PROBLEM TO BE SOLVED: To provide a system capable of suppressing cost of facility as much as possible, facilitating maintenance and management, and transferring and filling liquefied gas (liquid) stably. SOLUTION: This liquefied gas transferring and filling system is provided with a storage tank device 1 incorporating a siphone tube as a liquid taking-out tube, liquefied gas heating devices 2, 3, and two machines of heat source corresponding to them. Operation of only the liquefied gas heating device on one side being in a fully filled condition among each heat source is controlled, each gaseous phase line connected with the storage tank device of both of liquefied gas heating devices 2, 3 and each liquid feeding line connected with a transferring and filling destination device are alternately opened, closed, and controlled, and a liquid receiving line connected with each liquefied gas heating device through a taking-out valve from the storage tank device in the interlocking relationship with the opening, closing, and controlling of each line so as to switch is provided. A part of liquefied gas liquid in a pressurized condition of the liquefied gas heating device on one side being in a fully filled condition is applied to the liquid receiving line. A venturi tube 7 for absorbing liquefied gas liquid at lower level than the taking-out valve from the siphone tube by negative pressure generated at this time and supplying it to the liquefied gas heating device on the other side is provided.
