Wes, do you see any issue using a thermocouple probe on single-wall pipe? That is other than making sure it is of the proper temperature range and insulation rating?
Probe for single wall??? Yay or na

Ok so I will get one of those is that where the dig stove top monitor is.
I have just at 5.5 ft of single wall what advantages would I get with double wall. I hear u guys talking about that.

Higher flue temps to help keep the creosote away and maybe a better draft because of that. Which could help some with not so great a draft.
I don't see any reason why it would make a difference, single or double wall.
I have had a probe on the basement Fisher ( single wall) for years.

I'm going to get the Auber and mount the probe it in my single wall and see what for readings I get.
Then when I switch to double wall I will mount the probe in that at the same height and report back .

I'm going to order the auber. I'm also going to do some research on double wall pipe now and see if it will being it me any. That's another reason why this site is awsome good group of smart guys to help out us newbies. Thx for all the replies
So Wes, are you saying both of your thermometers (electronic and mechanical) are reading the same temperatures on that single walled pipe? Or is the radiant heat from that single wall throwing off the readings on that mechanical probe?
Actually , no the mechanical thermo is a magnetic mount meant for single wall pipe,
it reads fairly close to the IR gun, and is about half the temp of the internal thermocouple probe.
Hope this makes sense.
OK, my mistake, I thought the mechanical thermo was also a probe type. I was curious how significant the difference would be.
I've been eyeing some of those Auber products just not sure if I want the looks of the wire hanging around my stove.
if anyone installs one of these Auber probes please keep us posted.

I just bought this but exchanged the 4" probe for a higher temp 10" probe to monitor my cat.
Heard back from Auber. They recommended using their 2" probe for 6" round single-wall stove pipe if you want a probe reading of the flue gases instead of a surface reading of the pipe.

They work very well on single wall if mounted correctly and a quality part. I bought an industrial probe made for a high temperature environment. It moves very quickly and the probe is entirely inside the pipe and only mechanical parts outside it. The flue internal temps move instantly and the magnetic one takes a half hour to catch up. At the end of the day an external skin temp on a poorly fitting surface thermometer. Using a flat plate on a round pipe does not sound very sensible when 95% of the surface mount is not even touching the pipe compared to 100% of an internal probe.
Did they mention why the 2" probe? You'd think 3" would put the probe tip dead center of the pipe?
Do these probes take the readings from the probe tip or from the whole probe?
No. I think they sell a 2" and 4". 4" is recommended for more accurate readings in double-wall pipe. Not sure about single-wall, or if we are talking something like a degree or two more accuracy in this circumstance or a greater delta.
I think I'd go with a 4" probe and pull it out an inch so the tip sits dead center of the pipe.
Dead center is probably not the most accurate area due to the probable vortex created in the stack. Just a hunch, but that is most likely why they make a 2" probe.
why would this be any different then the 4 inch probe on a 6 inch pipe?
Lets say you insert the probe from the front to the back. If you put in the 2 inch,,the end of the probe would be 2 inches from the "front"of the pipe. If you put in the 4 inch, it would be 2 inches from the "back" of the pipe. Whichever you use, the end of the probe is 2 inches from the outside of the pipe. I am assuming they read from the end of the probe.
The Aubrens unit has a small plate on the end near the wire for screwing it onto the chimney, so I would want to have it placed all the way in so that it is fastened properly. I have the longer probe, but mine is into double wall chimney. The read-out is instant. IMHO having it in the center or a bit offset is neither here nor there. The important thing is to get instant readings of what is happening in your chimney. If the reading is a bit off due to placement, that's still 1000% better than waiting a half hour for the stove top thermometer to tell you what's going on.
In case anyone wanted to be more convinced - do not try this at home, professional driver on closed course warning
- from a few nights ago.The stove top was 580. The flue reading was 600. The stove was still half full but I wanted to top it up before heading to bed. At the start of one TV commercial, I opened the stove to see what was happening with all the super cold weather and wind. Going great, but I walked over & grabbed a few more splits from the wood pile 12' away. Heard the alarm go off at 900. By the time I got back to the stove, threw in the few splits, closed the lid and closed down the stove, the flue temp had hit 1800! I got back to my chair and the commercial was just ending. All this in under 60 sec. The stove top thermometer didn't budge.
Yes, I know you never add wood to a good fire but we've all done it. Normally this dramatic a temp would not happen but the wind was wicked outside and the stove was closed fully and still was burning a bit too hot. Only having a digital flue thermometer would allow anyone to have an idea how dramatic things can change so quickly. Personally, I think they should be mandatory on all stoves.
