Question: I have a chimney and flue in my basement- which is around 800 sq ft. My first floor is also 800 sq. ft and my top floor- which shares some cathedral ceiling space with the first- is 400 sq. ft. (2000 sq. ft. total floor space). I would like to have the ability to burn anything in my stove- but it seems that there are very few (if any) manufacturers that carry such a device. A:No such thing..the closest is a wood/coal unit made by Harmon Stoves. It's pretty good on both fuels I live in the Poconos Mountains area of Pennsylvania. Good firewood is easy to come by- for $100 a cord for seasoned oak. Coal is also relatively cheap and easily available- and I am told that our coal (from the Lehigh area) is some of the most efficiently burning stuff around. Pellets can be bought at the local hardware store. Can I find a stove that will burn all of the above? A:Try the Harman--there may be some others. Stoves and Stuff (they have 4 stores including one in Stroudsburg) are a good source--I've known the owner for 10 years! My goal is to at least heat the basement and first floors of my home. I am in the process of converting my basement into living space for my mother in law- so it would be an added benefit if the stove is easy to operate. I have reservations about purchasing a stove that relies upon electricity for operation- like the worm drive feeders on some pellet stoves. I would prefer one that CAN use electricity but will suffer no damage or loss of efficiency if electric is not used. A: I'd advise against pellet stoves cause of electric use...the Wood or Wood coal option would be best I I had a woodstove flue built into my chimney and am know ready to add a free standing woodstove. the flue is in the concrete block wall in a room that I am finishing. I need to get any info. i can on the construction of the wall behind the stove. What wall material is acceptable. Do you construct the wall the same as any other wall (i.e.- wood studs) or is there some other way to attach the wallboard (is it duraboard?) to the block wall ? Any information and resources you can identify would be helpful. Answer: Some answers are above in between your question lines..in addition: The clearances are different for each brand of stove- some can be put close to a wall with no protection on the wall- others must be further. The most critical part is bringing the chimney thru the frame wall -- most chimneys I have seen are constructed wrong- that is the crock (ceramic terra cotta)- is too close to combustibles where it passes thru the wall. Either a piece of insulated pipe or special designed "thimble" should be used (ask your local retailer)- or a large "masonry wall patch" should be built around the crock where it passes thru the wall. As far as wall protection- most of it must be spaced 1" off the original wall. The clearance reduction is then approx 50% (from the normal specs).possible materials includes: Sheet Metal Dura Rock Brick or stone Pre-Made Stoveboards.
