Manufacturers guide

For manufacturers of solar water heaters (SWHs) and air source heat pump water heaters

Solar and heat pump water heater models are only eligible to have small-scale technology certificates (STCs) created against them under the Small-scale Renewable Energy Scheme (SRES) if they are listed in the Register of solar water heaters.

Eligibility requirements

All solar water heaters may only be considered for listing in the Register of solar water heaters if it meets the eligibility requirements. Different requirements apply to models depending on their storage capacity.

All air source heat pump water heaters must be calculated using the new methodology, including zone 5, to continue being eligible for small-scale technology certificates after 31 October 2012.

  • For solar water heater models with storage capacity of 700 litres or less – a conformity assessment body must have given the model product certification to Australian and New Zealand Standard 2712:2007 (AS/NZS 2712:2007).

    Note: only air source heat pump water heaters with storage capacity of no more than 425 litres are eligible under the Small-scale Renewable Energy Scheme.

  • For solar water heater models with storage capacity greater than 700 litres – a conformity assessment body must have given the components that make up the solar water heater certification to the Australian Standard(s) relevant to that part of the solar water heater. The list of relevant standards can be found in clause 1.3 of Australian and New Zealand Standard 2712:2007.

    Models with storage capacity greater than 700 litres must also meet the storage tank requirements set out in Australian Standard 4692.1:2005 as in force on 27 September 2005; or the requirements set out in Heat loss test procedure for solar water heaters with a hot water storage tank greater than 630 litres (Word 270 KB).

Process for including solar or air source heat pump water heaters in the Register of solar water heaters

  1. Call for applications

    The Clean Energy Regulator calls for applications from manufacturers to update the Register of solar water heaters on a regular basis, normally every three months. Each application round is advised on the Clean Energy Regulator website and registered stakeholders are advised via email. The application period is open for at least 30 days.

    Subscribe to receive email updates about the Register of solar water heater, including application rounds.

  2. Preparing an application

    Applicants must complete and lodge the Register of solar water heater application form and required supporting documents. All applicants must ensure that audit files are prepared correctly at the time their application is submitted.

    See updating the Register of solar water heaters for more information about the application requirements.

    All applications must be submitted before the closing date so that applications may be reviewed and amended if necessary. Incomplete or late applications will not be accepted.

  3. Assessing applications

    The Clean Energy Regulator checks all models listed in the applications against the Australian and New Zealand Standard AS/NZS 2712:2007 licensing schedule. Models that are not correctly listed in the submission will not be accepted.

    The Clean Energy Regulator also audits selected models to ensure their small-scale technology certificate entitlements are calculated correctly. During the audit process, the Clean Energy Regulator will request supporting information such as test reports and TRNSYS files. Models that have not had their small-scale technology certificate entitlements calculated correctly will not be listed. Applicants must be able to provide the Clean Energy Regulator with the requested documentation, within the specified timeframe.

  4. Finalising and publishing the Register

    Applicants are provided with a final opportunity to review the draft Register of solar water heaters before its publication to ensure that models are listed correctly.

    Once finalised, the Register of solar water heaters is published on the Clean Energy Regulator website. Once the Register is published small-scale technology certificates may be created for newly listed models.

Conformity assessment body

Certification to AS/NZS2712 must be provided by a Conformity Assessment Body (CAB) accredited under the Joint Accreditation System of Australia and New Zealand (JAS-ANZ).

Contact the Joint Accreditation System of Australia and New Zealand for information on conformity assessment bodies currently accredited to certify products to AS/NZS 2712:2007, how to become a conformity assessment body and the process of demonstrating that products meet relevant standards.
