But when I did it a few years ago a couple of folks appreciated it.

20 degrees out this morning with 20 mile an hour winds after down to 11 at sunup. Needed to look at the liner so I stuffed the IR thermo in my coat pocket and went up to check the uninsulated liner in the double flue mass of bricks chimney.

Stove was at 504 going up and coming down. Top of the 21 foot liner was 328 degrees. Last time I did that years ago the stove was at 400 and the liner up top was 235. Anything over the boiling point of water, around 228, is fine with me.

Like I said, useless info. I know, insulate the liner and it would be 10,000 degees at the top. >>

Seen a few of yours where I thought the same thing. ;lol
 
Good man my friend. Keep doing what you do. Only pro sweep on the site these days.

But I still ain't gonna bust out those tiles.

For the life of me I have never been able to figure out what a thermometer 18" up from the stove could tell me about what is happening 21' up. Or any feet up for that matter.

I consider the things about as informative as, well can't think of anything.

Hey, I think at that temp one of those heat-robbers would actually work! ;)

It may not tell you what's going on above it but it tells you what's going on below it. I can use one to tell me when to close the bypass on a cat stove (run flue temp at X degrees for X min, close bypass and get guaranteed light-off about every time. The same would work on a tube stove, I'd imagine...
 
If you are measuring your flue temperature near the exit and it is above 220ºF it is telling you that your chimney is probably safe. With a few more parameters for a correlation it might actually help someone else.
 
OH MY GOODNESS. Uninsulated liner in a brick chimney with the tile in place. The horror. And to think I thought you knew a thing or two about wood burning. ;)

You bet. I figured saying he was the only pro sweep would have gotten a rise out of webbie3650. ==c

This thread has inspired me to go out today and get the ladder and IR gun and get up on the roof.

I just need to shovel 18 inches of snow and ice off first.;lol

On second thought, maybe just another cup of coffee and a few minutes in front of the stove will suffice.




( I wonder how accurate the IR gun would be from 22 feet below) ???;)

228? Is that new math, last I checked BP was still 212*. Been a couple years since I have checked though...>>

You just checkin to see if anybody in the class is actually paying attention?! ;lol

Pure water, 212 at sea level.

I don't have a beach in front of the house. And ain't so sure the water in the wood is pure.

Where on earth did you find that picture of me? It's a good shot, that's for sure!

I do much more than sweep flues. I get to be part of the entire install of chimneys, stoves, fireplaces, liners. The whole 9 yards. It's a different scenario everyday.

I love what I do and enjoy sharing it with others.

Unless you live in New Orleans your boiling point would be lower, not higher. Good point on the "water purity" though

My chart shows
1k ft elevation = 210.1*
2k = 208.1
3k = 206.2
 
Went through this whole drill six or seven years ago when I posted on this subject. Boiled three samples of our tap/well water with three different heat sources and using three different thermometers. All started boiling between 225 and 230.

So I use 228.
