What a convenience during the frosty mornings of late autumn or the cold, damp days of early spring, when warmth is usually needed for only a few hours a day, to secure just the right amount with the turn of a switch. Then, too, there is often a room, hall or sun parlor to which the Corto Electric Steam Radiator can bring the additional warmth needed for complete comfort during especially severe weather. It is also an ideal solution of the heating needs of summer homes and homes in the south and on the west coast where warmth is not needed regularly. cA ‘Radiator of “Distinctive “Beauty Designed by a French Engineer imbued with the traditions of atartistic race, the @ortovis a radiator of ‘classic beauty... “ltis the delight of both interior decorators and discriminating home-owners, for its graceful Gothic lines readily harmonize with any interior, and it occupies a third less space than the usual radiator of equal heating surface. It may be painted or enameled in any color to match its surroundings, and may also be obtained in a glistening white porcelain enamel to match bathroom fixtures. five Quick Heating Because of its slender columns, the Corto Electric Steam Radi- ator has a very small water content in proportion to its surface. This is a great advantage, for the small volume of water is quickly heated, and warmth is given off very shortly after the current is turned on. cA (up of ‘Water a Year Its Only “Requirement A single filling of water is the only attention the Corto Electric Steam Radiator needs for an entire year of service, for in this time it evaporates less than a cup of water. Operation is simplicity itself: the control, an ordinary three- heat electric switch, need only be turned to “high,” “medium,” or ‘low,’ for the amount of warmth desired. SIX CHealthful, Effective, Clean, and Safe Unlike both gas and electric heaters of the radiant type that parch the air by intensive heating and heat only the space directly in front of them, the Corto Electric Steam Radiator warms the air gently and evenly in large volumes and circulates it throughout the room. No ashes, soot, noise, odor, or excessive moisture are con- nected with its use. No exposed hot parts endanger members of the family or surrounding objects; water splashed on it does no harm. “Readily eAloved to cAny “Room The Corto Electric Steam Radiator is much lighter than the usual type of radiator, and as no flue or piping is required, it may easily be moved to any room with a proper electrical connection. In the summer, when it is not needed, it may be removed and stored. This portable feature makes it especially suitable for use in buildings under construction and on yachts and ships. Sever_s One Sundred “Per (Cent Efficient This unique heating unit operates at the absolute maximum of efficiency—100%. Every unit of electricity supplied to it is trans- formed into heat. As current is used only when warmth is actually needed, and 50% and 75% less is used on medium and low than on full current, operating costs are moderate. A few cents a day will provide all the warmth necessary to remove the chill from bedroom, bathroom, or favorite corner. A table of operating costs for different current rates is given on page 12. eighm~ Ghee CORTO ELECTRIC STEAM RADIATOR is Especially Useful in.

This construction provides two joints instead of the usual one, and is the safest and most satisfactory of radiator connections. It is an exclusive feature of American Radiators. The immersion unit is of especially rugged construction. It is of a standard type that has been in use for many years, and will last indefinitely. Equipmenm~ Equipment consists of filler and cap, safety valve, air vent, heating element, three-heat electric switch, and five foot cord. The switch is regularly clamped to the radiator, but may be fastened to a wall, if desired. ten SIZE REQUIREMENTS The following table gives factors by which to multiply wall and glass surface and exposed volume to determine watts required for heating to seventy degrees (without other source of heat) for any outside condition.
