In postcode 3568, demand is shaped by a mix of families and a large over‑65 population, so hot water needs to be dependable as well as affordable. Hot water energy use can be one of the biggest chunks of a power bill, so choosing the most efficient hot water system has a real impact.

Hot Water Rebates, Tariffs & Savings
For hot water VIC homes, rebates are a big part of the story. Many Gannawarra households are looking to replace old gas or electric units with efficient options, helped by a mix of Federal and Victorian hot water rebate VIC programs. The Australian Government’s Small‑scale Technology Certificates (STCs) effectively discount eligible heat pump and solar hot water price / cost at the point of sale. On top of that, state programs can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when moving away from gas.
These incentives can cut the upfront hot water system price / cost by a substantial amount, often bringing the heat pump hot water price / cost or solar hot water price / cost closer to a standard electric system. With lower running costs, many Gannawarra households see payback periods shrink to just a few years, especially when they use timers or solar‑diversion to run their electric hot water installation or energy efficient hot water system when rooftop solar is generating. For homes without gas, an all‑electric setup using a quality system such as Sanden heat pump or a well‑designed Rheem or Rinnai solar hot water system can be one of the smartest upgrades available.
