[0003] Accordingly, a conventional instantaneous electric boiler first comprises a heater consisting of a single vertical pipe with a built-in electric heating rod, which supplies heating water to the indoor heating pipes by passing direct water through the vertical pipe.

[0004] More specifically, a conventional instantaneous boiler includes a heater and a control unit. The heater comprises a vertical pipe with a built-in electric heating rod, a direct water supply pipe connected to the vertical pipe, a pump installed in the middle of the direct water supply pipe to transport direct water, a water discharge pipe connected to a heating pipe connected to the direct water discharge side of the vertical pipe, and a temperature sensor installed in the middle of the water discharge pipe to detect the temperature of the heated water discharged from the water discharge pipe.

[0005] The control unit is connected to the pump and the temperature sensor, and is configured to receive real-time temperature data of the water discharge pipe from the temperature sensor, stop the operation of the pump if the temperature of the water passing through the water discharge pipe exceeds a set temperature, and operate the pump to move the water and heat the water if the temperature of the water passing through the water discharge pipe is below the set temperature.

[0006] Therefore, in a heater comprising a vertical tube containing a single heater rod that constitutes a conventional instantaneous boiler, if the set temperature of the heated water is exceeded, the pump can be stopped to prevent overheating of the water; however, the conventional instantaneous boiler had a problem in that no other effect could be expected other than the effect of preventing overheating only in a boiler having a heater comprising a vertical tube containing a single heater rod.
