Hot Water Rebates, Tariffs & Savings
For Doyles Creek homeowners, the appeal of replacing old gas or electric hot water with an energy efficient hot water system keeps growing as electricity prices shift and gas becomes less attractive. Federal incentives such as Small‑scale Technology Certificates (STCs) can lower the solar hot water price / cost or heat pump hot water price / cost at the point of sale, while NSW hot water rebate schemes and occasional electric hot water system rebate offers further trim upfront costs. When you stack a solar hot water rebate or heat pump hot water rebate on top of STCs, it is common to see the effective hot water system price / cost cut by a substantial percentage, with payback periods dropping to just a few years, especially if you already have rooftop solar. Using timers or smart controls to line up your system with daytime solar can boost savings even more.
Whether you are weighing up electric hot water vs gas hot water, comparing heat pump vs solar hot water, or simply need hot water repair or solar hot water repair and solar hot water tank replacement, it pays to look closely at long‑term running costs. In many cases, a well‑sized Rheem solar hot water, Rinnai solar hot water, Sanden heat pump or similar best heat pump hot water system will beat a basic replacement on lifetime cost.
