Hot Water Rebates, Tariffs & Savings
For Kings Park households, the big shift now is replacing old gas or off-peak electric units with efficient options like heat pumps, newer electric hot water systems or a solar hot water heating system. Federal incentives such as Small-scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively working like an upfront discount. On top of that, South Australian hot water rebate programs can support heat pump hot water installation and sometimes solar hot water installation as well, significantly lowering the heat pump hot water price or solar hot water price paid out-of-pocket.
Depending on the system and installer, these incentives can knock a substantial percentage off the hot water system cost, and an electric hot water system rebate may also apply when you are shifting away from gas. With typical savings of hundreds of dollars per year, many Kings Park homes see payback periods shrink even further when they combine rebates with rooftop solar and smart controls like timers or solar diversion. That way, your energy efficient hot water system runs mainly on your own surplus solar instead of expensive grid power.
