A home with a short chimney in which a wood burning stove has been installed has a very good chance of suffering from downdraft and draw issues. Downdraft occurs because there isn’t enough draw due to the fact the chimney is short, smoke billows back down the chimney and into the accommodation, causing problems for residents due to toxic gases.
This is a common occurrence associated with short chimneys on bungalows, conservatories, single storey extensions, chimneys situated below the roof line or perhaps even glamping accommodation
The cause of downdraft is often related to wind direction and strength, trees, architecture or atmospheric pressure caused by mountains or valleys. Short chimneys can be more vulnerable to these external factors, so you need to take action rather then risk being smoked out or having to opening all the windows on a winter’s day.
FlueCube, “The clever chimney cowl” will solve these problems. It does this by creating a positive draw through the flue system, stabilizing the burn within the stove and thus enabling the stove to perform (burn) at a much greater efficiency consuming a larger amount of black carbon (soot) then would previously be possible. The FlueCube also enables stoves to be installed in areas of low pressure and thermal disturbance (normally restrictive for stoves).
Short Chimney Case Study
"All is well.
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 fire box of the wood burner and showed a poor draw, smoke test was then put into to 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 carried out.
He was absolutely astonished!
The draw was superb and the smoke evacuated immediately.
He was so impressed he asked me for all the details, which I gave him, website etc.etc.
He had, apparently a number of customers with not dis-similar issues. He is convinced this FlueCube cowl was 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 what so ever.
After many years of struggling with this problem my wife and I are very happy that it has been money well spent."
