The present invention relates to a structure of an industrial water heater for preventing an accident which is easy to design and can prevent fire and resulting damages. More specifically, the present invention can promote ease of production by consisting a heater rod of a water heater with an outer tube and an inner tube, having a sensor for temperature detection inside of the inner tube, equipping the sensor for temperature detection down to a pig tail-shaped heating unit in the lower portion of the inner tube, and making the an additional sensing rod for temperature detection not necessary. In addition, safety can be achieved by having a grounding bracket for grounding a control unit, the temperature detection sensor equipped inside the inner tube, and the outer tube. |
