I posted about this a while back, but did not get a response, so I'll
try again. My house has a fireplace that is large and somewhat drafty.
The FP was originally used for cooking when the house was built (about
1820). I am thinking of putting a wood stove in the fireplace, and
blocking off the chimney immediately above the fireplace except for the
hole for the stove pipe. The fireplace opening in the room is 6' X 7'. I
think this will make the room much warmer and less drafty in the winter.
I have two questions about this:
1) What would you use to block off the chimney with? Is there some sort
of fire/heat resistant board I can use?
2) Is it necessary to run the woodstove's stove pipe all the way to the
top of the chimney (two story house with attic), or is it acceptable for
the stove pipe to simply exhaust into the chimney? Note: the chimney is
not a modern flue chimney, but is a large old chimney (probably 3 feet
by 2 feet inside). Also, the chimney is topped off on the roof with a
flagstone which prevents rain from falling into the chimney.
Below is a pic of the fireplace:
