CHIMSOC - Balloon for Chimney - (Medium Rectangle 60cm x 30cm (24" x 12"))

I bought this CHIMSOC Chimney Balloon to stop cold air from coming down my chimney, and I’m honestly amazed at how well it works! As soon as I put it in, I could feel the difference—no more draughts, and the room stays so much warmer.✔️ Super Easy to Install – Took me less than a minute! Just inflate it, pop it into place, and you’re done. The little tube makes it really simple.🔥 Keeps the Warmth In – I was skeptical at first, but it really does help retain heat. I’m hoping this means lower heating bills too!🧹 Stops Soot & Dust – No more bits of debris falling onto the hearth, which means less cleaning—always a win!💨 Still Lets the Chimney Breathe – It allows a small amount of airflow, so no worries about condensation or damp.💪 Strong & Reusable – The material feels durable, and I love that I can take it out and use it again when needed.Such a simple but effective solution! If you have a cold, unused chimney, I’d definitely recommend this—worth every penny! 😊

So at first it was good but eventually start sliding down and deflating. Is quite straightforward to apply but the tube isnt that long and if you don't have baloon pumping device you need to use your imagination 😉

TL;DR - the product really works, buy it!!!I bought 2 of these for the 2 chimneys in my apartment as it always seemed difficult to keep the place warm. Installation was as simple as shoving it up the flue and giving it a good hard blow in to the long soft tube.Seriously though, as soon as I put my heating on I could feel the difference. I could also hear the difference as I could always hear the wind/ draft coming from the chimneys, but after installing the balloon I can't hear or feel any draft and it's been pretty dang windy here! I immediately put my heating on and the entire apartment warmed up 2, maybe 3 times faster and it's seriously keeping the warmth for longer.Usually I'd get the place up to about 18°c before going to bed (I don't really like my place too warm as I've got plenty of personal insulation/ I'm fat as heck) and when waking up in the morning it'd have dropped to 10-11°c. Now, I'll wake up and even with outside having dropped below freezing and no heating on all night the thermostat is still reading at least 16°c.Last year was my 1st winter in this apartment and I was appalled at how much gas I was using just to keep it warm. Really wish I'd looked in to these sooner, but I'm looking forward to not paying out the backside this winter now I've installed these!200% recommend!

Had this for approximately one month now and I have re-inflated it 4 times already hence I am disappointed as it is not doing the job as intended. I have been very careful to make sure the "balloon" has no chance of a puncture and use a small electric pump to inflate it as I did not want to have moisture/expansion problems associated with breath - it has made no difference. I do not know whether the valve is at fault or the balloon itself. I thought this would be a neat/convenient solution but now I may have to cut some OSB to insert instead. Therefore, I cannot recommend, it has been a waste of money.

This is a good product. It fit perfectly in my chimney. Easy to use.

Bought 2 of these and they were easy to install and seem to do the job BUT one them doesn’t stay inflated, I have to re inflate every 2 weeks so I’m not convinced it’s going to help with draughtsEDIT contacted the seller who refunded me for the dodgy one so 5 stars for customer service

Helps fill the chimney hole so as wind and rain can’t get in. It’s okay. Does what it’s meant to do.

Very easy to use and good product just make sure you got correct pump
