Well after nearly two years, the kitchen is approaching completion. Had Mr
Corgi over to connect the gas hob and 'er indoors decided to try it out by
boiling stuff for about 100 years on all four rings. You can imagine the
condensation!

I wasn't going to bother with a hood, but now I see that it might be
sensible to actually install one.

My problem is that the hob is not near an outside wall. I have looked at
hoods generally and see that most of them are vented through the wall. A few
are "island" hoods that vent vertically.

How do these things actually get vented to outside? A long flexible like a
tumble dryer pipe?

I need something that vents straight up then moves 90 degrees to follow
the ceiling joists, before exiting. A distance of two or three metres.

So I obviously know little and hoping for some education. I'm not keen on a
recirculating because I don't feel that they will deal with moist air
adequately enough.

Use Osma soil pipe (above ground).

You *can* do that, but it's not very good because of the ridges in the
pipe. It is best to use ridgid round or flat ducting with as gentle
bends as possible. You end up with a trade off between appearance
and fitting into the space vs functionality - i.e. if you run a
120x50mm duct for more than a metre or two and have sharp bends in it,
then you can expect the performance to be pretty poor.


I need something that vents straight up then moves 90 degrees to follow
the ceiling joists, before exiting. A distance of two or three metres.

If you can run the duct upwards, through the ceiling and run through
the space above, you can achieve a lot. In that case, for this
length, go for a 125mm round duct rather than a 100mm one like soil
pipe. If you are going 3m it will make a big difference even if you
use a 100mm duct hood. First it will run better and second it will be
quieter.



So I obviously know little and hoping for some education. I'm not keen on a
recirculating because I don't feel that they will deal with moist air
adequately enough.

These are completely useless. They won't do anything for moisture and
not much more for grease.

Go for a hood that vents and has removable metal filters. These can
be taken out and put in the dishwasher so cleaning is easy and there
are no consumables.

Have a look at http://www.elica.co.uk/

Elica are an Italian manufacturer who produce virtually all cooker
hoods sold in Europe, be it their own or private label for other
manufacturers.

Yes, and or with plastic box tubing. There is a kit that you can buy for the
Bosch/ Neff ones. You may well be able to buy suitable parts in one of the
sheds.

That is what mine does (well more like 1.5m horizontal.) The vertical part is
round flexible hose. The horizontal part is rectangular cross section and is
above the cupboards.

It does work very well. No condensation on kitchen windows.

OK I have more of an idea now, I have been looking at a Beaumatic QF9? Moves air at up to 500 thingys. :-)

My difficulty is in getting the vent outside without too many sharp angles
and visibility.

I just might post some pic next week for you to have a laugh at!. I will
also have to move the hope 6 inches to the left to make it look balanced if
I fit a hood.

As others have said, a flexible (ridged) hose impedes airflow, and
significantly so over long distances. If your ceiling void allows it
then smooth/rigid ducting will be far superior.

With the way the joists run, it looks like I will need a couple of sharp 90
degree bends unless I can think of another route.




In my case, being in similar circumstances to yourself, I bought a
Baumatic canopy hood from TLC
(http://www.tlc-direct.co.uk/Products/BMCAN54SS.html) which, at £100
for a 500m3/h freeflow is hard to beat. It has a 5" outlet and so I
bought a coupler (from BES?) to marry this to 6" ducting. The ducting
consisted of a 1.5m rise to the ceiling (void), a 90deg bend and a 3m
horizontal run to the outside wall. The exterior was finished with a
gravity flap as there is none such fitted to the extractor itself (and
thus would be draughty when not in use).


Interesting. The Beaumatic chimney hood is the one that caught my eye. Sadly
the white one is greatly more expensive than the stainless.
