Free tools for the heat pump water heater market
Five tools built on the same data and modelling EnergyAE uses for client work: the public CER, VEU and ESS registers, annual AS/NZS 4234 simulations of calibrated product models, and a Python implementation of the AS/NZS 5125.1 Appendix H MEPS test. All are free to use and need no login.
Incentive calculators
Certificate boards for SRES, VEU and ESS, built from the live public registers. See how many STCs, VEECs or ESCs every registered heat pump water heater earns, in the climate zone an install sits in.
Open →HPWH lifetime cost calculator
Compare the lifetime running cost, savings and emissions of heat pump water heaters against electric storage and gas, by climate zone and household size. Running costs come from an annual AS/NZS 4234 simulation of each product’s own calibrated model, not a nameplate COP.
Open →Commercial incentive estimator
Estimate the VEEC (Victoria) and ESC (NSW) certificate range for a 10–200 kW commercial heat pump water heater from its capacity, tank and refrigerant, shown as a typical midpoint and a P10–P90 range.
Open →HPWH database
Specs and government rebate values for every residential heat pump water heater in the Australian market. Filter, sort by rebate and compare up to four models side by side.
Open →MEPS testing simulator
Watch the AS/NZS 5125.1 Appendix H MEPS test sequence run end to end: heat-up, the maximum draw-off that sets V50, re-heat, and the 24-hour tapping cycle. Change tank volume, control-sensor position, dead band, ambient condition and declared load size.
Open →AU/NZ HPWH Foundations course
An online course for anyone working in the Australian and New Zealand heat pump water heater industry: testing to AS/NZS 5125.1, AS/NZS 4234 modelling, the SRES, VEU and ESS schemes, and product approvals. Short videos, written lessons and quizzes, with a certificate at the end. Join the waitlist for founding places.
Open →Need a figure you can put in a business case?
These tools estimate from published register data and generic assumptions. Certificate counts for a specific product come from AS/NZS 4234 modelling of that unit, which is the work we do for manufacturers and importers.
