Kitchen Fitting

Kitchen chimney breast extrator using natural draw of chimney

Anonymous user 23/02/2024 - 3.46 PM

I've recently had a new kitchen fitted and part of this was installing an electric hob and oven into an open chimney breast (which previously would have been an open fire place). The chimney open all the way up (with cowl on top). I had been advised that I wouldn't necessarily need to install an electric extrator, but rather I could board up the chimney, and install a metal sheet and a simple non-electric fan and the natural draw of the chimney breast would work as a good extrator. However, the builder who had started the job and advised this has since stopped returning calls and won't help me any further. Looking for help on what the components parts are called that I would need for this job please - and also whether the suggested install would work (I cannot vent out side the side of the house). Thanks in advance

Hi Olivia, A cooker hood extractor should have an extraction capacity 10 times the volume of the room it's installed in. For example if your kitchen measures 4mx5m and ceiling is 3m high, then the volume of your kitchen is 60 cubic meter, times that by 10 you get 600. So any extractor that has 600 cubic meter per hour will be suitable. The natural flow of air in a typical chimney is around 70/80 cubic meter which is comparably very small and most definitely inadequate. It's also worth mentioning that cooker hoods also filter the grease dissipated in air during cooking. If you simply discharge that into chimney you'll end up with a huge deposit of organic materials inside your chimney that will turn into a deadly fungal incubator sitting right on top of the food you're making!

Personally I wouldn't recommend putting grease and steam up the chimney unless it has a flue and mechanical ventilation installed.
