Hot Water Rebates, Tariffs & Savings
Right across WA, and particularly in regional areas like The Plains, homeowners are replacing old gas or electric units with heat pumps, efficient electric hot water systems and solar hot water. Federal incentives such as Small‑scale Technology Certificates (STCs) reduce the upfront hot water system price by effectively acting as a discount at the point of sale. On top of that, state‑based support can operate like a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate, depending on the program and technology.
When you combine these incentives, it is common for the total heat pump hot water price or solar hot water price to drop by 20–40% compared with the sticker cost. That brings the real hot water system cost down to a much more manageable level. Factor in bill savings of a few hundred dollars a year and the payback period on a quality energy efficient hot water system can be surprisingly short, especially if you use timers or solar‑diversion to run the system when your PV is exporting. For many households, solar hot water vs electric hot water or heat pump vs solar hot water is less about which is “better” and more about which fits the roof space, budget and lifestyle.
If your current unit is more than 10 years old, running on gas, or you are unsure about your hot water rebate WA options, it is a good time to look at a hot water repair, solar hot water repair, or full solar hot water tank replacement. A well‑planned electric hot water installation or efficient heat pump hot water installation can lock in lower running costs for years.
If you live in The Plains and want to cut bills, reduce emissions and future‑proof your home, now is the time to check whether your place is ready for a hot water upgrade.
