Hot Water Rebates, Tariffs & Savings
For Grange households, hot water rebates are an important part of the equation. Many residents are replacing old gas or resistive electric units with a heat pump hot water system, a high‑efficiency electric hot water system or a rooftop solar hot water heating system.

On top of that, state‑based schemes can offer a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate that further cuts the upfront hot water system cost.
For a typical family in Grange, these hot water rebate QLD programs can trim the installed cost by a substantial percentage and shorten payback to just a few years, especially when combined with rooftop solar. Many locals also use timers or solar‑diversion controls so their hot water system runs when the sun is shining, squeezing even more value from their panels. Over the life of the system, that can mean thousands of dollars in savings compared with old electric hot water vs gas hot water options.
