Hot Water Rebates, Tariffs & Savings
With many Bunbury households still on older gas or resistive electric units, there is strong demand for hot water repair, hot water replacement and full hot water upgrade projects. When a system fails, locals are now weighing heat pump vs solar hot water, or solar hot water vs electric hot water, instead of simply swapping like‑for‑like. Federal incentives through Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively acting like an upfront discount off the solar hot water price / cost or heat pump hot water price / cost. On top of that, WA programs and retailer offers can operate like a hot water rebate wa, including heat pump hot water rebate and solar hot water rebate options that further reduce the installed hot water system price.
When you combine these incentives with smart tariffs and timers, the numbers get even better. An electric hot water system rebate or state heat pump support can cut the upfront solar hot water price / cost or heat pump hot water price / cost by a substantial percentage. Many Bunbury homes see hundreds of dollars a year off bills, and payback periods can shorten significantly when a heat pump hot water system runs mostly on rooftop solar. Using timers or solar‑diversion controls to run your electric hot water installation or heat pump during the middle of the day increases self‑consumption and turns your hot water tank into a thermal battery.
Whether you need hot water repair, solar hot water repair, solar hot water tank replacement or a fresh hot water installation, it pays to look beyond the sticker price and think about lifetime costs. Comparing electric hot water vs gas hot water, solar hot water vs electric hot water, and the different hot water system price ranges with available hot water rebate wa options will help you choose the right fit for your home.
