Hot Water Rebates, Tariffs & Savings
Right across Hardy there is growing interest in replacing older gas or resistive electric units with options like a heat pump hot water system, a new electric hot water system designed to work with solar, or a roof‑mounted solar hot water heating system. Australian Government incentives, such as Small‑scale Technology Certificates (STCs), can reduce the solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of this, South Australian hot water rebate SA programs can offer a heat pump hot water rebate or solar hot water rebate that cuts the upfront solar hot water price / cost by a substantial percentage.
For many Hardy homes, these incentives mean the effective hot water system price / cost is much lower than expected, with payback periods often dropping to just a few years. When you combine rebates with off‑peak tariffs, timers, or solar diversion that sends excess rooftop solar into your electric hot water system, the result can be hundreds of dollars per year off bills. Choosing an energy efficient hot water system is also a smart move if you are planning an all‑electric home or comparing solar hot water vs electric hot water and electric hot water vs gas hot water for long‑term savings.
