I believe the difference in energy radiation is insignificant between a 
black and a shiny radiator.

Energy absorption is very different though as much of the energy is 
reflected off of a shiny surface while a dull black surface absorbs lots 
of energy.

I think the confusion lies in the term "Black Body Radiation", 
http://en.wikipedia.org/wiki/Black_body. The only significant factor is 
the temperature of the radiating body.
