Hot Water Rebates, Tariffs & Savings
Homeowners in Higher Macdonald are increasingly replacing old gas or electric units with efficient heat pump hot water or solar hot water systems, and sometimes a new electric hot water system that works hand‑in‑hand with rooftop solar. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pumps, reducing the effective solar hot water price / cost and heat pump hot water price / cost at the point of sale. New South Wales schemes can also provide a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate, particularly when you are moving away from gas.
When you stack these hot water rebate NSW offers with STCs, it is common for discounts to effectively cut the upfront hot water system price / cost by 20–40% for qualifying homes. That brings the solar hot water price / cost or heat pump hot water price / cost much closer to a basic electric unit, while ongoing savings can be hundreds of dollars a year. Payback periods often drop to just a few years, especially if you use timers or solar diversion to run your system when the sun is out. For many households, that makes an energy efficient hot water system the best heat pump hot water system or solar option they will buy for the next decade.
Whether you need hot water repair, solar hot water repair, solar hot water tank replacement or a full electric hot water installation, it pays to plan ahead.
