Types of kitchen chimneys explained when to prefer which

10 Feb 2020

How to choose the right type of chimney is just as important a question as having one. Depending upon your kitchen area and installation you can find the chimney most ideal for your needs. Types of kitchen chimneys can be sub categorised depending upon ducting and non-ducting features, design, and installation mounting.

Duct/Ductless feature

Duct in kitchen chimney

  • Chimneys with ducting pipes eliminate the hot rising air which contains harmful smoke, heat, and oil and spice particles.
  • This added feature definitely costs more, but at the same time gives a better performance as unwanted particles suspended in the air are eliminated from the cooking area.
  • This comes with hood chimneys with higher suction powers which are used in kitchens cooking strong flavourful cuisines which use more oil and spices.
  • Such high power house chimneys definitely need more maintenance, be in terms of filter, motors, or ducting pipes.
  • The ducting pipes may affect your kitchen aesthetics in case they are not built in the kitchen interiors.

Ductless kitchen chimney

  • Ductless chimneys cannot eliminate the unwanted air from the kitchen. Rather they purify the air which contains harmful smoke and blows it back into the kitchen. This makes it ineffective in regulating the heat built-up in the kitchen, and is mostly used to purify the air of odour and any pungent smell persisting after cooking.
  • This costs lesser than heavy use chimneys with elimination vents, but it also translates to poorer performance when compared.
  • It is mostly seen in chimneys with lower suction powers, like in straight-line house chimneys.
  • Such low power house chimneys need lesser maintenance as most of them would use carbon filters which cannot be cleaned, but again, the cost of changing filters every 3-6 months would be more.
  • They do not affect your kitchen aesthetics.


Chimney designs can come in either of the 2 variants; Hood or Straight-line chimneys.

Hood chimneys

As the name suggests, they have a hood to cover the area directly above the gas stoves to cover maximum heat and smoke from the cooking surface. The smoke and steam rises and the heavy grease and dirt is separated in the filters. The remaining hot air and odour moves onto the vent and is eliminated with ducting pipes.

Straight-line chimneys

Instead of hoods, they have straight-line bodies like that of split air-conditioners. They suck in the gas and smoke from the covered area over the cooking stove and purify the odour and harmful particles using charcoal filters. No air from the kitchen is eliminated and the purified air is thrown back into the kitchen, it is ineffective on the heat and the heavy smoke produced in rich and gaudy cooking. Having no ducting pipes, they are best suited for kitchens which don’t have extra place for drilling extra pipes.


Depending upon the installation process, there are three different house chimney types, classified as;

Wall-mounted Chimney

The kitchen chimney is mounted against a wall for support. They can also be corner mounted chimneys, where two sides of the chimney are supported against the walls instead of one back side.

Ceiling-mounted Chimney or Island chimney

Best suited for island style modular kitchens where the chimney hangs down from the wall, directly above the cooking range.

Built-in chimney

It may either be a wall-mounted chimney or an island style chimney, which is built into the interior of the kitchen, hiding the body and ducting pipes of the chimney system completely.
