    Overview

    Designed specifically for homes with one bathroom and moderate hot water demand, the Rinnai Infinity B16 delivers reliable, efficient performance in a compact, smartly engineered unit. This gas continuous flow hot water system ensures you enjoy a steady supply of hot water exactly when needed—no more waiting or worrying about running out.

    Unlike traditional storage systems, the Infinity B16 only heats water when a tap is turned on, maximising energy efficiency and helping to reduce household energy consumption. With an exceptional 6.1-star equivalent energy rating, it's one of the most economical 16-litre models available, ideal for small to medium-sized households.

    Crafted with Australian conditions in mind, its space-saving profile allows for flexible installation, even in tighter areas. Advanced features like Puretemp technology provide stable water temperatures, enhancing comfort and safety for the whole family. The built-in digital temperature control makes it easy to set and maintain your preferred water temperature.

    Constructed with high-quality Japanese design and manufacturing standards, the Infinity B16 offers long-lasting durability. It’s compatible with both natural gas and LPG models and can be further enhanced with optional hot water controllers for added convenience and user personalisation.

    Whether you're upgrading or installing a new system, the Infinity B16 is a dependable, eco-conscious choice built to withstand harsh environments while delivering precise, continuous hot water.
    Compact Space-Saving Design

    Built with modern homes in mind, the Compact, Space-Saving Design ensures easy installation in smaller outdoor or utility spaces. Despite its slim profile, the system delivers full performance, providing reliable hot water without taking up unnecessary room or limiting installation flexibility.

    Precise Temperature Control

    Enjoy greater safety and comfort with Precise Temperature Control, featuring an intuitive digital display and easy-to-use interface. This smart function allows households to set exact water temperatures, reducing risks of scalding while providing consistently comfortable hot water tailored to individual needs.
