If you have good roof space and strong sun, a rheem solar hot water or rinnai solar hot water setup, or even a chromagen solar hot water system, can deliver long‑term savings. For homes that just need a straightforward electric hot water installation, a modern, well‑insulated tank paired with rooftop solar can still be a very energy efficient hot water system.

When it comes to hot water WA homeowners can rely on, rebates and incentives make a big difference. Australian Government Small‑scale Technology Certificates (STCs) reduce the upfront solar hot water price / cost and heat pump hot water price / cost, effectively acting as a solar hot water rebate or heat pump hot water rebate at the point of sale. Western Australian programmes and retailer offers can also operate like a hot water rebate WA, and some households may access an electric hot water system rebate when replacing very old units. These discounts can shave a substantial percentage off the total hot water system price / cost, and when you combine that with hundreds of dollars a year off power bills, the payback period for a heat pump vs solar hot water upgrade can shorten to just a few years. Add smart controls, timers or solar diversion, and a solar hot water vs electric hot water comparison often comes out clearly in favour of efficient options.
