We have published version 56 of the register of solar water heaters. It is effective as of today, 10 December 2025.
The register lists solar water heaters and air source heat pump models that are eligible for small-scale technology certificates under the Small-scale Renewable Energy Scheme.
Model names in the register can differ from the marketed model name. If you can't find a particular model in the register, contact the manufacturer or retailer to find out the name of the model used on the register.
