The present invention relates to a high efficiency boiler (1). The high efficiency boiler (1) including a plurality of section parts (100) which is connected in a line and has a lower connector (110) formed at a lower portion of the section part (100) and an upper connector (120) formed at an upper portion of the section part (100), comprises: a combustion chamber (130) which has a through hole formed at the central portion of the section part (100) in such a way that combustion gas burnt by a burner moves; a first path (140) which is formed on the outer circumference of the combustion chamber (130) and has at least one first gas passage (141), such that the combustion gas passing through the combustion chamber (130) moves in reverse; second paths (150) which are formed at upper and lower parts of the first path (140) and each of which has a second gas passage (151), such that the combustion gas passing through the first gas passage (141) moves in reverse again; a first main pipe (160) which is formed inside the section part (100) and is formed in a ring shape between the combustion chamber (130) and the first path (140); a second main pipe (170) which is formed between the first path (140) and the second path (150); a third main pipe (180) which is formed inside the border of the section part (100) and connected with the second main pipe (170); and a connection water passage (190) which is communicated with the first main pipe (160) and the second main pipe (170) in such a way that supplied water is circulated through the lower connector (110). |
