How to Choose the right Chimney Cowl
How do I know which is the right item?
If the problem (smoke or fumes coming out the fireplace or stove) occurs only in windy conditions then this is a downdraught. The anti downdraught chimney cowls to use are: A) A Static Anti Down Draught Chimney Cowl if your problem is not severe, can be found here. B) A Spinner Anti Downdraught Chimney Cowl if the your problem is severe and your chimney is over 6m in length can be found here. C) A H Anti Downdraught Chimney Cowl if your problem is severe but your chimney is shorter than 6m can be found here.
Lack of Draught:
If the problem (smoke or fumes coming out the fireplace or stove) occurs when there is little or no wind, then this is not a downdraught. This is a lack of draught. Anti downdraught chimney cowls are not effective at resolving a lack of draught, therefore do not purchase one, there is only type of chimney cowl to solve a lack of draught and that is an Electric Fan Chimney Cowl.
Too Much Draught / Fuel Use / Noise / Up-Down Problem:
A Chimney Control can be used to resolve all of these problems, however, it can only be fitted to an solid fuel open fireplace. The Chimney Control can also be used to prevent an up/down problem. An up/down problem is when smoke rises up and out of one chimney and is sucked back down an adjoining chimney pot. A Modified Static can be fitted on a chimney serving a stove. It will help prevent a chimney creating too much draught or burning too much fuel only. It will not stop noise or an up-down problem described earlier.
Nesting Birds / Rain Penetration:
Please read each of the chimney cowls descriptions on their individual product page for more in-depth information. There are also product brochures available in our resource centre that you can download.
