PROBLEM TO BE SOLVED: To provide a cogeneration system 40 and hot-water supply facilities, provided side by side for a heat source machine 10 as a different body, such that while heat efficiency of the heat source machine 10 is improved, the energy efficiency of the whole system is improved by effectively using hot water reserved in a hot water storage tank 90.SOLUTION: A cogeneration system includes a communication part 96 which communicates with a heat source machine 10, and a main-body control part 95 performs operation command control to determine whether the heat source machine 10 can be in hot water heating operation based upon main body outflow temperature as the temperature of hot water discharged from a main body-side outflow part 78a, and to output command information for limiting the hot water heating operation of the heat source machine 10 to the heat source machine 10 through the communication part 96 according to the determination on whether the hot water heating operation can be performed. |
