Heating, Lighting, and Refrigeration: Registers

Registers set in the wall naturally receive less dust from sweeping than floor registers do. They also give the warm air a somewhat better circulation.

How to Regulate Hot Air.-Hot air is a misnomer. Overheated air is detrimental to health and also injurious to woodwork and furniture. The term “ warm air" is preferred by most authorities, and the best results are secured by having a relatively large furnace that, by delivering a large quantity of air at a moderate temperature, will heat the house comfortably in the coldest weather. The air should not be delivered at a temperature greater than 120°, and under no circumstance should the fires be allowed to rage until the fire box is red hot.

To Overcome Dryness. - The dryness of the atmosphere caused by the warm-air furnace may be overcome by keeping a supply of water in the receptacle usually furnished for that purpose inside the jacket of the furnace; or by hanging a small tin pail of galvanized iron from a hook below HEATING, LIGHTING, AND REFRIGERATION one or more of the registers in the room, so that the current of air therefrom will receive a small amount of moisture.

Hot Air - To Prevent Waste. - A great saving can be effected by casing the jacket of the furnace and the hot-air pipes with several thicknesses of asbestos paper to prevent direct radiation in the basement. Heat which would otherwise be wasted may also be utilized by the addition of a hot-water attachment. This combination of the hot-air and hot-water systems affords, perhaps, the greatest 0 GLALU "The Same Flue Will Serve Two Registers." possible economy in fuel. The hotwater piping may be used in distributing the heat to any parts of the house not equipped with the hot-air system. When possible, the hot-air flues should be so adjusted that the same flue will serve two or more registers. Thus, by closing the register in the lower rooms, the heat can be diverted through the same flue to the upper part of the house, with the least possible number of pipes and waste of heat.
