Hot Water Rebates, Tariffs & Savings
With energy prices rising, many Hindmarsh Island households are now reassessing electric hot water vs gas hot water and choosing efficient options like heat pumps, modern electric units or a solar hot water system. Australian Government Small‑scale Technology Certificates (STCs) apply to approved systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that cuts the hot water system price. South Australians can also access state‑based incentives that further reduce heat pump hot water price and solar hot water price, and in some cases there is an electric hot water system rebate for replacing old, inefficient units.
When you combine rebates with off‑peak tariffs or solar‑diversion controls, the payback period on an efficient hot water upgrade can drop to just a few years, with many homes saving hundreds of dollars a year. Smart timers that run a heat pump during the middle of the day, when your panels are pumping out power, are a simple way to turn your system into a truly energy efficient hot water system.
If your current hot water system is more than 10 years old, noisy, or you are often running out of hot water, it is a good time to explore options.
