Thank you for the responses and information.
My home is one story L-shaped ranch. Kiitchen, eating, (and contiguous den with 6 foot opening from eating area all contiguous space and open to one another. kitchen and eating area is about 15' by 26'- plus 12' x 15' den area. Doorway from den to a bedroom (one thermostat for one furnace by this door at least twenty' from potential stove location with large closet between) and on opposite end doorway from kitchen to large vaulted ceiling living room roughly 20' x 27'
Left to right: den (brick fireplace wall on end of house), eating area with backdoor to outside, then kitchen. all contiguous. All this is about 15' x 40' of open area before any inside doors. Door to living room has pocket door that can be closed or open. but usually in winter I close it. House is L-shaped and uses two gas furnace systems. I close off one area that is not used that much and live almost 100% in the kitchen to den area. Yes, attic space above all this area. except vaulted living room beyond kitchen.
I would like to place the coal stove along wall directly opposite back door. This would be near the apex or wall directly beneath the highest roof point. One other consideration is radiant heat wires in plaster ceiling. I would need to take pipe through ceiling carefully and protect the radiant system. I love the radiant heat from it, but it is way too costly to use being electric. My meter goes very, very fast even with only one of the rooms radiated. I have all these heating systems, but all are too expensive to use.
I am not concerned about hiding the pipe. Actually, I expect to see some exposed, then would like to use cement backer board to build out around the upper part and have a nice mantle and ceramic tile below and behind stove under mantle if possible. All this only if I can meet clearance requirements, etc. Mostly I am concerned about the piping and requirement of fresh air and venting of gases, etc. Is is possible to use inside wall and still accomplish what I would like? How hot really does a coal stove get? I think I have seen 600 degrees mentioned. I don't wish to fry here. Just be warm.
Only available outside wall is window wall beside back door and is going to have additional sink and kitchen cabinets eventually.
So this would mean I have to keep fan motor running anytiime stove is being used? Would this defeat my attempt to save on electricity (as well as gas) since my gas furnaces also use electric fans that increase my winter bills? If I cracked a window open slightly, would I still need the fan arrangement for venting? Or is that a dumb idea?
One relative discouraged my coal stove idea, told me to buy various other things using either gas, electric, wood. I am low on trees here and like to split wood, but what I am using came from trees I had removed and I use den fireplace (rather large opening) strictly for esthetics now and then, not for real heating, since it is not the best for efficiency. Am I on the wrong track with a small coal stove?
Thanks again for any help. Hope this info clarifies somewhat. What a great forum. I am enjoying reading through it.
There are few dealers nearby (Huntington, West Virginia) so that also is a problem if dealer must be near for service. (I do not recall Dad ever requiring service, but that was then. He had this large brown metal coal-burning stove beside backdoor withe the pipes going directly outside and up. I do not recall any blower if it had one, but the space was large about 30' x 30' and Dad may not have been as careful as he should have been)
