Hot water systems in Goulburn Island
On Goulburn Island, hot water is something you notice straight away when it is not working. With energy costs rising across the NT and many households running on older gas or electric units, more locals are looking at an energy efficient hot water system as their next upgrade.

Hot Water Rebates, Tariffs & Savings
For Goulburn Island homes and businesses, replacing old gas or tired electric units with a heat pump hot water system, efficient electric hot water system or solar hot water system is becoming more attractive every year. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that reduces the installed solar hot water price or heat pump hot water price.

With the right choice, Goulburn Island households can enjoy hundreds of dollars per year in savings, while also cutting emissions.
