<p>A vertical cylindrical storage tank for hot water comprising an inlet diffuser fitting connected to an inner end of a cold water inlet tube located at a region of discharge of cold water into a lower portion of the tank. The diffuser has plural spaced distribution openings, each smaller across its transverse axis than the diffuser inlet but in total area of openings, much larger than the diffuser inlet. The spaced openings are substantially uniform and aligned upon assembly to deliver a discrete layer of cold water within the lowest portion of the storage space. This enables incoming cold water to be dispersed from the distribution openings uniformly in plural streamline flows into the storage space below the diffuser to minimise currents that cause mixing of hot and cold water in the tank so that a greater proportion of the tank's capacity can delivered continuously at the outlet as usefully hot water.</p> |
