Hot Water Rebates, Tariffs & Savings

Invermay homeowners are increasingly replacing old gas or electric units with efficient options like heat pump hot water, modern electric hot water or a solar hot water system. Australian Federal Government incentives, such as Small-scale Technology Certificates (STCs), apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount. On top of that, state-based hot water rebate TAS programs can offer a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate on approved models, further bringing down the heat pump hot water price / cost and solar hot water price / cost.

When these rebates are applied, it is common for the installed hot water system cost to drop by a substantial percentage, sometimes cutting payback periods from ten years down to as little as four to six years, especially when paired with rooftop solar.
