It is in fact the best radiator.
Dull black is the best absorber and emitter. Then shiny black, followed by white, then silver.
While the best reflector goes the other way around (silver's the best, then white, followed by shiny black, then dull black)

How does the heat energy get from the hot water to the outside of the radiator?
The hot water is in contact with the metal casing of the radiator, so that metal radiator takes some heat from the water. The heat then passes from the inside metal of radiator to the outside metal of the radiator through convection. The outside metal of the radiator then passes it to the air that is blowing by it outside.
In general good absorbers of electromagnetic radiation are also good?
Yes, Good absorber of heat are good emitters of heat. And in both the way rate is same. This is Kirchoff's Law.
How much heat is needed to get a bolt out?
Quite a bit--sometimes you need to heat the thing to a dull red.
Why do you blacken the outer surface of a solar cooker?
It is because black colour is a good absorber of heat
Why do coils of room heater have shining coverd metal surface?
Coils of room heater have shining coverd metal surfaces to radiate the maximum amount of heat possible with the current structure of its radiator.
Is white surface good radiator of heat?
A white surface is a good radiator of heat.
Is dull black surface is a good radiator of heat?
Yes, it is. As dull and black surfaces are the best emitters as well as the best absorbers of radiation. Hope my answer is good enough to be stand up your question needs.
What is the difference between a good radiator of heat and a good reflector of heat?
heat absober absorbs heat & refelector reflect it
Is the good radiator of heat a shiny silvered surface or white surface?
Shinny silverd surface
Why are the inner surface of a solar cooker painted black?
for it to absorb heat because dull colors are good absorbers of heat
Which color is the best absorber and emmiter of heat?
Dull black is the best heat radiator.
Which surface radiates heat the best?
Dull Black Surfaces
What surface are bad radiator of heat?
white
What material is a radiator made of?
Material with low specific heat capacity and with blackened surface are good for radiators.
Which is the best absorber of inferared radiation heat a dull surface or a shiny one?
A dull surface will absorb infrared best, but it needs to be dull at infrared wavelengths. Do not judge the infrared behavior by the visible performance.
Why is there a shiny surface at the back of the radiator?
The shiny surface is a reflector, to reflect the heat outwards towards you.
What is the function of fins in radiator and condenser?
More surface area to dissipate heat, the more exposed surface of a material the more place to 'let out' the heat
