Ensure uninterrupted home heating with the MRCOOL Emergency Heat Kit—a reliable supplemental heating solution designed for MRCOOL HyperHeat Central Ducted Air Handlers. This electric heat kit serves as a backup heat source during extremely cold weather or in cases where the primary heat pump is temporarily inoperative.
A heat kit (or electric heat strip) acts as a secondary heat source, installed inside the air handler. Often compared to a "large blow dryer," it generates direct electric heat, distributing warm air throughout your duct system when:
🔹 The heat pump is temporarily down and in need of service.
🔹 Outdoor temperatures drop to extreme lows, where the heat pump may struggle to maintain indoor comfort.
🔹 A rapid heating boost is needed, especially in colder climates.
While not as energy-efficient as heat pumps, heat kits are designed for short-term use, ensuring your home stays warm when needed most.
Each MRCOOL HyperHeat Emergency Heat Kit comes with the necessary electrical components for seamless installation inside the MRCOOL HyperHeat Central Ducted Air Handler.
