A water purifier includes a water outlet discharging purified water therethrough, a first temperature sensor to sense temperature of the purified water, an induction heating module provided with a working coil forming magnetic field according to a current flow, and a hot water tank heated by the magnetic field and receiving the purified water to deliver to the water outlet, and a controller to control the current to flow on the working coil while the purified water is transferred to the water outlet through the hot water tank in response to a water discharge request, wherein the controller controls the current value flowing on the working coil, such that purified water lower than the target temperature is discharged until a predetermined time point from when the water discharge request is applied, and purified water higher than the target temperature is discharged after the predetermined time point.
