Just noticed that the stainless insulated chimney for my wood
stove is running pretty hot to the touch. There is about 12 feet of it,
and it all seems about the same temperature. It's definately cooler than the uninsulated pipe right off the stove but still...
Anyway, my question is how long does this stuff last and is
it normal to get hot like this when old? I'm guessing maybe the
inner liner is perforated...?
