Commercial HPWH Documentation Checklist
Commercial HPWH scheme applications are based on system configurations, not only the heat pump model. The evidence pack needs to describe the heat pump, tank, control logic, pipework, pumps, storage volume, and submission entity clearly enough for modelling and later audit.
What this applies to
This checklist applies to commercial air-to-water HPWH systems being prepared for VEU Activity 44, ESS IHEAB, or AS/NZS 4234 modelling for commercial certificate estimates.
Documents required
| Document | Why it is needed |
|---|---|
| EN 14511 test report | Provides the heat pump performance map for commercial modelling. |
| AS/NZS 4692.1 test report | Required for tanks up to 700 L. |
| Tank drawing | Provides tank geometry, connection heights, element locations, and insulation details. |
| System schematic | Defines the system layout modelled for VEU or ESS. |
| Pipe insulation specification | Supports pipe heat loss modelling. |
| Pump performance curve | Confirms flow capability and system behaviour. |
| Control logic or declaration | Confirms setpoints, deadbands, sensors, boost logic, and legionella control. |
| Bill of materials | Confirms component models and quantities in each submitted system. |
| AS/NZS 2712 certificate | Required for tanks up to 700 L where applicable. |
| Installation manual | Supports submission and cross-checks settings, plumbing, and warranty claims. |
| Data plate images | Confirms model names, ratings, refrigerant type, and refrigerant charge. |
EN 14511 test report
The EN 14511 report is the primary input for the heat pump performance map.
Check that the report includes the tested model name, air dry bulb and wet bulb temperatures, water inlet and outlet temperatures, heating capacity, input power, COP, and units for every reported value.
The report should also include standby power if measured, along with laboratory details and a signature or validation.
The test matrix should be selected before testing starts. Commercial scheme modelling needs performance over a useful range of air and water inlet temperatures.
Tank evidence
For tanks up to 700 L, provide an AS/NZS 4692.1 test report from an accredited laboratory.
For tanks greater than 700 L, EnergyAE needs enough drawing information to calculate heat loss from the tank geometry and insulation properties. The drawing should state internal diameter, internal height, total internal volume, insulation thickness on the wall, top, and bottom, insulation material or thermal conductivity, and connection heights for inlet, outlet, flow, return, sensors, and elements.
System schematic
The schematic should show the exact system to be submitted.
It should include heat pump model and quantity, tank model and quantity, pump locations, flow direction, sensor locations, control valves, boost plant if fitted, pipework between heat pump and tank, and the multi-tank arrangement where relevant.
Control information
The control description should be specific enough to reproduce in a simulation model.
Provide the heat pump on and off conditions, the sensor used for control, pump flow rate or variable flow logic, target outlet temperature if variable flow is used, boost setpoint and deadband, and legionella control temperature and frequency.
Also identify any demand response, timer, or lockout behaviour that will apply in the field.
What EnergyAE needs from you
Provide the latest version of each document and confirm which model names will appear in the public scheme listings.
If the product will be sold under a local brand rather than the original manufacturer brand, resolve the branding and certificate schedule before submission evidence is prepared.
