Exit for extractor hood

Jag1978

Hi All
I’m buying a new extractor hood (baumatic 900mm) to go with my new kitchen and cooker. Currently the kitchen doesn’t have an external exit for the hood. I’m seriously contemplating having a hole made though the flat roof as there is no way to exit though the walls. A local roofer has quoted me about £100ish to have the work done. This will include making the hole and putting in a small cone type thing with a cap on top to stop the rain getting in (like a small chimney)
The question is: would it make much of a difference by having an exit oppose to a recirculation the air. I believe the hood I’m looking at allows for both options?? If it didn’t make much different then I’ll give it a miss?
Regards

£100 isn't a bad price for that. With it extarcting externally there are no filters that need cleaning/replacing and the stale air/steam/gease/smoke gets vented straight outside. It does make a lot of difference especially on a 900mm hood. Makes the kitchen much fresher.

Do you have an existing cooker hood? Do you use it much? Do you cook smelly/smokey/steamy stuff?

I'll soon be fitting a hood that will recirculate the air - as I don't already have a hood, and rarely cook anything it'll be a luxury just to be able to have the hood.

Well, my house has had tenants for the last 2 years so don't know and the previous hood was a re circulated one, prior to that I didn't cook. But I think when the kitchen has gone in I'm going to turn into a Gordon Ramsey so it might be wise to go down the chimney route!! Either that or smell the place out with all the burning!!

Most definately better to vent out! All the steam and cooking smells are taken straight outside, so no steamy windows, no lingering smells.
It is really worth the extra work, recirculating hoods need the filters changing and cleaning regularly and are just not effective!

Re-circulating devices are useless. They do nothing with steam ... and the smells just cling to the filters. And they throw grease across the walls where they vent ... where they get it from I'm unsure as we don't use fats etc on the hob!

When we had our kitchen fitted the fitter accidentally disposed of the flange that turned the hood from re-circulating to extract. Couldn't get one separately from the manufacturer so had to wait months for him to fit another hood with an unwanted baffle. In the interim had to ban the OH from using the hood - we just opened the door or window. They really are totally useless in recirculation mode. Spend the £100 .... well worth it to keep the kitchen steam / smell free.

The previous 2 replies are right - always extract. If your home is prone to condensation, then extraction is a MUST. Any thing else just doesn't make sense.
