ABSTRACT:
A selected segment heating system including: means for heating a fluid; conduit means for conducting the fluid from the outlet to the return inlet of the means for heating through a plurality of areas; means, interconnected with the conduit, for moving the fluid through the conduit; gauging means for operating the means for moving to move a segment of the heated fluid in the conduit as far as the return point of the farthest area to be heated; and delay means for suspending operation of the means for moving for permitting a predetermined heat exchange to occur between the heating fluid and the air in the area to be heated. Alternately, there may in addition be a source of cooler fluid; valve means; gauging means for selectively interconnecting the means for moving with either the means for heating or the source of cooler fluid for establishing heated fluid segments in conduits located in the areas to be heated and unheated, cooler segments in the other areas; and delay means for suspending operation of the means for moving for permitting a predetermined heat exchange to occur between the heating fluid and the air in the area to be heated.
