Question about H45 heater for M1101 camper conversion

I own an M1101 with fiberglass cap. I also just rediscovered my H45 type II that uses Diesel fuel. Is this heater too big or will it adapt to working in a smaller camper style M1101? If too big, perhaps I should attach a tent to the rear hatch of the camper? Should I consider an SHS small unit instead?

Thanks in Advance

my understanding is that fire starter... ahhh I mean heater will put out significantly too much heat for habitat on back of truck. There is a much smaller version made by Hunter you can find. Most you find by Hunter is the "Arctic version" and it too may be way to much heat. Both the later Hunter versions the oil burn controller is supposedly way more efficient. BTW..... think their is a forum in here where these heaters are discussed.

IMHO your best bet is a china diesel air heater.

I see this but I don’t see a true camping forum or heater forum…. I guess I will look harder. Thanks!

above long predates the RV forum.. this is a very new forum on the SS discussion board..... and most loosely Military of all the forums in here... understandable since it is an offshoot military-ish project forum among the Military Vehicle restoration-ish forums that makes up the main crux of this Discussion board.

Seems like I could heat a building with this bad boy.

I guess I’ll keep it for power outage Winter emergencies.

That would roast you in the trailer....
Fumes and exhaust also not ideal...
I have one that I use outside and it gets hot now I do have a different idea of what cold is down here than NY 🤪

You might look at Mr Heater.
Different ones and uses small propane bottles

Ok,

The Army was not always the civilized organization it is now. Back in 1974, it was much Closer to a "Hell on Wheels" thing. The consumption of drugs, beer and strong Spirits was a thing of wonder.

I was in a HAWK TRIAD Battery. We had a 7 day field exercise. The training areas were all within 30-50 klicks from Bamberg. On the average an ADA unit used to move every 6-8 hours. A stressful operation. I was a part of AFP II, Assault Firing Platoon 2, about 30 people max.

Part of our Basic Load was several cases of beer, and of course, Numerus bottles of El Rojo Tequila. But, sad to say, all good things come to an end. After the 5th day, the cupboard was almost dry. We were in a location called Area Mike, but we called it Area Mud, and with good reason. We were more or less trapped in a sea of mud, and nothing short of deine intervention was going to get us out of the site.

The Platoon LT called the whole show off and we stood down. A few of us enlisted types had a small confab. It was decided we would put up the GP Medium tent, and sleep under canvas for the first time in a week. It was also decided that we needed to organize a resupply mission. After consuming all our meager booze supplies, we hiked off to the town, (really a village) called Sulzheim, outside of Schweinfurt. Takes about 30 min to get there.

We were "well known" in town. This was not our first time around. There was a small Gasthouse that sold us the needed 6 cases of beer and 3 bottles of some type of schnapps that tasted like swamp water. We hiked back to the training area and went to the tent. The LT and NCO's had a tent about 30 meters from ours. I have no doubt they heard us come back.

After making a dent in the resupplied booze stock, someone had the great idea to get the stove out, and "Heat the tent". And so it happened. Since the fuel metering valve was dirty, it did not work well at all. We unhooked it, and we tossed in some dry wood, (tent stakes) to "help " things out. And then some more wood. We left the diesel hooked up, for some reason. Beer had nothing to do with it.

At some point in time, the tent started to get nice and warm. And the stove got nice and red. I love to fix things. So I took the fuel regulator apart and fixed it. Hooked it back up, and turned on the fuel. We all agreed that things were looking up, the tent was warm, and we did not need any more wood. Life is good!

We continued to reduce our stock of beer and bad schnapps. It got late, so we agreed to set up a fire guard watch, to make sure nothing happens, like the tent burns down, or that the stove went out. A few hours later, the ashes in the stove from the wood kept the oil from burning right. So the fire guard turned up the fuel. All the way. and went to sleep. Someone else woke up cold. He found the stove cold, so he assumed the fuel had run out. So he tossed in a bunch more tent stakes. And a half cup of denatured alcohol, to "get things going". Mean time the diesel was still turned on.

Well, the stove lit up. And started to get hot. And then the stove got red. By this time most of us were awake, as the Fire guard had become somewhat upset about the RED stove. Then the stove pipe started to get red. And the stove began to MOAN. Anyone asleep soon woke up. I turned off the regulator. But it was way too late.

So there stood a bunch of drunks, looking at the stove and pipe get ever higher red. I supose we all thought things were going to get better soon. Soon the tent hole where the pipe went out began to smoke. At that point SFC L. H. walked in asked us the 1000 dollar question. "What the **** is going on here? He sent us off to find a fire extinguisher. No easy task, as the elbow on the army fire extinguisher is just the right size to make a kick ass hash bowl. So it took a long while to find one that worked. By the time someone showed up, the tent was burning along just like a well fed bonfire.

