Great news to report in that the Windkat has successfully resolved our problem with smoke throughout our home when we lit the fire.
It's an open fire and it worked fine until we extended into the loft. This changed the roof obviously and since then we have had issues with smoke coming into the house. We hardly lit the fire last year because of it. Our chimney sweep said our fire opening was too wide (we increased that when we put in a new fireplace), however it had worked fine before extending the loft so we really wanted a solution where we didn't have to change the fire place itself.
Thanks so much and also for assisting when I ordered the wrong size of Windkat.
