What's inside
- → What the certificates are worth: median certificates per installation by heat pump size, for Victoria and New South Wales
- → The 2027 step in New South Wales, where the Confidence Factor falls from 1 to 0.7 for installations from 1 January 2027
- → The eligibility floors, settled at design: 425 L average storage in Victoria, 45°C delivered temperature, 60% annual savings and the 10 kW average capacity penalty
- → Test: EN 14511 or AS/NZS 5125.1 heat pump data, AS/NZS 4692.1 heat loss tests, and what changes at the 700 L line
- → Model and certify: Peak Load by climate zone, AS/NZS 2712 per distinct tank, and the five-year warranty rule
- → VEU and ESS compared in one table, from assessment times to the Victorian customer co-payment and the 5,000 certificate cap
- → A timeline and the document set both schemes want, so the application is complete when it is lodged
Who this is for
Manufacturers, distributors and system integrators selling large heat pump water heater systems into Victoria and New South Wales, and the sales managers who need to know what a system is worth to a customer before quoting it.
Need it done, not just mapped?
EnergyAE runs this end to end: eligibility checks, AS/NZS 4234 modelling by climate zone, certification evidence, and submission to both schemes.
