Hi all, new to the forum, however not new to wood stoves. I recently purchased a used Super 27, built in 2001 and installed it into my home. We had a 25 year old Country before. With the older stove, it would not keep the house warm enough, but we rarely had to clean the stove pipe. We would clean it once a year for safety sake, but it did not display signs of over creosoting. With the new (used) stove, we have had to clean it after a few months and the 6" stove pipe was completely clogged. The stove pipe consists of 6' of uninsulated stove pipe to the ceiling, then it passes through the ceiling into the second "half" story. From there, it goes into insulated pipe for 4' and then passes through the ceiling/roof. On top of the roof are 2 4' sections of insulated stove pipe and into a chimney cap. The cap is above the roof line of the house. It is extremely hard to clean, because you have to take the roof top sections apart in order to get a brush down the pipe. (steep roof, tall pipe) We live in the PNW, so we burn primarily Doug Fir and larch. We really like the new heat output of the stove, but despise the excessive creosote issues. Any ideas on what is going on? The new efficient stove probably keeps the stove pipe cooler, so in turn we get more build-up, however this current set-up is not working. Thanks for any input.
