Hi, Guest
Back in the day (well days when I had the wagon), I would plug the car in before going to bed and left it on overnight.
I've read that 4 hours is more than enough.
here we go:
"Why Four Hours?
A study conducted at the University of Saskatchewan found that about 95% of the maximum possible temperature is obtained by the end of the fourth hour. The results indicate that keeping the block plugged in for more than four hours (where there is continuous power) is a waste of electrical energy.
