Eventually I'd like to finish our basement and add a woodburning stove there. To save costs on pipe as well as being able to tap into the chimney from upstairs at a later time, how much hastle am I looking at to do it myself and what recommendations do you have?
Not real sure how to anchor it to the house as well?
There are triple-wall chimney stove pipes and similar woodburning fireplaces that can be safely used with zero clearance with wood framing.
However, you cannot vent another woodburning fireplace or woodstove into the same flue of another due to backdraft.
Normally, unless you are very experienced at it, fireplace chimney work is not a DIY job. Doing it incorrectly is far too dangerous of a fire hazard. You may void your homeowner's insurance if you have a fire, not to mention killing your family or yourself.
Plus you need a permit and inspection, and the local Buildign Inspection Department may not allow DIY work on this.
