(54) Energy-saving water boiler


(57) A water boiler (10) includes a water storage tank (12), a heater (16), and a heat pipe unit (18). The water storage tank (12) includes a heating room (34), an outer water storage room (36), and an inner water storage room (40) between and spaced from the heating room (34) and the outer water storage room (36) in a radial direction. Outside water (56) flows from an inlet pipe (54) to the outer water storage room (36), and water (56) in the outer water storage room (36) flows into the inner water storage room (40) and the heating room (34) for storage. The heater (16) includes an induction coil (78). The heat pipe unit (18) includes a plurality of heat-transfer pipes (84). An upper segment (86) of each heat-transfer pipe (84) is arranged in the heating room (34), while a lower segment (88) of each heat-transfer pipe (84) is received in the induction coil (78). When the induction coil (78) turns ON, heat-transfer pipes (84) are heated to heat the water (56) in the heating room (34).
