I saw a picture of a canister stove where its carry pack was used as a tent heater (while you are a wake of course) but can not find the company who made it, anyone know?

Bad idea even if you are awake. If the tent is sealed up, awake could easily become not awake-ever.

You know nylon melts in an instant, I hope. And those synthetics we wear will melt to our skin quite painfully. All it would take is getting a heater too close...

I see tent heaters from time to time... never used one. I might use a small stove, very very carefully, in a vestibule, but never inside the tent. That would be a really bad idea. Look up carbon monoxide and how poisonous it is to understand why.

+ 3 here for no, no, no:

Nylon tents melt. Silnylon tents are not fireproof. Not only that, but the melting nylon will stick to your flesh and keep burning. You don't even want to pitch one close to a campfire (if nothing else, sparks will melt holes!).

Nearly all canister stoves produce quite a bit of carbon monoxide when burning. They should always be used in a well ventilated area, not in the tent.

Instead, use a warmer sleeping pad, warmer sleeping bag, warm clothing worn inside the bag.

For that matter, heating your tent with a canister is a waste. All you need to do is keep that small space right next to your body, and any others in the tent, nice and warm. That is what good clothing and sleeping bags are for. The other posters are absolutely right about the dangers of carbon mooxide and melting nylon.

One here for maybe...
Seriously folks, theres been a lot of hype about carbon monoxide. A couple of facts:
1) Carbon monoxide poisoning is cumulative. It takes about 2 weeks for your body to replace the hemoglobin destroyed by carbon monoxide, and consequently over 2 weeks too much carbon monoxide kills you. Meaning it might be ok for 4 nights but 6 might kill you...
2) A properly burning flame that is not somehow cooled before it finishes complete combustion, does not produce carbon monoxide, it produces carbon dioxide. The carbon obviously first combines with one oxygen to form carbon monoxide, then it combines with another oxygen a bit higher up the flame, to produce carbon dioxide. You do not want to interupt the complete oxidation. (I believe it was an Australian climbers group that said to raise your pan support one inch to make stoves safe to use in snow caves and tents.)
3) Climbers and many winter people must cook and have stoves in their tents and for instance I have a Bibler hanging cannister stove designed to hang from the crossed poles at the top of my Bibler Eldorado tent. Stories of people dying from carbo monoxide poisoning in tents are rare, but it happens a lot in trailers and truck campers.
4) Homeless people have a coffee can inverted over a propane flame to gently warm their tents with infra-red. As long as the can doesn't intefere with the flame (and cool it prior to completed combustion), its just a contained hot air column.
5) You may notice that the OP only asked for help identifying something and did not really ask for anyones opinion on the subject.
6) Its probably European twinmike, you can buy a greater variety of items with fewer "safety restrictions" there than in America where we are protected from having to decide to not buy things bad for us , like tents that might burn with a blow torch on them. You cannot even sell a nylon tent in California that will sustain a flame. If you want a tent made of superior materials and you live in California, it is illegal to purchase it out of state and have it shipped in because a California child could burn up in it.

So ok yeh sure - gee don't ever light a fire in a tent ok? its not safe, but besides that, people do it all the time. Anyway don't do it and die and say you did it because I said so. Anyone who takes advice from the Internet about life threatening activities is crazy. Get profesional training, or talk to a homelelss person.
Jim YMMV

I would bet that we have all done some cooking in our tents but it is a dicey practice and should be done very carefully and quickly. I have had enough experiences with CO over the years such that I am much more cautious than I used to be in my flaming youth. It is insidious and can kill or disable quickly.

HYOH. Be careful out there and enjoy the fresh breezes......

I dunno, I haven't noticed anyone having trouble getting any kind of tent they want here... Tents in stores are largely PU coated but more and more major mfrs are making flies out of silnylon and selling them at REI. And no one has any trouble ordering from out of state.

And Tarptents (although manufactured in Seattle) are sold in California!

The native's did it for centuries, but then they knew what they were doing back then. I personally would prefer starving over some serious burns.
The are tents designed for stoves but I'm sure there is a weight factor involved.

I half way agree with Mr. Shaw. Back when I was a ground dweller I carried a candle lantern in cooler weather to take the chill off the morning air in my tent.

In my opinion there are only two semi-safe ways to have combustion in your tent. One is a floorless tent and the other is a hanging stove. I have used a Kifaru stove in a floorless tipi and the MSR hanging stove.

A tent must be vented to minimize condensation. A properly vented tent will not likely have CO problems, unless the air circulation is blocked by snow, etc.

Bumping into a hanging stove/lantern IS a problem. Any combustion supported by a tent floor is NOT acceptable.
