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 Goodheat GHWVSH-320AA1 is an integral heat pump water heater: an R290 (propane) microchannel heat pump and a 320 L storage tank are built into a single all-in-one cabinet, packaged at 168 kg. It shares its platform, model naming (OMNIXHPGL-320-R290) and manufacturer with the Omni X Technologies range, and is sold under the Goodheat brand with an AA1/AB1 colour or finish variant pair on the register.
The default heat pump setting targets 60 degrees C, though the manual’s system parameter table shows the electric element setting as not applicable for this model, unlike the 210 and 270 L units which list a below -7 degrees C electric backup threshold. A weekly automatic sterilisation cycle heats part of the tank to 61 degrees C. The manual states the appliance delivers water not exceeding 50 degrees C in accordance with AS 3498, and requires a minimum indoor installation area of 75 square metres.
Warranty covers the storage tank and compressor for 5 years each, with other components (valves, elements, thermostats, anodes) also covered for 5 years.
