    Dometic Heat Strip 120 V non-ducted

    Posted by Henry Mearns on Mar 18th 2021

    For those the camp all 4 seasons this is a nice additional source of heat. It utilizes the "optional heat" position on your non-ducted AC unit and converts it to a heater with the approximate capacity of a small space heater. The benefit is that it takes up NO floor space and has the much higher airflow of the AC fan system. With two of these units and an optional electric fireplace we only use the propane heat on the coolest days or briefly in the mornings to warm things up quickly.
