MRCOOL 15kW Heat Kit with Circuit Breaker for TruInverter Air Handlers

The MRCOOL 15kW Heat Kit (MCAEHFD15X1BA) provides maximum-capacity supplemental and emergency heating for MRCOOL Signature Series TruInverter air handlers. Built for larger homes, colder climates, and high-demand applications, this heat kit ensures your system can deliver reliable warmth when your heat pump needs serious backup.

When outdoor temperatures drop to extreme levels or the heat pump cannot keep up, this heat kit activates to provide direct electric heat through your duct system. It’s designed to maintain comfort when conditions are at their worst—because “almost warm” is not a real setting.

What Does a Heat Kit Do?

A heat kit is installed inside your air handler and provides direct electric heat when your heat pump alone cannot maintain indoor temperatures. It acts as a supplemental or emergency heating source, ensuring continuous comfort even in extreme conditions.

Often compared to a high-capacity heating element, it warms air as it passes through the system and distributes heat throughout your home via ductwork.

When Is a Heat Kit Used?

• During extreme cold weather when heat pump efficiency drops
• As emergency heat if the outdoor unit is not operating
• In high-demand heating situations for larger spaces

While heat kits are less energy-efficient than heat pumps, they are essential for maintaining reliable heating performance in colder climates and large-scale applications.

Installation Notes

This heat kit is designed for installation inside compatible MRCOOL air handlers. Due to the higher electrical load, professional installation is strongly recommended to ensure proper wiring, breaker sizing, and safe operation.

Why Choose the 15kW Heat Kit?

If you need the highest level of backup heating capacity available for your system, the MRCOOL 15kW heat kit delivers. It is ideal for large homes, colder regions, and applications where consistent heating performance is critical, providing dependable warmth when your system needs it most.
