Hot Water Rebates, Tariffs & Savings
All of this interest is being helped along by generous hot water rebate NT options. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible heat pump hot water and solar hot water systems, while state-based programs can offer a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate in some circumstances. These incentives can slice a substantial percentage off the upfront hot water system price / cost, heat pump hot water price / cost or solar hot water price / cost, making upgrades far more affordable for Sanderson households.
For many homes, shifting from electric hot water vs gas hot water to a modern heat pump or solar setup can trim hundreds of dollars a year off bills. When you combine rebates with rooftop solar, timers or solar diversion controls, the payback period on a new system can shorten dramatically. For landlords with rentals or families looking to future-proof, that is a compelling reason to look at a hot water installation or hot water repair sooner rather than later.
