Hot Water Rebates, Tariffs & Savings
For Hawkesbury Heights homeowners, there is growing interest in replacing old gas or electric hot water with efficient options such as a heat pump hot water system, a modern 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 discounting the solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, NSW hot water rebate programs can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when you move away from gas.
In practice, these hot water rebate NSW incentives can knock a substantial percentage off the upfront hot water system price / cost, especially when combined with retailer discounts. That means payback periods can drop to just a few years, particularly if you use timers or solar diversion so your electric hot water installation runs mostly on your own solar. Many households see hundreds of dollars per year off their bills with an energy efficient hot water system, especially when they choose leading brands such as Rheem heat pump hot water, Sanden heat pump or Rinnai solar hot water. Experienced local installers can also advise on tariffs, solar hot water repair, general hot water repair, and when it makes sense to choose electric hot water vs gas hot water for your home.
