PROBLEM TO BE SOLVED: To provide a heating medium feeding system capable of reducing a thermal load supplied by a heat source machine with the number of starting and stopping times of a heat source machine decreased. SOLUTION: The heating medium feed system is constituted such that a control means executes heating medium feed control processing through which a feed state time in which a heating medium on-off means M, to which a working state is commanded, of a plurality of the heating medium on-off means M is maintained in a feed state is varied and regulated according to a thermal load and intermittently switched into a feed state, and heating medium feed control processing is executed to effect switching to an intermittent feed state, and in the heating medium feed control processing, allotment control processing through which each heating medium on-off means M is intermittently switched to a feed state is executed in a form that, in the heating medium feed control processing, when there is a plurality of the heating medium on-off means M to which a working state is commanded, allotment in a reference period is executed so that each heating medium on-off means M is brought into a feed state in synchronism with a reference period, and a time zone in which each heating medium on-off means M is brought into a feed state is postponed with the elapse of time. |
