Hot Water Rebates, Tariffs & Savings
Right across Alexandra there is growing interest in replacing old gas or resistive electric units with efficient options like heat pump hot water, modern electric hot water systems or a well‑sized solar hot water heating system. Homeowners can often tap into Australian Government Small‑scale Technology Certificates (STCs), which effectively act as an upfront discount on eligible systems. On top of that, state‑based programs in Victoria can provide a solar hot water rebate or a heat pump hot water rebate, and in some cases an electric hot water system rebate when moving away from gas. Together, these incentives can substantially reduce the solar hot water price or heat pump hot water cost, sometimes cutting the upfront outlay by a significant percentage. When you combine rebates, smart tariffs and rooftop solar, payback periods can shrink to just a few years, with many Alexandra homes saving hundreds of dollars a year. Adding timers or solar‑diversion controls so your system heats mainly during sunny hours can further boost savings and help deliver the best heat pump hot water system outcome for your property.
