Zusammenfassung:	A heat pump includes a control device configured to control conduction and shutting-off of electric power to a first compressor heater, and to control whether or not an alarm unit notifies an alarm. The control device causes the alarm unit to notify the alarm when the control device determines that duration of electric conduction to the first compressor heater is a predetermined period or longer. With this, it is possible to provide a heat pump that can control electric conduction to the heater to enable saving of electricity, and that can detect a problem in the controlling of the electric conduction to the heater.
