The Rinnai iHeat is a ducted home heating system that uses hot water from your Rinnai INFINITY water heater to warm air and circulate it around the home. The gas central heating system can also be zoned to only heat the areas you are using.
How it works
The Rinnai INFINITY provides hot water to the iHeat air handler unit (heat exchanger). The heat exchanger extracts the heat from the hot water and transfers it to a steady stream of air. This air is fed into the ducting system and is distributed into each room.
Hard or acidic water will need to be treated to use this product.
Suitable for
Homes with a gas connection and an existing Rinnai INFINITY* (or planned installation).
Homes where the iHeat unit can be installed in a ceiling space, or under the floor—subject to clearances shown below. The unit cannot be positioned outside.
* The Rinnai INFINITY A-Series is not suitable for use with an iHeat as the system cannot be set high enough to run both the hot water and heating
Clearances
The iHeat should be positioned so that the LED's are easily visible through the window of the control board. Avoid positions that make access to the iHeat and removing components difficult.
