Cooker hood ventilation

[oddpodd]

We are planning our new kitchen and we are fitting a cooker hood. The problem is how to vent it externally!

The cooker against an internal wall so we cannot vent to the rear.
We could vent to the right, to an external wall 3 feet away, but this is next to a pavement. Is this a problem?

Also, if we go right, will I have to cut a piece out of the side of the vertical part of the hood as it only vents rearwards.

Finally, what is the best way of tidying / hiding the ducting? It cannot go in to ceiling space (floor joists in the way) and we have no cupboards by the cooker to hide them above.

Cheers

Sounds to me like you need to re-site the hood!

Using flat rectangular ducting can be a more discreet way to exhaust an extractor, as it can be orientated so that it sits flat against a wall or ceiling.

It would still need boxing in but would turn out less bulky than flexi hose.

Good answer, Noseall But what about the pavement-- vindaloo @ all hours ....Getting IN through the duct

We are talking about Baarth (says in a posh voice) Nige F, not Bradford.

Rectangular ducting sounds good. Thanks guys.

Check the size of the ducting. If your using a big hood 100mm will not be good enough, flat channel 125mm equivalent is quite wide, perhaps round fixed ducting would be okay.

are you sure you cant go into the ceiling and run the vents through the void?
Then you can run the vent to the external wall.

No, cant go into the ceiling, the floor joists run against the direction of the duct.

No, cant go into the ceiling, the floor joists run against the direction of the duct.

So can you not take the ducting out parallel with the joists to an external wall? How long would the run be to take the ducting out alongside the joists?

 

[oddpodd]

To run parallel, the ducting would have to be about 3 meters long, but it would then have to exit through a pitched roof of a single story extension. I think the best option is to run it to the right, about 3 feet and box in the flue?
