Coleman 472334551 Electric Heat Kit: Efficient Heating Solutions for Ultimate Comfort Review

The heater did not meet my expectations. It works, heats up and cools down very slowly, making it difficult to set the thermostat/temp, even when it comes to taking the cold out. I recommend if you buy it it works better if you cover a vent.

I installed this unit in my Coleman Mach 8 cub 9000b btu AC unit. This heater is a 6000 BTU unit. This unit draws 13.5 amps at 120 volts making it a 1620 watt heater. The heater element temperature reached 120 degrees Fahrenheit and the outlet air temperature was 80 to 85 degrees Fahrenheit, the ambient air temperature was 65 degrees Fahrenheit.

Was fairly easy to install from inside the bus. Minimal moderate effort and works well. Heats up quickly on cool days. The reason for installing inside was that when installing from the roof of the car, after removing the protective cover from the air conditioner, I noticed that it is a sealed unit and should not be disassembled to close this heater install, as there is a risk of perpetual leakage in the device. Mine is simply installed from the inside and works very well.

Screws on and heats up great. I won't know how well it works until the temp drops, but if my calculations are correct, it's a 1700 watt heating element, so it should work great on my small RV. I've read that it can be installed from inside the camper, but after a few tries and a few bent fins on the air con I gave up and pulled the cover off the top and it went in easily! It would be nice if the heating was integrated and always there.
