Claims

[Scope of utility model registration request]

hot water inlet pipe stub, hot water inlet header, multiple bent pipes, tube sheet,
In an exhaust gas heat recovery water heater consisting of a plurality of heat transfer tubes with enlarged heat transfer surfaces on the outer circumference of the tubes, a hot water outlet header, a hot water outlet nozzle stand, an exhaust gas inlet nozzle stand, an exhaust gas outlet nozzle stand, and a casing, on the outer circumference of the tubes, A plurality of heat transfer tubes each having an enlarged heat transfer surface were bent into a U-shape and inserted into a casing, and both ends of each heat transfer tube were fixed to a tube plate and passed through the tube plate to exit the casing. Both ends of each heat exchanger tube are attached to a hot water inlet header and a hot water outlet lug, respectively, which are placed with the longitudinal axis of the tube vertically or horizontally, through bent tubes, and the heat exchanger tube is inserted into the casing. An exhaust gas heat recovery water heater characterized in that the casing has a rectangular cross-sectional shape when cut at right angles to the longitudinal axis, and the exhaust gas flows outside the heat transfer tube along the longitudinal axis.
