Firstthank you for this forumand for any input received from my post. We have heated strictly with wood for almost ten yearsbut we have never installed a stove or piping ourselvesonly cleaned the pipes. Our tiny home of three years is heated by our wood stove. We do not have any other alternative heat sourcenor a furnace. Friends built the addition to our home and installed our stove a little over three years ago. We clean the pipe with a chimney brush monthly from September through May. The past few dayscreosote is running down the outside of the pipe that is inside the housebetween the ceiling and the stove. The exterior pipe looks fine. Alsothis fall we had resealed around the pipe where it meets the roof. I appreciate your thoughts and suggestions to help us figure out what is going on.
. He is a bit fanatical about creosote since going through a chimney fire in a two story home we had rented many years ago. That system was not built correctly and it was not a good experience.
hh: Creosote is the condensation of moisture and volitile gasespieces and stove cast-offs. This usually occurs when the stack is too cool or the air movement is too slowor a combination of both. Sometimes folk try and save a buckrun single wall pipe to the rectangle (that's a thimbleand figure they can continue up through the roof. What happens is the hot gases hit that shocking cold attic point and it acts like a chillerinstant cool down. The pipe can be single wallbut should be Class A double wallor in some cases thriple wall there after. This allows the pipe to retain more heat and move the gasses up. That's about as general as I can get.
! and we've used it like this for nearly three years. And the top of the single walled pipe is disintegrating and bentperhaps from all the pressure when cleaning the chimney?
