A Chimney Sheep – The perfect answer for a draughty chimney!

It is estimated that around £50 of warm air is lost up the chimney each year – for households with more than one open chimney in their property, this number can be significantly higher.

While you may not notice any cold draughts coming down on a mild day, during the winter months two things are happening which impact your energy bills. Not only does the the warm air produced by your central heating system rise up and out of the chimney; cold air travels unimpeded down it, producing really cold draughts that quickly cool down a room.

The chimney sheep is a 100% sheep wool product designed to keep warm air in your house and cool draughts out! It is just about the only truly sustainable chimney draught-proofing solution out there.

Why not block a chimney using newspaper?

Sure, blocking a chimney with newspaper is definitely cheap, but there are two issues with doing so. The first is that it creates a real risk of chimney fires if the paper is forgotten and the fire is lit. The second is that if rain comes down the chimney, it makes the paper wet and normally the paper just falls out as a big messy mulch.

The best chimney draught excluder

The Chimney Sheep is something we rate pretty highly. Firstly because sheep wool doesn’t burn, it self-extinguishes due to the moisture held within the wool fibres. Secondly, the Chimney Sheep is mess-free and can be removed easily if you want to use the fire at any point. We offer all sorts of different shapes and sizes so that you can find a sheep to fit your exact chimney, ensuring a snug, draught-free fit!

You can insulate your loft, floor and walls as much as you like but your home will never be completely efficient until the chimneys are blocked. The natural and sustainable Chimney Sheep allows you to temporarily block cold draughts – perfect if the fire is still used from time to time.

    Easy to place and remove, easy to clean I just vacuumed it and it insulates well. I recommend it for all who have a chimney they don’t frequently use.

    Works well! Why not 5 stars? I think the chimney ballon’s applicator rod isn’t long enough. It needs a extra bit in the middle to push it up if the chimney gets thinner a bit higher up like our one. Apart from that, once it is up there it is a nice snug fit, and you can’t feel the cold air coming down anymore, so I guess the best chinney draught proofer (not sure that is the correct word!) we have come across.

    Excellent prompt delivery and works very well (although hidden from view). Previously we have used a chimney balloon, but it keeps going flat and then falling down into the chimney place, so we decided to try this. `Would really recommend to anyone with a draughty chimney!

    I have a rather large chimney so buying the chimney sheep to fit was rather expensive. However, it arrived and installing it was pretty easy. Seems to have made a big difference. The problem with chimneys is that hot air escapes up them, which causes cold air to be sucked into the room from other areas, like the door.

    Purchased the wrong size and had to pay postage to return it. Works ok but basic product, quite messy if your chimney is dirty.

    Brilliant! Thank you all! Works well after I picked the correct size using your table. Our living room is a lot warmer now.

    Have a cold draughty chimeny in TV room so needed to get something to block it, so it was a straught choice between this and a chimney balloon. The chimney sheep in my mind had obvious advantanges, the main one being that it would not require re-inflating over time. It fits really snuggly in the chimney and the draughts have stopped so works well.

    Fully prepared for winter. Bought a Victorian end-terrace last year and went through a cold and draughty winter. Freezing house with howling winds coming down the chimney. Looked everywhere for a sustainable product and found the Chimney Sheep on the EcoStore. Good service and also the cheapest I have seen online!

    Does the job nicely. Had to make a little incision on the side to snug it in but working well. Handle positioned so i can remove if i want to. Thanks for a prompt service.

    Bought one for a chimney that is used about twice a year. Blocks the draughts and stays up there so can’t ask for anything more. Prompt delivery and great customer service when ordering as well.

    We got one of these for the chimney in the lounge. We oversized it and then cut it to ensure a snug fit. Seems to have worked well although I do worry when I take it out, it will act as a chimney brush and pull stuff down the chimney!
