The Australian Government’s Small‑scale Technology Certificates (STCs) effectively act as an upfront discount off the heat pump hot water price / cost or solar hot water price / cost, while South Australian schemes can add a dedicated heat pump hot water rebate or solar hot water rebate for eligible systems. In some cases, the combined hot water rebate SA residents can access can slice the system cost by a substantial percentage and cut the payback period to just a few years. There are also programs that support an electric hot water system rebate when moving away from gas, making electric hot water vs gas hot water a much easier decision. With smart timers or solar‑diversion controls, you can run your hot water system mainly on your own solar, improving savings even further.
