Default Why are radiators made of cast iron

Nothing there says that radiators get hotter than what's circulated through
them. Do you contend that they can?


Where on earth did you get such a notion that any other poster had any
idea they get hotter than supply?

All he said was that they are hot surfaces and small persons should be
kept away -- which is all true (particularly if steam heat as opposed to
hot water, the surface temperature may be pretty hot on full flow).

Hot water in a tub isn't any hotter than the water out of the water
heater, either, but it can surely scald (particularly young, tender skin).

Typical hot water heat may be in the 180F max range while steam can be
around 215F--that's plenty warm enough to say "ouch" even giving a few
degrees for radiator surface temperature and distribution drop as
opposed to steam outlet temperature .
