Central Coast NSW ESS Rebates and Waterfront Salt Air

The NSW Energy Savings Scheme (ESS) provides point-of-sale rebates for heat pump hot water systems on the Central Coast, reducing installed cost by $300-$1,000. Central Coast lakeside and coastal properties (Gosford waterfront, Long Jetty, The Entrance, Terrigal) require salt air-resistant materials for outdoor hot water components, stainless steel fittings and corrosion-rated heat pump enclosures. Central Coast homeowners with rooftop solar can maximise their investment by pairing a heat pump hot water system with a solar timer, running the system during peak generation hours to use free solar energy rather than drawing from the grid.
