Designed to be used
The chimney balloon is effective mainly because of one single principle, warm air rises and cold air sinks.With the chimney balloon we can stop both at once, keeping cold air from entering the room, and warm air from escaping up the chimney.
Chimneys act as a funnel and pump to take warm air away. This is a good thing when your fire is lit and the warm air is full of smoke.
However, chimneys work hard even when there is no fire. Have you ever wondered why cold air rushes in through the gaps in the floors, doors and windows? (maybe even down the chimney !) It can’t get in unless it is going out at the same speed.
You could block your fireplace with a board or bricks but then it looks ugly, and you can’t use your fire when you feel like it. You’ll also find that your chimney will get damp because the bricks aren’t breathing.
You could stuff newspapers up the chimney throat, but they won’t be efficient, will probably move – and are a potential fire risk.
You could stick a seal on the top of the chimney, but it will cost you lots and you can forget lighting pleasant fires. Even worse, you will still be heating a large volume of air in the chimney.
OK – so get an ordinary balloon, inflate it and stick it in the chimney…BANG! (whoops, sorry) even if it doesn’t burst at once, it will shrivel up within a day !
That’s why you need the specially engineered, guaranteed, patented Chimney Balloon.
It will stay in place for years – and stay inflated. It will provide ‘double glazing’ for your fireplace. You can deflate it (and re-inflate it) any time you want a fire.
Even if you forget it – and light a fire, it will just melt, harmlessly. Best of all, it’s cheap and readily available at the click of a button.
