PROBLEM TO BE SOLVED: To reduce energy consumption of an LP gas bulk feed system equipped with a forced vaporizing device. SOLUTION: The LP gas bulk feed system comprises a bulk reservoir 1 for storing LP gas, the forced vaporizing device 2 connected to the bulk reservoir 1 through a liquid phase line A, a feed line C connected to the forced vaporizing device 2 via a regulator 4 for liquid phase, a solenoid valve 8 disposed in the feed line C, a two-stage secondary regulator 5 disposed in the feed line C on the downstream side of the solenoid valve 8, a gas phase line B of which one end is connected to the bulk reservoir 1 via a two-stage primary regulator 3 for gas phase and the other end is connected between the solenoid valve 8 and the two-stage secondary regulator 5 of the feed line C, a temperature sensor 6 for detecting temperature of the bulk reservoir 1, and a temperature controller 7 for closing the solenoid valve 8 when the detected temperature becomes a lower limit temperature or lower or opening the solenoid valve 8 when the detected temperature becomes an upper limit temperature or higher.
