Surface or internal flue thermometer

[stop drop & roll]

I need to replace my stove pipe thermometer. I have a VC intrepid II that I use a griddle thermometer and a stove pipe thermometer to monitor combustion temps. Should I buy a probe type or another surface mount. What's everybodies opinion? Thanks.

Definitely a probe unit - they don't fall off when they get hot (edit - magnet mounts should be screwed or wired on, but I'm not sure how often they get the right treatment), and they respond quicker to temp changes.

I prefer not to put a hole in the pipe. Have also never dropped a magnetic thermometer off the pipe, as one strand of safety wire goes a long way.

I ran my surface mount up to 900 degrees at one point today but I think it was too scared to jump.

I got mine that hot, and all the black paint turned white - I now have a nice polished aluminum one with no numbers on it anymore :-S

hahaha that is a good one, make sure you monitor that one closely :lol:

I would pitch both of those overheated thermometers and replace them. What caused the high temps?

Too much time on the forum, not enough time closing the air down = stove top glows red, paint turned white. I use it as a trend indicator more than actual temp measurement - that said, it gave the same indications under the same conditions before and after the overfire.

What I really want is a probe thermometer that will work on my insert and gives me a buzzer when temps get above a set level like 800*F. Still working on it, but I have a plan....

Sorry for hijacking the thread.

There's a guy on here who's starting to make alarms. He even offers options such as high/low, stove top and or flu, etc..
I got one ordered and think they should be mandatory for ALL woodstoves.
If you're interested, I'll look him up for you.

I never had a problem with the surface mount, it was my three year old twisting the needle around(when it was off the stove while I was cleaning the pipe). I'm just looking for some input between the two types since I have to get a new one. Ken, that alarm system sounds interesting. If you could get info that would be great. Thanks, Lyle

Check out towards the bottom of this thread, WES999, and be sure you tell him I sent you.

That's my problem too, I wish they would make a pipe with the probe thermometer in. With my minor jobs I have problems drilling holes and not making them to big or to small so not much in doing something that could cause smoke in the house.

It's not really that big a deal . . . at least it wasn't with the probe thermometer I installed in my double-wall stove pipe . . . just followed the directions for using the two different sized drill bits and ended up with a nice, snug fit.

Nor should you worry about smoke 'leakage', since - with a fire going and draft established - a hole in the flue pipe will draw air in... rather than allow smoke out.

Especially with double wall but even with single wall I would definitely go for probe. The same reason you don't check the temp of an infant by placing the thermometer on their forehead.
