February 4, 1928 WINNETKA TALK 55 CALIFORNIA WEATHER IN YOUR HOME All Winter Thru the Use of THE AMERICAN HEAT PRESERVER D TO INSTALL IT Simply remove section of smoke pipe and replace with American Heat Pre- server. Is made of special constructed steel pipe, of standard diameter and size, containing five semi-circular blades and adjusting chains all of which will withstand rust and heat for years. The Answer of Science to the Home-Heating Problem How much of the available heat units in fuel are you wasting? 50% to 909% Say Government Fuel Experts The American Heat Preserver stops this loss, as it insures complete combustion of gases and volatile matter in the fire pot of your heating plant, thus generating from 11,000 to 14,000 heat units per pound of free burning coal or coke, instead of from 3,500 to 4,500 heat units as now. The American Heat Preserver installed in the smoke stack of your heating plant will insure uniform heat in the home at all times within a variation of five degrees, because the fuel burns slowly and completely. The American Heat Preserver means less fuel to buy, and fewer ashes to carry out. The American Heat Preserver works like magic on any furnace, boiler or stove. The American Heat Preserver will pay for itself in fuel saving in one season, and last for years. execurive ormces EVANSTON SRANEN NILES CENTER smANCH DeenriELo sRancH Article from The Black Diamond, | memes tour ee. | inns, odie vr ST sue cite.
