For the coziest setting, only this toasty duraflame® Electric Log Set Heater will do. Place it in your fireplace and watch the flames dance all night long. No vents to install, no gas lines to run, and no construction needed! All you need is an existing fireplace and an outlet. The logs project a lifelike flame effect onto the back of your fireplace, giving you the look of a traditional fire (but without the messy clean-up). Not only does this log set enhance your space, it delivers toasty heat that warms any area up to 400 square feet, which can help reduce those costly energy bills. Simply use this heater in the rooms you use the most. Rather than heating your entire home and vacant rooms, lower your thermostat and use this supplemental heater to save up to 15% during the winter months.
