Hot Water Rebates, Tariffs & Savings
Right now, more Darley homeowners are replacing old gas or electric hot water with efficient options such as a heat pump hot water system, a newer electric hot water system or a solar hot water system. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount off the hot water system price or cost.

For Darley households, these solar hot water rebate and heat pump hot water rebate schemes can cut the heat pump hot water price or cost, or the solar hot water price or cost, by a substantial percentage. Combined with typical bill savings of hundreds of dollars a year, payback periods can be slashed, especially if you use timers or solar‑diversion to run your most efficient hot water system when your rooftop solar is generating. That means your hot water VIC upgrade not only reduces bills but also lowers emissions, particularly when you compare electric hot water vs gas hot water or solar hot water vs electric hot water on grid power.
If your current unit is leaking, unreliable or more than 10 years old, it may be time to compare heat pump vs solar hot water, look at the best heat pump hot water system for your needs, or consider a quality rheem solar hot water or rinnai solar hot water setup.
