PROBLEM TO BE SOLVED: To provide a hot water circulating type heating system capable of supplying and circulating hot water at the standard flow for ensuring an optimum radiation quantity to each terminal radiator. SOLUTION: This hot water circulating type heating system is provided with a heat source machine 2 for producing hot water; a plurality of terminal radiators 4, 6, 8, 10 to which hot water from the heat source machine 2 is circulated; flow regulating valves 50 provided corresponding to the plurality of terminal radiators 4, 6, 8, 10; and a controller 52 for controlling the heat source machine 2. The controller 52 is provided with an opening computing means 54 for computing the opening of the flow regulating valves 50. The opening computing means 54 computes the opening of the flow regulating valves 50 based on information on the standard flow and pressure loss of the plurality of terminal radiators 4, 6, 8, 10. The opening of the flow regulating valves 50 is computed based on information on the pressure loss of hot water piping for feeding and circulating hot water, in addition to the information on the standard flow and pressure loss.
