The SmartBalloon is a reusable, simple and easy to use household device that reduces the amount of heat loss through the chimney flue while at the same time maintaining a ventilated living room when the fire is not in use. Because warm air naturally rises, the Chimney Flue is a major source of heat loss. The Chimney Flue Balloon effectively provides a barrier to prevent cold draughts and heat loss, saving you money on fuel bills and naturally making the living area warmer, more comfortable and with less cross draughts.
