1811 Jrnl. Nat. Philos. Aug. 262 Radiation from other bodies, that is radiant culinary heat, is very different: the radiator is in a state of vibration; this vibration is communicated to all surrounding bodies, the most important of which is the atmosphere.

1836 W. T. Brande Man. Chem. (ed. 4) 516 The polished metals are very imperfect radiators and receivers of heat.

1879 R. A. Proctor Pleasant Ways Sci. xvi. 364 Glass..is a good radiator, so that dew is freely deposited on glass objects.

1927 Physics Abstr. A. 30 415 (heading) Performance and design of sound radiator consisting of an acoustic transformer and horn.

1977 G. Porges Appl. Acoustics xii. 140 A dipole is a less efficient radiator of sound than a monopole, and a quadrupole is even less efficient.

1991 Economist 21 Dec. 121/1 A perfect radiator, which physicists confusingly call a ‘black body’, gives off a characteristic spectrum of radiation.

2. A device for heating a room, consisting of a metal enclosure (typically a flat panel or a compact set of pipes) through which hot water, steam, or hot air is circulated; any heater that depends on the contact of the surrounding air with a heated surface.night storage, panel, skirting radiator, etc.: see the first element.

1838 Daily Whig & Courier (Bangor, Maine) 7 Nov. 3/1 The chief peculiarity of this stove, consists of substituting for the open pipe usually employed to distribute the heat generated by anthracite coal, an apparatus called a radiator, which..has an effect in absorbing and distributing the heat equal to that of a very long pipe.

1891 W. P. Buchan Ventilation xv. 166 The so-called steam or hot-water ‘radiators’ heat principally by conduction, as may be easily proved by suspending one thermometer, say, a foot high right above the ‘radiator’ and another right in front of it and six inches from it.

a1910 ‘M. Twain’ Europe & Elsewhere (1923) 178 The German stove..is lovely,..compared with any ‘radiator’ that has yet been intruded upon the world.

1966 N. Chapman Heating 37 A storage radiator..provides the most comfortable conditions in a room early in the morning because the air is warmer from the heat given off during the charging period.

1985 D. Holloway Which? Bk. Plumbing & Central Heating xiii. 155/1 You can now re-fill the system,..adding a corrosion proofer such as Fernox—this is very important in a system containing steel panel radiators which, under certain conditions, can corrode very quickly.

2006 Guardian 13 Apr. (Technology section) 5/1 Once the fluid being pumped has forcedly warmed your radiator, the heat rises off it passively—that is, by natural convection.

1973 W. E. Kock Radar, Sonar, & Hologr. ii. 42 In radars and sonars, this ability to steer the beam electrically, that is, without moving the radiator, permits much larger arrays to be used.
