Hot Water Rebates, Tariffs & Savings
Clapham homeowners are increasingly replacing old gas hot water with a heat pump hot water system, or upgrading to a modern electric hot water system paired with solar, to lock in lower bills. There are Australian Government incentives through Small‑scale Technology Certificates (STCs) that apply to eligible solar hot water systems and heat pumps, effectively acting as an upfront discount off the solar hot water price / cost or heat pump hot water price / cost. On top of that, South Australian programmes can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when switching away from gas. These hot water rebate SA offers can slice a substantial percentage off the total hot water system price / cost, shortening the payback period to just a few years in many cases.
By combining rebates with rooftop solar, smart tariffs and timers that run the system in the middle of the day, Clapham households can often save hundreds of dollars per year. Using solar‑diversion to heat water when the panels are producing can turn your tank into a thermal battery, making an energy efficient hot water system a cornerstone of an all‑electric home.
