About the Flue Cube Chimney Cowl

The British manufactured Flue Cube is the UK’s most effective problem-solving chimney cowl, offering value-for-money by improving and completing your stove experience. It is guaranteed to work and to last. The FlueCube will fit onto a standard round Chimney Pot or Twin Wall System with an internal diameter between 127mm to 150mm (5” to 6”)

How the Flue Cube Chimney Cowl works

The FlueCube chimney cowl solves problems  such as issues with lighting your stove, the stove not reaching its optimum temperature, smoke blowing into your home when the wind comes from a certain direction or downdraft caused by surrounding trees, buildings or terrain. In all of these cases, a FlueCube chimney cowl will work for you. It also improves the efficient heating of your home while contributing to reducing your fuel bill. Saving on fuel means that you save money and help the environment.

Existing and newly installed wood burners will greatly benefit from the addition of a FlueCube chimney cowl. Your stove will produce less soot and smoke, while burning at a hotter temperature yet using your fuel more efficiently.

It achieves this by creating a positive draw through the flue system, stabilising the burn within the stove and thus enabling the stove to perform with much greater efficiency, consuming a larger amount of black carbon (soot) than would previously be possible. The FlueCube also enables stoves to be installed in areas of low pressure and thermal disturbance that are normally restrictive for stoves. In addition, the FlueCube solves problems routinely occurring with short chimneys, for example on bungalows, conservatories and single storey extensions and work spaces, or where the chimney is below the roof line.

The FlueCube is a chimney cowl designed and manufactured to improve the experience of wood burning, multi fuel stoves, oil fired stoves.

Specifications of the Flue Cube Chimney Cowl

The FlueCube Chimney Cowl is built to last. It is made from quality 316 stainless steel and has no moving parts, so won’t break. We manufacture two versions one for chimney pots and comes with all the fitting attachments and one for flue pipes that slides into the inner diameter (usually 6″or 5″ ) of the twin wall flue.The FlueCube is also bird proof, wind proof, snow proof, helps to keep out rain and helps keep your flue cleaner, providing low resin wood is burned.

Painted models are finished in high quality, high temperature stove paint.

Frequently Asked Questions

Question: How Big is a Flue Cube?

Answer: The FlueCube is 30.5cm long with a width of 30.5cm; with a choice of 4 colours, the FlueCube blends in with your current chimney. You won’t notice it is there but you will notice the benefits.

Question: How Easy is it to install a Flue Cube?

Answer: Easy to install but you need to be safe on ladders and roofs so don’t try it if your are not used ladders and roofs.

Question: How efficient will my wood burner become with a FlueCube Chimney Cowl Installed?

Answer: The FlueCube’s unique design enables the wood burning stove to burn fuel more efficiently leaving only ash dust at the bottom of your stove.

How efficient overall your wood burner becomes with a FlueCube will depend on a number of factors; the fuel you burn, make of stove, length of chimney, the location of your home, so we can’t put a definitive figure on efficiency. What we can say is our customers have all seen a positive improvement.

Question: How does the Flue Cube help the environment?

Answer: By creating a positive draw through the flue system stabilising 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. (Black Carbon is widely acknowledged to be a significant contributor to Arctic ice-melt )
Note:The FlueCube is supported by Low Carbon Kent, where we are located, because of its potential to reduce black carbon.

Choosing the Correct Size

Its sometimes difficult to choose the correct size of Chimney Cowl. We have the perfect solution and can be done from ground level as well.

If you can accurately guess the size or width of the chimney pot from the floor you can order the right Cap or Cowl from Chimney Cowl Products. The good news is this is relatively easy once you know the rough size of a house brick and the thickness of the walls of a chimney pot.

Using either the naked eye or a set of binoculars get a ‘side on’ view of the chimney pot you wish to cap or fit a chimney cowl, then find a full sized brick nearest to the chosen pot as a reference, normally directly underneath.

Now imagine that the brick is placed on top of the chimney pot itself and make a mental note whether it would fit inside, hang over, or sit flush. It may sound silly but once you know that the width of an average UK house brick is 225mm ( 9″ ) for imperial or 215 ( 8 and half ” ) on a modern property, it provides a very accurate impromptu tape measure.

The other factor you may need is internal pot size, this can also be guessed quite accurately if you know the average thickness of a chimney pot is about 25mm ( 1″ ) , simply factor this in and you can work out most chimney pot width’s quite accurately.

If you have large decorative rolls on top of the pot, make an allowance for this by guessing, using a brick as your guide.
