Hot Water Rebates, Tariffs & Savings
For Payneham South homeowners, there is growing interest in replacing old gas or electric units with efficient heat pump hot water installation, solar hot water installation or smarter electric hot water installation that works with rooftop solar. Federal incentives through Small-scale Technology Certificates (STCs) effectively discount the upfront hot water system price / cost for eligible systems, including Rheem heat pump hot water, Sanden heat pump units and selected solar brands. On top of that, South Australians may be able to access state-based heat pump hot water rebate or solar hot water rebate programs from time to time, as well as an electric hot water system rebate when moving away from gas.
These hot water rebate SA incentives can trim the heat pump hot water price / cost or solar hot water price / cost by a substantial percentage, cutting payback periods to just a few years in some cases. When you combine rebates, off-peak or flexible tariffs, and solar-diversion or timers to run your energy efficient hot water system during sunny hours, you can further reduce your bills. For many Payneham South households, solar hot water vs electric hot water is no longer a simple either/or choice – pairing a quality system with smart controls delivers the most efficient hot water system and long-term savings.
