Does a direct vent system have to exit the stove and go directly through the wall to the outside or can some piping be used?
I'm considering installing a second coal burner in the cellar to warm the place up (It can get down to the upper 50's in the winter) with a hot water coil to help keep the oil-fired hot water heater from running.
I don't have access to the flue for the furnaces, there are two oil burning appliances running into it now and I don't want to run a 3rd, esp. with a different type of combustion.
Building another chimney is not an option, I have very little room between the top of the foundation and the bottom plate as well, I'd have to box in part of the window opening.
Any advise?
