Hot Water Rebates, Tariffs & Savings
There is growing interest in Caulfield Junction in replacing old gas or electric units with efficient options such as a heat pump hot water system, a modern electric hot water system or a solar hot water heating system. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that can trim the solar hot water price / cost or heat pump hot water price / cost by a substantial percentage. Victoria also offers state‑based support that can work alongside STCs for qualifying homes, and there are programs that operate like an electric hot water system rebate when you shift away from gas.
