Rinnai B16 Continuous Flow Natural Gas Hot Water System
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 B16Please Note: Any hot water unit preset above 50oC requires a plumber to install an approved Tempering Valve on the hot water branch line to the bathrooms to set the water at a maximum of 50oC. This allows for the hotter water to be supplied to the kitchen & laundry which is best for cutting greases and rinsing.

I installed one in a previous house I owned, so I speak from experience! Why would you heat up a large amount of water either by solar, electric or gas, sitting there slowly cooling down, heating it up again and than add cold water as you use it? Even with solar hot water you need a booster. The instantaneous gas is the only logic solution regardless of the price to obtain / installation to replace an existing tank system. Even better in a new house installation. Set the temp. so you shower at the right temp. without adding cold water or use for the washing machine or dishwasher.

Wouldn't go past the Rinnai brand. Have bought several over the last few years and never have any problems with them. They are super reliable and just keep working and have a ten year warranty!

We needed to replace our existing instant hot water system. This product came highly recommended and was able to increase the capacity of our old one with better performance and at a great price. Our plumber came to do the installation and even he was impressed.
I have had this for a month now and it has worked flawlessly. I love the remote you get for adjusting the temp, at tne moment i have it at 44 degrees and when it starts to get colder all i have to do is press the remote i have in the kitchen to a higher temp, easy. Will wait to see my next gas bill which i expect to be less tnan my previous one with the storage tank.
