Product Features & Fitment

This electric heat strip mounts seamlessly inside the existing internal ceiling plenum, integrating directly into the dedicated heater bay of your indoor air distribution box (ADB). Running entirely on 120V electrical current, it warms incoming ambient cabin air as it moves across the resistance element before blowing it through your ducted or non-ducted louvers. It is an exceptional solution for shoulder-season travel, offering exceptionally quiet cycling and near-instant thermal delivery compared to the noisy mechanical startup of standard under-floor RV furnaces.
