SEQ's climate is ideal for solar hot water all year round.
How It Works & What to Consider
Split systems
Collectors on the roof with the storage tank at ground level, circulated by a pump — ideal where roof load or aesthetics matter.
Thermosiphon (roof-mounted)
Both the collector panels and the storage tank sit on the roof, using natural circulation with no pump — simple and reliable.

A booster ensures you always have hot water on cloudy days, for the best of both worlds.
