Hot Water Rebates, Tariffs & Savings
For Macgregor households, there is strong interest in replacing old gas or electric hot water with efficient options like a heat pump hot water installation, solar hot water installation or a modern electric hot water installation that works with rooftop solar. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump hot water and solar hot water systems, effectively cutting the hot water system price at the point of sale. Queensland‑based programs and retailer offers can stack on top, and some plans support off‑peak tariffs that further reduce the running cost of an electric hot water system.
With a solar hot water rebate or heat pump hot water rebate, it is common for Macgregor homeowners to see the upfront heat pump hot water price or solar hot water price reduced by a substantial percentage, turning a big purchase into a more manageable hot water system cost.
