Block heaters.

Ok, I have looked for threads on this but haven't found em yet.

I plug in my truck. Tested the current draw. At about 116 volts it draws about 7.8 Amps. Which is a little over 900 watts.

If I plug in my truck in the evening. Morning temps right at the freezing mark. How warm will this block heater keep the engine?

Seams the engine is quite cold in the morning. Starts but with a little more cranking. Cranks for about 4 to 5 seconds before firing. Which from what I understand is not bad at all.

What should I expect from that block heater?
Should the cab heater put out at lease a little warm air once I get the truck running?

Thanks.

If i plug my '01 in overnight it will stay warm enough for the stock water temp guage to read a little over the "low" mark.
And yes, heater is warm as soon as i turn it on.

But we rarely see temps below 20 here in west Alabama. I don't plug in much. Usually if its gonna stay below freezing for a while.

I would think the heaters are all the same wattage in the 7.3's ('95 vs '01)

If that is the case, my heater may not be working properly.
Any idea what the wattage should be?

Should be 1000 watts, rated at 120 volts

The cords are notorious for having/ aquiring shorts in them.
Here's an aftermarket replacement element & cord: 7.3L Powerstroke Block Heater Cord Combo 3500043

Thanks. One more thing to fix.
I have heard there is a 1500 watt heater available.
What is the advice to upgrading versus the 1000 watt?

I plug mine in for about 3 hours (via a 15A Timer) prior to leaving. If I leave the heater control in the defrost setting, it will actually defrost the windshield a bit just sitting there. Starts easier and fairly instant heat (makes mama bear happy). Cheers!

^^^^^ +1 on the timer. At 1000W, you're paying about 15 cents an hour to run it. And any more than about 3 hours makes no difference.

Thanks everyone. Ends like mine is not working. Ghost draw. Must be a shorted wire or a shorted out heater element.

I like the idea of only plugging it in for 30 minutes or so. Minimal power use. So I will see about opting for a 1500 watt heater.

Ok. Got up this morning. Temps in the low 30s again.
Truck had been plugged in all night.
Turned it on. Waited for the wait to start light to go out.
Cranked it for about 10 seconds. It coughed and sputtered and died.
Cranked it again for another 10 seconds and it fired up.
Yup, The block warmer is NOT working.
No heat in the engine at all.

Time to check the cord to see if that is the problem.
If the cord checks out good. Then new block heater and new cord.

Thanks everyone for your help and ideas.
