Hot Water Rebates, Tariffs & Savings
For Biarra homeowners, the hot water rebate QLD programs and Federal incentives can significantly reduce upfront costs. Eligible heat pump hot water and solar hot water installation projects can create Small‑scale Technology Certificates (STCs), which effectively discount the system price at the point of sale. On top of that, state‑based schemes may offer a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate when replacing old, inefficient gas units. These discounts can cut the effective heat pump hot water price or solar hot water price by a substantial percentage, and typical upgrades can shave hundreds of dollars per year off power bills. With smart tariffs, timers or solar diversion controls, a modern electric hot water installation can soak up excess solar and become a truly energy efficient hot water system.
