Terra Cotta as vent pipe?

PostBy: kstills On: Mon Nov 11, 2013 2:54 pm

Yes, no?

I have about a 12 foot run, which would be ~15-20lbs. I have plenty of ways to support it, just wondering what code I would be in violation of if I did it that way. :P

Ummm,,......see if you can trade it for some real smoke pipe. I think the likelihood of cracking would discount the few dollars saved.

Stick with good metal black pipe. Its whats meant for the application and will be alot less of a headache in the long run.

The black pipe rots, which is what I'm trying to get away from (corrodes, if we're being technical). Rubber flue 'tubing' for high temp applications would cost as much as my boiler, and I can't find anything resembling a corrosion resistant coating to paint the metal pipe.

That boiler isn't moving anywhere, so hanging terra cotta wouldn't be an issue, if it can take the heat that is.

The bigger question is...why is your vent pipe rotting? Either the boiler sits idle over the summer with fly ash in the pipe, or you have flue gasses condensing in the pipe.

My dad has been using the same galvanized pipe for 4 years. I have three years on black pipe and it still looks great.

Galvanized is standard installation for a boiler. If you are using the boiler year round the corrosion won't be a big issue, you'll get at least 10 years out them and that's a very conservative estimate. You can figure about 5 years otherwise, be sure to disassemble at the end of the season. Wash them out with baking soda and water and store in dry place.

I'm using galvanized pipe,after 3 years the pipe is fine,except for the last 8" piece that go's into the thimble(yes,it was planned that way for the 8" piece to be sacrificed) It's easier/cheaper to replace the extention into the thimble than the whole pipe

How do you join terracotta and how do you support it and how do you gain access for cleaning?

If you want long term durability... I use a 7" diameter, eight foot long stainless steel smoke pipe on my Van Wert stoker, and smoke pipe is twenty years old. Now it has four or five small pin dots in it...but still in great shape..I figure I can get another five years out of it, easily.... I pull it apart and clean out once a year.
