Product Description 

 

MRCOOL® Signature Series 10kW Electric Heat Kit for Stud Mount Air Handlers

The MRCOOL® Signature Series 10kW Heat Kit (MCAEHWD10X1AA) delivers maximum auxiliary heating output for homes that demand dependable comfort in harsh winter climates or larger living spaces.

Producing 10,000 watts of electric heat, this high-capacity heat kit is designed to supplement your heat pump during extreme cold, support defrost cycles, and provide reliable emergency heat when outdoor temperatures drop well below freezing.

Built specifically for MRCOOL Signature Series R-454B stud mount air handlers, the 10kW heat kit installs directly inside the cabinet for clean airflow integration and proper electrical balance. Because it’s factory-matched, you avoid compatibility issues, airflow restrictions, or performance loss common with aftermarket solutions.

This size is ideal for cold-climate regions, larger homes, or homeowners who want maximum heating confidence without relying solely on heat pump operation. When conditions demand more heat, the 10kW kit delivers fast, consistent warmth you can feel.

If you want the strongest backup heat option available for a stud mount Signature Series system, the MRCOOL® 10kW Heat Kit is the correct, system-approved choice.
