The heating ring cylinders of large and small diameters are wound together to form heating rings of large and small diameters, and the heating rings of large and small diameters are appropriately passed through flame heating and polymerized in a vertical direction, and installed on a combustion furnace. The upper end opening of the metal pipe for heating is connected to the upper communication pipe which is connected to the upper heating circulation pipe connected to the inside of the upper part of the bathtub, and the lower end opening of the metal pipe for heating the bathtub water is

A heat conductive metal of a heating ring in a one-can, two-channel type bath boiling and hot water supply device in which a flame heating path and the upper opening of the large and small diameter heating ring are connected to the inside of the large diameter heating ring through a communication path. In addition to increasing the heat absorption effect of the pipe, it can be used not only when there is water in the spirally wound heat conductive metal pipe of the heating ring of both systems, but also when there is no water inside the spirally wound heat conductive metal pipe of the heating ring of one system. Also, the heat transfer effect of the heat exchange part is aimed at efficiently transmitting the heat absorbed by the spirally wound heat conductive metal pipe of one system of the heating ring to the pipe wall of the spirally wound heat conductive metal pipe of the other system. Regarding the improvement of the one-can, two-channel type bath boiling and hot water supply device that increases the temperature, the metal pipe for heating the bathtub water and the metal pipe for heating the hot water are soldered together with a heat conductive solder such as a copper alloy or an aluminum alloy. In addition, perpendicular heat-absorbing metal heat-absorbing fins are integrally welded to the inner surface of each screw-wound bathtub water heating and hot water supply heating metal pipe of the large and small diameter heating ring cylinder, and its implementation In one aspect, the lower opening of the smoke tube and the inner opening of the inner small-diameter flame heating path are appropriately shut off from the inside of the combustion furnace by a sealing plate,

In order to be able to be machined and processed, two systems of heat-resistant, heat-conducting heating metal pipes such as copper pipes or aluminum pipes for heating bathtub water and heating hot water for showers etc. are spirally arranged in close contact with each other above and below. The heating ring cylinders of large and small diameters are wound together to form a heating ring cylinder of large and small diameters, and the heating ring cylinders of large and small diameters are passed through the flame heating path as appropriate, and the heating ring cylinders are tightly stacked and installed on a combustion furnace, and the bathtub of the single heating ring cylinder is formed.

A lower communication pipe connected to a lower heating circulation pipe connected to the inside of the lower part of the bathtub was connected through a circulation pump, and the upper end opening of the heating metal pipe for hot water was connected to a hot water supply discharge pipe of a shower or the like. A one-can, two-channel type bath boiling and hot water supply device was developed earlier, in which the lower end opening of the hot water heating metal pipe was connected to a communicating pipe that communicated with a water supply pipe that communicated with a water supply source such as water supply.

On the other hand, the invention of this application significantly enhances the heat transfer effect of the heat exchange part in this type of device. By spirally winding the pipes while remaining round and completely soldering the mutual pipes, the heat transfer effect is increased and the process of forming each pipe into a particularly rounded or octagonal shape is avoided, and furthermore, the process of forming each pipe into a rounded or octagonal shape is avoided, and it is also possible to A heat-absorbing fin with an extremely large heat transfer area, which is continuously bent using a plate or the like, is welded together with a heat-conductive solder to the contact surface of each heating ring, spanning both pipe systems. This means that heat transfer can be achieved extremely effectively by switching the purpose of use to either boiling a bath or supplying hot water, so it is possible to achieve extremely effective heat transfer. It is extremely useful as it provides a highly effective thermal effect.
