H Chimney Cowl - St/St Grade 430 - Gas - 125mm

178.67 (Including VAT at 20%)

Availability: Usually dispatched the next working day.

The H Cowl is probably the ultimate static anti downdraught chimney cowl, as it completely isolates the combustion gases from the prevailing winds.

Manufactured using stainless steel grade 430, and with mesh inserts at the exits, makes this H Cowl suitable for use with appliances fired by oil or gas. Please note that this H Cowl is NOT suitable for use with appliances fired by solid fuel. Please see the solid fuel versions that we have available.

Suitable for use with 125mm internal diameter pipes.

Fitting Instructions
The H cowl has a shaft which is just slightly under the diameter of the cowl, so for example, a 125mm H Cowl will have a shaft with a diameter of around 120mm. It then slides inside the chimney or flue system.

Fitting to a prefabricated chimney system
Slide the cowl inside the chimney system. Secure in place with stainless steel self tapping screws and seal with a high temperature silicone or sealant.

Fitting to a masonry chimney stack or pot
Slide inside the chimney or pot and mortar in place.

  H Cowl  Just the job to stop a smokey room. Smoke goes out of the flue and not the fire. Would recomend to any one that has a stove."EXCELLENT"   (14/09/2011) John - Kells


  h cowl do they work   FANTASTIC !!!! I live on the shore line and the winds are gale force .I bought and tried every cowl known to man spinners / down draught preventers and the dragon head. non of them worked ( this is the one the H cowl since I fitted it we've had gale force winds f and no down draughts ITS A WINNER   (17/01/2016) gary - south wales


  So far so good  We have a Rayburn, which with some wind directions we got exhaust gases coming back down the flue into the kitchen. Since installing this cowl, we've not had any problems!   (07/12/2018) Paul - Hereford


  Guaranteed Solution at a Price  The H cowl is going to prevent any downdraught, no question, as the combustion gasses and prevailing wind are completely isolated from each other. The downsides are that it's physically large and, ioho, ugly. There is no fixing method as such, it needs to be cemented in place. Does the job though.   (07/05/2011) fluesystems.com - High Wycombe
