When a heat pump struggles to keep up during a deep freeze, indoor air can quickly lose its warmth. The MRCOOL MHK05B acts as a reliable secondary heat source, activating to maintain a consistent, comfortable temperature throughout your home during extreme weather events.
This MRCOOL 5 KW Modular Blower Heat Strip with Circuit Breaker is specifically engineered for use with MRCOOL Signature Series modular blowers. It provides 5 kilowatts of electric resistance heating to supplement the primary system. The unit is designed for internal installation, allowing it to provide immediate heat during the defrost cycle or when outdoor temperatures fall below the heat pump's effective range.
The inclusion of an integrated circuit breaker simplifies the installation process and provides essential overcurrent protection for the electrical circuit. Its modular design ensures a precise fit within the blower cabinet, eliminating the need for complex field modifications. This setup prioritizes both safety and efficiency, ensuring the hardware operates within its intended parameters.
One customer noted:
“Our house used to get a chill every time the unit switched to defrost mode in the winter. After installing this heat kit, the air stays warm without any noticeable dips in temperature.”
The MRCOOL MHK05B offers a practical and effective way to ensure your HVAC system provides dependable warmth year-round. It is an essential addition for maintaining climate control in colder regions.
