Summary:PROBLEM TO BE SOLVED: To save electric power consumed by a circulation pump and reduce occurrence of noise and vibration and the like, and prevent production of condensation following overload operation in a warm water central heating system. SOLUTION: A flow rate of a fluid passing through a heat exchanger 2 is regulated by controlling the number of revolutions of a circulation pump 4 in response to the operation number of heat dissipators. Such construction prevents the circulation pump 4 from being fully operated at all times, so that consumed electric power is correspondingly saved and production of noise and vibration are reduced. Further, condensation is prevented from happening upon overload operation by reducing a flow rate in response to a heating load.
