Hot Water Rebates, Tariffs & Savings
Across Delamere there is growing interest in replacing ageing gas and electric units with efficient options, helped by a range of hot water rebate SA programmes. Eligible systems can generate Small‑scale Technology Certificates (STCs) under the Australian Federal Government scheme, which effectively discount the upfront hot water system price / cost at the point of sale. On top of that, South Australian heat pump hot water rebate offers and solar hot water rebate schemes can further reduce the cost of a compliant solar hot water system, heat pump hot water system or even a qualifying electric hot water system rebate pathway when switching away from gas.
For many Delamere homes, these combined incentives can cut the installed cost of a quality system by a substantial percentage and shorten payback to just a few years, especially when paired with rooftop solar and smart controls. Using timers or solar‑diversion devices to run a heat pump or electric hot water system during the middle of the day lets you soak up excess solar and turn your cylinder into a thermal battery. That is where the most efficient hot water system really shines, lowering bills and smoothing your overall energy use.
