Hot Water Rebates, Tariffs & Savings
In Slacks Creek, the combination of strong sun and rising energy prices is pushing more people to compare heat pump vs solar hot water and even solar hot water vs electric hot water to see what stacks up best for their property. The Australian Government’s Small-scale Technology Certificates (STCs) effectively act as an upfront solar hot water rebate or heat pump hot water rebate, cutting the installed solar hot water price / cost or heat pump hot water price / cost by a significant margin. On top of that, Queensland hot water rebate programs and occasional electric hot water system rebate offers can further trim the hot water system price / cost for eligible households.
For many Slacks Creek homes, these incentives can reduce the system cost by 20–40%, and when combined with rooftop solar and smart tariffs, payback periods can drop to just a few years. Switching from electric hot water vs gas hot water to an efficient heat pump or solar hot water vs electric hot water can easily save hundreds of dollars a year, especially if you use timers or solar diversion to run your system during sunny periods. With the right setup, a modern electric hot water installation powered by solar can be an excellent energy efficient hot water system choice alongside traditional solar hot water.
