When additional heating support is needed during colder conditions, the MRCOOL HHK-10 delivers dependable performance to help maintain consistent indoor temperatures. It reduces strain on the primary system while supporting steady, comfortable heating across the space.
Built for integration with compatible systems, this MRCOOL PRODIRECT 10kW Electric Heat Kit provides controlled heating output to support stable operation. It functions as a MRCOOL Top Discharge Air Handler Heat Kit within PRODIRECT systems, helping maintain reliable warmth while allowing the system to respond efficiently to changing temperature demands. This makes it suitable for setups that require additional heating without compromising overall performance.
The unit features a user-friendly design that supports straightforward installation and precise thermostat control for accurate temperature management. Built-in overheat protection enhances safety, while its durable construction ensures long-term reliability. The compact design allows efficient integration into compatible systems, supporting consistent operation in everyday use.
One customer noted, “Before installing the heat kit, their air handler alone wasn’t keeping up during colder nights, and some areas were unevenly heated. After adding the heat kit, heating became more balanced, the system responded faster, and overall comfort improved.”
This demonstrates improved heating consistency, faster system responsiveness, and dependable real-world performance. The HHK-10 is a practical solution for supplemental heating, safe operation, and efficient integration with PRODIRECT systems.
