“The main problem my dad was having with his Tiger stove was the smoke it was producing. The stove is in a single storey extension with flat roof and the neighbour was complaining the smoke was blowing into her kitchen! Even using wood that was purchased as “dry” it was smoking and also it didnt seem to be drawing properly and smoke was backing up through the vents into the room. As soon as the Cube was fitted we lit the stove to see if it had resolved any of the problems. It took about 4-5 minutes for the stove to warm up and then the smoke just vanished leaving only a heat shimmer visible..The smoke hasn’t come back into the room either so hopefully this problem has stopped too.. My dad is more than happy with the cube and would happily recommend it/you to anyone”
