Hot Water Rebates, Tariffs & Savings
Right now, there is strong interest in Wedge Island in replacing old gas or basic electric units with efficient options such as heat pump hot water, a modern electric hot water system paired with rooftop solar, or a roof‑mounted solar hot water system. Federal incentives through Small‑scale Technology Certificates (STCs) reduce the upfront solar hot water price / cost and heat pump hot water price / cost, while South Australian schemes can add a heat pump hot water rebate or solar hot water rebate for eligible homes. In some cases, an electric hot water system rebate can apply when moving away from gas to efficient electric. These discounts can effectively cut the hot water system price / cost by a substantial percentage and shorten payback times, especially when combined with solar PV and smart timers or solar diversion controls. For many Wedge Island homes, that means hundreds of dollars a year off bills and a payback that can drop to just a few years.
