- control device 150 may adjust the output of the pump 122 so that the rotational speed of the pump 122 becomes equal to the target value in each heating operation. By doing so, even when the heating apparatus 300 is divided into a plurality of systems and the number of systems used changes, the heating capacity to each system can be kept constant.
