Hot Water Rebates, Tariffs & Savings
Across Grovedale East, more households are replacing old gas or a basic electric hot water system with options like a heat pump hot water system, a modern electric hot water installation paired with solar, or a quality solar hot water system.

Combined, these rebates can reduce the hot water system price by a substantial percentage, often trimming thousands off the heat pump hot water price or solar hot water price.
