What Does a Heat Kit Do?

A heat kit provides direct electric heat inside your air handler when your heat pump cannot maintain indoor temperature on its own. It acts as a supplemental or emergency heat source, ensuring consistent comfort even in extreme conditions.

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

When Is a Heat Kit Used?

• During extreme cold weather when heat pump performance decreases
• As emergency heat if the outdoor unit is not operating
• In high-demand heating scenarios for large homes or open spaces

While heat kits are less energy-efficient than heat pumps, they are critical for maintaining reliable heating performance in cold climates and high-capacity systems.

Installation Notes

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