Kitchen extractor fan advice

[morfa]

I'm sure there's a fair few folk on here who know about this sort of thing. I've got my cooker in an old fireplace in my kitchen. It's a standard electric cooker. The fireplace is 120cm wide. From the top of the cooker to the top of the arch there's 60 cm (to the lowest point) but it's a bit higher inside (63cm ish) as there's a false ceiling inside.

Ideally, as the chimney is on the back wall of the house, I'd like to run a short length of ducting upwards and then out through the wall. There is a utility room on the back of the house, but it's quite low, which is why the fan can't go straight outside. However I wouldn't mind if the ducting went through the top of the utility room.

I've read around a bit about this on the internet and there are some folk saying this is an awful idea and that even with the ducting the steam from the cooker will still line the chimney with grease causing a fire hazard. However there are companies that sell cooker hoods which fit in chimneys, so I guess it must be possible.

Has anyone on here had this done? Is it an option? Or should I just look at putting an extractor fan elsewhere in the kitchen?

And finally, if you're able to fit one for me, you work in/near Bridgend and want the job, drop me a PM.

Why bother with ducting? If the chimney is open then why not simply stick an extractor to vent through your false ceiling up up and away. I think that bit about a fire hazard is OTT or applies to a 24/7/365 chip-cooking industrial plant.

Is your hob gas or electric ?

It's electric. Like I said, a standard electric cooker.

I've read about places that say anything from 60cms, to 75cms being the distance between the cooker and 'combustible material'. The false ceiling is built out of aqua board (it's a cement moisture/fire resistant plasterboard) for this reason.

I f your chimney is functioning properly then I would do exactly as Roger suggests

I agree with Roger, I have a cooker hood in my kitchen which extracts in a tube up the chimney to the top (7m). I have the tube because the chimney is 2m by 1m at the bottom - yours may be a little smaller

Instinctively, the thought of venting warm, moist and possibly greasy air up a cold chimney stack does not seem right. Ideally the extraction system needs to be able to expel the 'dirty' air whilst it is still warm and able to carry moisture.

Most of the extractor hoods use a replaceable filter to remove the grease so that should reduce the problem?

Many of the "extractor hoods" with filters don't extract at all, they just filter. They are a waste of space.

phil.p - I'd say that pretty much every kitchen with a hood in it just recycles and filters. As you say, they're totally pointless.

hanser - ok, well that's one person who tallys with what others on the internet say.

alex, max and roger - thanks for the advice.

Harbo - good point, a decent hood, with filters might be a good idea fullstop, just to stop grease going up the chimney at all.

I still can't make up my mind as to which way to go, I have to say.

Our extractor hood extracts out through the nearest wall which happens to be our attached garage - my workshop.

Never had problems with grease etc - just lovely smells!

It uses a fibre cloth type filter which changes colour when in need of replacing - about every 6 months?

Hi friends,,just a word of warning when evacuating kitchen smells etc:,,I fitted a cooker extract system and was warned by our plumber to make sure if you have a gas boiler that draws air from the same rooms as the extract system to make sure you do starve the boiler of its air supply,,,

Don't take his advice, you'll kill yourselves :shock:

Most extractors these days have stainless steel mesh filters to trap the grease, which you simply unclip and pop in the dishwasher to clean
