP, or Coefficient of Performance, measures the relationship between heat delivered and electricity consumed under specified operating conditions.

In Economic Mode, the AetherMax has published figures of 3.3 kW heating capacity, 0.64 kW rated input, COP 5.15 and a 62 L/h recovery rate.

For homeowners replacing traditional electric hot water, that difference in technology can make heat pumps an attractive option when looking at long-term household energy use.

Actual performance will naturally vary with ambient temperature, water temperature, system settings, installation conditions and household demand.

One System. Four Ways to Heat.

Family life does not follow the same routine every day, so the AetherMax provides four operating modes.

Economic Mode - COP 5.15: prioritises energy-efficient everyday operation.
Standard Mode - COP 5.0: balances efficiency with faster recovery.
Booster Mode - COP 2.47: provides increased recovery when hot-water demand rises.
E-Heater Mode - COP 1.0: uses the 1.2 kW electric element when required.

Warranty Designed for Long-Term Ownership

The AetherMax's published warranty includes 7 years parts and 5 years labour on the tank/cylinder, subject to warranty conditions and the specified major-service requirement for parts coverage in years six and seven.

The refrigeration system carries 5 years parts and labour, while electrical and control components have 5 years parts and 2 years labour coverage. Serviceable components have 1 year parts and labour coverage. Read more
