PURPOSE: A flow-sensing type heating control system is provided to maintain desirable heating temperature by independently maintaining an uniform flow rate to the change of the flow rate supplied to different rooms. CONSTITUTION: A flow-sensing type heating control system comprises a hot water distributor, a flow control valve(30), a valve actuator(50), an impeller(20), and a flow sensor(22). The hot water distributor distributes warm water to each room through a plurality of individual valves. The flow control valve is mounted to a recovery pipe of an outlet side, and operated by a motor. The valve actuator controls the motor(40) of the flow control valve according to an input value of the flow sensor. The impeller is built in the flow control valve, and rotated according to the flow of the warm water. The flow sensor is installed outside the flow control valve correspondently to the impeller. The valve actuator comprises a flow detection unit and a unit for capering and determining the flow rate. The flow detection unit detects the input value of the flow sensor, and the unit for capering and determining the flow rate compares an existing flow rate with a real-time flow rate.
