When radiators in a hot-water system develop banging or hammering noises the problem is most often due to trapped air that cannot get out. Air gets into the system from the fresh water that is periodically added to the system (usually automatically) to replace water that evaporates or leaks out. The trapped air keeps the radiator from filling all the way with hot water, sometimes causing a pounding noise and almost always keeping the radiator from heating all the way across.
