Frequently Asked Questions (FAQs)

1. Do Chimney Balloons really work?

How does it work? Chimneys act like giant hoovers, sucking air out of your home. This causes cold air to be pulled in from other gaps, causing the cold draughts we notice. The Chimney Balloon effectively blocks the chimney, stopping warm air from escaping and stopping cold air from getting in.

2. What is Chimney Balloon?

The Chimney Balloon is designed to inflate and push against all four walls of the chimney, holding itself firmly in place. There is a small vent in the side of the product which allows some airflow, permitting your chimney to “breathe”.

3. Can you reuse a Chimney Balloon?

A: Yes - You can reuse your Chimney Balloon. To uninstall the Chimney Balloon, simply open the valve on the end of the Chimney Balloon handgrip, wait for the balloon to deflate, then gently lower the balloon out of the flue area.

4. How do I choose a Chimney Balloon?

Selecting your Chimney Balloon For oblong and square chimneys, measure side to side and front to back. If there's a fire surround, measure the chimney beyond this. If you've got a headtorch, it's useful for keeping your hands free to measure. If you've got ski googles it will stop soot falling in your face.