The enlisted members of AFP II got to fill a lot of sand bags for the next several weeks.

Great story BUT that fire cannot be attributed to proper use of the H45.

I’ve decided that instead of purchasing outdoor propane heating hoods for my back yard, I will place the unit on the drywell grate and use this for Spring and Fall warmth. I’ll keep the required chemical grade fire extinguisher at the ready. I don’t endorse THC so I’m certain the extinguisher will be battle ready.

Back when I was frequenting FB I was a member in a "Chinese Diesel Heater" group. Honestly, you might look into researching them. A LOT of van life people swear by them (and that's about the right size). I have a Hunter blast furnace in my M1079 and it's not only too loud but it cooks the hab in about 2 seconds (it spends more time cooling itself off at shut down that it does actually heating air). I'm on the fence about ripping it out (as others have done) and replacing it with one of the little diesel units).

Lots of good articles on them out there:

I’m afraid that the Chinese diesel heaters breakdown and become noisy after several hours of use. They don’t seem to be as robust as we basto.

Will have to look out for that as I watch/read learn from others..... honestly have not seen much of any talk of that issue.
Read the Amazon reviews. They are full of complaints.

Additionally, there are a few YouTube comparison videos. The posters speak of fuel pump failures and such, but the posters seem as if they are in the back pocket of Webasto. The posters make some good points but overall seem biased against the Chinese units.

Anyone here is these Chinese made units?

If I trusted the Amazon reviews, I'd never purchase anything ever again.
"1 star: box was damaged in shipping"
"1 star: Item never arrived"
"1 star: China maidz teh COVIDz"

Hell, das uber-est-German Webasto units get just as CRAPPY reviews on Amazon.

But I get the hesitation. The reason I mentioned the FB group is because they go into good detail on how to improve on these little diesel units to make them safer and as reliable as the German-made versions with some very simple mods (mostly simple mounting improvements, etc). To each his own, and I had never really considered one of the Chinese units until I looked into them further.

But no, I do not have one yet. My Hunter sorta works for now (it goes into fault after about an hour of operation and pops it's cb). Factor in the fact that it's the loudest part of the truck (like a jet engine you can hear it over the CAT engine outside and even over the diesel genset when inside the hab, you will never sleep with this thing kicking on an off, forgget trying to watch TV or phone w/o headphones), the fact that it only runs for 30 seconds to heat, then spends five minuets blasting cold air as it cools the unit for shutdown, with the fact that it pops the cb after 30 minutes...and the OEM Hunter only gets 2 Amazon stars from my review.

My hab heat only gets turned on maybe three times a year, though. And one of those is only to make sure it still works.

ymmv

I appreciate your candor and insight. Thanks man

I just wonder who runs the FB site. Is the manufacturer or resellers or real people. LOL
It was mostly vanlife hippies.

LOL


Seriously, it was a user group. And it was filled with good insight. But there were troubleshooting groups, several user groups, UK groups, all solely for the little diesel heaters. I'm sure at least one is vender-owned.

The group I was a member of was specifically Chinese-made units and all user content.

Here is a TM 10-4500-200-13 for the M1941 (Grand Father of the H-45) and the M1950 Yukon stove. The M1941 is too big. The M1950 is smaller, but do not think its right for you. Uses Gasoline also. I don't know. Fire and gas? Never made sense to me.


The TM 9-4520-257-12&P is for your H-45. Thought you might like a digital copy.


TM10-4520-263-12&P, is for the Space Heater Small, (SHS). It a better fit for you, but may still be to big, in size.

WEIGHT:
SHS ............................................................................................................. 32 lbs (14.5 Kg)
DIMENSIONS:
Height ........................................................................................................... 17 in (43.2 cm)
Width .............................................................................................................. 9 in (22.9 cm)
Depth ......................................................................................................... 17.5 in (44.4 cm)



The TM 10-4520-261-12&P is for the Space Heater Arctic. Its a bit bigger and heaver then the SHS.

WEIGHT:
SHA..............................................................................................................41 lbs (18.6 Kg)
DIMENSIONS:
Height............................................................................................................ 17 in (43.2 cm)
Width............................................................................................................... 9 in (22.9 cm)
Depth.......................................................................................................... 17.5 in (44.4 cm)

Now you need to come up with a fool proof way to pipe the exhaust outside.
