Hot Water Rebates, Tariffs & Savings
Across Attadale WA there is growing interest in replacing ageing gas storage units with a heat pump hot water system, efficient electric hot water system or a roof‑mounted solar hot water system. Federal incentives such as Small‑scale Technology Certificates (STCs) can lower the upfront solar hot water price or cost and heat pump hot water price or cost. On top of that, WA and other state‑based schemes periodically offer a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate to encourage households to move away from gas. These hot water rebate wa options can effectively shave a substantial percentage off the installed cost, shortening the payback period to just a few years, especially if you run the system on daytime solar.
With smart controls, you can use timers or solar‑diversion to heat water when your panels are producing, making your hot water wa upgrade even more efficient. For many Attadale households, that means hundreds of dollars a year off power bills, plus lower emissions.
