Hot Water Rebates, Tariffs & Savings
Whether you are comparing heat pump vs solar hot water or weighing up solar hot water vs electric hot water, Gosford homeowners are increasingly replacing old units with efficient options. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate. NSW programmes and occasional retailer offers can further reduce the heat pump hot water price or solar hot water price, and there are also electric hot water system rebate schemes at times when governments want to encourage fuel‑switching away from gas hot water.
With the right combination of rebates, it is common for discounts to shave 20–40% off the hot water system price or cost. That shortens payback periods, especially if you also have rooftop solar and use timers or smart controls to heat water during the day. For many Gosford households, a quality energy efficient hot water system can cut hundreds of dollars a year from bills and significantly reduce emissions.
