The Carrier CRHEATER101A00 Heater Kit is an essential field-installed accessory designed to provide reliable supplemental heat for small rooftop units (RTU) and electric cooling or heat pump systems. Engineered for seamless integration, this 4.4kW electric heater operates at 208/240V and is optimized for 3 to 12.5-ton units. As a veteran-grade HVAC replacement part, it ensures precise climate control during peak winter loads without the need for complex internal modifications. This kit utilizes high-grade heating elements and OEM electrical connectors to maintain system integrity and airflow efficiency.

For contractors, the Carrier CRHEATER101A00 represents a standard-duty solution for adding auxiliary heat to existing Carrier, Bryant, or Payne rooftop installations. The module-based design allows for clean mounting within the supply fan compartment, following strict NEC Class 1 wiring standards. By utilizing 208/240V single-phase power, it delivers 3.3/4.4 kW of heating capacity, making it a staple for commercial and residential supplemental heating applications where consistent discharge temperatures are critical for occupant comfort.
