Certificate counts are computed from the model's registered performance data using the current regulated equations. A lodged claim depends on the specific installation, household size, and the scheme rules in force at creation. Energy savings % is against the AS/NZS 4234:2021 reference electric storage water heater for that zone and load size, calculated from the model's registered performance data, or taken directly from the register where it publishes a savings figure. VEU registers this data at the small load (the step-down load for a medium-rated system) and ESS at the medium load, so the two schemes' figures differ for the same zone.
The Omni X OMNIXHPGL-320-R290 is an integral heat pump water heater: a DC inverter R290 (410 g) heat pump and 320 L glass-lined storage tank combined in a single cabinet (650 mm diameter, 2090 mm tall, 146 kg empty). It operates across an ambient range of -7 to 46 degrees C and is rated at 43 dB(A).
The manufacturer quotes a COP of “up to 5.2”, though no test condition is published for that figure. A 1.6 kW electric backup element is fitted, and the unit ships with smart WiFi control and an LCD controller.
The OMNIXHPGL-320-R290 is the largest of a three-model Omni X glass-lined range (210, 270 and 320 L) sharing the same compressor platform and warranty: 7 years on the tank, 5 years on the compressor and other components.
