Hot Water Rebates, Tariffs & Savings
Across Windsor Gardens, more residents are now considering whether an energy efficient hot water system could replace an older gas or electric unit. The combination of federal and SA hot water rebate programs makes options like a solar hot water system, heat pump hot water system or efficient electric hot water system far more affordable.
At the federal level, Small-scale Technology Certificates (STCs) effectively act as an upfront discount on eligible systems, including many solar hot water heating system models and heat pumps.

Some newer all-electric units may also qualify for an electric hot water system rebate when they replace gas.
For Windsor Gardens homeowners, these combined incentives can reduce the system cost by a substantial percentage, trimming payback periods to just a few years, especially when paired with existing rooftop solar. Add simple measures like timers or solar diversion – running your electric or heat pump hot water during the middle of the day – and you can turn an already energy efficient hot water system into the most efficient hot water system for your home’s pattern of use. That is where solar hot water vs electric hot water, or electric hot water vs gas hot water, really tips in favour of modern, efficient technology.
