Is the oil burner a boiler (water) or furnace (ducts)? If a furnace it could be practical.
Yes, it's boiler with water, I have base board heat. I do have a seperate A/C system that has ducts to the first floor, main living area, which I was thinking would be good to use from coal stove but not sure how I would be able to place stive close enough. Above main floor are 2 bed rooms, office and bathroom, heat goes up there as its open.
Is the chimney on outside wall or through the house?
Chimey is inside, just about in the middle of the house. I will take a pic tonight of the furnace and chimney area. The unused spot in chimney right above the current pipe for furnace seems perfect to use, just need to remove cap and put a pipe in it. Just remove whenever selling the house.
