Last winter was milder and I left the wall tent up from fall to spring. It is relaxing to just go out there with a nice woman and some dogs and build a fire.
I am like ppine, only Jake and I are the only ones in the tent ... my wife is not a winter person and will not entertain this idea.
I keep my Snowtrekker 8x10 Basecamp up from early January until around April. Jake and I hike in the timber and mess about like 5 - 7 days a week. After a good long hike, we visit the tent for a rest, warm up with a fire, make a hot drink ... maybe I read my book and he takes a snooze. I process firewood, then we continue to hike home. I posted pics of this on a thread called hot tents ( Tents, Tarps and Hammocks forum ).
My Kni-co tent stove is called the Trekker and is great, but I think could be a bit larger when it gets cold for real. I have struggled with using a damper as it is such a tight fit in the stove when traveling and even when dealing with well seasoned wood it would leave my fire box smoldering. It would smoke in the tent, not put out a lot of heat ... it just does not work well. Burning without the damper and the stove has excellent draw, but on really cold days, the heat went up the pipes and the stove ate wood really fast - getting maybe 30 - 45 minute burn and the heat seems to be all or noting, to hard to regulate, tent would be a sauna or cold.
This year I am trying a slide in type damper I that made. It packs well, much easier to transport than the old butterfly cast iron damper, and does allow my stove to breathe better as well as hold back heat in the fire box. It is 22 gauge steel, 2 1/2 inches wide and 5 inches long. This is for a 4 inch stove pipe. The gasses/fire still have room to be drawn up the pipe, but is greatly restricted. I get good heat hold back, but no smothering of my fire or coals. So far I get about an hour to an hour and a half burn time, but have not packed it full as it just gets too hot with these moderate temps we have had lately, ( I suspect in colder weather I will burn hotter so more wood may not mean a longer burn). However, with the slide damper I made, I can back the stove air intake down to get a longer burn and more heat. That said, I have not used it in real cold weather yet ... as we have not had a lot of cold weather since the tent has been up. So far it works great but will reserve judgement until we get serious winter weather to evaluate it by.

Will my new damper work well or not - well if it does not I will figure something out. The point is when not canoeing, Jake and I love to still get out and walk around. Having a comfy place to rest and warm up ... even on a wet rainy day like this one, is really nice. My tent really is a base camp and having a warm stove to relax in is a blessing, especially when it is out in the timber and no one else is around.
