Just wondering what you guys think about an extension on the stack of your boilers. Around me it's about 50/50 if they put one on or not. Does it help or hurt the efficiency of the stove.

Most stoves are designed to work well with what comes on them from factory.

Some of ur natural draft stoves may benefit from a taller stsck, no one answer will cover it all

If it's a well insulated chimney extension, then it's probably going to be alright.  If it's not insulated, creosote will build up in it quicker than a short stack and may not as easily light off and burn up thus clearing out the chimney again.  I would say that if you're going to extend it, make sure it can handle the creosote burning off fairly often.

I agree with scott on it improving natural draft stoves. My stove is fan forced 65cfm and is actually worse efficiency when I add my 4ft insulated extension. If your stove has a 100+ cfm fan I would say it shouldn't make much of a difference.

well as a high stack owner here…. Being high doesn't not hurt the stove esp being forced draft ..Natural daft I would think work better..It would get that fire going faster..Besides its recommend/law in some state to add the pipe if you have neighbors
