Considering things like condensation, how long to keep heat on? Timer?

I know a guy who uses an aquarium pump and a container of desiccant to circulate dry air through the crankcase. In the exhaust stack and out the oil filler tube. Seems like overkill to me if you change the oil every 25 hrs and fly at least every 2 weeks.I've heard stories of it causing additional condensation inside the engine...
My experience. My airplane is spoiled and spends the winter in S. Florida. Returning back to Canada last spring we ran into some chilly weather. After an overnight in Virginia the morning temp was around 30F and the 0-360 in my 4 would not start after repeated attempts. I don't have a primer.
Someone in the FBO asked if I had a Reif sump heater? Yes I do.
Plugged it in for 15 minutes and it started right up.
I'm a believer.
