Hot Water Rebates, Tariffs & Savings
Around Culham, more households are weighing up electric hot water vs gas hot water and looking at efficient alternatives. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively working as an upfront solar hot water rebate or heat pump hot water rebate that reduces the sticker price. WA programs and retailer offers can sometimes add extra discounts, and there may be an electric hot water system rebate available when you switch away from gas. Together, these hot water rebate WA incentives can knock a substantial percentage off the installed heat pump hot water price or cost or the solar hot water price or cost, shortening payback times to just a few years in some cases. When you combine an energy efficient hot water system with rooftop solar, smart timers or solar diversion, many homes can save hundreds of dollars a year on bills.
