Rinnai iHeat
Rinnai iHeat central heating code
RAHU20
Description
The Rinnai iHeat is a ducted home heating system that uses hot water from the Rinnai INFINITY
continuous flow gas hot water heater to warm air and circulate it around the home. The Rinnai iHeat
is controlled via a wall thermostat that has three fan speed settings and can be programmed to run on
timers.
How it works
The Rinnai INFINITY continuous flow gas hot water heater 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. Water is
returned to the Rinnai INFINITY for reheating.
Suitability
The Rinnai iHeat may be retrofitted to any home with an existing Rinnai INFINITY continuous flow water
heater, or both units can be installed simultaneously.
Hard or acidic water will need to be treated to use this appliance.
Positioning considerations
The Rinnai iHeat can be installed in the ceiling space or under the floorsubject to the clearances
shown. It must not be mounted in areas subject to direct splashing—this is relevant to underfloor
installations that could be exposed to water. The unit cannot be positioned outside.
Prior to purchase of a Rinnai iHeat a customer site visit is required to ensure the correct system is
specified and that the Rinnai iHeat can be successfully installed.
