Temp difference from stove top to pipe?

[MikeP]

Just curious what difference in temperature other people have on their stoves from the stove top to the pipe? Reason I ask, my old stove, different house and setup, a Vermont Castings Madison (also a burn tube stove) would usually cruise in the 550 range on the top and be at 400-450 16" up the pipe. My NC-30 is currently sitting at 625 stove top, but the pipe is barely over 300. The hottest I have ever seen the pipe was just over 400 and that was at a 750 or so stove temp.

that's pretty much exactly what my 30 does.

Mine too. The pipe is about half the temp of the stove, which I consider a good thing.

SOOOO ................... is this the norm ? The pipe should be half the temp of the stove ?

My half round magnet Rutland reads 300 most of the time . Low range of the burn range .

To keep it higher requires a lot more air .

When it was cold out I was running the stove top at 650 and the pipe temp just below 500. Then after 10 minutes I would adjust the air and bring the pipe temp between 450-475. I had a good bed of coals so before I would reload we would let the stove top temp get below 500.

I have been home all day .... a little while back I filled it up with 2yo oak and a couple pieces of maple .

great fire , nice and warm out front ... dogs lounging one foot from the thing ..... Th pipe got up to just about 350 ! I cut the air back and its down to 250 with a glowing box slow rolling fire , bright , what looks like a perfect fire !

This stove is happy running in the low pipe temp range and i dont get it . 1000sf of living space is quite comfortable in the upper 70's .

I worry about mucking up the pipe and having a chimney fire !

Although I answered a post like this just a bit ago, I will state that the temperature difference varies....a lot. For instance, this morning when I got up I loaded the stove and the flue temperature was around 500 degrees when I engaged the cat. The stove top was around 300. Shortly after engaging the cat the temperatures did a flip flop. Now the two temperatures are 400 stove top and 250 flue. (btw, I only put in 3 very small splits this morning so that fire won't last long.)
