Hot Water Rebates, Tariffs & Savings
Garden City homeowners are increasingly replacing old gas or electric hot water with efficient options like heat pumps, newer electric hot water systems and solar hot water. Federal incentives, such as Small-scale Technology Certificates (STCs), can lower the effective hot water system price for eligible systems, including rheem solar hot water, rinnai solar hot water and leading brands like sanden heat pump units. On top of that, Victoria offers state-based heat pump hot water rebate and solar hot water rebate programs, and in some cases an electric hot water system rebate, which can take a big chunk off the upfront heat pump hot water cost or solar hot water price.
