radiators

Heating devices that transfer heat from circulating water, steam, or another heated substance through a large metal surface.

A radiator is a device which heats its environment by passing pumped water, steam, or other substance through coils with a high surface area. Heat passes through the metal surface to the room by convection and thermal radiation.

Water is one possible heat-carrying substance rather than the only one. Steam and other substances are also included in the definition.

The radiator transfers heat into the surrounding space. Its presence does not identify the fuel or other source used to heat the circulating substance.
