My chimney is a good bit above the ridge line of my roof and I live at the top of a hill without much around to break up the wind. All of this combines to cause an extremely strong draft. Last year I installed a barometric damper after not having luck with a manual pipe damper, and this and it made a big difference. However, the baro often stays wide open, especially when cold or windy, and I continue to lose a lot of heat up the flu. It's to the point where I hear it whistling up the pipe, causing me to have to burn much hotter than should be necessary to keep my house warm.
At this point I am considering two options: I've heard that installing a chimney cap can help with this problem, and I figure it wouldn't hurt to have a cap anyway, so I may try that. I've also considered installing a manual pipe damper in addition to the baro. Does anyone know either of these possible solutions would be adequate in reducing my heat loss? If I do put in an MPD, should it be between the baro and the chimney or between the baro and the stove? Any advice or other ideas would be appreciated!
The key point is .. the baro stays open 24/7, I'm no expert on chimney draft but I think this thread got side tracked. How will a bigger baro end this problem ? will the 8" pipe reduce the vacuum at the baro ? I'm asking because I do not know the answers to those 2 questions. Haven't seen any figures on what the actual draft figures are which would be the first step to correct this problem. If I understand the original problem correctly,it is not that the stove is overfireing from too much draft but that the baro is held open by too much draft, can baro be set "heavier"to overcome the draft? again I hope to learn more on the baro issue thru this,Thanks
