<p>A dispenser tap (10) dispenses boiling and cold water through a plurality of inlet pipes (18, 20, 21) in a main body (14). Each inlet pipe (18, 20, 21) is thermally isolated from the main body (14) by means of an air gap maintained by an outlet plug (30), an inlet plug (23) and a divider (24) in the main body (14). The tap cold water tube (20) may include a venturi type restriction (102) and bleed tube (104) on the outlet side of the restriction which drains the outlet tube (20) to prevent dripping when the tap is turned off. Water supply for the tap (10) may pass through a filter including a filter detection system (200) with a housing (202) having a switch (210) detecting the presence of a magnet (208) on a screw-in cartridge (204). Also disclosed is a filter exhaustion indication system (300, Figure 5) which is a microprocessor based system indicating when recorded flow times reach a predetermined amount. Also disclosed is a water dispenser (400, figure 6) incorporating the above devices and which includes a refrigeration system and a water heating device (402), in which the condenser coil (414) of the refrigeration system heats the source of water for the heating device (402).</p> |
