<p>This invention relates to a heating element for heating a fluid. More specifically, the invention relates to a low voltage heating element, capable of heating a volume of liquid through the resistance of the liquid itself, particularly for the applications of heating water in geysers, swimming pools, spa baths and Jacuzzis. The heating element for heating a volume of fluid includes: one or more first electrodes connected to a first electrical terminal; and one or more second electrodes connected to a second electrical terminal, wherein the first and second electrodes are spaced apart in an alternating configuration with respect to one another thereby preventing any one electrode from being directly adjacent to another common electrode, the electrodes comprising an optimum electrode- surface-area to electrode-spacing ratio such that the heating element is capable of heating the volume of fluid as a result of the electrical resistance of the fluid, to the flow of electricity between the electrodes, while powered by no more than 70 volts for alternating current (AC) or 120 volts for direct current (DC).</p> |
