When comparing heat pump hot water price / cost and solar hot water price / cost with a straightforward electric hot water system price / cost, it is important to factor in rebates, running costs and lifespan – not just the sticker price.
Hot Water Rebates, Tariffs & Savings
Around Groomsville there is growing interest in replacing old gas or electric hot water with efficient options like heat pumps, modern electric hot water and solar hot water. Federal incentives, such as Small‑scale Technology Certificates (STCs), can reduce the upfront solar hot water price / cost or heat pump hot water price / cost, and Queensland hot water rebate QLD programs sometimes add extra support for eligible heat pump hot water installation or solar hot water installation. There are also electric hot water system rebate offers from time to time, particularly when moving away from gas.
These solar hot water rebate and heat pump hot water rebate schemes can effectively knock a substantial percentage off the installed cost, shortening payback periods to just a few years in some cases. Combine rebates with good tariffs, timers or solar diversion to match hot water heating to your rooftop solar, and you can squeeze even more value from an energy efficient hot water system.
