Coleman Lantern-BTU’S?

[hawg]

I went out to my 8x16 fish house yesterday. It was 21 below when I got there and lit my 20,000 btu direct vent heater. It usually takes the time it takes to drill my holes to get warm enough to be sweating when holes are drilled and skimmed. At the last minute before leaving home I grabbed my propane Coleman lantern that had been hanging, unused, in my garage for at least 10-15 years. I figured the extra heat boost might help, couldn’t hurt. It started up first try, and then came the old familiar hiss. I was shocked at how much heat came off it even though I used it to heat my old poorly insulated 6x8 house. It still took almost 2 hours to get up to 50 degrees in the house! Does anybody know the btu rating on the lantern, if there even is one?  It was really relaxing and nostalgic hearing and watching that old lantern.

Dont quote me on this but i think its around 1700 btu for a 2 mantle white gas lantern.

Did a quick google search on this topic - most sites say that the output is around 1500 - 1700 watts which would be about 4000 - 5000 btu's.  There are even some old Shanty posts on this from 2008. 

It always amazes me when doing a search that the first post that comes up - is something from the Shanty!

Im not arguing but that btu seems high.i know the best coleman lantern is the dual fuel and it says 2400btu on the box.i do not believe any lantern has the same btu as a little buddy heater.i use both and the little buddy gets my flipover warm where i have to shut it off.lantern just stays lit.

True - read your post and then looked it up.  Seems that there is a few different ratings and so not really sure which one it is.  With a btu being 3.41 times a watt - that is what I was thinking about.  Trying to find something that makes sense. 

I always try to regulate it to a lightbulb.  Does it make more sense to think about how much heat comes off a 100 w bulb and then I look at it. 

Will keep looking into this.

I've warmed my hands many times over a Coleman lantern; first white gas then LP. Even enough in a small tent, like a one man flip, to make a difference. I know, it's not a hard value, just brought back memories.

I have heated many shanty’s with a single mantel Coleman lantern always with Coleman fuel never gas...

A double mantle white gas lantern is all I use in my otter lodge.

I use to run the dual fuel lantern too about 1500 btu listed.  Also have the dual fuel stove and it's same base with 1500 btu listed too.

Then I the old catalyst single propane heater at 1500 btu also.

Tomorrow is supposed to be -15 w/ 15 mph wind. So much for nostalgia, I’m taking the big buddy!

Just a short follow up. I took the big buddy out, it was -19° when I arrived. I fired the buddy up and I couldn’t believe how fast that house heated up. It wasn’t more than about 20 minutes before I had to take it down off of high, another 15 for medium, and by then the house was up to about 60° with the wall-mounted furnace. The problem came when I left. It’s been so long since I’ve used a non-vented heater that I forgot to leave the door open to get the moisture out before I left. The next day I came back, again at about -19 below zero, and the door lock was frozen so solid that I couldn’t turn the knob. I could get the key in but the knob wouldn’t turn. It took me about 10 minutes with a torch that got the door knob so hot that I can hardly hang onto it with gloves to get that thing to turn and it was still tough. I won’t make that mistake again. Good news is that the fishing was great👍..

Like someone else said heated many shanties with them.
Years ago that what was used for portable heat.
We also walked through 6’ of snow and it was uphill walking both ways the the shack.

Please don't forget the CO dangers when using these white gas lanterns.

im betting there will be several more than usual cases of this, with all the noobs out there now.
