PROBLEM TO BE SOLVED: To provide a safe heating vaporization system for a liquefied gas storage tank having a simple structure of heating/vaporizing liquefied gas inside a tank accelerating vaporization by detecting a temperature or pressure of the tank in addition to natural vaporization, the system which can be installed simply. SOLUTION: An IH heater unit 5 has: an explosion prevention casing 10 attached in a cylinder wall 12 of the liquefied gas storage tank; a band 11 attaching the explosion prevention casing 10; and a coil temperature detection sensor 8 attached separately from the attachment locations of a coil 9 for induction heating, and the IH heater unit 5 detecting the temperature of the coil 9 for the induction heating. A tank pressure detection sensor 7 is attached in a liquid picking valve 23. An inverter control section 3 controls an inverter power source 2 depending on detection results of the tank temperature, tank pressure and coil 9 temperature by inputting detection outputs of the tank temperature detection sensor 6, the tank pressure detection sensor 7 and the coil temperature detection sensor 8.
