An instantaneous water heater is provided to secondly heat water introduced into a housing of the water heater by a ceramic heater, so water with a constant temperature is supplied to users, by arranging first and second sensing units outside the housing. An instantaneous water heater(100) includes a housing(4) having an inside with first and second packing members and a ceramic heater and an outside with a fuse(F), a first sensing unit(7) coupled to the housing and equipped with a flow sensor and a first temperature sensor(6) connected to the flow sensor, and a second sensing unit(11) coupled to the housing and equipped with a second temperature sensor(9) having a connection pipe and an automatic temperature controller(10) connected to the second temperature sensor. The instantaneous water heater further includes a first cap(20), a second cap(30), and a control unit(40). The first cap is coupled to one side of the housing, and has an inside with a third packing and one end with a connection hose and a connection part(23) connected to the connection pipe of the second sensing unit. The second cap is coupled to the other side of the housing, and has an inside with a fourth packing and one end with a third temperature sensor(32) and an outlet pipe(33). The control unit controls the ceramic heater, the first sensing unit, the second sensing unit, and the third temperature sensor of the second cap. The control unit includes a micro computer, a breaker, and a triac. |
