Hot Water Rebates, Tariffs & Savings
Right now, more Minnamurra households are weighing up solar hot water vs electric hot water, or electric hot water vs gas hot water, and using rebates to bring the hot water system price down. Federal Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, acting like an upfront discount. On top of that, NSW hot water rebate programs can support a heat pump hot water rebate, solar hot water rebate, or even an electric hot water system rebate in some schemes, especially when replacing old, inefficient units.
These incentives can trim the heat pump hot water price or solar hot water price by a substantial percentage, often cutting payback periods to just a few years. Many Minnamurra homes also use timers or solar‑diversion controls so their electric hot water installation or all‑electric heat pump runs mostly on rooftop solar, squeezing even more savings from every sunny day. With the right tariff and a quality system from brands like Sanden, Rheem or Rinnai, it is possible to run one of the best heat pump hot water system options on the market for a fraction of the cost of gas.
