Is the existing chimney built for the furnace? What kind of furnace is it?
A wood stove requires a 6 to 8 to 10 inch metal flue depending on what type
of stove it is. Most of these stoves require Meta-Bestas, or triple wall
flue. The above stove pipes need clearance from combustibles.
Many people insert a stove pipe in an existing chimney to handle the "new
wood stove" but in your case the chimney is being used by the furnace. So,
I would not recommend your sharing the chimney
with the new wood stove and with the existing furnace.
If the chimney were large enough, and lined with fire brick, and clay
chimney liner, and in good shape, it may be possible but without knowing
that I would not install a wood stove to it.
No, against code.
A wood stove basically needs its own chimney. Furthermore, a wood stove
needs a specific "size around" chimney depending on the *model* of the wood
To install a wood stove "to code", you basically need to follow the
manufacturer of that wood stove's installation directions for that SPECIFIC
model. This means specific distances from the wall, a certain r-value floor,
hearth distance out from the front and sides of the wood stove, and a
certain size chimney.
Also for the wood stove to work properly, you need a good "draft". This is
caused by the sides of the chimney getting hot enough to cause an air flow
upwards. This in turn will draw air into the wood stove. If you don't get a
good draft, then air will not be drawn into the stove and the fire will die
out. Then the chimney needs to be cleaned out once or twice a year or you
may have a creosote fire which can burn through the chimney into the attic
and burn down your house.
Also special stainless steel double wall chimneys are required and must be
installed in a certain manner so the heat from the chimney will not be too
close to any wood framing in your ceiling, attic, or roof. Again keeps your
house from being burned down.
Then the "clincher" is that for your wood stove to be covered by your
homeowners insurance, it must be installed to code, inspected by your local
building inspector, and then inspected by the insurance company. Then they
will add it to your policy and you will be covered.
If you don't install it to code and have a fire which burns down your house,
then the insurance company does not have to pay a dime!
When I installed my wood stove, I thought about the insurance thing and this
made me decide to do it by the book. This cost about $2,000.00 for the
chimney and $1,000.00 for the wood stove. Of course installing to code
pretty much makes it a safe wood stove and chimney with a low risk of fire.
I guess that is the general idea...
Note: I got the largest stove I could find and am glad I did. I need paper,
kindling, and about 3 pieces of wood to start a fire. Then there is about 3
or 4 inches of ash in the bottom, then I need space above the 3 pieces of
wood to add more wood to the fire. Wood can come in all shapes and sizes, so
much easier to have fires in a larger stove. And the larger the piece of
wood, the longer it will burn. My large stove turned out to be just the
right size with just enough space inside for the above. I think I would be
frustrated with anything smaller. (Would not be enough room inside.)
Stove I purchased...
No, and since you are asking questions like this you really need to get
up to speed on all of the other stuff that applies such as clearances
from combustible surfaces etc.
Just don't drag the thing in and hook it up. For many people that was
the last home project they ever did.
