Product Description

You wouldn't put up with a hole in the wall or the ceiling yet this is exactly what you have with an open chimney. The Chimney Balloon saves on energy bills by preventing valuable heat from going straight up the chimney.

It is made to be quick to install yet allows removal for reuse again and again - designed for people who like to light a fire at the weekend. It's completely safe (if heated shrivels up) and also stops debris, soot and bird mess.

1. Remove the black rubber pump adaptor and attach the mouth inflation tube
2. Semi-inflate the balloon
3. Place the semi-inflated balloon in position in the flue or chimney
4. Fully inflate the balloon and close tap
Note: Inflate the balloon until it feels gently firm, like prodding your thigh, but not drum-taut. Blowing your hardest may cause the welded seals to fail. Test it by pushing the handgrip upwards - it should feel springy.

Size Matters
With so many chimney types, there is no simple rule for where the balloon is positioned. Look for the lowest (most accessible) place where there are two parallel walls for the balloon to grip when inflated (in the chimney gathering below the flue or higher up inside the flue/chimney proper). Then measure the width + depth and select a balloon to suit.

BRSIA Test Results
In 2013, BSRIA developed an analytical procedure to develop robust test data in measuring the energy savings of the Chimney Balloon ™ product. Engineers conducted a series of laboratory tests and wrote a detailed report.

Average reduction of airflow around 87% - from 40m3/h to 5m3/h.
Total energy and cost savings:
a. Scenario 1 (3-bed semi) - 4267kWh or £197 per annum
b. Scenario 2 (4-bed detached) - 6454kWh or £267 per annum

5.0 out of 5 stars Chimney balloon kit 6 May 2014
Verified Purchase
Does exactly what I needed it to do. It has stopped the rain and soot landing on the hearth. It also stops the peanuts that the birds drop down the chimney. Speedy delivery and a reasonable cost.

4.0 out of 5 stars Stops drafts 9 Feb 2013
Verified Purchase
I bought this as I have a fire place which I kept on getting cold drafts from. My fireplace is quite small - and I also have a lined chimney with a 6" liner - the fireplace has a closing plate but most recently i've noticed it's taken a long time to heat my room. So after a bit of searching around I decided to buy one of these balloons.

My Liner has a collector hood and I was able to just about push it up high enough to make a good fit - if anything this might be a little bit bigger than I needed.


You attach all the components, set the valve to open, position the balloon slightly inflated into the chimney. Then inflate the balloon by blowing into a tube.

1st complexity - the kit comes with a valve - its either open or closed, once inflated the moment you stop blowing and take the tube away from your mouth, air escapes (unless you quickly put your finger over the tube).(A one way valve with a release would have been better than the tap open/close type fitted.

2nd complexity - whilst holding your finger on the tube (so not to let any air out), you have to attempt to locate the valve (which is now in your chimney) and close it.

To remove the inflation tube you yank the blow up tube out of the valve and set aside for the next time you need to blow it up. I guess you could leave it there, but personally i'd prefer not to have a tube which makes contact with my mouth gathering soot.

The kit comes with a tiny label to say "There's a balloon in the chimney dont light a fire", its tiny and i didn't really know what I was supposed to do with it! It doesn't attach to anything, so its a bit odd!


Since installing the balloon, the draft has gone away.

5.0 out of 5 stars What it says on the tin 29 July 2014
By Eddie
Verified Purchase
Does exactly what it claims to do. Stuffed it up my chimney and it stopped the flakes, moss, and other random bits from falling down. Hopefully will save a bit of heat in winter, too.

My chimney is apparently an XS, since this balloon was still a bit too large, but it wedged itself into place anyway. Can't complain!

2.0 out of 5 stars Bit of a let-down 8 April 2014
By dm99
Verified Purchase
The ballon is a good idea spoilt by its execution. A fully inflated balloon only lasts a day or two befoe it deflates itself to the point where you need to blow it up again. Maybe the problem lies with the valve arrangement which may not be airtight.

5.0 out of 5 stars Get one and save money. 16 Mar 2014
Verified Purchase
I bought two and they have been a boon. Draughts have been drastically reduced and the two rooms much warmer through the winter. The other thing was that before I fitted these, you could hear traffic and conversations in the street via the chimney! This has also been eliminated and now our two rooms are warmer and quieter. Delighted with the chimney balloons.
