Hot Water Rebates, Tariffs & Savings
Right now there is growing interest in Oyster Cove in replacing old gas or electric hot water with efficient options like heat pumps, modern electric hot water system upgrades and solar hot water. Homeowners can often tap into a mix of Australian Government Small-scale Technology Certificates (STCs) and state-based schemes such as a heat pump hot water rebate or solar hot water rebate, plus an electric hot water system rebate in some programs. These incentives can reduce the upfront hot water system price by a substantial percentage, especially when you choose a qualifying heat pump or solar hot water system.
When you factor in rebates, the effective heat pump hot water price or solar hot water price can drop enough that payback periods shrink to just a few years, particularly if you already have rooftop solar. Using timers or solar diversion to run a heat pump during the middle of the day can turn your system into one of the most efficient hot water system choices available, cutting bills by hundreds of dollars per year. Even if you stay with an electric hot water installation, pairing it with solar and a smart tariff can still deliver meaningful savings.
If your current unit is leaking, unreliable, or more than 10 years old, it is worth comparing heat pump vs solar hot water and even solar hot water vs electric hot water to see what suits your household. A professional hot water installation can include everything from electric hot water installation to heat pump hot water installation, solar hot water tank replacement, and ongoing hot water repair or solar hot water repair to keep things running smoothly.
