The register of solar water heaters includes a list of all solar water heater and air source heat pump models that are eligible for small-scale technology certificates under the Small-scale Renewable Energy Scheme.

All systems must be installed exactly as they are listed on the register, and their components accredited with AS/NZS 2712 to be eligible for certificates. If one or more components are missing or changed during the installation of the system, it will no longer meet the criteria as a solar water heater or an air source heat pump under the Renewable Energy (Electricity) Regulations 2001, and is not eligible for small-scale technology certificates.

Register of solar water heaters

The latest version of the solar water heater register is version 49.

• documentasset:Air source heat pump models​
• documentasset:Solar water heater models with a capacity of less than 700 L
• documentasset:Solar water heater models with a capacity more than 700 L

Information listed in the register

Information listed in the register is divided into 3 lists based on tank size and technology type including:

• solar water heater models with a capacity of less than 700 L (mostly domestic models)
• solar water heater models with a capacity of more than 700 L (mostly commercial models), and
• air source heat pumps with a volumetric capacity of no more than 425 L.

The model names used in the register are typically the manufacturing/engineering model names, which often differ from the commonly used marketing model name.

If you are unable to find a particular model in the register, please contact the manufacturer or retailer to find out if the model listed in the register is the exact model name used.

Small-scale technology certificate postcode zones

The Clean Energy Regulator has determined 5 postcode zones for air source heat pumps and 4 postcode zones for solar water heaters in Australia, which are used to calculate how many certificates a system is eligible for. Each zone is based on climate and solar radiation levels and represents the geographical area of the Australia postcodes used.

Download the documentasset:postcode zones for solar water heaters and heat pumps and learn how to calculate the number of small-scale technology certificates a solar water heater is entitled to.

Model eligibility dates in the register

The register of solar water heaters includes information about installation periods in which certificates may be created for a particular solar water heater model. The installation period eligibility is recorded under the headings ‘Eligible from’ and ‘Eligible to’ in the register.

The ‘Eligible from’ heading indicates the date that a particular solar water heater model was certified to the AS/NZS 2712:2007 standard.

The ‘Eligible to’ heading indicates the last date of the installation period in which certificates may be created for a particular solar water heater model.

Manufacturers must ensure models listed in the register continue to meet the conditions of a solar water heater under the Renewable Energy (Electricity) Regulations 2001. By law, the Clean Energy Regulator must remove solar water heaters in the register that do not meet the conditions of a solar water heater.
