Homeowners in Balwyn can usually access a mix of Australian Government incentives and Victorian hot water rebate VIC programs when installing an energy efficient hot water system. Small‑scale Technology Certificates (STCs) effectively discount the upfront solar hot water price / cost and heat pump hot water price / cost at the point of sale. On top of that, state schemes can provide a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate for eligible upgrades, cutting the real hot water system price / cost by a substantial percentage. When you combine rebates with rooftop solar and smart controls such as timers or solar diversion, the payback period on a quality heat pump vs solar hot water setup can shrink to just a few years, with hundreds of dollars per year shaved off bills.
