Hot Water Rebates, Tariffs & Savings

For Preston homeowners, the financial case for upgrading is boosted by hot water rebate QLD programs and Federal incentives. The Australian Government’s Small-scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively reducing the solar hot water price / cost or heat pump hot water price / cost at the point of sale. Queensland schemes can also provide a heat pump hot water rebate, solar hot water rebate and, at times, an electric hot water system rebate when you replace old, inefficient units. These discounts can cut the upfront hot water system price / cost by a substantial percentage, often shaving years off the payback period. Combine that with rooftop solar, a smart timer or solar diversion, and many Preston households see hundreds of dollars per year in savings. When you compare electric hot water vs gas hot water under modern tariffs, efficient electric options paired with solar often come out ahead.
