Hot Water Rebates, Tariffs & Savings
Around The Basin, more households are comparing heat pump vs solar hot water and even solar hot water vs electric hot water when their old gas unit or electric storage tank starts to play up. Federal incentives such as Small‑scale Technology Certificates (STCs) can lower the solar hot water price / cost and heat pump hot water price / cost, while Victorian hot water rebate programs can further reduce the upfront hot water system price / cost for eligible homes. A heat pump hot water rebate, solar hot water rebate or electric hot water system rebate can effectively knock a substantial percentage off the install, shortening payback times to just a few years, especially if you already have rooftop solar or use timers and solar diversion to heat water during the day. For many households, that means hundreds of dollars per year off bills with a modern, energy efficient hot water system and fewer surprise hot water repair visits.
Whether you are comparing electric hot water vs gas hot water, looking at Rheem solar hot water or Rinnai solar hot water options, considering a Rheem heat pump hot water or premium Sanden heat pump, or needing solar hot water repair or hot water repair on an older unit, it pays to get local advice. Hot water VIC incentives and hot water rebate VIC programs change over time, so a knowledgeable installer can help you navigate the latest offers and find the most efficient hot water system for your household size, budget and roof space.
