Hot Water Rebates, Tariffs & Savings
For Cornalla households, there is growing interest in replacing old gas or electric units with a heat pump hot water system, a newer electric hot water system or a solar hot water system that works with existing PV. Federal incentives such as Small-scale Technology Certificates (STCs) can cut the upfront solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, NSW hot water rebate programs can provide a heat pump hot water rebate or solar hot water rebate for eligible homes, and in some cases an electric hot water system rebate for efficient models.
These hot water rebate NSW offers can effectively reduce the system cost by a substantial percentage, often turning a multi‑year payback into just a few years, especially when you run the system on solar or off‑peak tariffs. Many Cornalla homeowners are also using timers or solar diversion controllers so their hot water system runs when rooftop solar is strongest, further cutting bills. With the right setup, the solar hot water price / cost or heat pump hot water price / cost can be more than offset over time by hundreds of dollars a year in savings.
