Hot Water Rebates, Tariffs & Savings
For Wattle Park residents, generous incentives can bring the hot water system price or cost down significantly. Federal Small‑scale Technology Certificates (STCs) reduce the upfront solar hot water price or cost and the heat pump hot water price or cost, while South Australian heat pump hot water rebate and solar hot water rebate programs may apply to eligible homes. There are also electric hot water system rebate options in some schemes, particularly when replacing old gas units with an energy efficient hot water system.
