The Rinnai hot water Instantaneous/Continuous systems work by heating water as it passes through the unit so you only use energy when you turn the tap on. This process makes the Rinnai hot water systems extremely energy efficient systems, by only heating water when required. In turn, it reduces your running costs, as well as greenhouse gas emissions.

The compact Rinnai 16 will continuously supply hot water to one bathroom homes. It's also the most energy efficient 16L continuous flow system on the market, and is available in LP or Natural Gas.

 Please note this is NOT the INFINITY model - it is B16
