When I was burning the woodstove where I now have the Harman I installed a bathroom ventilating fan in the wall between the Kitchen and the Dining Room, where the stove is. The heat from the pipes and the top of the stove was drawn through the fan which I connected to a 4" aluminum duct that I ran through the laundry alcove and down the far wall out into the kitchen. The arrangement works fairly well. Now with the coal stove and the baro damper, the pipes don't get as hot, and the blower on the stove keeps the top of the stove cooler, so it doesn't radiate as much heat to the fan.
I realized I had to do something, so when I was at the H.D. today I picked up a few dryer ducts for narrow spaces and quickly made a little device that sits on top of the pipe just before the thimble and has an outlet just in front of the fan intake. It looks so hidious that I refuse to post a picture of it here. My wife hates it, but I tried to sell it by saying that it's "only temporary" until I can determine how well it works, and that it's not attached to anything, it's completely removable if we don't need it.
It actually works fairly well, I need to build a better more acceptable duct.
I think my family is secretly planning a little "vacation" for me at a nearby clinic.
