An apparatus for producing fresh water from sea water in which a vertical accumulator utilizes the sensible heat of sea water so as to evaporate said sea water to a temperature above 100 DEG C. under pressure, a heat-exchanger connecting between the upper and lower portions of said accumulator causes a high temperature liquid to effect heat-exchange with sea water to be evaporated, a fresh sea water feed line connected to the lower portion of said accumulator adjusts the pressure within the accumulator and an evaporator receives higher temperature sea water. The accumulator accumulates heat in such a manner that the upper portion of said accumulator holds higher temperature sea water and the lower portion of the accumulator holds lower temperature sea water so that when heat is accumulated, the amount of said higher temperature sea water increases and when heat is radiated, the amount of higher temperature decreases whereby sea water evaporates at all times.
