H Cowl - prevents down draughts & encourages updraught in a chimney

H Cowl

The H Cowl is probabally the most effective chimney cowl when it comes to combating chimney down draught. When a down draught occurs in your chimney it blows down the vertical tubes on each side of the H Cowl back outside in to the athmosphere and not into your livingroom. It also accelerates venting as the cold air in the vertical tubes pass and pulls the warm air in the horizontal tube. Which pushes the chimney smoke out into the outside athmosphere.
