Hot water rebates, tariffs & savings
Interest in hot water VIC upgrades is being driven by rising gas prices and the push towards all‑electric homes. Many Milloo households are looking at replacing old gas or electric units with heat pump hot water installation, solar hot water installation or efficient electric hot water installation paired with rooftop solar. The Australian Government’s Small‑scale Technology Certificates (STCs) effectively act as a solar hot water rebate or heat pump hot water rebate, reducing the upfront solar hot water price / cost and heat pump hot water price / cost. Victoria also offers state‑based hot water rebate VIC programs from time to time, plus electric hot water system rebate schemes that further cut the hot water system price / cost for eligible homes.
When you combine these incentives, discounts can slice a substantial percentage off the installed solar hot water price / cost or heat pump hot water price / cost, often bringing payback down to just a few years. Many Milloo households then use timers or solar‑diversion controls so their energy efficient hot water system runs when their solar is generating, further boosting savings. Over the life of the unit, that can add up to thousands of dollars saved and much lower emissions compared with electric hot water vs gas hot water.
