Ok Graig I just read about all of the work you did I would not cover it either I think you got it pretty well sealed you should not have a problem aslong as it is sealed up good It could also help to keep it warm once the stone heats up it may hold the heat in The sf 250 is a real heat machine it put out the B.T.U.'s I think it will hold 100 lbs of nut they rated for 3000sq.ft should not have any problems keeping the place warm keep intouchpa coal cracker wrote:It took me 2 years to clean the cellar walls off and repoint them. The old mountain stone, laid up with topsoil and lime, and then parched on the inside. I repointed with type s concrete, and added another zone with a cast iron radiator, made a big difference. (I can't wait to get a coal burner down there), It used to be a real damp cellar before I did the work. Turned out really nice. I'm not going to cover it up. Oh and that's what I had in mind with the temp tank and the cast iron radiator. I'm going to get started as soon as the weather breaks this spring I have to put up a chimney. Would the standard 8"x8" flu be ok or should I go with the bigger one, I think they are 8x13 or something like that? I'm planning on getting a Harmon sf 250.
While I don't know your specific home heating if you are going to build an new masonry chimney consider making a dual flue chimney. I know it's more expensive and more work but it gives you the option of have a second fuel appliance. For example you could run an oil fired boiler into one flue and your coal stove/furnace/boiler in the second. This permits designing a system with automatic switch over should the coal fire go out. Fire code requires a independent chimney for each solid fuel appliance. I'm not saying this is the only way it will work but that's what todays fire code requires. Usually a dual 8"x8" flue is ideal. Check with Harmon for there specific flue requirements.pa coal cracker wrote:I'm going to get started as soon as the weather breaks this spring I have to put up a chimney.
