Hot Water Rebates, Tariffs & Savings
For Tocal households, hot water nsw incentives are helping to tip the balance towards efficient options. Even if you are just replacing a like‑for‑like electric hot water system, there may be an electric hot water system rebate available when you step up to an energy efficient hot water system. Federal Small‑scale Technology Certificates (STCs) reduce the effective hot water system price / cost for approved systems like heat pumps and solar hot water, and NSW schemes can add a specific heat pump hot water rebate or solar hot water rebate on top. These discounts can cut the upfront heat pump hot water price / cost or solar hot water price / cost by a significant percentage, often bringing premium systems like a Sanden heat pump or quality Rheem solar hot water into reach. Combined with typical savings of hundreds of dollars a year on bills, payback periods can be shortened further by using timers, smart controls or solar‑diversion so your electric hot water system runs when rooftop solar is producing. For many locals, a well‑designed hot water nsw upgrade is one of the quickest ways to trim energy bills.
