Ha ha, my apologies, I think I might have posted some picks in the picture of the day thread, but I'll redo them here. I've used it twice for overnighters now, both times the temperature was between -15 an -20 C, so around 5 to -4 F. I built a little box to get the stove up higher for the second trip, prevented some snow melt.
Had to feed it every hour/hour and a half overnight to keep my wife toasty. The first time, I didn't use the in-pipe damper, just the one on the stove. This made for a fairly efficient burn, no creosote build up in the pipes. The next time I used the in-pipe damper and did not like the overall results. It slowed the burn down too much, and lots of creosote in the pipes resulted. As well, the coals never fully combusted, so the stove filled up overnight, it was hard to get more wood in. There is a tool that comes with it to scrape coals out during the burn, next time I am going to do that before the evening, scrape the coals out into a shovel and toss them outside. The glass window is not airtight, I am going to have to fix that or use the other door I have that has no glass.
All in all, I think it is a great little stove, my favourite one at the moment. The stove is robust, stainless steel and a quality build. It will last for a long time. Pretty sure we would be comfortable down to -40 in there with this stove, the insulated ice pop up tents are a thing of beauty, if you are not worried about weight. The stove with all the accessories is not lightweight either, I keep everything in an old hockey bag, probably comes in around 25 pounds or so.
Obviously, we weren't worried about weight. I had my skidoo with two sleighs to get everything out there.
It was about -20 when this pic was taken.
I dried out the tent and put it away a couple of days ago, we still have lots of ice, but the weather is sketchy right now, got 12 inches of snow on Wednesday, after a week of solid melting, so the lakes will probably be slushy. Opening weekend for walleye is the middle of May. It can often get pretty cold then as well. We are planning on going out then, if it is going to be cold, we will take the same set up.
There are other similar stoves out there being offered on amazon, built in China, but for the hundred bucks you might save, I would go with something that is built to last.
