Homeowners in South Maitland can also take advantage of a range of hot water rebate nsw programs. At a federal level, Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump units, effectively cutting the upfront solar hot water price / cost or heat pump hot water price / cost. NSW state schemes can add a heat pump hot water rebate or solar hot water rebate on top, and there are also electric hot water system rebate offers in some programs when you replace old resistive units. Together, these incentives can reduce the system cost by a substantial percentage and shorten the payback period to just a few years, especially when paired with rooftop solar and smart timers or solar diversion controls.
Choosing between heat pump vs solar hot water, or weighing up solar hot water vs electric hot water, comes down to your roof space, budget, and how you use hot water. For some homes, a compact Sanden heat pump or Rheem solar hot water setup will be the best heat pump hot water system or best hot water system Australia‑wide for their needs.
