I posted a thread hoping to determine whether or not leaving my engine pre heater (a 500w ceramic heater ducted to the lower cowl of my RV7A) on all the time was a contributor to moisture formation inside the XIO 360. I also run my engine dehumidifier all the time also. The thread went on and on with many different opinions and also some test results.
Subsequently I found the following article written by Ken Sutton who did comprehensive extensive testing on his twin Cessna 310. It pretty much settles the question for me and I am posting it in hopes that it will shed some light for others who ponder the question of non stop preheat and dehumidification to defeat internal engine moisture.

I'd appreciate comments if any
