Hot Water Specialist’s Review of the Rinnai B16 Continuous Flow


5 star Value


4.5 Stars


4.5 Stars

The Rinnai B16 is the go to product if you are looking for a continuous flow hot water system. You get a product that has Rinnai’s great reputation for a great price.

The Rinnai B16 took over where the Rinnai V1500 took off. It is virtually the same as Rinnai’s premium brand- the Rinnai Infinity 26.

The differences between the Rinnai Infinity series and the Rinnai Builder series are the display window and warranty.The heat exchanger is made out of copper. We have never had a heat exchanger fail on a Rinnai continuous flow that is under 14 years old in a domestic application.

The benefits of the Rinnai B16 Continuous Flow Hot Water System

Saves you money on your gas bill
6.1 star gas rating; This means you will save close to 1/3 of the gas per year compared to a traditional 3 star gas storage hot water heater
Temperature adjustment
Through the printed circuit board the temperature can be increased slightly which is great for the dishwashing
*hint: There is an instruction manual inside the hot water heater on how to do this. Also check out this video for more information

You cannot beat the Rinnai brand reputation. They are the name in continuous flow hot water systems.
