Wanted to get one so I can heat the water in my 7.3 whole at work for a easier and faster startup. I think it takes 8 or 9 amps to run the heater. Do they make power supply units that will put that out for 2-3 hours? Thanks for any help
Reply:At 9 amps that'd be 1000 watts per hour.... plus losses from the inverter part figure 20 percent.... you're gonna need a *lot* of battery
Have you thought about the mini semi heaters for preheat??? I forget the thread but the well driller from ID on here just put one in his crane.. I think... or in something
Reply:Found it... was his drill rig

Reply:Here's one of the real cheapies.... I was actually going to put one of these in my powersmoke a few years ago... but since i bring my work truck home I don't run my personal rig every day... and the project kind of lost it's imperativeness

I have only had to plug it in 4 times in the 20+ years I have owned it. 2 of those time were when the grid heater solenoids stopped working. The other 2 times I was on a Job in far north Minnesota and it was 25 below zero in the morning for 2 days. The motel I was at had electric outlets at all the parking places so it must be fairly often they get those temps.Last edited by thegary; 01-25-2021 at 09:49 AM.

Reply:In a 7.3, I think what the "block heater" is doing that's most important is to heat, and thin, the Oil (the reason it's located at the oil cooler). HEUI reacts badly with too thick oil, especially when starting with 15w. Switching to 5W synthetic is usually enough to eliminate the actual "Need" (as JohnT points out) unless you're in Real negative numbers (not that Celsius nonsense
) But more commonly, that thin oil becomes needed as Injectors get a lot of mileage on them (200K or so). Is that what's going on for you or are you facing really cold temps?

Reply:Yes the 7.3 block heater is in the coolant, not the oil cooler. Far better in all respects to have a glow plug system in good working order than to rely on the block heater unless you are in severe sub zero temps. Ways to use the block heater when no shore power is available have been hashed and re-hashed on the Powerstroke forums and been proven to be pretty much a pipe dream.Miller Challenger 172Miller Thunderbolt AC/DC 225/150Miller Maxstar 150 STLVictor 100CVictor JourneymanOxweld OAHarris O/ASmith O/A little torchNo, that's not my car.
Reply:just let it idle 2-3 hours. diesels only burnout 1/3 gal per hour. if worried about diesel gumming stuff up, im sure you can figure out a high idle. i have let my duramax sit for 7 hrs 8in the heat on fast idle with dog inside and air running. and my injectors are more susceptible to clogging than yours. the old diesels like yours can do that. common rails diesels, mine, have a LOT smaller injector holes than yours.look at tractor trailers they sit a lot longer than 2-3 hrs. many, many times overnight and all next day. no problem.my kubota tractor i let sit idling for hours sometimes. my mom when she could still drive would forget to shut her pontiac off after coming home and next day it would either still be running or just ran out of gas!!!lincoln 125spmonkey wards 250 ac/dcmiller 211 w/spool gunahp 200 sx tiglotos ltp5000dof course duramax diesel

Reply:No, not "IN" the oil cooler, but rather heating the coolant AT the oil cooler. And the reason is that you want the oil that's about to be sent to the Injectors to be ready to move more easily. Heating the coolant isn't doing all that much for you (other than creating a heat mass for the oil coming from the pan). I'm tellin' ya, it All About the Oil...Worn injectors are first diagnosed (again, starts @200K) when cold start problems first appear and when plugging-in for a couple of hours cures the problem it's Not about the warm Coolant

Reply:Thanks for the help ronsii!Diesels like you be warm and dont like to be ran cold. Dont wanna wait for it to warm up. That just me. I dont drive like a pu$$y and use the clutch so when not using it it needs to be revved up more which needs a warmer engine to do so. Block heater works so good you can have your heater on right away. Combustion chamber still takes time to warm up tho but you can take off right after starting it and keep it in a lower gear at a lower rpm to warm up. Not trying to argue these are just how I do it

Reply:John still mad
Reply:Don't know if John's mad but I still believe your thinking is skewed awfully bad with non use of the clutch. The tranny in your pickup is NOT a road ranger and I doubt you'll ever learn to use the throttle properly while shifting.

When all of a sudden it went woosh. lol And the really neat thing was that it blew both sides of the cork pan gasket out and onto the ground, not really hurt other than the cut out from the bolts. I started and used the IH to pull start a Ford car and then shut it off before I ran out of oil. Basically I learned to be a bit more cautious when heating the oil pan.
Reply:Takes 5 minutes idling and 6 minutes driving to reach the temp the block heater put into the motor. So 11 minutes and lots of diesel saved when having the truck plugged in for at least 3-4 hours, I actually leave it in longer. I love it!!! Thats a pic this morning and temps in the 30s, thats the temp before starting the engine, right after starting at work and 11 minutes after leaving work it got to about same temp as what the block heater puts in the engine
Reply:Not sure if there were different wattages on different years of the 7.3's but I found 2 hours was about optimal for warming mine up on a 25-30deree morning so I put a timer on it to start the block heater 2 hours before I'd go down to start it... even then it would take a good 5-10 minutes at high 'chip' idle to get the windows deiced sometimes
If I ever have to go back to using it for daily commutes I am going to install one of those preheaters as you can plumb them into the oil and water systems... sure the one I linked to was only ...what... 5kw's on the btu calcs... but that's ~5Xmore than the block heater
and you can plumb it to the cab for heat to which would solve the deice on the window problem
...I'd probably get a mid range one anyways... or I could just build a garage for it??? or maybe buy a new truck... the boss was looking at upgrading the '19 ram 3500 the other day.... seems you can get a nice 'newer' loaded one for around $82k...

Reply:there, at one time as far as I know may still be around, a thing called a hot box. It operated on 12 volt and would connect to cooling system and heat the block using hot water. Didn't take long for it to heat a big cummins or cat powered road tractor. Just my 2 cents.

I've only broke two extension cords that way in 15 years. Another thing is to park with windshield facing east so the sun helps defrost windshield. Doesn't help if you have to leave before sunrise tho.

kind of down in a draw facing SW so right into the prevailing winds
and just about never gets any sunlight on it... unless I waited til' about noon
I need to replace the plug on it... again... there have been a few times where I get so busy loading up and getting things organized I 'kinda' forget it's plugged in
and drive off.... then when I get home to park I'll be looking in the mirror and see this yellow cord laying on the ground all stretched out... then it's hit me!!! DOH!!! did it again
