I always plugged mine overnight when it got real cold out. I always leave my vehicles plugged at work even when not that cold, no reason not to.
I didn't like paying for electric full time.
It takes longer than 2 hours to heat up a DT 466 when it was -5 last night. It's kicking but not starting yet, 15 more minutes I'm hoping.

never plug either of mine in (have to cycle the key once in a while)Dont see why you couldnt leave them plugged in 24/7, its a low wattage heater so no boiling should occur.
If you did plug one in the only reson I can see for unplugging it would be save on the electric bill and to prevent pulling the socket out of the wall when you drive away which for me is teh biggest reason not to plug one in, 
There are breakaway connections made just to prevent such a thing from happening.

My M715 is plugged in to a timer
Cool deal, it bothers me when it's plugged in for more than like 12-24 hours. But then when it's this cold I'd be good for any amount of time just as long as the the truck starts. lol
I did not get through the day trouble free, one of my trucks air dryer purge valve froze up and would not build air. Even with me on my back under the truck in the middle of the road with a hand held trigger torch with map gas in the tank. I put a lot of heat into the dryer but the purge valve would not close. Had to have the truck towed back to the shop and it's inside thawing out right now. Luckily this happened at 4 PM after the truck ran for 9 hours and we got most of our work done for the day. The air temp was and is dropping hard right now. Not uncommon at all to see freeze ups at sun set when its getting really cold.
I just got here about a 1/2 hour ago and I just got back to the shop. I was outside all day today since 5:30 am.
I just got back from the parts house with a new purge valve/heater and a whole new dryer. I usually keep them here, I got "caught with my pants down" Not sure which I'm going to replace yet. It's gonna get done here in the next hour or so. The truck has to run tomorrow and the next. I do whatever whenever it takes to keep them going...for 30 years now.

I put mine on a timer. Saves on electric bill, plus warms oil so it saves on engine wear. Cant plug in at work and she starts fine. Like I say, do you jump out of bed and hit the ground running ? I don't I like to have a cup of coffee and then get moving. The truck is no difference, cranks nice, warms faster. I swear the grille smiles at me for it ! lol

Most block heaters will do about 80% in 1-1.5 hrs. IMHO if it won't go at 80%, it ain't going anyway.
I don't usually plug in my N14 Cummins until it gets to single digits and it fires right up no arguments after about an hour. I have fired it unaided at -15 but it makes quite a fuss.
If I might suggest Gary, maybe check the current draw on the starter on that DT. At -5, in my experience it should have fired albeit with some difficulty unaided. Plugged in for an hour it should have fired like you just shut it off. It is only 466 cubes.
I think you might find that the starter is drawing a good bit north of 200 amps.

I hear you, and can check it. Got one right in front of me right now in the shop. but I can pretty much guarantee you that none of my DTs would start without being plugged in at -5°. They haven't since 1985 when we got our first DT and not even new.
The new electronic DTs with the hi pressure oil pump will not start in the cold. Our old mechanical DTs maybe. That's been my experience with them?

Makes sense. Those HEUI engines need cranking speed to make oil pressure to inject with.
Have you considered a Webasto diesel fired engine heater?

My CRD Liberty I leave plugged in over night, and basically whenever I know Im gonna need it, every day LOL Why not? easier on the starter, battery, fuel system, and everything likes to work better a little wormed up. I know I do. My 91 Cummins started at -20 a few years ago as I didn't know the block heater cord had an open in it. I fixed that and it started a lot easier from there on. Seems silly not to plug them in to me.

Most around here have went to Espar heaters. We're finding they heat longer on less fuel and are lasting longer.

I don't think there is any question that an engine starts easier plugged in.
I think the question is, does it need to be plugged in continuously and I would say that in most cases the answer is no. If you leave for work at 7AM every morning, put it on a timer to come on at 5:30 and it will start the same as if it was on all night.
If it is a randomly used second vehicle, you could just put it on a timer that runs 20 min per hour which would be good in all but the coldest weather (like -40ish) or just plug it in about a 1/2 hour before you want to leave.
A 1000w heater uses a noticeable amount of power on your electric bill $$.
