Hot Water Rebates, Tariffs & Savings
Whether you are considering a heat pump hot water system, a solar hot water heating system or a more efficient electric hot water system, there is growing interest in Grassmere in replacing ageing gas or resistive electric units. Federal incentives like Small‑scale Technology Certificates (STCs) can reduce the upfront solar hot water price / cost or heat pump hot water price / cost by hundreds of dollars at the point of sale. On top of that, the Victorian hot water rebate VIC programs can provide a solar hot water rebate or heat pump hot water rebate, and in some cases an electric hot water system rebate, cutting the effective system cost by a significant percentage.
For Grassmere households, that means you can often upgrade to an energy efficient hot water system with a payback period of only a few years, especially if you already have rooftop solar. Using timers or smart controls to run a heat pump during the middle of the day, or using solar‑diversion to an electric hot water system, can squeeze even more value from your solar. When you compare electric hot water vs gas hot water on long‑term cost and emissions, going efficient electric usually wins.
