We live in a high wind area in the Rockies. Commonly get winds in excess of 80mph in the winter up here @9600ft. Having a overdraw problem with our woodstove with winds above 40mph. Draw is not a problem even in zero winds.
Have a Scan Anderson 10, about 27 feet of ICC double wall pipe, and a ICC wind/rain cap. Burning oak, the fire will last about 5-6hrs, on windy days maybe an hour. If the door on the stove is open 6-8 inches the the draw will slam it shut. The dealer I bought the stuff from has never seen my problem. He's no help.
I've added a inline danper about 4ft above the stove, little improvement, even with damper closed, still allows some air to go thru, not technically closed.
I contacted a dealer in Laramie, Wyoming thinking they have to deal with similiar problems with high winds. He suggested a Monsoon cap from a guy from Washington state. Tried two different versions, no change.
Our prevailing wind is from the west. I know this wasn't the best solution, I attached a piece of sheet metal on the west side of the cap blocking off the wind from the west. That helped except for when the wind came from the east.
One of my neighbors has a Vacstack cap, and he put a barametric damper on a tee a few feet above his stove, the open end of the tee is open to the room drawing air from the room up the chimney. I see a couple flaws, aggresively drawing warm air from the room, and the potential of feeding a chimney fire with lots of air.
I'm considering adding one or maybe two more inline dampers and possibly a rotating cap?
Any ideas?
Thanks, Kevin
