Hot Water Rebates, Tariffs & Savings
For hot water SA homeowners, rebates are a big part of the story. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively acting as an upfront discount. On top of that, state programs can provide a solar hot water rebate or heat pump hot water rebate that further reduces the hot water system price or cost. In some cases, the combined incentives can knock a substantial percentage off the heat pump hot water price or cost, bringing a premium Sanden heat pump or similar unit within reach.
There are also incentives and tariff options that make electric hot water vs gas hot water more attractive. An electric hot water system rebate can help cover part of the electric hot water installation cost when you replace an old gas unit with an energy efficient hot water system. When you pair a modern electric or solar hot water vs electric hot water on standard tariffs with rooftop solar and a timer, you can heat water when the sun is shining and cut the solar hot water price or cost payback time significantly.
If your current unit is leaking, unreliable or just old and expensive to run, it is a good time to look at hot water repair or full hot water installation in Nantawarra.
