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, medium household, calculated from the model's registered performance data.
The iStore 180L (PASHW008-180LD-NM) is an integral heat pump water heater: the compressor, fan and evaporator sit inside the same cabinet as the 180 L tank, with the condenser coil wrapped directly around the tank rather than a separate outdoor unit. WaterMark certification (026240) describes it as a “180 litre integral heat pump hot water heater,” consistent with the manual’s single-cabinet design.
The single rotary compressor delivers 1.7 kW of heating capacity at a rated power input of 1.7 kW, drawing 7.1 A, and runs in ambient temperatures from -5 to 43 degrees C. Sound output is 46 dB(A) at 1 m. The unit ships with a 1.0 kW electric booster restricted by the Clean Energy Regulator to a single one-shot heat cycle, and the controller runs a mandatory weekly anti-legionella cycle at midday. Delivered water temperature is factory-set to 60 degrees C.
The 180L cabinet stands 1957 mm tall with a 540 mm diameter, net (empty) weight 93 kg. The same physical product is also sold and manual-branded as an “iStore” heat pump; IHEAT is the scheme-registered brand name for this model.
