The most outstanding results of the many years of investigation at the University having a direct value tO the industry and home are: ( 1 ) The determination o\ the performance characteristics of furnaces oi various types, that is, the relation between combustion rate, draft, efficiency, heating capacity, and air temperatures throughout the system. (2) The determination of the heat carrying capacity of first, second, and third lloor leaders and stacks. This makes it possible to design a warm-air system in accordance with the heat loss from a building, thus placing the warm-air plant on the same basis as a steam or hot-water plant. (3) The positive demonstration in the Research Residence equipped with a modern furnace heating plant that a properly designed warmair system is a successful and satisfactory method of heating the better as well as the smaller class of American homes. (4) The determination of the proper type of covering for basement pipes in order to reduce the heat loss from such pipes. I 5 ' The determination of the principal sources of heat loss from a furnace and the recommendation of means by which such losses may be minimized. (6) The determination of the relative effectiveness of several types of water pans when used as humidifiers. (7) The investigation has also made possible the formulation of a Standard Code for installation which has been accepted by the American Society of Heating and Ventilating Engineers and other national organizations. The adoption of the Code is of the greatest value to the home owner and the manufacturer and the installer. Direct S t e a m a n d H o t - W a t e r H e a t i n g S y s t e m s The University of Illinois has, likewise, pioneered in direct steam and hot-water heating work. The effectiveness of various types of direct steam and hot-water radiators in heating rooms has become a matter of great importance n v that so many types of radiators and enclosures are available. R diator manufacturers, heating contractors and engineers, as well as buildii nvners, are seeking for definite information concerning this 1 mat >o that the most satisf tory and efficient types of room heatin. be elected, and properly placed or installed. Thi bulletins have already been published by the University and contain much information on the best and most economical method heating rooms b direct radiators. The results have been* widely Cll llated and quOt< | in the te. hm il pr< s, and h a \ e made it tieCeS I 13]
