    Stop fireplace drafts

    If you have a fireplace in a well-insulated home, but leave the damper open, you could be increasing your energy use and costs by 30%. Winter air leakage through fireplaces can increase winter energy bills by $500 or more! Chimneys draw rising warm air out of your home which is replaced by cold air. Close your dampers or install a low-cost inflatable pillow in your chimney; it can be removed before fireplace use, and reinstalled after. Visit or search for “inflatable dampers” with your internet browser to learn about options.

    Watch this video to learn how to install a chimney balloon.
