An instantaneous water heater using near infrared ray is provided to improve water leakage prevention in a hot water pipe by reflecting heat of near infrared lamps to heating pipes. An instantaneous water heater using near infrared ray comprises a cylindrical casing(21), heating pipes(30), and near infrared lamps(40). The heating pipes have water inlet and outlet ports(31,32), and are received in the casing. The water inlet and the outlet ports are protruded from the casing. The near infrared lamps are received in the casing to emit heat by power supply. First individual reflecting pipes(35) are mounted around the heating pipes to reflect the heat of the near infrared lamps to the heating pipes. Second individual reflecting plates(45) reflect the heat around the near infrared lamps to the heating pipes. An insulating layer(22) is arranged on the inner wall of the casing, and a main reflecting plate(23) is mounted on the insulating layer. |
