MRCOOL Universal 12kW Electric Heat Kit for Packaged Units (MDPHK12D) – Efficient Add-On Heating Solution

When temperatures drop, heating systems can take longer to bring spaces up to a comfortable level, especially during peak demand. The MRCOOL MDPHK12D is designed to provide additional heating capacity, helping improve system response and maintain a more stable indoor environment.

The MRCOOL Universal 12kW Electric Heat Kit functions as a supplemental heating component designed for Universal packaged units. It works in coordination with the main system and activates only when the thermostat calls for extra heat. Because it is designed for packaged configurations, it installs directly into the unit, increasing heating capability without requiring separate indoor equipment or major system modifications.

Built to handle regular use, this MRCOOL Universal Package Unit Heat Kit uses nickel chromium heating elements that support consistent heat output over time. It also includes integrated overheat protection for safer operation and is designed to accommodate higher electrical demand through multiple branch circuit capability. The overall design keeps installation practical while maintaining dependable performance under varying conditions.

One customer said, “Our system had trouble keeping up during colder periods, and it often took a while for the space to feel comfortable. After installing the heat kit, it warmed up much faster and stayed at a steady temperature without constant adjustments.”

This suggests the unit helps improve system response under higher demand while maintaining more consistent indoor conditions.

In everyday use, it works as a practical support component, providing additional heat when needed without making the system more complicated to manage.
