PURPOSE: An instantaneous electric hot water boiler is provided to change water to high temperature water or hot water since a heat transfer resistor is inserted into an outer pipe and is heated to a given temperature quickly. CONSTITUTION: An instantaneous electric hot water boiler comprises a heat transfer heater and a pipe. The heat transfer heater comprises an outer pipe(100), an inner pipe(120), a heat transfer resistor(130), first and second coupling units(121,122), and first and second electrode units(140,150). The inner pipe is inserted into the first hollow of the outer pipe. The heat transfer resistor protects the outer surface of the inner pipe in a spiral shape. The first and second coupling units are bonded to one and the other ends of the heat transfer resistor. |
