Chimney & Fireplace

Does a chimney need ventilation??

Anonymous user 23 February 2024 - 2.35 PM

Hi, i have recently taken out our old 80's style gas fire (don't worry, i employed a gas sefe engineer to do it), however it has exposed the old hole in the chimey breast, where a fire used to be, but living in bristol we can't have an open fire so am going to have to board it up with some plaster board. Do i need to put a vent in the plasterboard so that air can circulate inside the chimney breast?? I have been told this needs to be done, but thought i'd ask the experts first. cheers.

Are you a tradesperson and able to answer this question?

yes ,but dont use plasterboard as there is always moisture inside a chimney,do it properly and use blockwork,also render front of blocks with waterproof additive and skim whole breast to a smooth finish ,this way you dont see joints,then buy a nice brushed aluminium vent and fit surface ,might cost a bit more but if you want a good finish in building it does,there are no bargains to be had in building,ho ho ho

Yes vent the bottom and fit a rain guard cowl to top of stack. If you dont have good air circulation you will have condensation problems.

Living in a smoke control area like Bristol does not mean that you cannot have a fire, it just means you have to burn smokeless fuels. Check this link out for what is okay to burn:- http://smokecontrol.defra.gov.uk/fuels.php?country=e Otherwise all the advice above is sound.

yes you need to allow good ventilation and allow the air to circulate in the chimney stack this reduces condensation
