Australian Government Small-scale Technology Certificates (STCs) help bring down the upfront solar hot water price or cost and heat pump hot water price or cost, while Victorian programmes can add a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate for eligible homes. These hot water rebate VIC incentives can effectively trim system cost by a substantial percentage, often shaving years off the payback period.
When you combine rebates, smart tariffs and rooftop solar, switching from electric hot water vs gas hot water to an energy efficient hot water system can save hundreds of dollars a year. Many Doncaster East households are using timers or solar diversion controls so their electric hot water system or heat pump runs mostly on free solar, turning it into one of the best heat pump hot water system strategies for long-term savings. For older units, timely hot water repair or solar hot water repair can buy time, but once a tank starts to fail, solar hot water tank replacement or a full hot water installation with a new energy efficient hot water system usually makes more financial sense.
