With a stove, typically around three quarters of the heat generated goes into the room, with an open fire its more likely to be the other way around with three quarters of the heat going up the chimney. This means that the smoke from a stove is great deal cooler than from a fireplace. The result of this is that a stove takes a long time to bring a masonry chimney up to operating temerature. This can mean that the stove will not draw properly, at least before it has been going for a good while, and the cooling smoke will condense, causing excess soot and, more dangerously, tar deposits. Tar deposits are not removed by a sweeps brush and cause chimney fires and you may get black tarry condensate leaking out through the bottom and sometimes even through the mortar joints of the chimney.
For this reason it is good practise to line and insulate a chimney whenever you fit a stove - see Lining a Chimney
