At what temperature do you plug in your block heater?

Outdoor timers are pretty common around here and I've never heard of problems. It just becomes routine - you get home from work, plug in your car/truck, and the timer goes off sometime in the early morning before your commute.

Yep, I have a heavy duty outdoor timer and run my trucks block heater off of it and it draws 700 watts.

I keep my LX2610 in a unheated pole barn. During the winter I keep it on the trickle charger and the block heater plugged into a Wi-Fi controlled outlet. Whenever I'm going to use the tractor I'll turn on the outlet for 30 minutes or so to save the wear and tear off a low temperature cold start. I have the connections so that it's easy to connect and I don't have to pop the hood.

Here's what I have in the garage. It's a 50A water heater controller which can be turned on, turned off or set to timer mode. I have a GFCI 20A outlet connected to the timer, and the on/off intervals are in 30 minute increments. In the image below I have the timer set to turn on at 7:00am and turn off at 10:00am so the extension cord plugged into the outlet and the truck will provide power to the block heater for a maximum of 3 hours.
