Residential SWH Documentation

For solar water heaters (flat-plate, evacuated tube, thermosiphon), the following documentation is required, as applicable to the system.

Test reports:

• Collector efficiency: AS/NZS 2535.1 or EN 12975 Performance Report.
• Tank Heat Loss: AS/NZS 4692.1 test report or >700L calculation report.
• Gas Booster Performance (for gas-boosted systems): AS/NZS 4552.
• Pump Test Report or Hydraulic Analysis: Determining pump flow rate and power consumption specific to collector array size or boost plant.
• AS/NZS 2712 Appendix F No-load system operation test. One test may cover a family of systems (see AS/NZS 2712 App. F3).

Technical details:

• System Schematic including:
  • Collector model and number of collectors.
  • Storage tank model and number of tanks.
  • Solar pipework dimensions.
  • Pump model(s) and positions in the system.
  • Heat exchanger(s) and position in the system.
• Tank Drawings: Show height/volume above all fittings, elements, and sensors.
• Heat Exchanger Specifications: HX length, inner diameter, tube thickness, conductivity.
• Electric Booster: Capacity (kW) and thermostat settings (Set point and dead-band, e.g., 60°C and 8°C).
• Control Logic Specifications: pump differential temperature settings, frosting settings, maximum tank temperature settings.
• Flow Rate Specifications: and demonstration of flow rate control, such as via a flow meter or flow rate controller (may be demonstrated by the installation manual).
• Pipework Insulation Specifications: Thickness and thermal conductivity (as specified by the installation manual).

The Following Items Can be Provided by EnergyAE If Unavailable:

• Tank Heat Loss Calculation: For tanks >700L volume if test reports are not available.
• Hydraulic Analysis: of pump flow rate and power consumption if a pump test report is not available for a specific collector array.
• System Schematics.
• Improvements to Tank Drawing/System Schematics: In order to meet CER requirements.

Naming Conventions for Solar Water Heaters:

• BrandName_VEU_Submission
  • ModelNo1
  • BrandName_ModelNo_TRNSYS_Decks
    • BrandName_ModelNo_ESC_Z.dck*
    • BrandName_ModelNo_ESC_Z.lst*
