Physics-based HPWH Diagnostics and Tuning

EnergyAE now offers heat pump water heater (HPWH) diagnostics using physics-based component-level modelling and in-house expertise. Unlike AS/NZS 4234 compliance modelling, which is limited to control settings, sensor placement and little more, our component-level modelling looks inside your system to explain what is driving performance, component by component, so you know what to change and why.

• Are heat exchangers undersized?
• Is the system over or under-charged?
• Are the control systems tuned optimally, including temperature setpoints and compressor frequency maps?
• How should the tank be sized and the inlets/outlet and heat exchangers arranged?

MEPS Simulation

EnergyAE runs your product through a validated simulation of the AS/NZS 5125.1 Appendix H test protocol, interprets the results, and provides design recommendations before you commit to physical testing. With Chinese laboratory retests costing tens of thousands of dollars including shipping and delays, one avoided retest covers the consulting engagement many times over.

• Simulate all three Appendix H test sequences at each of the three required ambient conditions
• Identify likely failure modes and quantify margin to the MEPS threshold before physical testing
• Recommend design or control changes to optimise first-time pass probability
• Applicable to new products and existing products being assessed for MEPS compliance

Incentive Scheme Pre-assessment

Using TRNSYS simulation against AS/NZS 4234, we model your product's predicted certificate yield before formal scheme registration. The same design and control logic that drives MEPS performance also determines incentive scheme outcomes, so this analysis covers both in a single engagement.

• Predict STC and VEEC yields for proposed or existing designs
• Identify control and design changes that improve scheme performance
• Align optimisation across MEPS and incentive scheme requirements in one pass

Collaboration

We collaborate with manufacturers, government agencies, and research institutions to advance clean energy technology. Our team has contributed to projects at leading Australian and international universities.

EnergyAE is an active member of the CS-028 Australian Standards committee, contributing to the development of standards that govern energy efficient water heating products.
