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.
Four models to choose from depending on your hot water needs (A16, A20, A24, A26*). Use the Rinnai INFINITY model selector in the 'Suitable for' tab to work out which model is suitable for you.
* Model numbers represent hot water capacity, for example the A26 produces 26 litres of hot water per minute at a 25 degree Celcius rise.
• external residential applications only
• mains and medium pressure systems
