Hot Water Rebates, Tariffs & Savings

Right across Black Rock, more households are now considering replacing old gas or resistive electric hot water with a heat pump hot water system, a high‑efficiency electric hot water system or a solar hot water heating system. For many, the key questions are hot water system price, heat pump hot water price and solar hot water price – and how rebates can bring those costs down.

Black Rock homeowners can usually access Federal Small‑scale Technology Certificates (STCs) for eligible systems, which act like a solar hot water rebate or heat pump hot water rebate by reducing the upfront hot water system cost at the point of sale. South Australia also offers state‑based incentives from time to time, including electric hot water system rebate programs that support moving away from gas. When you stack these hot water rebate SA options together, it is common to see the effective system cost reduced by 20–40%, and payback periods shortened to just a few years, especially if you already have rooftop solar.

Once installed, an energy efficient hot water system can trim hundreds of dollars a year from your power bills. Using timers or solar‑diversion controls to run your electric hot water vs gas hot water at the right time of day can boost savings even further, particularly when you are comparing solar hot water vs electric hot water on long‑term running costs. If you already have a solar hot water system, a timely solar hot water tank replacement or solar hot water repair can also restore performance and extend system life.
