Hot Water Rebates, Tariffs & Savings
Right now, more Woronora households are looking at replacing tired gas or electric units with efficient options like a heat pump hot water system, a modern electric hot water system or a solar hot water system that uses the sun instead of expensive grid power. A key driver is the range of Australian Government incentives and hot water rebate NSW programs available. Small‑scale Technology Certificates (STCs) effectively act as a national solar hot water rebate or heat pump hot water rebate, cutting the upfront solar hot water price / cost or heat pump hot water price / cost. On top of that, state‑based schemes can provide extra discounts for eligible homes, and in some cases an electric hot water system rebate for shifting off gas.
For many Woronora families, these rebates can reduce the installed hot water system price / cost by a substantial percentage, turning a big capital purchase into a much more manageable upgrade. Combine that with hundreds of dollars per year in bill savings and the payback period on a quality solar hot water heating system or heat pump can shrink to just a few years, especially if you already have rooftop solar. Using timers or solar‑diversion controls to run your electric hot water installation or heat pump when your panels are producing can squeeze even more value from your system. That is also where options like solar hot water vs electric hot water, or electric hot water vs gas hot water, really start to favour efficient all‑electric homes.
