PROBLEM TO BE SOLVED: To provide a heating medium supply device capable of automatically closing a feed water cutoff valve of becoming an opening state, when the feed water cutoff valve becomes the opening state by a water hammer phenomenon. SOLUTION: A valve operation control means 41 is arranged for performing water replenishing processing, by opening the feed water cutoff valve 31 corresponding to a heating medium storage tank T when a heating medium quantity in the heating medium storage tank T becomes a preset lower limit value, and by closing the feed water cutoff valve 31 when the meting medium quantity in the heating medium storage tank T becomes a preset upper limit quantity or more, based on detecting information of a heating medium quantity detecting means S detecting the heating medium quantity in the atmospheric opening type heating medium storage tank T in a plurality of respective heating medium circulating passages R. The valve operation control means 41 is constituted so as to perform abnormality releasing opening-closing processing for closing a valve by opening the feed water cutoff valve 31 corresponding to the heating medium storage tank T increased in a storage quantity, when discriminating that a heating medium storage quantity of the heating medium storage tank T being not an object of its water replenishing processing, is increased more than before performing its water replenishing processing, after performing the water replenishing processing based on the detecting information of the heating medium quantity detecting means S.
