The 8" diameter chimney sheep fits into my 7" chimney liner perfectly. For over twenty years my coal effect gas fire chimney / flue liner has been haemorrhaging household heat during the autumn and winter months. Having read positive reviews and manufactures claims I though it was time to give the 'sheep' a try. We have a digital thermometer in the lounge, accurate to 0.1 degree C. I can confirm that with the sheep installed the lounge is at least 0.7 degrees warmer, given the same conditions. I am looking forward to reduced gas bills over the coming years. One word of warning - if you do decide to light your fire, remember to remove your sheep. As a bonus the 8 inch diameter chimney sheep fits perfectly into the 8 inch confectionary tubs you find in most supermarkets. The supplied handle and tag provides fair warning for not trying to light your fire with your sheep stuck up the chimney!

I've seen sheep's wool used as insulation in eco build homes before, but its use as a chimney draught excluder was a new one on me. The idea seemed preferable to an inflatable plastic chimney pillow. This was so easy to install - just attach the handle (with or without an extension section) and push it up into the flue. The 8" round version was perfect for our circular 6" flue. Down draughts and heat loss via the chimney instantly reduced - indeed, no draught at all is noticeable with this in place.I'm not remotely convinced by the claim that these stop debris, wildlife and insects falling in - this might prevent them from landing in your room when they do first fall, but since the chimney sheep is fitted at the bottom of the flue it does nothing to stop things from falling down the chimney itself or coming out into the room when the chimney sheep is eventually removed. But I'd thought that through before buying. The only real disappointment I have with this was that it was wrapped in a plastic bag, and the handle is made from plastic - the use of plastic seeming like a less good choice in an eco product.

Excellent product

Great product

I had to stuff insulation up my chimney separately to get a good seal. Having done that, I’m not sure if this add much value.

I live in a 1950s box. You know the kind. They all used to have back boilers in the chimneys and over the years home owners have taken them out and installed combi boilers elsewhere in the house. This leaves the open fireplace which one could choose to brick up, to cover with an electric fire and surround, or to leave open as a 'feature' of some sort in the living room. The other legacy of the back boiler is that somewhere in the living room there will be a not-insignificantly sized gas vent in the wall, which undoubtedly pulls in a draft which would register on the Beaufort scale.Now - you can have draft excluders under every door, you can install a cowl on the external wall to prevent the gale blowing straight in, you can install a hit-and-miss vent on the internal wall, but mark my words - you will still get the chilliest draft blowing into your living room which maintains the temperature at a constant 3 degrees below the rest of the house and makes a blanket a necessity when watching the telly in the evenings.Finally. FINALLY. After 7 years I worked out that the draft being pulled into the room from the vent, was largely down to the fact that the electric fire I had chosen to install in the 'hole' that the back boiler had left had two vents underneath it. Behind the electric fire was the chimney cavity and up the chimney a little way was the corrugated metal chimney flue....which had not been blocked off. The cold outside air was subsequently being sucked from outside, through the wall vent, and up the chimney flue, taking all of the heat from the room with it. I could also hear rain loudly bouncing off the chimney cap, and pigeons sitting up there coo-ing to one another, all acoustically amplified down the flue and into the living room. I knew I had to cap the flue from the living room end, but how? I was concerned about causing damp, and I didn't want to restrict the air exchanges in the house. After a bit of research, I happened upon the Chimney Sheep, which was the answer to everything! Ridiculously simple design, it's essentially a woollen plug, which has enough give for you to twist and manipulate into the chimney vent, blocking the draft but allowing air to move through it (so no problems with air circulation or damp). It has a handle on it, so should you have an open fire grate you can simply remove it when you light a fire, and replace it afterwards. I seriously cannot express the difference it has made in my previously Siberian front room, which is now positively cosy. I can only imagine the effect it's having on my energy useage - and as a plus...I can't hear the pigeons in surround sound anymore!

Love my chimney sheep! Does the job. We have small chimney opening so bit fiddly to fit but worth the effort and noticeable difference in keeping the room warm in cold and windy conditions. Happy to recommend
