This is a great unit, i use it with my C180- i travel to remote sites for work, plug this into a generator and tent the engine, at -20c the engine is toasty warm after 12+ hours. - its expensive but the man has to recover his costs, this is not a hair dryer disassembled and stuffed into a yellow box.

Just what I was looking for …smaller than expected so easily fits through cowling

This heater works just like the manufacturer says it will! Read and follow the instructions... Super easy. I initially left this powered on for one week, with three blankets over the cowling. The outside low temps were in the high teens and low 20s, and plane is in an uninsulated hangar. The thermostats work as intended. I checked on it periodically during the week, and it was not running constantly, which was a concern of mine. Engine start up was much healthier than when using oil pan heater, which I will no longer use. I now recommend this heater to everyone. I love that this heater is built just for this purpose.

Just place it in the engine compartment, plug it in, and cover the cowl with moving blankets and the device takes care of the rest. Oil Temps in the mid 50s when Temps in the low 20s.

I’ve had this a week here in Reno. Outside Temps in the morning have been in the twenties. Cylinders and oil temps have been in the 50s so it is doing the job One issue, I have is the cowl on my aircraft (1964 Mooney M20c) does not allow me to insert the heater into the cowl, so the heater is sitting in front just behind the prop. I put an extra moving blanket on and clipped in tight around the prop. The back cylinders end up being a few degrees colder than fronts.
