Hot Water Rebates, Tariffs & Savings
Across East Coraki, there is growing interest in replacing old gas or electric hot water with efficient options such as a heat pump hot water system, a new electric hot water system paired with solar, or a roof‑mounted solar hot water heating system. Australian Federal Government incentives, like Small‑scale Technology Certificates (STCs), can reduce the effective heat pump hot water price or solar hot water price at the point of sale. On top of that, state‑based schemes in NSW can provide a heat pump hot water rebate or solar hot water rebate for eligible homes, and in some cases an electric hot water system rebate when replacing inefficient units. These hot water rebate NSW programs can cut the upfront hot water system cost by a significant percentage, bringing options like Rheem solar hot water, Rinnai solar hot water or a premium Sanden heat pump within reach.
When you combine rebates with smart tariffs and rooftop solar, payback periods can shorten dramatically.
