  • Duct Kitchen Hood India

Know your Duct Kitchen Hood well before buying

Kitchen Hood/ chimney is a great way to enrich the kitchen environment. There are basically 2 types of chimney- Ductable chimney and Recyclable chimney.

Ductable chimney also called as vented chimneys, channels out the smoke, heat and other impure gases out through a PVC or aluminum pipes. Ductable chimneys are best and preferred for Indian kitchens. Also the performance of ductable chimneys is much better than recyclable ones.

Before buying ductable chimneys, home owners shall take care of few important details like space availability, ducting length, diameter, bends, etc. for better and long lasting performance.

Duct Space Availability – Before buying kitchen hood, home owner shall find out if there is space or any kind of provision given/available to install a ductable chimney. A hole, slightly bigger than 6” is required for ducting purpose. If at all this is not done, home owners can request dealers to get the breaking and brick word done as required. This work would be an added cost for home owners wanting to install ductable chimneys.

Size of Duct Pipe – Usually 6 feet pipe is given along with the chimney. If the duct hole is more in length than 6 feet, than an additional pipe can be bought and fixed. A 10 feet height for ducts is usually recommended for Indian kitchens. You may happen to find ducts of 13 feet-15 feet in Indian home, which I wouldn’t suggest home owners to have. But a minimum of 6 feet to 8 feet height of duct is necessary to maintain the productivity of chimney.

Bends in Duct – The duct installed shall have least number of bends from chimney to the duct hole. More the number of bends, the efficiency of the chimney reduces and the noise level increases. The rule of thumb here is to have as much as only 3 bends in duct. (Here we talking about 90 degree bends). A good dealer will never recommend more than 3 bends for ducts. If there are bends at 45 degree than 1 or 2 additional bends. Few companies like SIMENS (a German company) notify home owners for having only 2 bends (that is if required) in ducts. A third bend is prohibited to make sure the performance is reached.

But with advanced technology, few companies have introduced “Flexible ducts” concept. The standard length of duct is 3 meters in with 3”-18” in diameter. This flexible duct pipe comes in 1 meter which is stretched to 3 meter, is highly resistant to corrosion can easily to install. But I suggest you to check other technical features of Kitchen Chimneys with Flexible duct before buying to ensure it suits your kitchen requirements.

      For Commercial Kitchens, you need to buy heavy duty chimneys. Please check local market price for branded & non branded ones.

    Hi, Thanks for sharing this informative article. I am planning to install a chimney in my kitchen. My chimney ducting pipe length comes to around 21 feet and will have atleast 3 (may be 4) bends.
    In your expert opinion should I go for ductable chimney or not given the specifications and constraints above? What suction capacity and brand of chimney should I buy?
    Thank you.

    Useful article. Thanks. Two questions: Will a chimney with a CFM capacity of 1500 work effectively with a ducting pipe of 4″ diameter? And is it necessary to break the wall for the ducting? Why not fit the ducting pipe on the surface of the wall?

    Will appreciate your insights on the queries.

    Thank you.

      Deepak ji, regarding capacity, there are other factors that factor – length of the duct, any bends in the duct. Chimney Company representatives are suppose to inspect site & tell you accurate answer.

      I do not correctly understand your second question. Chimney is more effective if duct length is smaller i.e chimney has to as little work as possible. Nearest wall in which you can make cut & allow duct to pass, so tht fumes & exhaust is thrown out.

      Most homes end up using duct of 4″ to 6″ . Here’s the thing – how many bends are in the duct way, how long is the duct, all these things matter. You may end up using duct of any size, but only company expert or your kitchen designer can tell you if its been designed efficiently. If not done correctly, chimney may not work as efficiently as it can. Many a times, chimney makes extra noise, just because ducting was not done correctly. I am making your situation tough, but all I am trying to say is, verify it with expert. Make someone actually check your design before going ahead.

    Hi.. I want to install a kitchen chimney but we need a long pipe (16 to 18 ft) and two bends . We were suggested a 1400 suction capacity chimney due to pipe length. Is this suggestion wise. Can u suggest if we can have some lower capacity chimney too.

    • contractorbhai 15 August 2016 at 11:55 am - Reply

      Shubhadeep ji, this sounds like unique/complex situation. You will have to talk to local Kitchen/Chimney expert. Honestly, we are not sure if lower capacity chimney will do the job, also there are several other factors like kitchen design, kitchen usage, etc.

      Madhu ji, please check which company/brand gives good warranty & service in your area. Also before mkaing decision make sure your kitchen designer or chimney company representative has seen your kitchen & given YES for chimney model. Take pictures & dimensions of your kitchen to chimney shop.

    what is constructional differance between recyclable & ductable chimaney ? is activated charcoal disc provided in both cases ? plz. mail if possible .

    • contractorbhai 26 August 2016 at 4:55 pm - Reply

      ductable chimneys are suppose to route air out through duct, whereas recyclable filters air & keeps it inside room. charcoal filters & similar other filters are more common with recylable one.

      Tiwari ji, you need to talk to manufacturer or nearby kitchen designer. Connecting ducts of different size is done at many site, but you need to check it with manufacturer.

      depends on lot of other factors – like capacity, if there are any turns & how long is duct – pls confirm it with brand/manufacturer or shop where you purchased.

    Is ductable or non ductable more effective? As I am confused because i don’t know that after suction of hot air where does the air go as it has no outlet to go out and will that make my kitchen feel more hotter.
