Ideal for households with 1 to 2 bathrooms or up to 3 in warmer climates, this 26-litre system ensures a consistent and powerful supply of hot water without running out. Unlike traditional storage systems, it heats water only when needed, helping reduce energy consumption and environmental impact.

    With a 6-star equivalent energy rating, the Infinity B26 offers outstanding efficiency and low running costs. Its Puretemp™ temperature stability technology ensures water temperature stays consistent, even when multiple outlets are in use, while the digital status monitor provides clear feedback on operation. The compact and space-saving design allows for flexible installation, making it suitable for a range of residential settings.

    Engineered to withstand harsh Australian conditions, the unit also features advanced safety systems and precise temperature control for added peace of mind. Whether you’re upgrading your current setup or installing in a new build, the Infinity B26 integrates seamlessly with a range of optional Rinnai controllers to enhance convenience and control. Built on quality Japanese design and manufacturing, and supported by a 25-year heat exchanger warranty, this system combines long-term durability with high performance to deliver hot water comfort every day.
    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.

    Puretemp Technology

    Engineered for comfort, Puretemp Technology keeps water temperature steady even when flow rates vary. This advanced system eliminates sudden fluctuations, delivering a smooth and consistent hot water experience every time, ensuring safety, reliability, and comfort across all household uses.

    Energy-Efficient Operation

    With a 6.0 Star energy rating, the unit operates with exceptional efficiency by heating water only when needed, minimising energy waste and reducing overall gas usage. This on-demand functionality ensures sustainable performance, making it a smart choice for eco-conscious households seeking reliable, energy-efficient hot water solutions.

    Optional Hot water Controllers

    Enhance convenience with Rinnai’s BC145 and MC145 controllers, designed to give precise fingertip control over water temperature.
