Hot Water Rebates, Tariffs & Savings
For hot water NSW homeowners in Toonumbar, there is growing interest in replacing old gas or electric units with heat pumps, modern electric hot water system options and solar hot water systems. Federal incentives such as Small-scale Technology Certificates (STCs) apply to eligible solar hot water heating system and heat pump hot water system installs, effectively working as an upfront discount. On top of that, state-based hot water rebate NSW programs can provide a solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate when you are moving away from inefficient older units.
These incentives can cut the heat pump hot water price or cost and solar hot water price or cost by a substantial percentage, sometimes trimming thousands off the upfront hot water system price or cost. When you add bill savings of a few hundred dollars a year, the payback period for an energy efficient hot water system can be surprisingly short, especially if you use timers or solar diversion so your electric hot water system heats mainly on cheap or solar power. For many locals, that makes an efficient hot water upgrade one of the smartest home improvements they can make.
