Hot Water Rebates, Tariffs & Savings
Whether you are replacing a failed unit or planning ahead, there is growing interest in Little Hartley in moving from gas or ageing cylinders to an energy efficient hot water system. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water installation projects and effectively lower the upfront hot water system price / cost at the point of sale. On top of this, NSW programmes can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when you replace an older, inefficient model.
These hot water rebate NSW schemes can reduce the heat pump hot water price / cost or solar hot water price / cost by a substantial percentage, often cutting payback periods to just a few years, especially if you already have rooftop solar. Using timers or solar diversion to run a heat pump when your PV is generating can turn it into a truly energy efficient hot water system, helping you get closer to a low‑bill, all‑electric home.
If your current unit is more than 10–15 years old, needs regular hot water repair, or you are facing a solar hot water tank replacement, it is a good time to compare heat pump vs solar hot water and modern electric options.
