Hot Water Rebates, Tariffs & Savings
For Hotham residents, the numbers get even better once you factor in rebates. Federal incentives like Small‑scale Technology Certificates (STCs) can cut the solar hot water price / cost or heat pump hot water price / cost by a substantial amount at the point of sale.

There are also electric hot water system rebate options and schemes that encourage moving from gas to efficient electric systems, improving the economics of electric hot water vs gas hot water.
When you combine a solar hot water rebate or heat pump hot water rebate with STCs, the effective hot water system price / cost can drop by 30–50% in some cases. That can shorten payback periods to just a few years, especially if you already have rooftop solar and use timers or solar diversion to heat water during the day. Many households see hundreds of dollars per year in savings, which is why interest in heat pump vs solar hot water comparisons is growing quickly in Hotham.
