Hot Water Rebates, Tariffs & Savings
Lilli Pilli homeowners are increasingly replacing old gas or resistive electric hot water with efficient options like a heat pump hot water system, a modern electric hot water system or a roof mounted solar hot water system. Federal incentives like Small scale Technology Certificates (STCs) reduce the effective heat pump hot water price or solar hot water price at the point of sale, and NSW hot water rebate programs can further cut the upfront hot water system cost. Depending on the system, these discounts and hot water rebate NSW offers can trim the price by a substantial percentage, often bringing payback periods down to just a few years, especially if you already have rooftop solar. Pairing a heat pump or electric hot water installation with timers or solar diversion controls lets you heat water when your panels are producing, boosting savings and making the system one of the most efficient hot water system choices available. There are also electric hot water system rebate options in some schemes that encourage households to move from gas to electric hot water vs gas hot water, and to choose solar hot water vs electric hot water where roof space and orientation suit.
