Hot Water Rebates, Tariffs & Savings
Right now, there is strong interest in Coombadjha in replacing old gas or tired electric units with efficient options such as heat pump hot water, newer electric hot water system models or a roof‑mounted solar hot water system. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount on the hot water system price. On top of that, New South Wales programs can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate, for swapping out old, inefficient units. Together, these hot water rebate nsw schemes can cut the heat pump hot water price or solar hot water price by a substantial percentage, often trimming thousands off the hot water system cost for larger households.
For many Coombadjha homes, typical savings from an efficient hot water upgrade are in the hundreds of dollars per year, with payback periods shortened even further if you already have rooftop solar.
