Hot Water Rebates, Tariffs & Savings
Right across Cape Woolamai there is growing interest in replacing old gas or electric hot water with efficient options such as a heat pump hot water system, modern electric hot water system or solar hot water heating system. Homeowners can usually tap into a mix of Australian Government Small-scale Technology Certificates (STCs) and state-based heat pump hot water rebate or solar hot water rebate schemes, plus an electric hot water system rebate in some cases. For many hot water VIC households, these incentives can effectively knock a substantial percentage off the upfront heat pump hot water price or cost or solar hot water price or cost, bringing quality systems like Sanden heat pump or Rheem solar hot water within reach.
When you combine rebates with off-peak tariffs, timers or solar-diversion controls, it is common to see hundreds of dollars a year shaved off bills and payback periods dropping to just a few years. Smart controls can ensure your hot water system runs mainly when your rooftop solar is generating, making your hot water repair or upgrade work even harder for your wallet. For some families, this is the final piece in going all electric and moving away from electric hot water vs gas hot water debates altogether.
