ABSTRACT:
A liquid heating apparatus according to the present invention comprises a cylindrical outer shell, an inner shell consisting of a cylindrical body whose upper and lower portions are respectively provided with an enlarged flue chamber having a cross-sectional area remarkably larger than that of said cylindrical body, said inner shell being disposed within said outer shell so as to provide a space forming a water jacket between the two shells, a fire chamber formed by closing said cylindrical body at above said lower enlarged flue chamber, an insert hole for burner which penetrates said inner and outer shells and opens into said fire chamber, a rising heated gas chamber which is disposed above said fire chamber so as to communicate with it as well as said upper enlarged flue chamber, a falling heated gas space formed by intercommunicating said upper and lower enlarged flue chambers by means of plural smoke pipes penetrating the water jacket formed in between said outer shell and inner shell, and a flue outlet provided for said lower enlarged flue chamber.
