The heading radiator. Between utility and aesthetics Authors Francesc X. Barca Salom Institut d'Estudis Catalans Keywords: heating by hot water or steam, radiators, finned tubes Abstract In the mid-nineteenth century, when centralized heating began to be applied in some buildings using steam as a fluid, the radiator was used as an element of heat emission at the site. The centralized heating system requires a generator, which is usually a boiler where water or steam, is heated. This fluid, circulating through a pipe circuit, must transport the heat to the place where it must be heated. To facilitate the transfer of this heat to the air, one emitter would be necessary. In the first years of this technology two types of emitters were used: the fins tubes and the radiators. In this paper we will try to see what the origin and evolution of radiators was as well as the aesthetic and hygiene concerns that were generated because of its application.Key words: heating by hot water or steam, radiators, finned tubes Author Biography Francesc X.
