Fig. 22 is a radiator made up of eight single-column sections. 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.

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.

The ordinary method of heating by the use of radiators is known as the direct method. The air is heated by coming directly into contact with the radiators and distributed through the room by convection. If the arrangement is such that the air is brought from outdoors and heated by the radiator before entering the room, it is called the indirect method of heating. Such an arrangement is illustrated in Fig. 29. The radiator is located beneath the floor, in a passage that takes the air from outdoors and after being heated, enters the room through a register located in the wall.
Fig. 30 is still another arrangement known as the direct-indirect method of heating. The radiator is placed in position, as for direct heating, but the air supply is taken from outdoors. The radiator base is enclosed and a double damper T regulates the amount of air that comes from the outside. When the inside damper is closed and the outside damper is open, as is shown in the drawing, the air comes from outdoors and is heated as it passes through the radiator on its way to the room. If the dampers are reversed, the air circulates through the radiator as in the case of direct radiation.
