The Chimney Balloon was created by engineer and inventor David Woodman in the late 1980’s. He and his wife Irene developed the Chimney Balloon Co, and back in the days when there was no internet, grew it into an international business. When the patent expired in 2012 there was a flurry of cheap copies that appeared on the market. These were made by attempting to reverse engineer the Balloon but failed to appreciate some of the finer details. The Chimney Balloon remains the most effective and safest of the inflatable chimney draught excluders.
The Balloon is made by Watford Workshop, a charity which gives work experience, skills training and employment for disabled and disadvantaged people. Watford Workshop have made hundreds of thousands of Chimney Balloons with strict quality control at each stage of production.
