[Problem] The objective of the present disclosure lies in providing a heating control device and a control program, a fluid heating unit, a heating cycle device, and a vehicle air conditioning device comprising same, which integrate a function for detecting a dry-heating state of a heating element and a function for detecting a low flow rate state of a heating medium, and can thereby suppress an increase in the number of components.[Solution] A heating control device 6 according to the present disclosure is mounted in a fluid heating unit 10 comprising a tank 15, heater 4, a temperature detection device 51 having a temperature-sensitive portion in a downstream portion of a flow path, and a transistor 5, and the heating control device stores a value of a threshold rate Vt set on the basis of a temperature increase rate V0 of a coolant in the downstream portion of the flow path when a volume of the coolant is a defined amount and a flow rate of the coolant is 0 L/min, calculates a temperature increase rate V on the basis of a temperature detected by the temperature detection device, and turns the transistor off to stop application of electrical power to the heater when a value of the temperature increase rate is equal to or greater than the value of the threshold rate.
