The Rinnai INFINITY A-Series are continuous flow hot water systems for residential applications. These water heaters produce endless hot water, and unlike electric cylinders, are energy efficient as they are only on when you need hot water.

Designed and made in Japan, the Rinnai INFINITY A-series are continuous flow gas hot water heaters with inbuilt frost protection. They have electronic ignition and require electricity to operate.

Suitable for mains and medium pressure residential applications.
They are designed to be externally mounted on an outside wall and located as close as practicable to the most frequently used hot water outlet(s), to reduce the delay for hot water delivery.
They are not suitable as a spa or swimming pool heater.
They are not suitable for commercial installations.
They are also not suitable as a gas boost for solar installations, or connection with an iHeat, as the temperature cannot be set high enough.
Hard or acidic water will need to be treated to use this product.

There are four models to choose from depending on your hot water needs. Model numbers represent hot water capacity, for example the A26 produces 26 litres of hot water per minute at a 25 ° Celsius rise.

Please Note: If the inlet pressure or flow rate drops below the minimum values stated above, operation of the INFINITY is not guaranteed. The unit requires both minimum flow rate and pressure to operate correctly.
