摘要： PROBLEM TO BE SOLVED: To enable heating inertia of a heater, the heating operation of which is stopped its, after the execution of a heating control has ended to be effectively utilized at heat consumption terminals. SOLUTION: A heating medium circulating type heater comprises a heating medium circulating means E for circulating a heating medium along a circulating passage 3 over a heater 33 for heating the medium and the heat consumption terminals 1, 2 and a heating control means C for controlling the circulating flow rate of the medium by the circulating means and the heating operation of the heater. In this heater, when a heating medium supply request is made to the terminal, the circulation flow rate or the heated amount of the heater is controlled, so that the heating temperature of the medium by the heater becomes a target temperature in response to the terminal. When request is eliminated, the heater control for stopping the heating operation of the heater is carried out. Thus, the control means carries out, after an execution of the heating control is finished, the heating control for recovering the heating inertia by controlling the flow rate, so that the temperature of the medium passing through the heater in an interruption of heating operation becomes the target temperature.
