Hot Water Rebates, Tariffs & Savings
For Pennington households thinking about hot water repair or a full hot water installation, federal and state incentives can make the decision easier. The Australian Government’s Small‑scale Technology Certificates (STCs) help cut the upfront solar hot water price / cost or heat pump hot water price / cost, and South Australian programs often add a state‑based heat pump hot water rebate or solar hot water rebate on top. There are also electric hot water system rebate options when moving away from gas hot water. Together, these hot water rebate sa schemes can reduce the effective hot water system price / cost by a substantial percentage, often turning a five‑ to seven‑year payback into something much shorter. When you combine an energy efficient hot water system with rooftop solar, smart tariffs, timers or solar diversion, it is common to save hundreds of dollars a year on bills.
