The purpose of the present invention is not only to use a heat exchanger to heat water in a hot water storage container to store hot water, but also to heat the fluid flowing through a heating pipe with a heat exchanger that heats water in a hot water storage container. In addition, when heat is exchanged with the fluid flowing through the heating pipes, the temperature inside the hot water storage container is high, so the heat does not escape, and the fluid inside the heating pipes can be heated, resulting in effective heating. We provide water heaters that can store hot water.

から排出される。 When the burner 7 of the heat exchanger 4 burns, hot air flows through the buffle plate 6 of the horizontal cylinder 5 of the heat exchanger 4 and is exhausted from the exhaust pipe 8. At this time, the exhaust fan 9 is driven, and the hot air is forced to flow into the horizontal cylindrical body 5 of the heat exchanger 4, and forced combustion is performed. When the heat exchanger 4 is heated, the hot water storage container 1
The water in the upper part of the hot water storage container 1 quickly becomes hot water by exchanging heat with the water inside. At this time, the burner 7 is controlled by a thermostat to maintain the hot water in the upper part of the hot water storage container 1 at a constant temperature. The heated hot water is supplied from the hot water supply port 3 through the hot water supply pipe 21 as shown by arrow B, and the supplied amount of hot water is poured from the water inlet 2. Usually, only a small amount of hot water is used in the bathroom or kitchen, so even if only the hot water at the top is hot, it can be used sufficiently. By the way, when using a large amount of hot water such as when using a bath, the internal circulation pump 16 is driven to pump hot water from the upper part of the hot water storage container 1 through the bypass pipe 15 from the upper suction port 17 as shown by arrow C. By discharging hot water from the middle discharge port 19 to the bottom discharge port 18, hot water is circulated and the middle and lower portions of the hot water storage container 1 are also heated to a high temperature. At this time, depending on the amount of hot water to be used, switch the switching valve 20 to discharge hot water from the middle outlet 19 or the lower outlet 18, and select whether to raise the temperature to the middle of the hot water storage container 1 or to raise the temperature to the entire hot water storage container 1. do. On the other hand, when the heating circulation pump 12 is driven, water circulates through the heating pipe 11, and heat is sent to the heating device to perform heating. That is, the burner 7 burns and the heat from the heat exchanger 4 is received by the heating heat exchange section 10 to perform heating. At this time, since the hot water in the upper part of the hot water storage container 1 is high temperature, heat radiation is small and heat can be exchanged efficiently. Heat can be given to the heating heat exchange section 10 from the air. Further, when the pressure of hot water in the hot water storage container 1 becomes high, the hot water flows out through the safety valve 24 and accumulates in the replenishment tank 26 from the communication pipe 25 as shown by arrow D. The water in the water replenishment tank 26 is replenished into the heating pipe 11. Excess water in the water replenishment tank 26 is transferred to the overflow pipe 27.
is discharged from.

上がりも早くなるという利点がある。 Since the present invention has a heat exchanger for heating running through the hot water storage container, the water in the hot water storage container can be heated and stored by the heat exchanger, and an outer cylinder can be fitted around the outer periphery of the heat exchanger. Since the space between the outer surface of the heat exchanger and the inner surface of the outer cylinder is used as the heating heat exchange section of the heating pipe, the heat from the heat exchange section is transferred to the heating pipe through the heating heat exchange section. It can receive heat and heat the room, and since a heat exchanger and heating heat exchange section are installed at the top of the hot water storage container, heat does not escape from the high temperature hot water at the top of the hot water storage container, and when heating, heat is not lost. The heat from the exchanger is directly used for heating, allowing for efficient heating.In addition, when heating starts and the temperature of the heat exchanger is low, the high temperature hot water at the top of the hot water storage container can assist in heating, making it easier for the heating to start. It has the advantage of being faster.
