Electric kitchen chimneys are a relatively new kitchen appliance and not may people know about its working. Understanding how this chimney works can get a little technical, but we have simplified it for you. To understand how chimney works in kitchen, let’s learn first about the major parts of the appliance. Here is how kitchen chimney works.


  • The chimney can be divided into two parts – An exhaust hood that sits right above your gas and the air column, which connects the hood to the external surroundings.
  • Now, all the work is mainly done in the hood itself. It contains a trap mesh that captures the smoke and steam generated while cooking. Once the entire gas and steam are caught, they are pushed forward to the filter.
  • Every chimney comes with a primary filter that is made from a different material. However, in ductless chimneys, you will find an extra carbon mesh.
  • As per kitchen chimney working, the filter traps the oil molecules, greasy particles, and smoke.
  • There is a rotating motor fan inside the exhaust, sitting right before starting the air duct. This fan pushes out the air into the duct, forcing it to travel higher up the column for ventilation. This is how kitchen chimney works.

1. Removes extra heat from the kitchen 

Whenever you are cooking in a closed space, where there is little or no ventilation, the heat from the gas makes the entire kitchen warm. The resultant temperature is far more than the standard room temperature, making your time in the kitchen more taxing. But, if you have a chimney, the overall heat temperatures will be much lower in comparison.


2. Keeps the kitchen walls and ceiling clean 

Cooking means using oil, butter, and other sorts of greasy elements. When you heat these items, the vapors that rise from your cooking pots usually are laden with oil and grease molecules. With no escape route, the vapors rise above, cool down, and form greasy layers on the walls and ceiling. Once you install a kitchen chimney, you will see that the device will help prevent accumulation of grease on kitchen surfaces.


3. Removes smoke and soot from the kitchen air

After understanding how kitchen chimney works, you can easily guess that one of the main benefits of this device is that it removes smoke and soot. This is a big benefit if you have an open kitchen.
