A Chimney Sheep is a removable chimney draught excluder made from highly durable, naturally breathable Herdwick wool. The wool is felted to create a perfect plug for the chimney and a handle added for easy insertion and removal. A Chimney Sheep makes your home feel more comfortable by stopping warm air escaping and preventing cold air coming in as well as reducing wind noise, energy bills, CO2 emissions and any debris that may fall down your chimney. Chimney Sheep Features A perfect fit When inserted into an open chimney flue, the woollen pad of a Chimney Sheep compresses to fit perfectly in flues of all shapes and sizes. Natural ventilation Other chimney draught excluders require a small gap to be left in your flue to allow ventilation. Wool is breathable so no gap is needed, making a Chimney Sheep much more efficient. Once inserted into your chimney flue the 4.43 tog rated Chimney Sheep acts like a duvet, blocking 95% airflow into and out of your chimney, naturally permitting sufficient ventilation to ensure no damp issues occur. Keeps warm air in By blocking the majority of the air flow, it prevents the stack effect occurring. A Chimney Sheep stops warm air escaping through an open chimney and prevents cold air being pulled in via other gaps, helping a property retain its heat and feel more comfortable. Without a Chimney Sheep An open chimney is likely to be the single biggest source of air loss in a home. It is comparable to leaving a window open all the time, except that the passage of warm air out is exacerbated by a phenomenon known as the stack effect. Open chimneys will draw an average of 80 cubic metres of air out of a building per hour, more often that not it is warm air produced from our heating systems! The volume of air that escapes needs to be replaced, so cold air is pulled in from other leaky parts of the building, such as keyholes, gaps around your doors and tiny gaps around your windows With a Chimney Sheep A Chimney Sheep will reduce the amount of warm air being pulled out of your home, whilst still providing sufficient ventilation. Your house retains its heat! Less hot air is leaving, so less cold air is pulled in! The result? A warmer, comfier, more energy-efficient home! Benefits of a Chimney Sheep Makes your home feel more comfortable By stopping your warm, heated air escaping and cold air getting in, a Chimney Sheep helps to keep your home at a pleasant temperature. No more wind noise Say goodbye to those horrendous howling winds coming through your chimney by plugging it with a Chimney Sheep (you can turn your TV volume back down now…). Reduces your energy bills A Chimney Sheep stops about 5% of your household heat from escaping, reducing your heating bill by about 60 GBP per year on average. Cost effective energy savings A Chimney Sheep is one of the most cost-effective ways to draught proof a home, paying for the cost of itself in 3 – 6 months. To compare, double glazing windows takes about 50-60 years to pay back on average. Reduces your carbon footprint A Chimney Sheep makes your heating more efficient, reducing your CO2 output by up to 250kg per year. Stops wildlife and debris falling in No more surprises in the hearth, a Chimney Sheep will catch it all and stop your curious cat getting stuck up the chimney too! Long lasting To make sure a Chimney Sheep lasts, the wool is treated with a unique ionic protect plasma which makes it 100% moth proof. Tests have shown that it should last 10 years or more. Easy to remove and insert If you have a fireplace that you use regularly, you can still have a Chimney Sheep as it is super simple to remove and insert as needed, using the handle attached. Before you have a fire, take it out and once your fire has finished and the chimney is cold, you can put it back in. How to measure for your Chimney Sheep Step 1: Take a look at your chimney flue Use a head torch or prop up a regular torch to look up your flue. Ensure you have a tape measure to hand. Depending on the shape of your flue, depends on how you measure but don’t panic, we’ll talk you through it. Step 2: Locate the nearest, narrowest opening of your chimney flue Regardless of the shape of your chimney flue, your Chimney Sheep always needs to go in the nearest and narrowest opening to you, even with a fire surround. This is where you'll need to measure. Your Sheep will come with a 15cm handle and 15cm extension rod giving 30cm of reach altogether. It’s important to make sure the safety dangle is visible so buy more extension rods if you’re pushing it more than 30cm up the chimney. Step 3: Measure your flue Round flue: measure the diameter. You want a round Sheep that is an inch or so larger than the flue so it wedges in nicely. Square or oblong flue: measure the depth and width. You want a Sheep with depth and width measurements that are a couple of inches larger than your measurements so it wedges in nicely. ‘Odd-shaped’ flue (D-shaped, trapezium etc): measure the largest depth and width measurements of the opening (the longest and widest bits of the shape). You want a Sheep with depth and width measurements that are a couple of inches larger than your measurements so it fits snugly. The felt will squash the narrower parts of the flue to fit and create a seal. Step 4: Choose your Chimney Sheep! Referring to the size chart in the listing images above, you'll be able to work out the size of Chimney Sheep you need.

My 7.5 inch chimney draught excluder is a bit loose in our 7 inch flue but still works. **Q: My chimney is 10" ×12" what size chimney sheep should I order?** A: Hello, We'd recommend our 13" x 13" Chimney Sheep - so it's a little bigger in each direction than the chimney so it holds itself in place! Kind Regards, Taylor **Q: Will this work/ fit a 5 1/2 inch old gas fire flue? Gas fire has been taken out obviously** A: The 8" Round should work for that as it will simply squash into place. Kind regards Susan Chimney Sheep Ltd **Q: I’m considering using a bio ethanol fire insert for my log burner. Do I need to remove the sheep and can I keep the door closed when lit?** A: Hello, In this situation I would advise removing the sheep - simply because bioethanol log burner inserts are generally not flueless!
