Martin,

Very interesting - thanks. Following comments are to the topic of heat in tents, not a reply to your post:

I have seen more than my fair share of tent fires (canvas) in the far North, some of which involved fatalities(s). But all things considered, less tent fires than I would expect under the circumstances.

I do not disagree with a general sentiment that generally says that most of us will never NEED to have a fuel burning appliance inside a tent. Having written that, there ARE circumstances and locations where cooking and/or heating has to happen inside a tent. Unless, of course, we all move to the tropics and never vacation in the high mountains or far North (or far South, globally speaking).

So... now that we've all thrashed the "No Flames in Tents" concept pretty well, maybe it's time for some discussion of when it is appropriate and how to minimize the risks. It doesn't have to be -40 deg with horizonatal blowing snow situations - there can be life-threatening situations in much milder conditions where heat in a tent is appropriate.

<shrug> Or I can keep biting my tongue, I guess. "No Flames in Tents" probably applies all the time to 90% of us here anyway.

Regards,

Tom
