Backed with extensive warranties and fully qualified after sales teams, Rinnai is proud to be the No.1 choice for Continuous Flow Hot Water. Rinnai hot water systems fulfil your requirements for new or existing projects, providing the optimum solution by using both individual and multiple appliances manifold.

Rinnai employ innovative manufacturing and testing techniques to deliver unparalleled levels of safety, comfort and efficiency.

The Rinnai water heaters fall into 3 different sections: Domestic, Entry Level Commercial and Commercial.

Domestic Internal Water Heaters

16i and 11i

Sudden changes in water temperature, causing cold showers or scalding hot baths are a thing of the past. Unlike many competitors, the water temperature you set is the water temperature you get. So, if you are showering at, say 42°C, and someone turns on a tap elsewhere in the house, the temperature will not vary.

Rinnai Infinity 16i/11i is the perfect solution to hot water requirements for domestic properties/dwellings and light commercial use. It is designed to allow maximum flexibility when choosing where to install it, as it does not have to be mounted on an external wall. The Rinnai Infinity 16i/11i is designed for use directly off the mains and therefore there is no need for large, ungainly storage vessels.

Domestic External Water Heaters

17e

The Rinnai 17e external water heater has the added advantage that the unit is externally mounted. This feature gives greater flexibility at the design stage and can offer an alternative solution where flue runs are problematic or internal space is not available.
As with all units in the Rinnai range the 17e has full frost protection. A range of external ancillary items including a pipe cover box and security cage are available where necessary. Capable of flow rates of up to 510 litres per hour at a 50°C rise, the 17e is suitable for multiple applications, such as cafés, small restaurants and kitchen facilities.

K26i - Now Obsolete 

The condensing technology within the K26i delivers up to 107% gross thermal efficiency, which translates to significant energy savings when compared to their conventional counterparts.

• Energy efficient - K26i 107% net efficiency*
• Saves space, water and energy
• Limitless applications
• Compact design with internal and weather-proof external models
• Temperature accurate hot water delivery

Rinnai's unique condensing technology incorporates two heat exchangers to achieve optimum water heating generated from every cubic metre of Natural Gas or LPG. These compact wall mounted water heaters capture residual heat from its flue gases and transfer it into the water being heated. The K26i also incorporates multiple safety features ensuring temperature accurate hot water delivery and eliminating scalding.
