Hot Water Rebates, Tariffs & Savings
Right now there is growing interest in hot water VIC upgrades that replace ageing gas or electric units with efficient options in Mcmillans. Homeowners can often tap into a mix of Australian Government Small‑scale Technology Certificates (STCs) and state incentives such as a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate.

With the right rebates, it is common for households to save hundreds of dollars a year on bills, and the payback period for a new heat pump or solar hot water system can shorten dramatically, especially if you already have solar and use timers or solar‑diversion to heat water during the day. When you factor in lower maintenance, fewer emergency hot water repair call‑outs and long warranties, an energy efficient hot water system quickly becomes a smart long‑term move.
