How well will this chimney work?

PostBy: NorthernIndiana On: Mon Jan 13, 2014 5:43 pm

I want your opinion on how well this chimney will work. I cannot build it in the center of the house. :x How well do you think this will work. I'm burning coal (likely a stoker). Masonry chimney with a clay liner. Located in northern Indiana. Will I have problems with draft due to a cold chimney?

From your drawing it looks like its not tall enough, but IDK, its something like three feet taller than anything within ten feet? Someone?

Also I would use round tile, it fits together like Lego and will draft better.

iv'e built a lot of chimneys in 54 years and that one will work...the only problem i see is cleaning it. 7' is out of reach for getting a chim brush to work without a scaffold, bucket truck, or a crane with a monkey cage...

It will work fine--but the proof is in the pudding ya know. ;) 8 foot ladder from the back side--hang on to the chimney & brush away--that's why the Creator gave us kids/young men :)

I think it'll work great. You show a 5/12 pitch.... I made up a drawing that's to scale. A chimney should have 10 feet (or more) as pictured. It looks to me that you'd be OK with 5 feet instead of 7.... but why push things? I like your idea of 7 feet.

Yipes! Is that Russian cleaning the chimney or emptying his ashes? LOL

It won't work its only 1 dimensional. Chimneys need to be hollow and 3 dimensional.
Just kidding, I get a little goofy at the end of the day.

Seriously I don't see a problem it should work fine. You can always clean it from the bottom if designed right. Also with anthracite it won't need to be done very often. I also agree with the round flue's.

I'd shoot for a min. of 4' above the peak of the roof. Problems occur when exterior chimneys are not built high enough, not simply because they're exterior chimneys. Make sure to use a type S mortar on the block, heatstop II (not pre-mixed) on the tiles and fill the void between block and liner w/ vermiculite.

The 10-2-3 rule is a min. requirement for code and fire safety, NOT a recommendation on how to make a chimney function properly.

because you've got an exterior stack, add the extra 2'. It won't cost much now, but you'll be thankful for it later.

You might consider some substantial permanent bracing at a couple points especially if you go 10'. I sure would not lean a ladder against the chimney and try to brush it. No Way. You would look pretty foolish when the EMT's come to put you back together........if you survived the fall...with blocks on your chest. It will be more than 'take two aspirin, and call me in the morning'. Think safe, act safe, be safe...much cheaper in the long run, AND substantially less paperwork post event. :idea: :idea: :shock: :idea:

Why run it inside the house? Why not just move it out to the exterior and box it in to match the siding?

I thought about that, but from what I understand I should keep the chimney inside the envelope of the house as much as possible. As a colder chimney is more likely to experience draft problems. If I push the chimney outside and build a box around it, will it stay warm enough to eliminate draft problems? It would sure look a lot nicer if it were encased, although I'm in Amish country and a big ugly run of block chimney isn't an uncommon sight.

And thanks everyone for the feedback!

Put it outside on the gable end. While your at it put in two flues.
It'll make it stronger and you can never have enough flues. Let
the flat hatter build it for you.

keep it inside the house as much as possible, but, if you go tall enough, it's not as significant of an issue. Insulated chases can be problematic. If you want it to look nicer, go brick above the roofline or use quickrete quickwall for a "stucco" look on the stack that is thin and holds up well.

tsb has given good advice, I've known many who wished for more flues, but none that have wished for less.
