Hello all,

I am brand new to this site, and am very excited to hear your advise. My wife and I bought a 50 acre patch of pristine old growth white pine forest in central Ontario last spring. We have built a tiny (320 sq.ft.) off-grid house next to a spring fed lake, and chose to heat it with a RMH. Although unfinished, we have had a few fires through it and are quite pleased with the results.

My issue is with the wind. I have the exhaust on the lee side of the house where it is most sheltered by the structure, I bodged together an impromptu wind baffle with a minnow trap capping the 2 ft vertical section of 8 inch duct, then place an upside down bucket over the whole works. All of that is under a very minimal hutch I built to support the snow load, right now we have 4+ feet. This works for all but the windiest of days, but now that I am out of the bush and can buy more materials, I'd like to return home with a better solution.

Does anyone have any experience with the "H" shaped baffle made from 3 T-joints that is depicted in Ianto's book?

How about a "vertical draft diverter", like to kind used to keep gas pilot lights from extinguishing?

Sorry I don't have any pics of my current baffle, but I do have some vids of the build.

Thank you for any suggestions!

Carl, I am just a newbie but I would buy a commercial made wood stove cap and pipe and get it up above the roof a bit. Jay

The H used to be THE high wind backdraft solution for all stoves.

I hadn't seen the vertical draft diverter before, that may work just as well. Looks like the same concept, but I bet cheaper to make.
