Coleman 38203-4551 Electric Heat Strip Assembly

This is a heat strip for Coleman-Mach Heat Ready Ceiling Assemblies, designed to provide a supplemental electric heating option for your RV adding 5,600 BTU heating output to your air conditioner. The heat strip works by using electric resistance to warm the air as it passes through your air conditioning unit, helping to take the chill out of the air on cool mornings and evenings. While not a replacement for a furnace, it offers a convenient and efficient way to maintain comfort in mild to cool temperatures without relying solely on propane.
