A potable water dispenser includes a first reservoir for storing raw water, a second reservoir for storing boiled hot water, and a third reservoir for storing boiled warm water. The second reservoir is surrounded by the raw water in the first reservoir so as to effect a heat exchange therebetween. A condenser is disposed on the top end of the second reservoir. A heating device is interposed between the first and second reservoirs so as to vaporize the raw water from the first reservoir. Then, the vapor flows into the condenser so as to form boiled hot water which falls into the second reservoir. The boiled hot water will flow from the second reserovir into the third reservoir through a water duct so as to form boiled warm water. Two water tap units are respectively communicated with the second and third reservoirs so as to supply hot and warm water.
