An open chimney is like leaving a window open. Fitting a Chimney Balloon blocks the flue preventing warm air from escaping and cold air getting in.
How to make a DIY chimney balloon Eco Thrifty Living
The Chimney Balloon is an inflatable fireplace blocker that prevents drafts from a chimney caused by a broken, warped, or missing flue damper. It stops heat loss by acting as a chimney plug draft stopper that air seals and insulates the fireplace. This saves you money and heat, and improves comfort. The Chimney Balloon usually installs above the damper, but also works in chimneys that have no damper.
