PROBLEM TO BE SOLVED: To provide a heat source machine capable of efficiently preventing freezing of liquid in a device without unnecessarily disturbing a user, and a freezing prevention control method that can be implemented with such a heat source machine.SOLUTION: A heat source machine 1 in which air blown from a blower 5 flows into a combustion system 3 in which a combustion operation is not executed in a situation in which at least one of combustion systems 3 does not execute the combustion operation and in which the other combustion systems 3 execute the combustion operation executes a freezing prevention operation for preventing freezing of liquid in a predetermined device. Furthermore, an operation content of the freezing prevention operation is changed on the basis of combustion operation execution situations of the combustion systems and a value detected by a temperature sensor. |
