Emergency Heater the H45

This is the first time using the H-45 Military Tent Heater. I got this as an emergency heat source in case I lose power this winter. It runs on various fuels and it does not need any electric. It outputs up to 45,000 btu of heat. This trial worked well. Tips: Instructions say to wait 3 to five min after you turn the fuel on, Also, tap and wiggle the line to force the air bubbles out. Put the full 4oz of diesel in the bottom of the burn chamber for the initial prime as the manual states. Any less and it may not start. Manual also says use one piece of tissue in the burn chamber. Found that two crumpled pieces of new paper worked better. Start it on high like it says and then turn it way down as soon as it starts. It will take about 2 or 3 min to calm down as the line is full of fuel. This fuel takes the few min to burn up. After that it will caml down nicely. The exhaust comming out the chimney should be nearly clear. It may be black at high settings. Experiment by turning it down slowly. You may get the same level of heat at a lower setting. It think the black exhaust is an indication that its buring rich. Disclamer: When using this inside, make sure its installed properly. Ensure the fuel line and source is per code and properly maintained. and USE A FIRE and CO DETECTOR!!! Please be safe!

USAwoody, the paper & fuel go into the inner burn chamber. There is the round hole on the very top of the unit. Swing the round door open, then carefully poor in the fuel, MAKE SURE UNIT IS COLD. Then crumple up the paper and put that on top. Hope that hepls. I would never start this thing with GASOLINE. It will create a big Puff of fire.

is there any specs on diesel usage per hour

[maginskyk]

@ttaylor667 The book states at full output, which is a lot of heat, the usage is .4 gal/hour. so it should be a bit more than 2hrs of full operation per gal. I have not tested this yet, waiting for winter and will know if this is an accurate number.

will this work with bio diesel or pure alcohol?

[maginskyk]

@d909kings Not sure? Issue would be the regulator. Its just a gravity feed unit so there is probably a pre-set needle valve in there. Would have to figure out the rate to let fuel in then see how well it would burn. Could be other problems? BE SAFE!

[maginskyk]

@d909kings Not sure about fuels other than what was stated. A bit of VERY CAUTIOUS research and experimentation would have to be done. Would have to check the flash temperature and the boiling point of the bio and alcohol and compare them to deisel and gas. If they are lower I would be cautions as it may explode. If they are higher may not work at all?

Where do you put the 4oz's of fuel?

[dLimboStick]

Those things do work real well. I went through Army Basic Training in March...still winter in New Jersey. Our bivouac got flooded. I woke up in 8 inches of water. The HQ tent had one of those heaters and let me tell you, they kick off some great heat.

Cool and informative. Thanks for posting.

Good demo. This would be a good liquid fuel stove and the M-41 would be the better wood burning stove as it has a 1/2" thick iron grate specifically designed to handle coal and wood..
