Hmmm I wonder how well this would work in a tent? DIY Heater

Two issues...
Fire hazzard...open flames in a nylon tent.
Carbon Monoxide poisoning...it happens.

Interesting concept but I'm not so sure I'd want to rely on that at -35 degrees with wind.

Hell no. Don't use something without some kind of high-CO/low-O2 sensor and auto-shutoff in an enclosed space.

Would you consider a Timberline an enclosed space? Doesn't seem possible for it to accumulate dangerous levels of co2.

Count me as a skeptic. Please explain the physics behind a candle in a flower pot producing more heat than a candle in a lantern? BTUs are BTUs. I suppose that the heat is radiated differently but would it "feel" warmer? I doubt it.

Why not simple use a hot water bottle instead? Much simpler, safer and effective. Just my $0.02

Ya I have no idea if this would even work but always looking for neat, new, safe ways to heat up a tent :)

I will take a stab at explaining it to you...
It doesn't try to heat the AIR, it is heating the pots and is better able to retain that heat. the pot is then "radiating" that heat to you. Google the term but think of it how the sun gets the heat to the earth. Holding your hands around the pots would heat you way more than holding your hands around the candle...IMHO.
As far as the CO thing, it would be a much more gradual thing but yes, people have died from it in tents...and no, I can't site a specific case. I am just not that interested to Google it.

I have used candles in the tent for years (non-BWCA). In my experience, a couple of small candles in the apothecary jars put out enough heat to take the chill off down to the 30's. Plus you get that psychological comfort of a mini-campfire.

Actually, I am a physicist and understand the basics of thermodynamics. I am just skeptical that it would feel different than a candle lantern considering the small amount of BTUs given off. Instead of conducting the experiment myself, I'll just wait for mythbusters to disprove it :)

IMHO The laws of thermodynamics are the same for everyone. A candle will produce the same amount of BTU's wither there is a pot involved or not. The only way the pot will make you warmer is in the BTU's you will make carrying the extra weight around. The pot just slows / stores heat.

They do make a 3 candle candle lantern where the top of it will keep your coffee hot on it. From my experience in a small tent (a tent you have to crawl in and out of, and barely sit up in, double wall /no netting.) or snow shelter it produces enough heat that you can notice when it is not lit.

He fit like a dozen candles in that thing...and someone with your background shouldn't have needed to ask. Light reading material.

Wow Doughboy..why the antagonistic response? You really seem to have a chip on your shoulder. I am sure if you re-read my post you will see that my point was easy enough to understand.

I won't waste my time debating you or letting you turn this thread into something it isn't.

I'm recalling a Star Trek episode where they were stuck on a cold planet and phased some rocks for heat. So one tent heats the rocks or clay pot and the other just heats the air which quickly vents. Same heat energy but seems the pot keeps more in the tent longer. Or just blast the phaser into the air and see how that works. Or call Scotty and tell him to warm the place up.

That's it! I am definitely bringing my phaser on my next trip! Lightweight plus would be a great bear deterrent.(set on stun, of course) Hey I notice spellcheck has no spelling for a phaser. What's up with that? :)

Yep, same thing as those trendy patio heaters. They are NOT heating the air around the patio.
They are transferring the heat to you by RADIATION.
The link I posted was meant to explain not excite.

The idea of nearly instant boiling water is appealing. Now if it could also do the reverse and make a (plastic) bottle of beer instantly ice cold. Wow - would that inventor get rich.

More seriously - all this talk of hot tenting makes me want to try it. Where can one rent this stuff in the greater Chicago region?

Flame inside a tent without some sort of exhaust is asking for trouble. Hot tents have a stove pipe to exhaust combustion by-products like CO.

I ike the idea of the candle heater wish somebody can tell if they actually tried it for real. Otherwise get on of these heaters Heater

We already take it. Work very well, in the cold weather i test in and write here a review.
