How to Install an Extraction Fan on Partition Wall (to Neighbours)

nachtvlinders

The nearest outside wall is across the room to the window wall. I've asked some tradesmen but they tell me it wouldn't be possible to fit a fan. Is this true? It's so much hassle to keep cleaning tops of cupboards for the grease to build-up so regularly. Is there an alternative option? 

TIA.

You can get non-vented cooker hoods that have replaceable filters. Our old one was reasonable but I rarely fry anything.

Alternatively you could get slim line vent piping such as this https://www.toolstation.com/100-flat-channel/p39632 that could be boxed into the corners or possibly run in the ceiling between rafters depending on the construction of the property. Bear in mind it needs a powerful fan as each 90 degree angle is equivalent to 5 metres of horizontal pipe.

Is this over your stove?  A hood with filter could help clean up the air.  Or a bigger job and a duct to the outside wall.

No it's not true. Unless something you are not showing us is in the way

Which way do the joist run

You can mount duct under selling if need to

Thanks folks for replying so quick.

I wouldn't know which way the joists are run. I remember the tradesman said that the ducting can be done, but it'll look unslightly (at the time, I was put off by this, but now I'm thinking I will get it done). 

Yes, it'll be above the cooker. I do a lot of steaming and some frying. The ceiling paint is peeling so I'm kind of desperate to get this sorted ASAP. I'm not sure how much it'll cost (hopefully less than £500 all in from someone to do the job for me.) 

I'll have a gander of the fans that you've suggested.

It might be possible to run under floor. If not, the slimline ducting (225 flat) set into the plasterboard only sticks out 15 - 18mm because of the thickness of the plaster and ceiling plasterboard. I have done exactly this in a kitchen extension with a solid (low) roof and it looks fine. You don't even notice it.

It would help a lot, I think, if you posted some photos of the kitchen layout, and where the pipe needs to exit.

Recirculating hoods do nothing to get rid of steam. You need something ducted to outside - For a another 6mm depth, I'd go for the 204x60 stuff - https://www.screwfix.com/p/manrose-204-x-60mm-flat-channel-1m/59769 - Run it across the top of the wall cupboards (if possible) and it will be out of sight. Manrose also do a 225x25mm and 300x25mm rigid ducting, but suppliers are limited (so probably expensive).

I think you are out on the equivalent distance for bends - 1-1.5m per 90° is nearer the mark. You also need to keep any flexible ducting to a minimum and ensure it is pulled taught to reduce air flow resistance.

Recirculating hoods do nothing to get rid of steam, but the specific problem the OP has mentioned is not humidity and condensation but greasy cupboard tops. A recirculating cooker hood with regularly cleaned metal mesh grease filters plus replaceable active charcoal filters for odours should help with this, even if of it isn't as effective as a hood with ducted extract.

If there are cupboards between the cooker and the wll with the window, then you could put a duct through them.  It would be hidden and if put high up at the back, would only take up space that is not usually used.

Coming from the other direction, is moving the cooker/hob to the outside wall an option?
