PROBLEM TO BE SOLVED: To circulate and supply a heating medium at suitable circulation flow rate to a terminal. SOLUTION: The heat supply system is provided with a heat source machine CH circulating the heating medium by an electric circulating pump 4 through a circulation path 3 connected to a terminal unit TU, and a control means 5 controlling the operation. The control means 5 executes a circulating resistance measurement processing measuring driving load in the case of operating of the circulating pump as the circulating resistance of the circulation path 3, and controls the operation of the circulating pump 4 so as to have a heating medium circulation capacity according to the measuring circulating resistance measured with the circulating resistance measurement processing.
