うな欠点を有している。(Prior Art and Points of Interest) Conventionally, there are two main methods for configuring a large instantaneous water heater capable of producing a large amount of hot water. The first method is to configure a single heat exchanger itself in a large size as shown in FIG. 2(a), and configure 1iI2 burners in this large heat exchanger. However, with this method, a different heat exchanger is required for each required maximum hot water output amount, which increases the L1 cost, and the diameter of the water pipe passing through the heat exchanger also has to be increased, making it difficult to manufacture wooden lids. There are some disadvantages that come with it. Next, the second method is to install a heat exchanger for each burner, and connect and integrate the water pipes that pass through the i number of heat exchangers. Specifically, these water pipes are connected to the second The method of connecting in series as shown in Figure (b), and the method of connecting in series as shown in Figure (b),
In parallel as shown in figure (C)! ! There is a way to do this. However, although the former method has the advantage of making it easy to control the hot water temperature, the head loss becomes extremely large, making it difficult to secure a sufficient amount of hot water to match the increased combustion rate. It cannot be used in extremely low water pressure areas, and the hot water that has been heat exchanged in the fins of the heat exchanger on the upstream side of the flowing water path reaches the drum section of the heat exchanger on the downstream side. It has the disadvantage that the drum part of the heat exchanger on the side tends to warm up, and there are also problems from the viewpoint of durability.

という欠点を有する池、瞬間的温度変化への対応が遅い
というような欠点を有している。Unlike the former method, the latter method has the advantage that the head loss is not large and a sufficient amount of hot water can be ensured, but it does not require that each burner be burned in the same way at the same time and that the heat exchanger On the other hand, it is difficult to control the hot water temperature if the same amount of heat is not applied, and therefore each burner must always be burned at the same time, resulting in a large minimum amount of hot water. It has the disadvantage of being slow to respond.
