Wood Stove Rear Flue Exit?

[Jafo]

Oh and using 2 45's instead of a 90 is good advice too. I did this with my new stuff and it was a big improvement.

That is a tough question. Our straight out the back stove pipe was from a wood cook stove which did NOT draft very well, but it's like comparing apples and oranges; cook stove to regular wood stove. One advantage I liked with the S.O.T.B. method was the clean-out of the portion of the stove pipe inside the house was very easy. You can just reach your arm all the way in from the clean out access in the T outside the yurt wall.



On our double 90º stove pipe we actually have to disassemble the interior pipe once per year in order to clean out. Very messy and a lot more work, but I *think* it drafts better. Although it does smoke a lot when we open the door to add wood.

'Although it does smoke a lot when we open the door to add wood.' Have you tried opening the damper before opening the door to load?

[Jafo]

Also, I found that if the

dome

is open at all, it lets more smoke in when I open the stove. Most of the time no smoke comes out when the stove is hot.

We even crack to door to let it start burning really hot before adding wood. This does help, but I think the two 90's are probably to blame. We also open a window first or close the

dome

. Try to change the pressures... Oh and we have fresh air intakes in the floor as well AND a very long insulated chimney.



Do yurt people actually have wood stoves that DON'T smoke when you add wood? I had kind of given up on the possibility...

Takes a while to learn how to run your stove. I have an old 80s era air tight stove in the center of the yurt, with a pipe that runs straight shot from top of stove up through the ring. It just doesn't get any better than that in terms of draw.

I load the stove through the front by opening double glass doors. When adding wood to a cool stove that's been running damped down to low, with both doors and the flue damper closed, I open the damper, then crack open the doors and let the fire wake up a bit. That would pretty much eliminate smoke entering the yurt when the doors were fully opened to load., unless the wood was damp from rain or snow.

When stoking the stove running hot, doors open, damper open, even damp snow covered or rain soaked wood generally didn't smoke the yurt. Plus I'd get maximum heat. If it did smoke inside a bit, partly closing the doors would increase the draw and get the smoke drawing back inside, and get damp wood to blazing. Took awhile to learn how to run the stove so it didn't smoke.

Another thing, all three of my yurts were drafty. Lack of air flowing into the stove from a tight yurt wasn't a problem. lol If my yurt was primary dwelling, I would have an exterior air supply piped into the box, just like I do for the fireplace in our house.

Hello , first off heat is omni diertional, but not straight up, it will always go to the cold and most likely you have already proven that, when you sit at the campfire you feel the heat even tho you do not sit right ontop of it the ground under the fire is warm as well, now that out of the way the out the back was created because some people think stove pipe are ugly to look at , and you have more cook surface on top with the vent in back but you can take it straight out the yurt wall to your T, or if you want more heat bring it up above the stove, and then out the wall, it will not matter, just what ever you like but if you bring it up then you can get one of those fan for the pipe to push more warm air in the ger/yurt, but remeber its your yurt and what ever you decide is the correct way,


enjoy your ger/yurt

You are confusing heated air (draft) with radiant heat. Hot air rises.

Jafo how does hot air move or radait out from a fire heat always goes to the cold and it does not care how it gets there up down looped to looped heat period will always go to the cold, unless you send it by some means
