Engine heating pads

[plowboy]

Do you folks leave your silicone heating pads plugged in all through the cold weather, or just plug them in when you plan on flying?

Only before flight, leave on to long condensation can build. also on cyl straps you can cook all the oil off and create issues. I know some have timers they can remotely operate that work well... Im to poor so I drive to the hangar to plug in the night before and have a manual timer

I only plug in the night before I fly
