Provided is a drying heater, a heating unit for drying laundry using the same, a drying control system and control method thereof that reduces electric power consumption of the drying heater to supply high temperature dry air to the inside of a drum in a washing machine or a laundry drying machine, to thus simplify structure of the drying heater and reduce a manufacturing cost. The drying control method includes the step of applying a first electric power from a first drive power supply to a drying heater when a drum internal temperature is lower than a preset temperature, and applying a second electric power from a second drive power supply which is relatively smaller than the first electric power to the drying heater when the drum internal temperature is higher than the preset temperature. The drying heater includes a surface-shaped heat generation member made of a low thermal density strip style metal thin plate.
