Hot Water Rebates, Tariffs & Savings
Around Manuka, there is growing interest in replacing ageing gas or electric units with a heat pump hot water system, a new solar hot water heating system or a high-efficiency electric hot water system. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that can trim system cost by a significant percentage. In the ACT, additional state-based schemes and electric hot water system rebate programs may also apply, helping to bring the heat pump hot water price / cost or solar hot water price / cost much closer to a like-for-like gas replacement.
For many Manuka homes, combining rebates with rooftop solar can cut payback periods dramatically, often to well under 10 years and sometimes just a few years for high-usage households. Using timers or smart controls to run a heat pump during solar hours turns it into a truly energy efficient hot water system. When you factor in lower hot water system price / cost over the life of the unit, ongoing hot water repair savings, and the ability to move towards an all-electric home, it is easy to see why hot water ACT upgrades are gaining momentum. Local hot water rebate ACT options make it even more appealing.
If your existing unit is older, noisy or struggling to keep up, now is a smart time to check whether your Manuka home is ready for a hot water upgrade.
