Abstract: An instant water heater utilizing positive temperature coefficient plastic electrically conductive material structures for electrodes. The heating of the water is not generated by the electrodes, but instead by the resistance of the water to the electrical current flowing between them. The material of the electrodes undergoes a phase change at certain temperatures when whereby it converts from electrically conductive to electrically non-conductive at a predetermined temperature. The output temperature of the water is determined by a combination of the area of the electrodes that confront one another, the water's conductivity, the flow rate of the water and the current limiting capability of the conductive electrode materials positive temperature coefficient, which reduces or stops the heating of the water when the intended water temperature is achieved.

At least one of the shelves has a hollow interior or chamber. Disposed in the chamber is at least one electrical heating element, where the power supplied to the heating element is regulated by a control system. As controlled, the electrical heating elements provide sufficient output to the tower casing which result in a substantially constant temperature throughout the passage.

An electrically resistive heating element for heating the fluid can be molded into the chamber to heat the fluid from room or ambient storage temperatures to a normothermic or body temperature of the patient. A probe of a temperature monitoring element can be used to monitor the temperature of the fluid exiting the chamber. In another embodiment, this information can be relayed back to a controller for controlling the power to the resistance element and hence, the temperature of the fluid. In still another embodiment, an infrared temperature sensor can be used for monitoring the temperature on the fluid exiting the chamber by scanning through a window in the outlet port of the chamber or elsewhere in the fluid line.
