PROBLEM TO BE SOLVED: To provide a simple device composition with easy maintenance, and to prevent the excessive rising of a temperature of a liquid staying in a heat exchange means even without providing a temperature detecting means in the heat exchange means. SOLUTION: The heat source device 1 can execute operation by a bathtub single mode singularly executing reheating of a bathtub 35. When the heat source device 1 is operated in the bathtub single mode, a control means 60 sets a temperature of hot water supplied to the bathtub 35 at a target temperature Tg from a value derived by substituting a preset reference target temperature Ts and a correction factorα, and a maximum combustion number Nm and an output number Nq of a burner 10 during operation in the bathtub single mode in a relational expression of Ts+α×(Nm-Nq).
