A laundry treating apparatus may include a drum that receives laundry item therein, a heat pump that circulates a heating medium, a compressor that compresses the heating medium, a condenser that heats air to be transmitted to the drum, an expander that expands the heating medium, and an evaporator that cools air transmitted from the drum. A heater may re-heat air heated by the heat pump, and a sensing device may sense a state, such as temperature, of the heating medium. A controller may calculate energy efficiency based on the sensed state of the heating medium. Energy related information including the calculated energy efficiency may be displayed on a display so that energy efficiency may be monitored real time. |
