Wind chimney caps anybody?

Still haven't ordered the chimney for the new stove. Do any of you have experience with a special wind chimney cap, if sp what kind. Will they just fit or do they need adapters

 

I am not familiar with a wind chimney cap. Could you share a photo?

 

Is there a reason you think you need one?

 

Yes, we are on the side of a hill and get very strong downwinds. The winds here are very exaggerated.
Here is an image of one i found.

 

I have heard of a couple people using them but know nothing about them

 

What is a down wind?

 

Being on the side of a hill we call a "Down wind" the north wind that blows down the hill towards our cabin and the house, often with considerable force. The hill is much higher than our chimney will be and i can't see a good draft happening on those days. When i burned wood piles outside and got that kind breeze ( I won't burn in high winds) it was much harder to get it going than with the "Up winds" that come from the south.

 

Sounds like you might need one of those,
You probably don't want to buy two different caps but you could try it with no cap to see how your draft is first, for comparison

 

Yes, easy enough to add the cap if you think you need it later and not spend the money now. I would wonder about the wind cap reducing the draft of the chimney but I know nothing about them.

 

Myself, I would wait and see how it drafts before getting overly concerned. While winds can hinder draft, they can also help it along. I do understand what you mean though, my stove is harder to get going on a cold start with an east wind.

 

When I lived in Alaska, folks that lived on the buff along Cook Inlet
had to have directional caps because of the wind.

 

i thought about wind caps but talking with companies, I gathered it also increases draft. i added 3 feet of stack and a selkirk class a cap and did the trick for me. It depends on the situation.

 

I have a problem with strong winds back drafting into our cabin( home) . A friend who comes from the Oregon coast told me about a swivel chimney cap that looks like the ones Justdraftn posted pics of.
Our strong winds come from both north and south so I need one that can swing around like a weather vane.
Good thread.

 

Just found this sight Wind Directional Chimney Caps - Steel Rotating Wind Blocking Caps

Looks like this is just the ticket.

 

Sorry life happened. Hot water hose on washer broke while nobody was home. What a mess

Thank you everybody for all the help. Cold trigger finger, I strongly suspect we'll have to get a cap like that.
However, I don't want to end up with really bad updrafts and go through tons of wood.
I have ordered the regular cap for now. We'll see how it works and go from there.

 

If your stove is an air tight stove. It will only draw as much as you let it by opening the draft. When a wind event is happening , either the stove will draw real well Or it will nearly or actually back draft. Wind is wind. . Its a variable medium. Anyway the information is there if you do need it. I will be ordering one as I can afford to close my stove all the way down @ 30 below . Just because the wind came up.

 

Burrr, that is cold. I'll let you know how it goes this winter. It will all depend on the weather.

 

A manometer/draft gauge can be real helpful in seeing what is happening in the stack. I'm using a UEI 151 Manometer right now on my stack to see how this new stove is behaving in a nasty NW wind storm we are having right now.

You will see if the stack is gaining negative pressure with the wind blasts or losing negative pressure.

 

I didn't check my spelling . Should read , Can't afford to have to close my stove all the way at 30 below.
I guess I'm a timber beast , not a typist.

 

Thanks jdonna, never heard of that. Will check it out.
