In Fig. 23 is shown five three-column radiators, varying in height from 20 to 45 inches. The sections of steam radiators are joined together at the bottom with _close-nipples_, so as to leave an opening from end to end. The sections of hot-water radiators are joined in the same manner, except that there is an opening at both top and bottom. Fig. 30 shows the openings of a hot-water radiator installed as _direct-indirect_ heater. Fig. 24 illustrates a special form of radiator that is intended to be placed under windows and in other places that will not admit the high form. Such a radiator as that shown in the picture is often covered with a window seat and in cold weather becomes the favorite place of the sitting room. Another special form is that of Fig. 25. As a corner radiator this style is much to be preferred to the ordinary method of connection; here the angle is completely filled--there is no open space in the corner. [Illustration: FIG. 22. FIG. 23. FIG. 22.--Single column steam radiator. FIG. 23.--Three-column radiators of different heights; for steam or hot-water heating.] Wall radiators such as shown in Fig. 26 are made to set close to the wall, where floor space is limited. They are particularly adapted for use in narrow halls, bathrooms and other places where the ordinary type could not be conveniently used. A radiator that will appeal to all neat housekeepers is that of Fig. 27. It does not stand on the floor as in the case of the ordinary type, but is hung from the wall by concealed brackets. The difficulty of sweeping under this radiator is entirely avoided. Fig. 28 is a radiator designed to furnish a warming oven for plates and for heating the room at the same time. It is sometimes installed in dining rooms.
