PROBLEM TO BE SOLVED: To achieve a heat exchange unit, a heat source machine, a hot water system, a connection management program or a connection management method which simplify determination of pipeline connection of a heat exchanger in which hot water is used for heating and drying, and which enhance reliability of the pipeline connection.SOLUTION: A heat exchange unit (6) performs heat exchange between a heating medium and other medium by being connected to a heat source machine (4, hot water heat source machine 24) and receiving the heating medium of a predetermined temperature from the heat source machine, and the heat exchange unit (6) includes: a temperature sensor (12) for detecting a heating medium temperature at least at one of an inlet side and an outlet side of the heat exchange unit; and determination means (8) which, when detection temperature before heat exchange is defined as a first reference temperature, or a temperature which is lower than the detection temperature by the predetermined temperature is defined as the first reference temperature, compares one of the first reference temperatures with the detection temperature after the heat exchange, and which determines the pipeline connection with the heat source machine.SELECTED DRAWING: Figure 1 |
