I think what Mike meant was that if you have idle or no idle the stack temps will be the same if you have good gasification. Which will still give me low temps at the top of my 27' chimney. I have about 5 feet of pipe in the house and then a 90 outside and about 27' up. By the time it gets up there things are cooled down too much.
No screen. Long narrow slots all the way around. The creosote can build up to the point I am not comfortable with it. So I go up and clean it. No big deal. Seems like I remember seeing a unit you could buy and install on chimney that would keep the stack temperature up higher. Don't know how much electricity it would use. Doubt I would ever do that. I will have to look for it when I get a chance. Gotta go.
Agree that kind of unit would kind of defeat the purpose of burning wood in the first place...much easier to keep an eye on it and clean it.
Let me clarify with what I meant...If you idle excessivly there is no way you get "good gasification" all the time because you are starting and stopping the process meaning that you are sending unburnt smoke up the chimney at low temperatures causeing creosote buildup. If you are starting and stopping the gasification process your stack temperatures will go hot and cold even though you are reaching a max temp of 350* In-turn all caused by idling.
