The Rinnai iHeat is a ducted home heating system that uses hot water from your Rinnai INFINITY* continuous flow water heater to warm air and circulate it around your home. The Gas central heating system can also be zoned to only heat the areas you are using. Zoning kits are available from ducting suppliers, refer p. 2 of the 'Ducting Guidelines' PDF at the bottom of the 'Technical' tab.

Whole home heating that is fast and efficient
With the same high efficiency as your Rinnai INFINITY continuous flow water heater and heat output of 20 kW, the Rinnai iHeat will be efficient and fast at heating your home.

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.

* The Rinnai INFINITY A-Series is not suitable for use with an iHeat as the  system cannot be set high enough to run both hot water and heating.
