Beschreibung
Zusammenfassung:	A heating system (203) includes a heat pump unit (220) that carries out an operation with electric power, a flow circuit (203a), a boiler unit (210) that includes a burner (211) and heats water, and a heating control unit. The heat pump unit (220) includes a heat pump circuit (221) through which a refrigerant circulates. The water heated with the refrigerant flows through the flow circuit (203a). The heating control unit includes an upper limit value acquisition unit and an operation control unit. The upper limit value acquisition unit acquires an upper limit value of the power consumption by the heat pump unit (220). The operation control unit controls the operation of the heat pump unit (220) to maintain the power consumption at a value below the upper limit value in a first time zone during which the power consumption is restricted to a value below the upper limit value. The operation control unit also causes the boiler unit (210) to carry out the operation when an amount of heat applied to the water by the heat pump unit (220) is insufficient in the first time zone.
