please help newbee with chimney design

[steveh2112]

hi all, I've just bought a house in upstate NY and would like to put a wood burning stove in. I'm not clear about the chimney system. It's a single story ranch house with a metal roof.

First question is should i go though the wall or the ceiling? I'm planning to put the stove in the living room which has an outside wall and I'm happy to space the stove 18 to 24" from the wall so i was thinking single wall pipe on the inside.

Looking at the cost of the Duravent stuff, it seems the pipe will end up costing more than the stove (which i'll buy second hand), so I'm guessing through the ceiling/roof will be cheaper since doesn't need the Tee and all the other stuff and the double wall section will be sorter. Is that correct?

I know I should use an air intake pipe to feed the stove with outside air to avoid sucking cold air into the house. does that air intake pipe need to be anything special? will single wall be ok. should it be 4 or 6"

Also, i'm thinking a lot of heat will go straight out the chimney with a though the roof chimney. Is it ok to put a ceiling fan above the stove to help circulate the hot air more efficiently?

thanks

Straight up is better for many reasons.
Look for Selkirk supervent. It’s sold at many box stores, much cheaper and still a solid product.
Your outside air supply will be either 3 or 4”. Single wall flex is fine for that.
Using a box fan on low aiming toward the stove from a distance is most effective.

Great info, thanks

so i was looking at the selkirk ceiling kits at lowes and there are 2

and

https://www.lowes.com/pd/SuperVent-8-Piece-Chimney-Pipe-Accessory-Kit-for-Ceiling-Support/3572826

the second one has the big box, the first one doesn't.

which kit do i need and what should i get for the inside pipe?

thanks

The first one is for a flat ceiling, second is for a cathedral. It will work on both ceiling types though, unlike the first one.

 

[steveh2112]

ok, thx. so one more question, should i put a damper in the chimney pipe and if so, how high above the stove top?

 

[webby3650]

Maybe, if it’s an old smoke dragon. Hopefully you will be picking up a modern stove. Not needed or recommended for modern stoves.

 

[steveh2112]

doesn't a chimney damper help control the heat output while trapping most of the heat in the stove?

Depending on the length of your chimney a damper may be needed. If it is 25 foot or less you probably do not need one.

 

[steveh2112]

ok thanks, its a single story house so i expect a total length chimney of about 10-12' so i guess not needed then

Menards has good prices on Supervent products. I’d price match that with Lowe’s.

 

[steveh2112]

don't have Menards in NY.

With a chimney that short your more likely to have the opposite problem, not enough draft. If you haven't purchased the stove yet make sure you get an "easy breathing" stove.

 

[steveh2112]

since i'm buying second hand i doubt it will come with a full spec sheet. how would i know if its "easy breathing" or not. is there something specific i should look for?

 

[kborndale]

Drolets, regencys and Pacific energy's are generally considered easy breathing brands, I'm sure there are a few other brands as well
