PURPOSE:To obtain the titled apparatus for making a large amount of deaerated water with good efficiency, by providing a heating means for performing the deaeration of air dissolved in water, a cooling means for cooling deaerated hot water and a deaerated water storage means for storing deaerated water. CONSTITUTION:Raw water, from which impurities were removed by a pure water making apparatus 8, is preheated through a pump 9 and a first cooler 6 to be flowed in a heating deaeration tank 1 where heated to temp. of 80 deg.C-below b.p. by a heater. Deaerated hot water is flowed in the first cooler 6 to be subjected to the heat exchange with raw water and further flowed in a deaerated water storage tank 13 through a second cooler 7. The deaerated water in the storage tank 13 is held to predetermined temp. (37 deg.C) and always held to a fully filled state.
