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 AKQUA AK-200HPE1 is a 200 L (204 L physical volume) all-in-one integral heat pump water heater using R290 refrigerant. It carries a built-in electric element for boost operation, delivers hot water up to 75 degrees C, and runs at a quoted sound level of 43 dBA.
The model is listed on the Clean Energy Regulator’s air source heat pump model list with STC zone certificate ratings across all five Australian climate zones, and is registered under the SRES, VEU, and ESS schemes under the AKQUA brand.
Warranty is 5 years on the tank cylinder (3 years labour), 3 years on the compressor (1 year labour), and 1 year on electronics, parts, and labour. Detailed capacity, power input, COP, and dimensional figures were not found in publicly accessible AKQUA documentation at time of writing.
