In many cases, these combined incentives can knock a substantial percentage off the hot water system price, trimming payback periods to just a few years, especially if you already have rooftop solar.
Depending on your setup, a heat pump hot water rebate or solar hot water rebate can mean the installed heat pump hot water cost is comparable to a basic replacement gas unit, but with much lower ongoing bills. For some households, an electric hot water system rebate may also apply to encourage a switch away from gas. Once installed, using timers, smart controls or solar diversion to run your hot water system when your panels are producing can boost savings even further. When you compare heat pump vs solar hot water or solar hot water vs electric hot water, the right choice often comes down to roof space, budget, tariff options and how much of your own solar you can use.
