1. An apparatus for determining time remaining for fluid flow at a temperature from a fluid outlet [14] which receives fluid from a fluid source [18], comprising:

  • a first temperature sensor [22] for sensing fluid temperature at a fluid outlet [14];

    a second temperature sensor [34] for sensing fluid temperature at a fluid source [18];

    a communication link [29]; and

    a controller [38] in communication with said first temperature sensor [22] and said second temperature sensor [34] via said communication link [29], for comparing sensed fluid temperatures to determine time remaining for fluid flow at a temperature.
