Abstract
1,174,693. Water heaters; headers. H. VIESSMANN. 22 Jan., 1968 [21 Jan., 1967], No. 3338/68. Headings F4A and F4S. [Also in Division F2] A heat exchange unit in which water is heated in finned pipes 3 arranged in pairs, includes a header plate 1 to which is secured a U- section housing 6, the sides of which extend approximately to the edge of the plate whilst at the point where the walls merge into the arcuate end of the U they are spaced apart by less than twice the internal diameter of the pipes 3. Partitions (8, Fig. 2) are provided in the housing between each pair of pipes. The shape of the housing facilitates de-sealing by drill bits shown diagramatically in the drawing.
