“Chimney sweep (Registered) came to fit the cube but expressed doubts as to its capabilities so did a before and after test.
A flame was introduced to the firebox of the wood burner and showed a poor draw, smoke test was then put into the wood burner and it floated about and did not evacuate very quickly. Exactly as the year before when he had last tested it.
The Flue Cube was then fitted and the same test was carried out.
He was absolutely astonished!
The draw was superb and the smoke was evacuated immediately.
He was so impressed he asked me for all the details, which I gave him, the website, etc.etc.
He had, apparently, a number of customers with not dis-similar issues. He is convinced this FlueCube cowl is the answer.
Because it was cold here last night we lit our wood burner to try it out properly. It lit immediately with no smoke blowback and burnt evenly and hotter than before.
There was very little debris, just fine ash, to clear out this morning.
After searching on the web and looking at different types of cowl, my wife and I saw the FlueCube and although it was more expensive than other offerings we decided, after reading the specification and its abilities, that it should be the answer to our problems.
It certainly has changed the operation of the wood burning stove significantly for the better. The glass is no longer a tar covered mess in the morning and the ash residue is fine and powdery with all the fuel completely consumed. We have had no blow back whatsoever.
After many years of struggling with this problem my wife and I are very happy that it has been money well spent."
