At this time, as the upper heating tube 114 is formed to be stacked in a plurality of layers to form a plurality of side walls, the amount of circulating water that is intensively heated in the upper heating tube 114 is stacked in one layer to form a single side wall. It is about twice as much as if formed.

As such, as the upper heating tube 114 is configured to be stacked in plural layers, the amount of circulating water discharged to the discharge pipe 310 is increased as compared with the single stacked structure, and as a result, the discharge pipe 310 It is possible to reduce the number of times the valve 320v of the lift check valve 320 provided in the), thereby reducing the frequency of operation noise generated by the valve 330v.

On the other hand, as the circulating water is discharged through the discharge pipe 310, a negative pressure is generated in the inside of the heating tube 110, and the non-return valve 220 of the supply pipe 210 is opened by the generated negative pressure. Together, the circulating water in the circulating water tank 600 may be introduced into the heating tube 110.

Next, as shown in Figures 5 and 6, the circulating water before being discharged to the discharge pipe 310 through the backflow prevention valve 320 in a state in which gas and liquid are separated by the gas-liquid separation tank 400. The circulating water discharged to the boiler tube 700, the circulating water discharged to the boiler tube 700 is heated while circulating along the boiler tube 700 to form a heat exchange, the finished circulating water is circulated water tank 600 Is returned.

On the other hand, as shown in Figure 12, even if the gas-liquid separation tank 400 is not provided between the upper heating tube 114 and the non-return valve 320 is of course included in the scope of the present invention.

That is, even if the gas-liquid separation tank 400 is not provided between the upper heating tube 114 and the non-return valve 320, it is formed in a predetermined cross section and length and arranged in a vertical direction so that the circulating water flows upward. The discharge pipe 310 itself connecting the upper heating tube 114 and the non-return valve 320 may provide a gas-liquid separation space capable of separating gas and liquid.

Therefore, even if the gas-liquid separation tank 400 is not provided between the upper heating tube 114 and the non-return valve 320 of the circulating water discharge part, the gas and the liquid in the circulating water can be discharged in a separated state.
