Research has shown that an open damper, on an unused fireplace, can raise the overall heating energy consumption by 30%. This occurs since heated air rises and the fireplace chimney will draw air from the home. The net effect of an ineffective, missing or broken fireplace throat damper is similar to leaving a window open all winter long! The Top Damper seals in this heated air and provides ease of use when the fireplace is in operation.
