Black/white radiator vs white/black wall: radiation

  1. Jan 25, 2015 #1

    Situation A: Black radiator in a room with white walls.
    Situation B: White radiator in a room with black walls.

    Which one is the most efficient situation?

    I know that convection is dominant if you look at a radiator, but i would like to know the answer in terms of radiation.

    Thank you :)

    Efficient for what?

    Efficient in terms of maximum heat transfer from the radiator to the wall. Sorry I forgot to mention that.

    I assume that you don't want the walls to get warm?
    This reads like a test question. What are your thoughts on the matter? (Before we kick in with a free answer to your homework(??))
