A smallopening at the top of the window is always needed forfresh air, even if it is cold air. Ventilation and Hot Air Heating. — When heatingwith hot air, the problem of ventilation is half air is heated, and driven into the rooms; butwhere does it go after it becomes foul? It may be suckedinto another room, or up or down a stairway. Possibly. Circulation of Air with a Stove 38 HEALTH IN HOME AND TOWN there is a fireplace which will draw it up the chimney,or perhaps there is an opening into a ventilating flueor shaft. Circulation of Air from Radiators. — When heatingwith hot water or steam, heat comes from the radiatorand no fresh air is admitted through the heating ap-paratus. Air is sucked up from the floor and heated over and over air, even if cold,must be admitted byway of the windows ifno other means of ven-tilation is provided.(See the figure.) Ventilating Shafts.—The fireplace and itsopening or flue offer thebest way of withdraw-ing foul air from a living-room or bedroom. In manyinstances its use for ventilation and decoration are itsonly excuses for being used so extensively. A ventilat-ing shaft may be built in any partition, where afireplace would be impossible.
