Inventor: OSHIO TADAHIKO
IPC: F24H1/10
Filed: 1992-07-31
Abstract: PURPOSE:To control the number of operating units securing better hot water delivery characteristic by performing a controlling of the flow rate of water heaters starting operation most newly among those in operation to hold the quantity of passing water of a shell body of the water heaters starting operation previously above a specified value. CONSTITUTION:Hot water delivery paths 31, 32 and 32 on the outlet sides of heat exchangers 11, 12 and 13 are provided with water quantity adjusting valves 81, 82 and 83 each with overspillage preventing function and the hot water delivery paths 31, 32 and 33 on the downstream side with hot water delivery solenoid valves 91, 92 and 93. In the hot water delivery operation of a hot water heater 1 alone, the water quantity adjusting valve 81 with an overspillage preventing function accomplishes a prevention of the overspillage to make the amount of passing water of a shell body equal a set amount of the shell body. As the amount of hot water to be delivered further increases, the water quantity adjusting valve 82 with overspillage preventing function of the water heater 2 starting the operation of delivering hot water hold the amount of passing water of the shell body of the water heater 1 more than times as much as a set flow rate of the shell body. Thus, the water heaters other than those starting the operation of delivering hot water most newly always can secure the amount of passing water of the shell body exceeding a specified flow rate thereby enabling the prevention of the worsening of hot water delivering characteristic.
