Hot Water Rebates, Tariffs & Savings
Across VIC, interest in efficient hot water is being driven by generous incentives. For Richmond South homeowners, federal Small‑scale Technology Certificates (STCs) can reduce the upfront cost of a solar hot water system or heat pump unit, while Victorian schemes often provide a heat pump hot water rebate or solar hot water rebate on top. There are also electric hot water system rebate offers in some programs, particularly when you are replacing gas.
These hot water rebate VIC incentives can cut the effective system cost by a substantial percentage, often shaving thousands off a premium heat pump or solar system. That means the payback period on an energy efficient hot water system can drop to as little as three to seven years, especially if you also have rooftop solar and use timers or smart controls to run the system when your solar is producing. Over the life of the unit, that can mean many thousands saved on bills, particularly when you compare efficient electric hot water vs gas hot water on today’s tariffs.
If your existing unit is old, noisy or running out of hot water, it is worth checking whether a heat pump hot water system, solar hot water system or modern electric hot water system could be the most efficient hot water system for your home.
