This chemical heat-storage device 10 for heating an object to be heated is provided with: a reactor 11 provided with a heat-storage material 11a which generates heat as a result of a chemical reaction with a reaction medium, and desorbs the reaction medium as a result of absorbing heat; a reservoir 12 for storing the reaction medium; a connection pipe 13 which connects the reactor 11 and the reservoir 12, and allows the reaction medium to flow therethrough; an opening/closing valve 14 provided to the connection pipe 13; a control unit 15 for controlling the opening and closing of the opening/closing valve 14; and a temperature acquisition unit for acquiring the temperature of the reactor 11. During a heating mode in which the object to be heated is heated in the reactor 11, in cases when the temperature of the reactor 11 becomes equal to or greater than a temperature at which the reaction medium can be recovered, the control unit 15 shifts to a recovery mode in which the reaction medium is recovered. When implementing control in the recovery mode, the control unit 15 closes the opening/closing valve 14 in cases when the temperature of the reactor 11 becomes less than the temperature at which the reaction medium can be recovered, and opens the opening/closing valve 14 in cases when the temperature of the reactor 11 becomes equal to or greater than the temperature at which the reaction medium can be recovered. |
