Gas water heater

Abstract

A gas water heater is disclosed. The gas water heater comprises a combustion chamber, a pipe assembly, a heat exchange device, and a plurality of heat conductors. The combustion chamber provides a gas flow. The heat exchange device is disposed above the combustion chamber. The heat conductors are disposed in parallel in the heat exchange device. Each heat conductor comprises a body, a plurality of trough holes, and a first flange. The body has an oblique side facing the gas flow. The through holes are disposed on the body. The first flange is formed along the oblique side of the body for collecting condensed water.
