The Chimney is the Engine that runs the Stove
Stove performance is determined by chimney condition, height and diameter or in the case of a masonry chimney dimension of the clay liner. All of these factors affect draft. Atmospheric conditions also play a role. IE what is the weather like? High pressure, cold and sunny or rainy with a low pressure inversion. Is the chimney straight up and mostly inside the envelope of the dwelling where it stays warm, or on the outside where it is fighting the cold? Hot air rises! If the chimney is cold it is more difficult to establish draft causing the unpleasant and potentially dangerous smoke spillage back into the home. Today with our high efficiency stoves, less heat is going up the chimney, so they tend to be more draft...
