Hot Water Rebates, Tariffs & Savings
For Seaton households, the economics of upgrading are helped by generous hot water rebate programs. At a federal level, Small‑scale Technology Certificates (STCs) cut the effective hot water system price for eligible systems like a solar hot water system or heat pump hot water system. South Australian schemes have also offered a heat pump hot water rebate and solar hot water rebate at various times, and some energy retailers provide discounts when you move to controlled‑load tariffs or smart timers. Together, these can slash the upfront heat pump hot water price or solar hot water price by a substantial percentage.
There are also incentives for efficient electric hot water system rebate offers when you replace old gas units as part of broader electrification programs. For many Seaton homes, that means a heat pump vs solar hot water decision comes down to roof space, budget and how much daytime solar you have. Combine rebates with smart controls or solar diversion and it is common to see payback periods of just a few years, especially when you are replacing an old, inefficient unit or doing a solar hot water tank replacement.
