First time poster here so be gentle... I am trying to add a wood burning stove to my walk-out basement as supplemental and emergency backup heat. The basement is unconditioned and mostly unfinished... the walls exposed on the walk-out side are insulated. I am located just east of Atlanta, Georgia, so heating needs are low relative to more northern climates. My goal is to install a passive (non-blower) high efficiency wood burning stove(like the large Kuuma Sauna Stove), so I can heat the basement on an "as needed" basis and allow any excess heat to "drift" upstairs and supplement the heating on the main floor. My house is 5 years old and very well insulated. Here is my current situation... I have a Superior BR-42-2 "builder grade" fireplace on the main floor that we do not use or intend to use. I hate the inefficiency and mess of standard wood burning fireplaces…the fireplace has a Chimney Pillow inflated above the damper to seal the 8” metal chimney pipe. I assume it is a single wall metal flue, but cannot confirm at this time. The chase for the fireplace is located inside the house envelope until it penetrates the ceiling into the unconditioned attic space and continues on through the roof. I already asked my wife about removing the fireplace and using the chimney stack from it, but that was a “no-go”. Locating the stove in the area under the fireplace is the ideal spot for heating the basement. Here is a quick sketch of what I have now. I would appreciate any ideas as to the best ways to approach this. I am a bang for the buck value guy, so don’t assume an unlimited budget… Thanks in advance.
