Hot Water Rebates, Tariffs & Savings
Right now there is strong interest in hot water VIC upgrades as residents replace old gas or electric units with efficient options. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump models, effectively cutting the solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of this, state‑based hot water rebate VIC programs can offer a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate for qualifying homes, further reducing the hot water system price / cost.
For a typical Comet Hill family, these hot water rebate VIC schemes can slash upfront costs by a substantial percentage and shorten payback periods to just a few years, especially when a heat pump vs solar hot water choice is paired with rooftop PV. Many locals use timers or solar‑diversion controls so their energy efficient hot water system runs mainly on excess solar, stacking extra savings on top of the rebates. With the right setup, solar hot water vs electric hot water or electric hot water vs gas hot water comparisons usually show clear long‑term bill reductions.
