Hello all I was just wondering how many watts it takes to power the block heater on my truck 97 with 7.3. What I want to do is get a seperate deep cycle battery and a power inverter so I can keep my truck nice and toasty this winter when I am at work. thanks

Ya really only need to run the block heater about 2 hours before start up. That'll get it nice and toasty for your trip home. Cheap outdoor timer from a hardware store will cover that.

As to how many watts probably something around 500-700 I believe is the norm.

your block heater will run off a 110 volt plug in, so a battery isnt gonna cut it.....

your gonna need a whole lot of batteries to keep an inverter that size running, might be cheaper and easier to run a LOOOOOONG cord from home to work lol

I checked the current draw on mine last winter and it pulled a little over 8 amps on 120 volts. Which would be about 1000 watts.

I know the block heater runs off 110 thats why I said I would be using a POWER INVERTER (marc) thanx for the info jim. I have a 2000 watt inverter and I was just wondering if it would be enough.
