Replacing a tired gas storage unit with an energy efficient hot water system can deliver substantial annual hot water energy savings for Sumner homeowners, especially when paired with rooftop solar.
In the 4074 postcode, most residents live in separate houses, with a lot of three and four bedroom homes, so hot water demand is steady all year.

Hot Water Rebates, Tariffs & Savings
Right now, more Sumner households are looking to move away from gas and older resistive units towards efficient options like a new heat pump hot water installation, solar hot water installation or a smarter electric hot water installation that runs on daytime solar. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pumps, effectively acting as a solar hot water rebate or heat pump hot water rebate that comes off the upfront hot water system price or cost. Queensland programs can also operate as an electric hot water system rebate or targeted hot water rebate QLD homeowners can access, depending on eligibility.
When you combine these discounts with off‑peak tariffs and rooftop solar, you can slice the heat pump hot water price or cost or the solar hot water price or cost by a significant percentage, and often cut payback periods to just a few years. Using timers or solar diversion controls to run your hot water system when the sun is shining can add hundreds of dollars a year in extra savings.
