The steam that has reached the fluid chamber comes into contact with the container to be heated through the gas-liquid separation functional polymer membrane, and the gas-liquid separation functional polymer membrane acts as resistance to the passage of the vapor, suppressing the amount of heat supplied to an appropriate level, and separating the gas and liquid. The vessel to be heated is heated together with the steam flowing in through the through hole provided at the lower end of the separation functional polymer membrane. The condensate that has been condensed by heating the heated container drips downward through the gap between the gas-liquid separation functional polymer membrane and the heated container, and then drips downward through the penetration provided at the lower end of the gas-liquid separation functional polymer membrane. It reaches the fluid chamber through the hole and is removed from the system by a vacuum pump.
