If the tubes have never been red you likely have not taken full advantage of your stoves potential but no knowing the model that is speculation. Those tubes are stainless and can take the heat w/o a problem. It would take a micrometer to identify the change in size when hot like that and I'll let you reach in to measure them :)

Stove is a Hearthstone Heritage. The tubes may be stainless, but my arms aren't, so I'll pass on the measuring.
 
Mine glow on almost every reload after it gets hot and I close the air to 75%
So if your tubes are glowing, do you have a flue thermometer or probe and know what is happening at that time in the stove pipe? Just wondering.

At this moment, at our house, it's 9F out, 72F in. Reloaded about an hour ago, mostly 3y.o. oak, pretty full load, on a fair coal bed. Tubes are glowing some and shooting out like gas burners, primary air is all the way closed, stove top is 540F (rising slowly), probe shows 750F (falling slowly).

So what's your secret for keeping your flue temps that low?
 
What stove do you have?
I have a Drolet Eastwood 1800. I have a probe thermometer mounted in double wall pipe about 16" from the stove top and I try to run the stove in the 500-700 F range. The secondaries do burn the smoke as they should and Maybe they do glow a bit but the flame might be too bright to notice it. This image is from SBI.

Thanks.
Don't have a stove thermo yet, but I was a little concerned when mine glowed red and I could barely touch my bare hand to the flue, Vogelzang Durango...From working in the kitchen I knew what a 550 deg pan felt like, so that was the comfort I gave myself, if I can touch it, it must not be 550-600 yet.

After feeling all the heat when choked down all the way, I was really glad I didn't get a used 'old' stove, and lose all that heat.

I don't have a probe I have single wall pipe with a magnetic thermometer. When the secondaries are glowing the stove is generally at it's hottest point after a reload. Stove top is usually between 600-650 and the flue reads around 400-450. After another hour or so the stove top is about the same but the flue drops down a bit to normal around 325-350.

Thanks a lot! That's helpful info. As I have double wall and don't have a probe(yet), I was kind of blind regarding the flue temps. I was assuming that the flue at that point would be about as hot as the stove top. Again, thanks. I do appreciate this forum.
