Rheem 20 kW Commercial Electric Heat Kit — RXHE-AG020CC
The Rheem RXHE-AG020CC is a 20 kW electric heat kit that bridges Rheem's medium- and large-commercial package lines, working with larger RACD (12.5 ton) up to RACG (20 ton) units on 208/230V three-phase power. It installs into the package unit's heater compartment with single-point wiring and a polarized low-voltage plug, delivering roughly 68,240 BTU/h of supplemental electric heat for these bigger rooftops.
Which Package Units Does This Heat Kit Fit?
The RXHE-AG020CC is a factory-matched heater accessory, not a stand-alone unit. It is sized and wired specifically for larger Rheem package units from the RACD 12.5 ton up to the RACG 20 ton, on 208/230V three-phase power. Matching the heat kit to the exact package-unit series, tonnage, and voltage is essential — a kit built for another series or voltage will not fit the heater compartment or wire correctly.
At 20 kW it adds approximately 68,240 BTU/h of supplemental electric heat. The kit ships wired for slide-in, plug-and-play field installation with single-point power connection and a polarized low-voltage plug, and includes over-temperature limit protection.
Compatible package units:
- 12.5 Ton RACD (208/230V) — RACDYB150ACG
- 15 Ton RACG (208/230V) — RACGYB180ACG
- 20 Ton RACG (208/230V) — RACGYB240ACG

Frequently Asked Questions
What is the RXHE-AG020CC and what does it do?
It is a 20 kW factory-matched electric heat kit (heat strip) that installs inside the heater compartment of a compatible Rheem RACD/RACG commercial package unit. It adds about 68,240 BTU/h of supplemental electric heat so a cooling-only rooftop can also provide heating.
Which package units is the RXHE-AG020CC compatible with?
This kit is built for larger Rheem package units from the RACD 12.5 ton up to the RACG 20 ton, on 208/230V three-phase power. See the compatible-unit list above. Match the heat kit to your exact package-unit series, tonnage, and voltage — kits are not interchangeable across series or voltages.
What voltage does the RXHE-AG020CC require?
It is rated for 208/230V, 3-Phase, 60 Hz and must be paired with a package unit on the same supply voltage. Using the wrong voltage kit will not wire or perform correctly.
How much heat does 20 kW provide?
Approximately 68,240 BTU/h (kW x 3,412). Actual delivered capacity depends on the applied voltage and airflow. Size the heat kit to the building's design heating load and the maximum kit size allowed for your unit.
Is the RXHE-AG020CC hard to install?
No. It is pre-wired for slide-in, plug-and-play installation in the unit's heater compartment, with single-point power wiring to a terminal block and a polarized low-voltage plug. Installation must be performed by a qualified technician following the RACD/RACG installation manual.
Can this heat kit be used on its own?
No. It is a factory accessory that only works installed inside a compatible Rheem RACD/RACG commercial package unit. It is not a stand-alone heater.
