Warm air rises and cold air falls. This simple scientific fact means that when you have an unlit fireplace, not only will the warm air leave your home, but cold draughts will be coming in. With a Chimney Balloon you can help prevent those draughts. Simply place the balloon into the chimney and inflate using the mouth tube or with a foot pump.
Chimneys are cleverly designed to draw air up and out of the building. The amount of warm air is lost varies depending on the height of the chimney, the temperature inside and the temperature outside. Chimney balloons come with their own cord and is important that it is visible at the top of the fireplace so no-one forgets it is there and lights a fire.
