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.
Managed to get my chimney sheep up the chimney. Not easy as I have to reach behind the protruding hood & narrow opening, and it is a bit squished as I couldn’t get it all the way up, but it now provides a solid block and I can’t believe how much warmer the whole downstairs is. Previously the room with the chimney was always much colder since it faced north as well. Even secondary glazing didn’t help all that much, nor the foil insulation sheet behind radiator and also in front of the damper we had put in, but now it is almost as warm as back of house! Very impressed. Wish I’d bought it 10 years ago (but maybe you weren’t around then!) Only problem will be getting it in and out when we have the occasional real fire, but I suspect practice will make perfect.

We are very happy with the packaging and delivery of the Sheep this morning, and it’s all its place in the chimney already.
