Hot Water Rebates, Tariffs & Savings
Across WA, there is growing interest in replacing old gas or electric hot water with efficient options, and Arrino is no exception. Even in a small community, more households are looking at heat pump hot water installation, solar hot water installation and smarter electric hot water installation that works with rooftop solar. A key driver is the range of Australian Government incentives and state‑based support that can reduce the upfront cost of going efficient.
Most new solar hot water and heat pump systems are eligible for Small‑scale Technology Certificates (STCs), which effectively act as a solar hot water rebate or heat pump hot water rebate, applied as a discount off the purchase price. Depending on the system size and efficiency, these discounts can cut the installed cost by a substantial percentage. Some all‑electric upgrades may also benefit from an electric hot water system rebate or broader electrification programs that reward moving away from gas. For many Arrino homes, that means the payback period on an upgrade can fall to just a few years, especially if you already have solar and use timers or solar‑diversion to heat water in the middle of the day.
With energy prices rising, it is common to see total savings of hundreds of dollars per year from an efficient hot water upgrade in Arrino, WA. When you factor in the hot water rebate WA schemes and federal incentives, the long‑term numbers are even more compelling.
