Show Fan Used in Heating System Gives Results Discussing the value of a current of air In the home and the use of a fan in connection wilh the heating system, a writer in Building Age, after asking ask-ing how valuable Is a current of air. says: "By it the life stream is purified, puri-fied, health Is restored to sick bodies, and maybe even to sick souls by It heat is carried from its point of origin to the place where It is wanted ; noxious nox-ious gases are dissipated; the new building is dried- out ready for occupancy occu-pancy ; the fumes of paint and varnish are driven away. "Many a man has had the Idea that a fan Inserted sr mewhere In his heating heat-ing system woult' change It from sluggishness slug-gishness Into a'tivity nnd give him better results for his fuel money. Some have tried It in a home-made way and secured results commensurate with the degree of care given to the Installation. Then commercially-minded men set to work on the problem In a larger way and developed means for securing forced draft In the ordinary house-heating system to be controlled at will. ' "Heating experts have found by experiment ex-periment that fan-driven air In the furnace not only obtains more efficient ' combustion of fuel but gives better I ventilation by circulating the air In ' all rooms and breaking up cold areas. These results ran be secured, ton. with i the use of cheaper grades of fuel than ' would otherwise he required where j only natural draft is used. "The Universily of Michigan, which ' has been carrying on extensive tests in I household healing under the leador-' leador-' ship of Prof. .1. I-:. I'tiswiler. has found that the fan biower Is tin important part of any mo'l'-ni heating sjstcm. "While we cannot yet announce final results." said Professor Knswi'er.
