These hot water rebate VIC offers can effectively cut the upfront hot water system price / cost by a significant percentage, and when you combine rebates with off‑peak tariffs, timers or solar diversion, payback periods can drop to just a few years. Many Greensborough households see hundreds of dollars a year in savings, especially when upgrading from gas to a high‑performance system that would rank among the best heat pump hot water system options or best hot water system Australia‑wide.
If your current unit is leaking, needs constant hot water repair, or you are facing a solar hot water tank replacement, it is worth comparing solar hot water price / cost, heat pump hot water price / cost and modern electric hot water installation side by side. For some homes, a compact electric hot water installation powered by rooftop solar will be the most efficient hot water system; for others, a premium Sanden heat pump or mid‑range Rheem or Rinnai system will strike the right balance between upfront cost and ongoing savings. Where there is existing solar, pairing it with a smart heat pump or solar hot water heating system can turn excess daytime generation into free showers.
