Chimneys: A Hidden Source of Energy Savings

Chimneys: A Hidden Source of Energy Savings

Lancaster University recently teamed up with Cumbria Eco-firm Chimney Sheep Ltd for a collaborative piece of work. Chimney Sheep Ltd manufacture and sell an innovative energy saving chimney draught excluder. Made of felted sheep wool, the Chimney Sheep® fits snugly into the chimney throat just above the fireplace and prevents warm air from escaping up the chimney when the fire isn’t lit. It also prevents cold air from sinking down. They recently celebrated five years in business, and sales have grown steadily year on year. They had the product tested by BSRIA who demonstrated that it saves around 260kg of CO² per chimney per year.

As part of Lancaster University’s ongoing work with local businesses, the Centre for Global Eco-Innovation team offered to calculate the cumulative carbon savings of Chimney Sheep sold over the years. Sales have topped 40,000 but some "sheep" have been in use for 5 years while others have only been in situ for a matter of months. The results show that not only does fitting a Chimney Sheep make the home more comfortable, they help to do their bit for the environment as well.

To date, Chimney Sheep have saved 19,856 tonnes of CO² and have saved households across the UK £2,895,793.This total carbon saving is the equivalent to the CO2 sequestered by 23,388 acres of forest in a year. With nearly 11 million chimneys across the UK the carbon saving potential of a Chimney Sheep is huge!
