According to the above feature of the present invention, when hot water having a temperature higher than the set hot water supply temperature from the solar water heater or the like is supplied to the water inlet pipe, the flow rate increases from the start of supply and the minimum working water amount of the water mixture controller is increased. At first, only the water mixture controller starts to operate, and the controller mixes the hot water from the hot water outlet pipe and the water from the bypass pipe (actually hot water above the set hot water supply temperature) to reach the set hot water temperature. Try to work. In this case, since the hot water after mixing naturally becomes the set hot water supply temperature or higher, the water mixture controller operates more and more in the direction of increasing the water on the bypass pipe side to maximize the water mixture ratio on the bypass pipe side.
For this reason, the hot water supplied to the water inlet pipe almost flows into the bypass pipe, the flow rate to the instantaneous heating can body side is hardly increased, and the state is kept below the minimum operating water amount of the instantaneous heating can body. Therefore, the instantaneous heating can body is held without starting the operation. That is, hot water having a temperature higher than the set hot water supply temperature from the solar water heater or the like is supplied as it is without being heated. Most of the hot water is supplied through the bypass pipe, and the amount of hot water that passes through the instant heating can body is very small. be able to.

As a normal case, the control operation by the controller 80 when water is supplied from the water inlet pipe 20 is shown in FIG.
Describing with reference to the curved line indicated by the dotted line in FIG.
When the can body flow rate sensor 21 detects the minimum operation start water amount M ON of the water mixture controller 50 or more by starting the supply of water to the
The controller 80 starts the operation of the water mixture controller 50. As a result, the water mixture controller 50 opens the bypass pipe 40 side from the closed state. However, since the temperature by the hot water supply temperature sensor 61 after mixed water is lower than the set hot water supply temperature, the mixed water ratio on the bypass pipe 40 side does not increase, and therefore the flow rate flowing to the instantaneous heating can body 10 side gradually increases, The flow rate detected by the can body flow rate sensor 21 eventually reaches the minimum operation start water amount B ON of the oil burner 11, the operation of the oil burner 11 is started, and combustion is started. As a result, hot water discharge to the hot water discharge pipe 30 is started, and the temperature is adjusted to a predetermined set hot water supply temperature. The controller 80 calculates the required amount of heat from the set hot water supply temperature, the incoming water temperature, and the total incoming water flow rate, adjusts the combustion input of the oil burner 11, and mixes it with the hot water actually discharged to the hot water discharge pipe 30. This is performed by finely adjusting the temperature of the hot water supply temperature sensor 61 to the set hot water supply temperature by adjusting and mixing the water from the bypass pipe 40 by the water regulator 50. On the other hand, when the hot water supply runner (not shown) of the hot water supply pipe 60 is closed, the incoming water flow rate decreases and stops. Therefore, the flow rate detected by the can body flow rate sensor 21 is the minimum operation stoppage water amount B OFF of the oil burner 11. , The operation of the oil burner 11 is stopped, and then the flow rate detected by the can body flow rate sensor 21 becomes the minimum operation stop water amount M OFF of the mixed water controller 50, and the operation of the mixed water controller 50 is stopped,
The bypass pipe 40 is in the fully closed state which is the initial state.

Next, the control operation by the controller 80 when the hot water having a temperature higher than the set hot water supply temperature is supplied from the solar water heater 70 to the water inlet pipe 20 will be described with reference to the solid curve in FIG.
Now, when the supply from the solar water heater 70 is started, the flow rate flowing to the can body flow rate sensor 21 increases, and the water mixture controller 50
When the minimum starting water volume M ON of the
Only the controller starts the operation, opens the bypass pipe 40 from the fully closed state, and sets the hot water from the hot water outlet pipe 30 and the water from the bypass pipe 40 (actually, hot water above the set hot water supply temperature). It works to reach the hot water temperature.
And in this case, the hot water after mixing is naturally higher than the set hot water supply temperature, so that the water mixing controller 50 operates more and more in the direction of increasing the water on the bypass pipe 40 side to maximize the water mixing ratio on the bypass pipe 40 side. To do. Therefore, most of the warm water supplied to the water inlet pipe 20 flows into the bypass pipe 40 side, the flow rate to the instantaneous heating can body 10 side hardly increases, and the minimum operation starting water amount B of the instantaneous heating can body 10 is B. Settles down to a constant flow rate below ON . Therefore, the instantaneous heating can body 10 is held without starting operation from the beginning, hot water having a temperature higher than the set hot water supply temperature from the solar water heater 70 is not heated, and most of them are smoothly and through the bypass pipe 40. Hot water is supplied as it is with little heat dissipation.
