I have mine set on a timer for 3hrs.
I live in Iowa, so the winter nights are consistently in the low teens to
below zero.

In Ga. I would think 1hr would be plenty if you get down in the low 20's F.

1 hour doesn't seem to make a difference.

2 hours really helps.

3 hours is like a summer day.

That's exactly the same way I run mine. Same results.

I run mine 2-3 hours. I have a timer that I set for about 3 hours before I expect to leave. It also depends on how hard your car is to start, I don't really need to plug mine in I just do to reduce wear and get heat faster.

But anything over 3 hours seems like overkill.

I take my advice from Joe Walsh, it gets plugged in "All Night Long"

no fancy timers or getting up at 2am to plug the car in

More than 4 hrs. you get no additional heating benefits. Just a bigger electrical bill.

When I recently rebuilt the top end of by new SD, I put a block heater in. It was nice to have a toasty warm block to work with outside.

However, this car is so easy to start. Heck, I've started it easily at 10 deg WITHOUT GLOWPLUGS!

My other SD won't easily start below 10 deg without the block heater.

Does anyone know how many watts the block heater consumes?

Athens, GA gets a handful of below freezing days, believe it or not. Recently, it has been close to 70 only to get back into the 20's a few days later. My car starts much better if I plug it in for a couple of hours on colder mornings.
