Hot Water Rebates, Tariffs & Savings
All this interest in hot water WA wide is helped by generous incentives. For Kiara homeowners, Australian Government Small‑scale Technology Certificates (STCs) effectively act as an upfront discount on approved solar hot water systems, heat pump hot water systems and some efficient electric hot water options. On top of that, state‑based schemes can provide a solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate in certain programs, bringing down the hot water system cost by a substantial percentage.
When you combine rebates with a well‑sized solar PV system, payback periods for an energy efficient hot water system can drop to just a few years. Many locals use timers or solar diversion so their hot water is heated when the sun is shining and grid tariffs are low, squeezing even more out of their investment. It is also worth checking hot water rebate WA programs from time to time, as offers and eligibility can change.
