How does a Chimney Sheep® draught excluder work?

A chimney syphons air out of a building ALL THE TIME, not just when the fire is lit. 80 cubic metres of air flow up a chimney per hour. This removes all the lovely expensive centrally heated warm air from a room. The air needs to be replaced so it drags in cold air from around doors, windows, and other leaky parts of the building. This creates the cold air that we feel. If you plug the chimney, you will cut out that syphon effect and drastically cut other cold draughts at the same time.

The Chimney Sheep® is a thick pad of Herdwick felt that lodges in the throat of the chimney just above the fireplace. It needs to be a bit bigger than the opening to hold itself in place. It plugs the gap and stops warm air escaping, plus prevents cold air from sinking down.

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 over 10 years.

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 £150 or so. 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.
  • Reduces wind noise – those horrendous howling winds coming through your chimney can be reduced and sometimes stopped altogether 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. To 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 £96 per year on average (based on the current Energy Price Cap of £1,928), 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’.
  • DIY Doctor 5* review – read the full review, here.
  • 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.

 

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 Workington, 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.

A Chinese in Atlanta
Format: Kindle
The Girl Downstairs was a charming book. Although the writing isn’t particularly sophisticated, it felt like Jo was letting us peek into the pages of her diary—raw, honest, and deeply personal. Her journey, as the main character, was both heartwarming and heartbreaking. Through her eyes, we witness the simple beauty of connection and the ugly truth of prejudice that has plagued our country for far too long. It’s a powerful reminder that humanity should never be measured by the color of one’s skin. This is another great YA read—I highly recommend it.

Atlanta During the 1890's
Format: Paperback
Whether you like The Downstairs Girl or not depends on what you crave. If you crave historical fiction that will teach you, or that helps you realize the myriad of things that were going on in a certian place and time (Atlanta during the 1890s, or an imaginative author who never use trite metaphors or similes, you will love this book. Or if you want to quickly turn pages, you will be disappointed. If you want a simple plot, do not read this book. If you want an intricately spun story with plenty of mystrey, humor and many surprises, you will love it. Jo Kuan is a Chinese American without voting rights, deStined to be a servang and doesn;t knw who her mother or father are, lives in a basement of a family with Old Gin who she thinks of as old man who adopted not offically but out of love. Chinese Americans were brought into the South after the Civil War to take over what slaves used to do but instead of no pay, they got tiny pay. You could walk or take a streetcar to work. Blacks sat the back of the streetcars, but if you were Chinese American, you didn't know where you sat or were told to gat off. They could not own or rent, where were you supposed to live; It was the start of Jim Crow laws and of cocoa cola. Women suffragettes started working towards the vote of white women. This was not a quiet oeriod of history. I thoroughly enjoyed this peak at Atlanta in the 1890's through an Asian American young woman's eyes, ears and even her nose.
