Townsville's tropical climate and STC Zone 1 location make it one of Australia's best locations for solar and heat pump hot water performance and value. Like Cairns, Townsville is in a cyclone risk zone (Tropical Cyclone Risk Zone D), which means roof-mounted solar hot water collectors must meet strict cyclone wind loading standards. Ergon Energy supplies Townsville's electricity. This guide covers hot water system costs in Townsville in 2026.
