Downdraft


We get a fair amount of downdraft down our chimney so was thinking of getting one of these installed
http://www.fluesystems.com/shop/Colt_Rotorvent.html
We rarely use the gas fire in the fire place but the design of the fire protrudes a good distance from the face of the fireplace and previous attempts to make a box to put in front of the fire (when not in use) have not really be successful. It would be tempting to push something up the chimney to block it but this would be a silly solution for a variety of reasons and may well be illegal and certainly lethal if you forgot to remove it !
Anyone had any experience or know anything about these rotary systems ?

Re: Downdraft

We had issues like this at our previous house where the brick built chimney stuck out from the outside wall. The problem was that when it was cold the sinking cold air came down the chimney so there was still a draft even on totally windless days. For that reason I'm not sure that a Rotorvent would be effective at all times.

Old/cheap umbrella cut it to fit, tie a line to it and have that outside the fire place.  Put a sign on it remove attached before using the fire
