PURPOSE:To enlarge the sectional area of heat transfer, to control the passage of combustion flames and to increase the heat transfer efficiency of the titled bath heater by a method wherein a plurality of annular heating members for supplying bath hot water and plurality of annular heating members for supplying hot water for other purposes are connected close to one another to thereby form a vertical boiler body. CONSTITUTION:The annular heating members 3 for supplying bath hot water and the annular heating members 3' for supplying hot water for other purposes are connected together to thereby form a centrak hollow cylindrical chamber 4. In this case, rows 1 and 1' of the annular heating members 3 and 3' are brought into contact with one another by laying the memebers 3 and 3' one above another so that an integral heating cylinder 6 is formed with a series of flame passages 5 provided in the gaps among the members 3 and 3'. Further, one side ppening 7 of each of the annular heating members 3 (for the bath hot water) is made to communicate with a bath hot water supply header pipe 11 through an upper circulation pipe 9 while the other side opening 12 thereof is made to communicate with a circulation header pipe 15 through a lower circulation pipe 13 to thereby make the hot water in a bathtub to convect naturally. On the other hand, the plurality of rows 1' of the hot water supplying annular heating members 3' are made to communicate with one another through U-shaped connecting pipes 16 and one side opening 17 of the annular heating memeber 3' of the lowermost row 1' is made to communicate with a cold water supply port while one side opening 20 of the annular heating member 3' of the uppermost row is made to communicate with a hot water supply port.
