  • Reduces your energy bills by up to £99 per year on average
  • Reduces your carbon output by about 250kg of CO2 per year
  • Stops wind noise coming down through the chimney
  • Stops wildlife and debris falling into the hearth
  • Works in the summer to keep your house cool

  • Has industry reassurance as the only chimney draught excluder to hold a BBA certificate
  • Made in the UK at our factory here in Maryport using Herdwick wool collected during our Operation Wool project

This Chimney Sheep is suitable for large chimneys that are 9″ – 13″ deep (230 – 330mm) by 28″ – 34″ wide (710 – 870mm). Make sure the Chimney Sheep is at least two inches bigger on each dimension than the chimney you are fitting it into with this size. It comes with a pair of 6″ handles and 6″ extension rods, giving 12″ of reach altogether. If you’re not sure what size to get, have a look at our sizing chart.

Description

How does a Chimney Sheep® draught excluder work? 

A Chimney Sheep®  draught excluder is made from highly durable and naturally breathable Herdwick wool, from a Herdwick sheep. The wool is treated with a unique ionic protect plasma which makes it 100% moth proof and aids with the longevity of the Chimney Sheep® (we have customers that have had the same ones for nearly 10 years!). It is then felted to create a unique flexible yet sturdy material. This makes the Chimney Sheep® perfect to plug the gap just above a fireplace.

The woollen pad of the Chimney Sheep® compresses to fit perfectly flues of all shapes and sizes making it far more efficient than any other chimney draught excluder on the market.  Inflatable chimney blockers and chimney umbrellas require a small gap to be left in your flue to allow ventilation but because wool is naturally breathable, a Chimney Sheep® doesn’t require that gap. Instead, 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, whilst naturally permitting sufficient ventilation. It works to prevent warm air from escaping up the chimney and stopping cold air from coming in via the chimney when not in use, reducing the ‘stack effect’ phenomenon.

It is as simple as that! Read more about the stack effect and how a Chimney Sheep® works here. 

 

What are the benefits of using a Chimney Sheep® draught excluder?

The list is endless but here are a few of the main benefits:

  • Reduces your energy bills – a Chimney Sheep® stops about 5% of your household heat from escaping, reducing your heating bill by about £99 per year on average. You can estimate how much your home might save in energy costs by using our savings calculator.
  • Reduces your carbon footprint – a Chimney Sheep® makes your heating more efficient, reducing your CO2 output by up to 250kg per year.
  • 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…).
  • 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!
  • Works in the summer – a Chimney Sheep® prevents hot air from entering your home and retains air-conditioned air, keeping your house cool in the summer.
  • Reduces air pollution in the home – a Chimney Sheep® reduces the number of air changes in a property so considerably reduces the amount of air pollution that enters the home.

 

Does a Chimney Sheep® REALLY work?

It really does! Don’t take our word for it, here is all the evidence:

  • We are the only chimney draught excluder to have a BBA Agrément Certificate. The achieve this the Chimney Sheep® had to go through numerous laboratory tests, on-site evaluations, quality management checks and product inspections, over several years, passing all the assessments to gain the award. The BBA is a worldwide credible industry body and the certificate means that Chimney Sheep® are recognised by building control, government departments, specifiers, and insurers as meeting the BBA’s standards of quality, safety and reliability. It provides you and them with reassurance of the product’s fitness for purpose.
  • Rigorously tested by BSRIA and the University of Liverpool which showed that a Chimney Sheep® will stop around 5% of household heat from escaping and therefore save users around £99 off the heating bill per year, per chimney and up to 250kg of CO2 per year chimney, working to reduce energy bills going into winter.
  • Hailed as one of Grand Designs host, Kevin McCloud’s ‘Green Heroes’.

  • Chimney Sheep® has been featured in the press quite a bit too, from the likes of The Guardian, The Times, Good Housekeeping and Ideal Home. You can have a look at some of the latest articles we’ve been featured in here.

 

Are Chimney Sheep® sustainably made?

Absolutely. We are really passionate about the environment and sustainability. Everything from our sourcing of wool to our packaging is chosen with the environment in mind and the aim of our reducing our carbon footprint as much as we can.

All Chimney Sheep® are made here in our factory in Maryport, Cumbria, using Herdwick wool sustainably sourced from farmers around Cumbria. We collect the wool once a year which we call our ‘Operation Wool’ project. We pay the local farmers a fair price for this which is usually more than the market price and helps to support them.

The felt head of a Chimney Sheep® usually lasts about 10 years and is 100% wool which means it is completely biodegradable and compostable. The handles are made with recyclable plastic therefore are extremely durable and designed to last for decades. We have designed them so that when the felt head does wear out, you can just replace it with a new felt head and keep the same handle to reduce waste and the use of excess plastic. When the time comes and you have to say goodbye to your felt head, get in touch with us.

By using a Chimney Sheep® you are doing your bit to reduce your carbon footprint and we are really passionate about helping you to reduce your CO2 output even further. That is why we have set up our very own Community Interest Company, Buy Land Plant Trees, so that with each purchase a proportion of the profits will go towards planting trees on agriculturally poor land.

How do I work out what size of Chimney Sheep® I need?

All you need to do is measure your chimney. We promise, it sounds more complicated than it really is! Head over to our simple instructions which walk you through it. If you do have any trouble though, just get in touch and we can help.

Our standard Chimney Sheep sizes will fit the majority of chimney flues. However, each and every chimney (like us!) is unique so if your chimney doesn’t look like it will fit one of our standard sizes, contact us with the measurements and we will give you a quote for a made-to-measure Chimney Sheep® that will fit your chimney perfectly.

    Ewe beaut

    Product arrived promptly, was easy to fit and works like a treat.

  2. Pichon Véronique et Benoît

    Very Happy

    We are happy for this product

  3. Gary

    Perfect Fit

    The reason that you need an extra inch all the way around is so that it fits snugly in the hole. We have noticed an immediate improvement in the room temperature after getting rid of the previous owners black bin bags filled with newspaper!

  4. Pete

    Does the Job

    Seems well made and was easy to fit ( beware of dust/grit in your eyes). Instant reduction in noise and draught and the room is definitely warmer.

    Looked at balloons but the inside of my chimney is very rough and I don’t think that they would have worked. I think that this will last for many years.

  5. Beverly

    Should have done this before

    Easy to use and sustainable fabric. We have an inglenook and it really prevents the draught from the chimney. Thank you.

  6. Neil

    Perfect

    The ambient temperature is a lot better. With my thermostats just outside the room with the chimney it was going on and off all he time. Now there is not a breeze going through to the hall the temperature is more constant. We now don’t feel a chill coming from the chimney. Wish we did it years ago!

    trina25252@me.com

    Definitely stopped the ‘draft’ – expensive but think it will pay for itself quickly – bought a large size

  8. Linda

    Best investment made

    Very very pleased front room is so much warmer.
    Best 65.00 spent in years.

    Sixth purchase

    Installed a few last winter in a late Victorian house that lies about half a mile back from the River Mersey, where winds are frequent. Felt a difference immediately in terms of warmth / lack of drafts coming down the chimney. Knowing how incorrectly installed installation of any kind can cause condensation issues, I waited til this winter to see if any issues arose. None whatsoever. So I just bought enough to complete all the chimneys. As it can hard to lay on your back with grates etc in the way, I put a bean bag in a bin liner to avoid it getting dusty then lay on it to get myself at the right angle. Job done.
