The 2026 AU Residential HPWH Guide: Design, Test, Model, Certify, Register
The five steps that take a residential heat pump water heater from a design decision to a listed, incentive-eligible product in Australia, in a short landscape format built to be read in one sitting. It covers the design choices that cannot be undone once testing starts, what each of the three schemes asks for, and the work EnergyAE runs at each step.

What's inside
- → The five steps in order, with what EnergyAE runs at each one and a checklist to clear before the next
- → Design: the choices that cannot be revised after testing, namely refrigerant, tank volume, control sensor position and tank lining class
- → Test: the five laboratory streams, which one sets the critical path, and what sends a product back for a retest
- → Model: AS/NZS 4234:2008 for SRES and 2021 for VEU and ESS, and the five minimum criteria a result has to meet
- → Certify: AS/NZS 2712, the electrical Certificate of Conformity and WaterMark, and the bodies that issue each
- → Register: STC, VEEC and ESC in one comparison table, with the documents each submission needs from you
- → A timeline and critical-path chart, so a launch date is a plan rather than a guess, and the 2026 market picture from the Clean Energy Regulator
Who this is for
Product and compliance managers at HPWH manufacturers and importers (commonly Chinese or Japanese-manufactured units) bringing a residential product to the Australian market, and the sales or channel managers who need a certificate number to quote.
Need it done, not just mapped?
EnergyAE runs this end to end for manufacturers and importers: testing advisory, AS/NZS 4234 modelling across all three schemes, documentation QA, and submission.
