A hot water dispenser is provided for dispensing a selected volume of water at a predetermined water temperature. The dispenser has a body defining a predetermined sized cavity having an inlet for receiving cold water and an outlet for dispensing hot water. A heating mechanism is disposed within the body for heating the water contained within the cavity. A manually operable timer switch is operated to energize the heating mechanism and to select a time period for maintaining the heating mechanism energized. This selected time period determines the selected volume of heated water dispensed. A thermally responsive mechanism enables dispensing water from the outlet responsive to the predetermined water temperature of the heated water.
