Does flue color affect heat?

[vwerner@hotmail. om]

I currently have a shiny SS stove pipe. Have heard some claim that painting it black will improve its ability to radiate heat. Is this true, and if so, does it make a big difference ?

Also how on earth would the black paint make a difference?

Black absorbs radiant heat and is a good emitter as well. But normally keeping the heat in the stove pipe instead of radiating it is a good thing with a modern, efficient secondary burn stove because the flue gases are cooler. Keeping the flue gases above 250F at chimney exit will prevent creosote condensation and improve draft.

Some people confuse "black body radiation" tables with ideal heat transfer conditions.

Heat with the stove, not the pipe. That being said, I doubt painting it black would make a nickels worth of difference in heat. Do what you would like for ascetics.

Thanks for everyone's responses.

I think the heat difference won't even be noticeable . But I agree with begreen. Usually you want the stove pipe to be as hot as possible so I wouldn't suck heat from it unless it was for looks only "aesthetics "
