A hot water cylinder that typically saves up to 10%* on your water heating bill!
This revolutionary hot water cylinder learns a households behaviour and only heats what's needed, saving you on water heating!
What is it?
The way that a traditional electric hot water cylinder works means that you are paying to heat all of the water in your cylinder 24 hours a day, 7 days a week, 52 weeks a year. The Rinnai Smart Cylinder™ has a smart thermostat which learns the pattern of hot water use of your house, and then only heats the water when it knows it's going to be needed, typically saving up to 10% on water heating costs*.
It's easy to use too with an LCD control pad, simply set and forget.
How it works
The smart cylinder has three modes that can be selected using the control pad; IQ mode (smart learning mode), manual mode, and vacation mode.
 
iQ MODE - SMART
Set, forget and save 
When in this mode the Rinnai Smart Cylinder™ will learn one week of your households hot water usage behaviour. After the first week the Rinnai Smart Cylinder™ will apply the savings algorithm and only heat water in the cylinder when it knows it will be needed.
The Rinnai Smart Cylinder™ will constantly monitor the household water usage and update the saving algorithm continuously, ensuring that it is only ever heating water to meet demand.
 
 
 VACATION MODE
In vacation mode the Rinnai Smart Cylinder will keep the water at a minimum temperature (6°C) to save power. This will also prevent the water from freezing in colder areas. Select the number of days you will be away for and the Rinnai Smart Cylinder will handle the rest. After the specified time it will automatically revert to the last mode you had it on meaning  you can have a hot shower as soon as you get in the door!
MANUAL MODE
When in this mode the Rinnai Smart Cylinder™will operate as a traditional electric storage cylinder, ideal for when guests arrive.
