Hot Water Rebates, Tariffs & Savings
Right across Greenhill, more households are weighing up heat pump vs solar hot water, or comparing solar hot water vs electric hot water and even electric hot water vs gas hot water as old units fail. Federal incentives such as Small‑scale Technology Certificates (STCs) help cut the solar hot water price / cost and heat pump hot water price / cost, while NSW schemes can add a heat pump hot water rebate or solar hot water rebate for eligible homes. In some cases, these hot water rebate NSW programs can reduce the system cost by a substantial percentage, especially when combined with retailer discounts. There are also electric hot water system rebate offers from time to time, which can make a modern electric hot water system far more attractive than sticking with gas. When you factor in typical savings of a few hundred dollars per year and use timers or solar‑diversion to run your hot water system when your solar is producing, the payback period for a quality heat pump hot water installation or solar hot water tank replacement can be surprisingly short.
