According to the present invention, a method for controlling the temperature of hot water by operating a circulation pump includes: a step of determining whether a user is using hot water; a step of determining whether one of the operation modes of the circulation pump is selected; and a step of operating the circulation pump to circulate hot water from the outflow tube to the inflow tube when a user is using hot water and selects one of the operation modes, wherein the circulation pump is disposed on a bypass tube connecting the inflow tube, through which source water flows, to the outflow tube, through which heated water is discharged. Accordingly, temperature deviations in the hot water discharged from a water heater can be reduced. |
