Is it possible to have a hot stove and cool flue because of poor conditions (whatever they may be) as one might think the stove and flue would both be cool under less than ideal conditions.

Perhaps with soapstone stoves - my stove holds its temp for a long time - some hot coals right now with surface temp of just under 300* and internal flue temp of 320* or so. I bet that my stack becomes cooler than my stones before long. But, with steel or cast, I'm guessing the this is less likely to happen, and stack should be hotter than (or perhaps nearly equal with_ the stove temp. Smarter folks will correct my thinking!

probe reads 300 to 380. i have a probe and a surface thermo surface one reads 200 to 250.BeGreen said:corey21 said:surface thermo probe above reeds 300 to 380.
Is this a surface thermometer? If so, this translates to 450 to 570°F interior flue gas temperatures. These are totally normal flue surface temps.
(If this is a surface thermometer and not a probe thermometer.)
A little cool? I can get mine to 200 (surface) on paper and sticks.BeGreen said:Ah, best to describe it as a probe thermometer then. It's a little on the cool side, but not unusual for shoulder season burning. Give it a little time to learn your stove and wood better. When the temps drop the draft will be stronger and if the wood is under top cover, it will be a bit drier too.
i think i should relax then. i am concerned about creosote but it was at those temps last night and i had a great secondary burn going.BeGreen said:Ah, best to describe it as a probe thermometer then.

At those temps I think you might have a cresote problem but maybe it will get better the colder it gets. My flue temps will get away from me if I do not watch it.corey21 said:i think i should relax then. i am concerned about creosote but it was at those temps last night and i had a great secondary burn going.BeGreen said:Ah, best to describe it as a probe thermometer then.

BeGreen said:I believe that last winter Condar had posted on their site that the flue gas temp was ~1.5X surface thermometer reading.
Todd said:Maybe Begreen's antique probe reads 50% since it's so old?
oldspark said:Not sure I care about the internal temp, surface temp is what I and the house interface with, the gas temp could be 5000 degrees as long as the outside is where I want it.
Todd said:But you should care because you don't want to wreck your liner with a continuous burn over 1000 degrees internal which would be about 500 for your external thermometer.
I was thinking the same thing but it does seem to be a little on the low side, keep an eye on the chimney for creosote.corey21 said:My probe seems to be on target it reads 380 when surface thermo is 240.
