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 IHEAT 180L (sold commercially as the iStore 180L, model PASHW008-180LD-NM) is an all-in-one air source heat pump water heater: a single cabinet with the compressor and fan mounted above a coil-wrapped 180 L storage tank. It uses R290 (propane) refrigerant, delivers 2.5 kW of heating with a compressor power input of 0.58 kW, and is rated to operate down to -5 degrees C ambient (max 43 degrees C), drawing 700 cubic metres per hour of air across the evaporator.
The unit heats to a rated outlet temperature of 60 degrees C and carries a 1.0 kW electric booster element for one-shot backup heating. Sound output is 46 dB(A) at 1 m in an anechoic chamber. The tank stands 1957 mm high by 540 mm diameter and weighs 93 kg empty, with 3/4 inch water connections.
