Stops downdrafts and saves fuel!
An aerodynamically designed unit which, when fitted to structurally sound chimneys and flues, completely eliminates downdraft and thereby prevents troublesome smoke and toxic fumes which otherwise would linger in the home.
The Aerocowl's built-in bleeding system reduces excessive fuel burning which results in significant savings in consumption on all types of heating appliances, whether solid fuel, oil or gas. Preliminary tests have recorded a minimum savings of 12% after fitting an Aerocowl with up to 30% recorded in certain cases. 5" and 6" round bases are to be used with 12" Aerocowl 7",8" and 10" round bases are to be used with 18" Aerocowl (for use with metal chimney liners).
