Its a case of using rads made of a metal that will not rust or you will get a gob full of hot rusty water.
Its not only that of course, you don't want electrolysis occurring either, this occurs between various metals depending on how far apart they are on the electrolytic scale. They can cause one another to corrode or one cause the other to corrode.
The water itself is also usually highly aggressive and full of oxygen and so prone to cause problems in the likes of iron rads.

Problem is hot water rads like hot water pumps usually cost a fortune.
