The present invention relates to a boiler for saving power through a variable output voltage. The boiler comprises: a container having a space having a thermal medium stored therein and having an inlet where the thermal medium is introduced and an outlet where the thermal medium is discharged on one side; an electric heater positioned inside the container to provide a heat source with the thermal medium; and a circulation pipe of which one end is connected to communicate with the inlet and the other end is connected to communicate with the outlet to enable the thermal medium to circulate and flow therein. In addition, the boiler comprises: a temperature sensor measuring the temperature of the thermal medium stored in the container and transmitting measurement information of the thermal medium to a control box; and a control box comprising an input unit, a setting unit, and a power control unit. The present invention can improve user convenience and save energy in comparison with an existing boiler. |
