A device for maintaining the internal temperature of a pressure vessel. The device includes a pressure vessel equipped with a main heater for heating test water to a predetermined test temperature and for maintaining the predetermined test temperature, a preheater for primarily heating the test water to the predetermined test temperature before the main heater heats the test water, and a heat exchanger including an feed pipe for feeding the test water heated by the preheater to the pressure vessel and a discharge pipe for transporting the test water discharged from the pressure vessel, in which the feed pipe is disposed inside the discharge pipe.
