    Hello guys,
    I want to install a cooker hood before my wife comes back from holiday, and I like this one:

    http://www.amazon.co.uk/Hotpoint-HR62X-Stainless-Steel-Cooker/dp/B000FFJVBY

    The problem is it looks like these chimney types have a chimney that goes up to the ceiling, and there does not seem to be a way to route the chimney up, then take a turn towards the wall and have the ducting exit to the outside through the wall.

    How do you do it, I have browsed this forum for an hour but have not figured that out.

    Thanks,
    Mark.

    The fan outlet should be fitted with ducting in any case (mine does)or you'll get fat stains & god knows what else running down the outside; the chimney column is really just for show & to hide the internal duct. By fitting the ducting you can exit at 90 degrees through an outlet in the wall. Does it not explain this in the instruction/installation manual?

    Hi Richard,
    Thanks for the reply.

    I have not bought it yet, just making sure I don't buy something that will not work in our house.

    The chimney looks like it goes straight up, so my concern is how to get it a pipe out the wall when the chimney does not turn towards the wall.

    You bring up something I did not consider, that there may be greasy waste dribbling out of the exhaust in our back yard (not so nice!) So what "ducting" are you talking about? Can one have a little catch tank under the exit pipe to collect the goop?

    Thanks,
    Mark.

    The stainless steel chimney is simply a cover. Inside the cover is a plastic pipe, which you can route wherever you want, but the fan may not come with pipework. You may have to buy it seperately.

    Fat wont be an issue. The metal filter pre-fan will catch most of the gunk. ;)

    Hi Steve,
    Thanks for the reply...
    The chimney -looks- like it is cylindrical, and would therefore have no hole at the back for a pipe to go out of the wall!

    That is my main question/problem, what/how to get the pipe out the wall when the chimney just goes upwards. I definitely dont want to be lifting floorboards in my bathroom above the kitchen to route the pipe out the wall between floors.

    good God, well spotted!
    I had been looking at various Hotpoint ones, all extractor ones, and did not specifically check this one.
    I guess the model Ive been looking at most is the one linked to below, which has a rectangular chimney...

    So would that mean that this one below would have an open backed chimney, or a hole so the pipe could go out of the wall?

    that's a 60cm (2-foot wide one) which is the width of an ordinary cooker. I prefer a 1000mm (three-foot four inches) hood, as it catches steam rising to the side of the cooker, and can also be used with a large range-type cooker if you decide to get one later.

    What! of course mine has grease filters but you still get some residual condensate getting through; just trying to make a point that without ducting, residual steam will condense on the inside of the chimney & ooze out of every orifice. Mine’s fitted with Marley rectangular ducting under the floorboards to an outside vent & my wall is also spotless but it's only been in 3 years; but thanks for your concern. ;)

    telemachus: holmslaw is right about recirculation hoods, they are about as much use as an ashtray on a motorbike; well spotted. Agree also with JohnD, get a hood slightly wider than the hob if your overhead units will allow it, they extract much better. If you do any series cooking I would go for a twin fan unit with the highest extract rate you can find. Many hoods are designed to look good & although they meet minimum extract regs. are not really very efficient.

    Hi there
    I can only do a max of 60cm.
    The hood I mentioned first actually CAN do external extraction, and i prefer it aesthetically, but am only worried about the chimney seems to be a tube, and therefore I cant see how I would route the extraction out of the wall.

    ps,
    i would definitely get that disgusting and hillarious oozing issue looked at
