Survey About the Type of Flue Pipe You Use

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Which type of flue pipe, from the boiler to the chimney base, do you use?

Galvanized, Black, or 316 Stainless.

Right now I have galvanized because it was free. After one year it's showing signs of rust on the inside of the pipe. Next year I plan on replacing it with black.

I'm asking because galvanized is standard around PA, but in other states, the inspectors are questioning the use of it.

For me, if I was installing a unit expected to live 50 years or more, I would use 316 stainless right off the bat.

I just priced SS pipe 8" x 36" about $90.00 :cry: . Galvanized pipe 8" x 60" about $16.00. ;)
Galvanized will last around 3 to 5 years depending on dampness.Good question though. :idea:

I have used all three types. Galvanized is ok on an oil burner or maybe some stokers that have maximum flue temps below 600 degrees. I'm not sure what temp galvanizing starts to smoke off but I think it is over 600. Take that with a grain of salt. I put galvanized on my Warm Morning batch stove (hand fired) and in highensite I consider that a mistake. When I started the stove and had flames licking up the stove pipe it gave off poisonous fumes. I opened all the windows the first time I fired it off when the worst of the fumes where given off. I'll never do that again. I will never put galvanized pipe on a wood stove or hand fired coal stove. The stainless pipe I used on another instillation discolored some but it is fine. I had bought it used from someone who sold me some pea coal...cheap. I'd never pay full price for it. Not that it isn't good; I'm just cheap. I think the black painted pipe is the best choice for cheap focks like me. When it rusts to the point I can easily push a hole in it time for new. I usually get about 3 years out of it.

Galvanized should not be used on solid fuel appliances. If you have it, I would not rush to replace it. However, I would recommend replacing it with black stovepipe or better if you so desire when replacement time comes.

Stainless 316 is available through Olympia in Scranton. It's good quality, perfectly round and has welded seams. I paid about $600 for 25 feet, plus a tee, plus custom cap, and some odds and ends. They may not sell direct to you, but you can buy it through efm.

This 316 stainless pipe from Olympia supply..... Can it be used for external flue pipe, or a liner only?

I used galvanized pipe on this building last year temporarily to get the furnace up and running, and I am wanting to get to a stainless pipe.

Any other suppliers out there that you know of? I preferably need 9 inch.... the only thing I can seem to find on the net are those Dura-Flue that are double walled.... and I just want single wall.

Thanks

Used black first time using coal, this was the result after ONE SEASON: ( in moist basement )
I now have 304 stainless, but this is what it looks like going on yr.3 :
Stovepipe, stainless yr.3 (2).JPG
Holes formed after first season. Getting pretty big now at beginning of 3rd season. BUY 316!!!!
Stovepipe, stainless, yr 3.JPG
90* Elbow, surface rust
BUY 316!! Don't try to save a buck like I did.

FIRST MISTAKE: Black stovepipe -- duration: 1 SEASON
SECOND MISTAKE: 304 stainless stovepipe -- duration: 3 seasons (less, if you don't like holes)

BUY 316!! I'm kicking myself now for not ponying up the cash when I had it! :sick:

Yamabond will become part of my stovepipe this season.... :lol:

Nothing wrong with galvanized. We have the same galvanized pipe for years, might even be original but I'd have to check. Replaced once at most in more than 25 years. Keep in mind the furnace runs 24/7. Keeping the moisture out of it is the key. I know if you keep it shut down in the summer you might get 5 years from a set of galvanized pipes but I wouldn't expect anymore.

9 " :? efm 520 is 8" flue and the 1300 is a 12" flue what are you using besides the two efm's that you need 9"
