roughly 60–70% less electricity than a standard element. Excellent for Bateau Bay's
mild climate, where the system runs efficiently year-round.

Bateau Bay has no reticulated natural gas — LPG is the gas option. LPG instantaneous
systems deliver endless hot water and are popular where off-peak electric isn't cost-effective.
Requires a licensed gas fitter for installation.
