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.

My rosacea approves
Size: 3 Fl Oz (Pack of 1)
I have Rosacea, dry, sensitive, reactive skin and perimenopausal skin. My rosacea products tends to dry my already dry skin and this has been been a great moisturizer. My skin looks dewy, dullness and dryness have improved in just 2 days; I haven't reacted with sting and redness like I usually do and when I wake up I still have a dewy not greasy face even though I sleep on my sides and toss and turn all night. Definitely going to buy again since the bottle size is good, a lil goes a long way and does not make my face react like the CeraVe.

This stuff works nicely
Size: 3 Fl Oz (Pack of 1)
So I don't typically leave reviews, but I feel like this lotion has been fantastic to me. I typically don't use lotion because I hate the feel, but my face really needed it. I have dry/oily skin. My skin gets gross and flaky, yet it's pretty oily. I've always dealt with it. I decided to go ahead and buy this stuff because I couldn't take my dry skin. It helps soooo much and you barely need any. I use a dime sized amount and really focus on my problem areas. It lasts all day, not too thick and not too watery. Not greasy at all for me and soaks in very nicely. Again, it lasts all day and I don't need touch ups, even on bad skin days. I don't ever break out and it's never clogged my pores, but to be fair I've never really had skin that's broken out much before. The one thing I did notice, before using this stuff I started noticing more fine lines around my eyes/forehead. I've been using this stuff for about a year and you can barely see them anymore. I have haven't changed my diet, it's pretty atrocious honestly, so I really feel this lotion has worked wonders on its own. Also I still have a decent amount left in the bottle and I bought it almost a year ago. I'm going to try their body lotion next. Hope this helps, or at least give it a whirl!

Excellent for hydrating & moisturizing super gentle
Size: 3 Fl Oz (Pack of 1)
I really am quite amazed by this product. I’ve been using top anti aging skincare from a very prestigious, high-end brand for a long time. I’m amazed at how inexpensive this product is and how lightweight, gentle and moisturizing it as. I’m really happy I found it. It’s really incredible for hydrating and skin that is very well hydrated looks act younger. My prior anti-aging moisturizer just never moisturized THIS well. Unbelievable . My skin looks younger .

Amazing moisturizer for all skin types!
Size: 19 Ounce (Pack of 1)
I absolutely love this CeraVe Moisturizing Cream! It keeps my skin soft, smooth, and well-hydrated all day long. I use it on both my face and body, and it doesn’t feel greasy at all. It’s very gentle and perfect even for sensitive skin. I also like that it has no strong scent. A little goes a long way, and the size is great for the price. I highly recommend this product to anyone looking for a reliable daily moisturizer!
