Yes, Duraflame infrared heaters are designed to be energy efficient. The electric company will charge you between $0.17 and $0.25 per hour that the heat is on, depending on their rate. If you want to use this heater effectively, use the unit's built-in digital thermostat. Once the room reaches the desired temperature, the heating element will cycle off and enter a cooldown stage before turning back on again when the room has cooled down.
