Hot Water Rebates, Tariffs & Savings
With rising energy prices, many Tooronga households are now comparing heat pump vs solar hot water, or weighing solar hot water vs electric hot water when replacing a failing unit. The good news is that Australian Federal Government incentives, like Small‑scale Technology Certificates (STCs), can reduce the effective solar hot water price or heat pump hot water price by hundreds of dollars. On top of that, Victorian state programs regularly offer a heat pump hot water rebate or solar hot water rebate, and sometimes an electric hot water system rebate when you are replacing inefficient units. These hot water rebate VIC schemes can cut the upfront hot water system price or cost by a substantial percentage, especially when combined with installer discounts.
