Venting cooker hood - no hole in the wall

[Martha123]

I have inherited this Lamona cooker hood, which has ducting towards the external wall but then there is no hole outside? Is this a mistake?? Where else could the extracted air be going?

Not all cooker hoods extract to the outside. Some merely filter and recirculate the air.
Some have the option of operating in either mode.

What does the white painted boxing lead to on the outside wall? Eidt: I see, nothing.

To me it looks like there may be a vent above what appears to be a black plate above the boiler flue. I would imagine they had to instal that to prevent fumes from the boiler getting drawn back into the cooker hood. Either that or a vent could not be installed because of the boiler flue. You could have a different flue installed that will take the fumes up above the position any vent for the extractor would need to go. I would suggest getting a gas safe engineer in to do both jobs as a recirculating extractor is a complete waste of time in my humble opinion.

The cement patch below the plate looks to be the right position for the extractor exit. I found one that had been ducted into the cavity of a block of flats. Must have been a right state as the kitchen ceiling was dripping with grease, and the windowsill was covered in chicken bones stuck to grease from when they lob their rubbish out. Some kitchen fans can work on recirculation if they have a carbon filter fitted in them.

maybe the builders, or the person seling the flat, wanted to trick people into thinking there was an extractor, without the effort of drilling through the wall.

A recirculating hood just sends the steam back into the kitchen, and is little more than an expensive ornament.

At best recirculation collects some of the grease, it does nothing to help reduce the moisture and cooking smells.

I know, but without the right filter it will be a lot worse. The OP should check their fan.

Thanks for the replies. There aren't carbon filters on the fan so I don't think it is recirculation. If it was then the white boxing is even more baffling.

I checked above the metal plate outsideand there isn't a vent.

The cement patch to the right has been done recently - our builder said it wasn't the extractor exit..but he could've been wrong..

We've got damp issues and the property wasn't well looked after before so hoping getting this sorted will help

Don't ask a builder get a gas safe engineer to advise. There are regulations covering the situation you have if you wish to vent the extractor through the existing trunking.
