Hot Water Rebates, Tariffs & Savings
Homeowners in Worrolong are increasingly replacing old gas or ageing electric units with efficient options like heat pumps, smart electric hot water system upgrades and modern solar hot water systems. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively reducing the solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, state programs can offer a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate, helping Worrolong households cut the upfront hot water system price / cost by a substantial percentage.
When you add these rebates to bill savings of a few hundred dollars per year, the payback period for a heat pump hot water installation or solar hot water repair and upgrade can shrink to just a handful of years. Using timers or solar diversion to run an electric hot water installation during the middle of the day can push savings even further, especially for homes with rooftop PV. For many, moving to hot water SA solutions that are efficient and electric is also a chance to step away from gas entirely and enjoy a quieter, cleaner all‑electric home.
