PROBLEM TO BE SOLVED: To solve the difficulty with prior art that since an electric heater is used for a boiler, an apparatus is not installed at a position where commercial power supply is not available, and hence a method is proposed, which heats a heat exchanger directly or indirectly using a combustor for a heater, but the construction has another problem where the life of a power supply for use in the control for the combustor is short. SOLUTION: There are provided standby operation detection means 29 for detecting that a combustor 13 in a standby operation, and a timer section 28 where once the standby operation detection means 29 enters the standby operation is detected, it delays an interruption of power supply to the combustor control means 25. Hereby, wasteful use of electric power is eliminated, and liquefied gas vaporizing apparatus with the long power supply life is ensured.
