Hot Water Rebates, Tariffs & Savings
Right now there is growing interest in Killarney in replacing tired gas or electric units with a more efficient hot water system – whether that is a heat pump, a solar hot water system or a modern, well‑controlled electric hot water system. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount. On top of that, Victorian programmes can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when you move away from gas. Together, these can cut the apparent hot water system price or cost by a substantial margin and shorten the payback period to just a few years. When you combine rebates with rooftop solar, smart tariffs, timers or solar‑diversion controls, you can drive the heat pump hot water price or cost of ownership down even further and get close to the most efficient hot water system possible for your home.
If you are weighing up heat pump vs solar hot water, or solar hot water vs electric hot water, it is worth getting tailored advice on hot water VIC tariffs, hot water rebate VIC options and which energy efficient hot water system suits your roof, budget and usage.
