Hot Water Rebates, Tariffs & Savings
Right now, there is strong interest in Portland West in replacing old gas or electric hot water with efficient options like heat pumps, modern electric hot water or a solar hot water system. Homeowners can usually tap into a mix of Australian Government Small‑scale Technology Certificates (STCs) and Victorian hot water rebate programs that support heat pump hot water and solar hot water. These incentives effectively cut the hot water system price or cost by a substantial percentage, bringing the heat pump hot water price or cost and solar hot water price or cost down to something much more manageable. There are also electric hot water system rebate options in some programs when you are shifting away from gas.
For many Portland West homes, that means you can upgrade to an energy efficient hot water system and still enjoy a reasonable payback period, especially if you already have rooftop solar. Combining rebates, smart tariffs, timers or solar‑diversion controls can trim payback times to just a few years, while ongoing savings of hundreds of dollars per year add up quickly. When you weigh up heat pump vs solar hot water, or solar hot water vs electric hot water, it is worth considering your roof space, existing solar, tariff structure and whether you plan to go fully electric hot water vs gas hot water in the future.
