Chimney Pipe hotter than pipe exiting stove

I have a juniata Reading Coal Stove. I feel like I could possible be loosing heat out of my chimney. I do have a barometric damper. I also have coal trol thermostat hooked up. When the stove calls for heat the damper opens very far. No matter what though the chimney pipe is always hotter than the pipe leaving the stove carrying the hot air. At some points that chimney pipe is scalding hot. Is this normal?

Yeah , warm air to the house isn't gonna be nearly as hot as flue gases in the flue pipe. My flue pipe runs around 150 at idle and my warm air going to the house is about 105-110 degrees. This might seem counter productive but remember, there is a huge volume of warm air going to the house where there is only a very minute volume of hot flue gases.

In extreme circumstances such as accidentally leaving the ash pan door open, the flue pipe can reach 900 degrees.
