The other option for venting which a lot of people are doing with single chimneys is getting a power vent for their existing system so they can hook the coal stove to the chimney. The smaller stokers can be power vented too but it has to run constantly. Between the maintenance and the added expense of always running it doing it with a coal stoker is not worth it IMO.
I have an 1830's drafty farm house with the front being solid masonry with no insulation and the back being wood frame. I heat the beast with two stoves. The front has a vermont Castings resolute woodbutner and the back has a vermont Castings Vigilant II. I can keep the place warm even when the temp drops to single digits and since the insulation is so poor the coal can keep running until the end of March or the middle of April or until the temp is consistantly above 55 degrees. Coal is great for long cold night but keep a wood option open for quick fires to take the chill off. WB
My plan is to direct vent the gas furnace out of the basement and use the existing chimney for the coal stove which I am going to put into the dining room below the bedrooms that I most need heated.
The Chimney is over 100 years old as far as I know. Do I need to line the chimney? I have looked for good posts on chimney liners but haven't found the info I need. Any advice on lining a chimney is welcome. The Chimney is brick ad mortar and runs right up the center of the house and is totally encased in the walls.
