Use our clever calculators to see how much warm air is escaping up your chimney and how much you could save with a Chimney Sheep.
The Chimney Sheep ® is low tech and easy to use, but you need to have an idea of the size and shape of your fireplace.
Every chimney in the country seems to be different but luckily the wool compresses into a range of different shapes and sizes.
How much heat are you losing up your chimney? Chimneys are cleverly designed to draw air up and out of a building. If you’ve got the central heating on and the fire isn’t lit, all your precious warm air will disappear up the flue within an hour. Just put your hand in the flue and you’ll be astonished by how strong the chimney draught is. This escaping air needs to be replaced, so cold air is pulled in from under doors and round windows, creating the cold draughts we feel. Now you can stop chimney draughts and reduce chimney heat loss with a Chimney Sheep®! The Chimney Sheep® is a thick layer of felted wool on a handle that plugs the gap just above the fireplace preventing warm air from escaping up the chimney and stopping cold air from coming down the chimney.
Fitting a chimney sheep will save around 4% off your heating bill. That means it should pay for itself within 6 months.
Tests have shown that it also reduces the amount of pollution entering the home.
Having an open chimney is like leaving a window open all the time. Fitting a Chimney Sheep® effectively closes the window.
A lot of happy customers tell us their homes are quieter since they fitted a chimney sheep.
Thanks for the note with my recently delivered chimney sheep regarding the long rod flexibility. I did have a problem installing it as it requires a degree of force (the throat is 11inches square for a 15inch round chimney sheep). Also, the slopes into the throat are different on each side as the chimney is diverting from the vertical, so this tends to cause the felt pad to rotate from the horizontal and the extension rod then buckles under the force. Fortunately, your note gave me a clue and I used a piece of plastic basin drain pipe cut to length. This worked perfectly, especially when used to tap the felt into place rather than just push it. I’ve now got a well sealed chimney, and just in time as it is windy tonight.
Super fast delivery, great item that works perfectly.
