How Ducted Chimney Works? 

A ducted chimney comprises of oil channel, a fan or a blower, PVC pipe, and a vent. It works by sucking in hot air or smoke via the exhaust fan. The oil channels catch all the oil particles and then its passes through the fan. The pipes connect them to a duct, which transports airborne particles from the kitchen to the outside. A filter collects the solid molecules that result in an unhealthy environment, and rather than releasing the refined air; it throws them out through a well-designed duct system. They are the most common and basic type of chimney.

What is Ductless Chimney?

A kitchen chimney without duct or ductless chimney’s pipes works by sucking in hot air or smoke via the exhaust fan. Its primary function is to improve the quality of the air inside the kitchen, so it only removes smoke and exhaust fumes. Unlike, ducted chimneys ductless chimney do not require large pipes to remove smoke so they do not require specific for installation in the kitchen.

However, ductless chimney consume more power so they consume more electricity. The only drawback of ductless chimney is that it does not filter out warmth and dampness from the air which eventually leads to more buildup in kitchen.

How Ductless Chimney Works? 

Ductless chimneys are simplistic chimneys that capture smoke, water vapour, and toxic pollutants into the air and release the fresh, refined air back into the air. Ductless chimney consists of oil channel, carbon duct and a fan or a blower. The air is loaded with smoke and oil is attracted by the oil channels where all the particles are collected. The oil and smoke particles are filtered out, however, it does not remove the warmth air from the kitchen and this leads to buildup in the kitchen. There are various filters like charcoal/baffle/cassette filtration system in the range hood that would draw up smoke, odour, and heat. These filtration systems will remove odors, absorb the heat, and smoke before being released back into the room.

1. Size and Performance

The installation of a ducted chimney takes up a lot of space. The ducts must be connected via pipes for the appliance to work properly. The pipe efficiently removes all of the smoke and heat from the kitchen. It absorbs all of the fumes and expels them outside the house.

Meanwhile, a ductless chimney necessitates the bare minimum of setup. Other than the unit itself, they don’t have any extra parts. They have a large exhaust fan to remove all smoke and contaminated air and cleanse the air inside the kitchen.

2. Working

A ducted chimney is capable of removing all moisture and odours from the kitchen by sucking out the air. Furthermore, it dissipates all of the heat, significantly lowering the kitchen temperature. This entire system will keep your kitchen dry, odour-free, and fresh.

On the other hand, ductless chimneys can effectively filter out all dirt particles from the air but cannot remove humidity from the air if the kitchen is not adequately ventilated. Not only that, but the appliance is unable to lower the kitchen’s temperature. 

3. Installation

The ducted kitchen chimney is difficult to install. It can be time-consuming and labour-intensive. The procedure will necessitate the assistance of a professional, and it will also be costly because the duct must be laid out.

On the other hand, the ductless ones do not require any major installation and can be placed wherever you want. It only needs to be bolted to the wall and plugged into a power outlet.

4. Heat and Noise Emittance

A ducted chimney is far more useful to remove hot air from the kitchen. It works by completely removing the hot air outside the house, making your kitchen cooler. Furthermore, a ducted chimney is silent in operation. This is because the fans do not have to operate as hard to move the dirty air outside.

On the other hand, the ductless chimney simply recirculates the air after it has been filtered. As a result, it does not eliminate the heat and humidity in the kitchen. It also makes quite a bit of noise. To get the air through the filters on ductless chimneys, the exhaust fans must spin extremely fast, resulting in a lot of noise.

5. Efficiency

Ducted chimneys provide a path for contaminated air to exit the kitchen while providing a comfortable and pleasant ambiance. As a result, ducted chimneys are more comfortable and preferred in terms of kitchen experience.

On the other hand, ductless chimneys absorb heated air, purify it by removing solid molecules, filtering them, and releasing them in the kitchen. As a result, it makes little or no difference to the odour and the unpleasant scene it creates.

6. Suction Power

A ducted chimney has a maximum air suction capacity. It sucks out all of the kitchen’s exhaust fumes while maintaining a comfortable environment inside.

A ductless chimney comes with a high suction capacity. It removes all of the smoke and contaminated air and replaces it with fresh air.

7. Maintenance

The operation of the duct-ranging hoods guarantees the immediate release of all particles. As a result, the appliance is simple to maintain. You must clean and replace the filters regularly to improve their performance.

The ductless chimney, on the other hand, does not expel air. You must clean and replace the filters regularly to improve their performance. As a result, unlike ducted chimneys, the oil collector and filters must be replaced more frequently.

Final verdict

So there you have it: a detailed analysis of duct and ductless chimneys. With these points in mind, you should be able to determine which type of kitchen chimney is best for you. Your kitchen chimney, duct vs ductless chimneys, are both performing the same function. 

It is up to you to decide whether you need a duct or a ductless chimney; what is best depends on your needs. You can make a decision based on your cooking frequency and needs. However, if you eat Indian food regularly, it’s more advised to install a ducted chimney for your kitchen.
