<P>PROBLEM TO BE SOLVED: To appropriately distribute capacity when simultaneously using hot water supply and a bath in a combustion device having a one-can and three-water function. <P>SOLUTION: This combustion device comprises a heat exchanger device 16 through which a hot water supply circuit 15 heated by a burner passes; a water supply part 17 and a hot water discharge part 18; a hot water supply pump 27; a hot water supply heating indirect heat exchanger 24 and a hot water supply bath indirect heat exchanger 26 in which the hot water supply circuit 15, a heating circuit 23 and a bath circuit 25 exchange heat; a heating pump 28 and a bath pump 36 circulating water in the heating circuit 23 and the bath circuit 25; and a control means 37 for controlling the circulating quantity of the bath pump 36 when simultaneously operating hot water supply and the bath. In the case of starting the operation of the bath circuit 25 during hot water supply operation, hot water supply operating performance is secured by controlling the circulating flow of the bath circuit 25. <P>COPYRIGHT: (C)2007,JPO&INPIT |
