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, mapped end to end by the consultancy that runs it for manufacturers and importers every week. It covers the design choices that set the ceiling on everything downstream, what each of the three schemes asks for, and what EnergyAE runs at each step.

What's inside

  • The five steps in order: design, test, model, certify, register, with what EnergyAE runs at each one
  • Design: topology, refrigerant, compressor, tank and control settings, and what each choice locks in before a single test is booked
  • Test: every standard your product has to pass, with lead times, what triggers a retest, and the laboratories that do the work
  • Model: AS/NZS 4234, the zones and load sizes each scheme asks for, and the five minimum criteria a result has to meet
  • Certify: AS/NZS 2712, electrical safety certification and WaterMark, and the accredited bodies that issue each one
  • Register: STC, VEEC and ESC at equal depth, with all three schemes' eligibility conditions side by side and the full document set
  • Realistic lead times and a launch-planning Gantt, so a launch date is a plan rather than a guess

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.
