Disclosed is a gas boiler which has a simple structure, which is easy to be installed, and which is manufactured at a low cost. The typical water tank is partitioned into an upper casing and a lower casing which are capable of communicated with each other. A circulation pump and a three-way valve are mounted to the lower casing in a row in the vertical direction, and a plurality of pipelines are arranged by using the above perpendicular arrangement as a reference. The circulation pump is coupled to the lower casing and the three-way valve is coupled to the circulation pump. Therefore, the size of the gas boiler is minimized and the manufacturing cost thereof is economized. |
