Hot Water Rebates, Tariffs & Savings
Across Williams and wider WA, more households are now replacing old gas or ageing electric units with a heat pump hot water system, a newer energy efficient electric hot water system or a solar hot water heating system. Australian Government incentives, such as Small‑scale Technology Certificates (STCs), can reduce the effective hot water system price or solar hot water price by a substantial percentage at the point of sale. State‑based support can also act like a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate, bringing down the heat pump hot water price or overall hot water system cost.
