Your fireplace adds beauty and warmth to your home but, it can be a source of heating and cooling (A/C) loss, making the chimney inefficient. A chimney damper is a great device to close off your chimney flue and help keep heat and cooling in your home and not up and out the chimney flue. A chimney damper is a fairly simple device used to close or partially close off the flue. They are usually constructed of metal and can withstand the heat of the fire and still function properly without damage. They are controlled by a handle, pull chain or latch. When the damper is in the open position it allows the smoke a way to exit the flue. In the closed position it helps prevent cold air from entering the house. This will help to make your home more energy efficient.
