<P>PROBLEM TO BE SOLVED: To provide a heat source machine that can implement water sealing of a drain discharge system by an inexpensively-providable structure employable even for a downsized heat source machine without restricting the shape and size of each member in the heat source machine. <P>SOLUTION: In this heat source machine 1 including a burner 15 for burning fuel, and a heat exchanger 18 for mainly recovering latent heat of combustion gas produced by operating the burner 15, a bath drop-in system 6 for dropping hot water into a bathtub, and a drain discharge system 20 for neutralizing drain produced in the heat exchanger 18 to be discharged to the outside are formed. A water sealing device 51 forming a part of the drain discharge system 20 and/or an upstream part of the water sealing device 51 are/is continuously connected to a water filling pipe 52 branched from the bath drop-in system 6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
