Furnace.—There are two ways of employingfurnace heating, namely, through the gravity andthe fan system. In very small buildings only, orwhere certain conditions do not permit, is it ad-visable to use the gravity system. The fan sys-tem is always preferable, but where a lack offunds does not permit, or where ready power foroperating fans is not obtainable, the gravity sys-tem must necessarily be resorted to. Such grav-ity system must depend for its successful opera-tion upon the planning of the ducts and the di-rection of the winds. With the gravity systemthere are times when strong winds from certaindirections may prevent certain rooms from beingheated. With the fan system the air may be 149. 150 Heating and Ventilation forced into all rooms even against outside windpressures. The furnace fan system, employed in the largerbuildings, usually proves successful. The effi-ciency here, like in all heating plants, however,rests mainly upon the proper planning and in-stallation of the system by a reliable contractorand one who is familiar with this class of schoolwork. It is very essential in this class of heatingsystems that all joints in the furnaces shall bemade air tight and thus dust and gas proof. Steam Heating.—The popularity of steamfor the heating of school buildings is due to avariety of causes. Primarily, it is cheap to installand eminently serviceable. On account of theintensity of steam heat much piping or radiatingsurface is not necessary. Single piping through-out is only necessary, with one series of returnsin the basement. Unused portions of the sys-tem can be shut off withou
