Smart, Plug-and-Play Operation

Up to 3 Stages of Operation

13KW and higher sizes will be available in 3-stage configuration. However, these Heater Kits will be able to run in 2-stage mode on existing Rheem Air handlers.

Backward Compatibility

The new heater kits are fully backward compatible and can be used with existing Rheem Air Handlers, manufactured after 2016, by using an adapter, Part Number 45-106229-04.
