A very quick question. My copper rad is painted black, just like most radiators. In your opinion, how much effect do you think the paint has on the thermal conductivity of the copper? Wouldn't we be better off if we removed the paint? Just a thought.

Hi Wayne,
Actually, I do not know what the real effect of paint has on the heat transfer capability of the radiator. It would seem that any coating would reduce the transfer rate unless this coating had a equal or better thermal conductivity rate.
As most black enamels these days are polymer based and use carbon black as the pigment, I would think that they would reduce the thermal conductivity quite a bit.
But, I do not have any good data on this. I do know that the F! radiators are not painted other than with a small logo in the fin area.
