1. A control system for a bathing unit, said control system comprising:

  • a heating module including;

    i) a body defining a passage through which water can flow;

    ii) a heating device operative for heating the water that flows through said body;

    a thermal element mounted in thermally conductive communication with water flowing through the body of said heating module;

    a heating module controller operative for controlling the heating device of the heating module to cause said heating device to acquire either one of a heating state or a non-heating state, said heating module controller being further operative for;

    i) causing said thermal element to acquire a certain temperature condition;

    ii) obtaining temperature information associated with said thermal element, said temperature information being distinct from a water temperature associated to the water that flows through the body of said heating module;

    iii) detecting at least in part based on said temperature information associated with said thermal element the sufficiency of water flow through said body.
