Abstract

An on-demand hot water dispenser () with a source of hotter water () at a preselected relatively elevated temperature () and a source of cooler water at a relatively non-elevated temperature compared to the hotter water () has an outlet dispense valve () connected with both the hotter water source and the cooler water source through a common mixing chamber () to selectively vary the temperature of the mixed water being dispensed. The cooler water source () is connected to the outlet dispense valve () through an electrically controlled proportional valve () with a variable flow rate that is controlled during dispensing and mixing in accordance with a comparison between a selected one of a plurality preselected temperatures stored in a controller () and a sensed temperature () of the mixed water in the mixing chamber () to maintain the mixed temperature of the water being dispensed at a preselected temperature on a real-time basis.
