With a compact and slimline design, it offers a space-saving solution that doesn’t compromise on performance or convenience. Designed specifically for Australian conditions, the Infinity B12 ensures a steady and consistent supply of hot water, regardless of variations in water flow or ambient temperature.

    Operating with high efficiency, the B12 only consumes energy when a tap is turned on—making it an ideal choice for eco-conscious users looking to lower their utility bills and environmental impact. Its 6.2-star equivalent energy rating underscores its superior performance, setting a benchmark as the most efficient 12-litre continuous flow system on the market.

    Built with user comfort and safety in mind, the Infinity B12 includes advanced features such as Puretemp stability control for consistent water temperature, precise digital temperature display, and robust safety monitoring.
