Browse Forums Kitchen Corner 1 Dec 02, 2014 8:48 am Hi, I am building an investment property and the builder has asked where we would like the kitchen exhaust vents to be directed to? They can either send the exhaust externally, or send it into the roof cavity or recirculate it so that it is vented internally into the front hallway of the house. By default, they recirculate the exhausts into the front hallway of the house. Mind you, the Master Bedroom and 2nd bedroom are by the front of the house. The builder is currently forming a quote as per venting the exhaust externally or into the roof cavity. They do not charge any extra if the vents are just recirculated. I am opting for the exhausts to be sent externally (subject to the quote). Thanks, Re: Kitchen exhaust venting - External or Roof or Recirculat 2Dec 02, 2014 9:07 am If you have good ventilation in and out of your roof, i.e. if you have a solar powered exhaust fan on your roof, then ventilating to the roof should work very well. One of the reasons why people don't like venting in to the roof from your kitchen/bathroom/laundry, is that the exhausted air just sits in the roof and goes nowhere. With a properly ventilated ceiling space, venting in to that space isn't a problem. Owner Building at Jimboomba Woods in Logan City Qld.

Re: Kitchen exhaust venting - External or Roof or Recirculat 3Dec 02, 2014 11:04 am I'm a bit confused as to why anyone would exhaust kitchen fumes anywhere else but to outside. I'm particularly confused as to why you exhaust kitchen fumes to another part of the house. The object of the exercise is to get heat, odour and particulates out of your house, not dump it in another room or in your roof space.

Not only will it extract smells but also there are microscopic droplets of oil in the air. Ducting it into the ceiling will creat a sticky long term mess that dust will stick too Re: Kitchen exhaust venting - External or Roof or Recirculat 7Dec 02, 2014 8:24 pm All good points, particulary Bashworth.... here I was thinking that I could get away with it at my new place, but since it isn't going to be much harder at all to vent it outside, I might as well just do it that way.

Re: Kitchen exhaust venting - External or Roof or Recirculat 8Dec 03, 2014 1:07 am If I remember correctly the Australian Standards for ventilation require external ventilation through either the roof cavity or directly. I think it's in AS1668 in Section 5.10. Re: Kitchen exhaust venting - External or Roof or Recirculat 9Dec 03, 2014 9:27 pm Yes your right there you are not allowed to vent into roof cavity as it is a fire risk. If the cooktop is on an external wall than venting is easy and inexpensive, if not you can run the vent hose along the top of cabinets and out to external wall. Recirculating is a waste you might as well save your money and dont put in a rangehood if you recirculate. Re: Kitchen exhaust venting - External or Roof or Recirculat 10Dec 10, 2014 3:42 pm It has been illegal in NSW for at least fifteen years to vent a kitchen fan into the ceiling. I'd imagine it would be similar in other states. Bathrooms you can into the ceiling but is not recommended due to condensation forming.
