Hot Water Rebates, Tariffs & Savings

For Williams Raaf homeowners, hot water rebate vic programs and federal incentives make upgrading far more affordable. The Australian Government’s Small‑scale Technology Certificates (STCs) effectively discount the upfront solar hot water price / cost and heat pump hot water price / cost. On top of that, Victoria offers a heat pump hot water rebate or solar hot water rebate for eligible households, and in some cases an electric hot water system rebate when replacing old, inefficient units. These discounts can reduce the system cost by a substantial percentage and cut payback periods to just a few years, especially if you also have rooftop solar and use timers or solar diversion to run your system when the sun is out.

Switching from electric hot water vs gas hot water to a modern heat pump or solar hot water system can easily save hundreds of dollars a year, while a smart electric hot water system running on solar can rival the best hot water system Australia has to offer. If your existing solar hot water tank replacement is due, it can be the perfect time to compare solar hot water price / cost with a new Sanden heat pump or Rheem heat pump hot water unit and decide which option will be the most efficient hot water system for your household.
