Plugging in, How much time needed?

[DENALI]

How long do you plug your truck in for before starting? Is there an optimum time? I am wanting to set my plugin on a timer so i need to know how long to set it to come on before i want to jump in it and leave for work. Thanks

i have mine set to go on at 3am and i leave around 7

i think 3-4 hours should be long enough

x2^^^^^. I've been told after 3 hours its as hot as it will get.

All night long.
Plug it in when I get home and forget it until I drive.

This is what I used to do. These heaters use alot of current but I'm not sure how long it would take to justify the $10-$20 a timer costs. I figured I would have my diesel a long time so I could justify it.

it's a 1000 watt heater so you're looking at 1KWH of electricity per hour of usage

~2.5 hours or so mine is set for

How much is elcetricity per KWH. (I've only been renting this house a few weeks so I havn't got an electricity bill yet)

I plug it in for around 3 hours with a timer, but only when it is below 20deg. When it's above 20deg I don't plug it in.

The energy consumption is around the same as a little space heater so it probably cost around 50cents to $1/day depending on how long you plug it in.

I think the powerstroke supplement that came with my owner's manual recommended 3 hours, but it really depends on how warm you want it to be. If I do mine for 3 hours on a 20* day it will be about 85-90 on both ECT and EOT. If I do it over nignt, it's usually around 130* for both, but once I start it the warm fluid cycles through and levels out around 100*.
