Hot Water Rebates, Tariffs & Savings
There is growing interest in Cobaw in replacing old gas or tired electric units with efficient options such as a heat pump hot water system, a newer electric hot water system, or a full solar hot water heating system. A key reason is the range of incentives on offer. Australian Federal Government small‑scale technology certificates (STCs) effectively act as a solar hot water rebate or heat pump hot water rebate, lowering the upfront hot water system price or cost at the point of sale. Victoria also offers additional state‑based support that can act like a hot water rebate vic for eligible efficient systems, including some electric hot water system rebate programs.
With these incentives, the effective heat pump hot water price or cost or solar hot water price or cost can be cut by a substantial percentage, often shaving many hundreds off the initial outlay. Combine that with typical bill reductions of a few hundred dollars per year and the payback period can be surprisingly short, especially if you run your energy efficient hot water system on off‑peak tariffs or use timers and solar diversion to soak up excess rooftop solar. For many Cobaw homes, that makes an efficient hot water upgrade one of the simplest ways to future‑proof the property.
