How To Decide Suction Power Of Chimney | Size Of Kitchen Chimney

Cooking involves frying and roasting herbs and vegetables that generate unwanted smoke and fumes, along with an oily and greasy substance. If not expelled out, these greasy substances get settled on the walls and other interiors of the house, giving an untidy look. With the help of the suction power of chimney in your kitchen over the cooktop, you can easily get rid of all these unwanted and unnecessary pollutants.

To understand how to decide the size and suction power of your kitchen chimney, let’s first look at the various components of the kitchen chimney and their role.

Components of Kitchen Chimney

The main components of kitchen chimneys are a suction motor, filters, and vents.

The suction capacity of the chimney motor pulls in the smoke, gases, and oil particles that get filtered through the filters. The greasy particles get stuck in the filters, and the smoke gets thrown out through the vent. This ability makes the chimney a must-have kitchen appliance, especially for the modern open kitchen that lacks windows and doors to expel out the smoke.

But, only having a chimney installed in the kitchen is insufficient; what is more important; is having the chimney with the right size and suction capacity to take out the smoke efficiently.

While buying a chimney for our kitchen we normally take care of the brand, looks, and price. But the size and suction power of the chimney are two major features that you need to take care of.

So if you are unaware of how to decide the size and suction power of the chimney, here is a guide to help.

How to Decide the Size of Kitchen Chimney

Kitchen chimneys are available in the market in two standard dimensions, which are 60 cm and 90 cms wide. Out of these two, you should choose a chimney based on the size of your stove, cooktop, and kitchen.

The thumb rule for selecting the right kitchen chimney size should be slightly greater than the stove or hob size. When the Kitchen chimney size is smaller than stove or hob size than some part of cooking fumes, smoke is an escape from kitchen chimney suction power and spread in the kitchen, failing the very purpose of spending and installing the chimney in the kitchen.

So, if you have 2 to 4 burners stove or hob, you can select 60 cm kitchen chimney size. However, if you have 5 burners, it is wise to choose a 90 cm size one.

This way, you can have the right chimney size for your kitchen.

How to Decide the Suction Power of Chimney

After the size, the most important thing is to have the right suction capacity of the kitchen chimney. The suction motor of the chimney comes in various capacities. Generally, chimneys have suction capacities from 400 m³/hr (cubic meter/hour) to 1,600 m³/hr.

From these variable capacities, which one is the best for your kitchen.

So to decide the suction capacity of the chimney there are two things that you need to do. First, calculate the suction capacity of the chimney that you need. Secondly, consider the other factors that impact the suction power of the chimney.

Calculate the Suction Capacity of Chimney

The right suction capacity of chimney should be the one that can suck out at least ten times the volume of air in the kitchen in one hour. In other words, the suction capacity of the kitchen chimney is calculated by multiplying the length, width, and height of your kitchen by ten.

For example, if your kitchen is 3 meters wide, 4 meters long, and 2.5 meters high, that means your kitchen volume is 3x4x2.5=30 meter cube. So, it would help if you buy a kitchen chimney with a suction capacity of at least 30×10=300M cube per hour.

Now suppose, if the dimension for your kitchen is different, and you have a volume of the 75-meter cube, you should buy the chimney with a suction capacity of at least 750-meter cube per hour.

Other Factors Affecting the Suction Power of Chimney

Various other factors play roles in the suction of the air, such as the duct, length, diameter, and the number of bends it includes.

Duct Length

It is said that the long size ducting requires more effort to suck out smoke air; therefore, more suction power is needed. Small diameter ducting becomes an obstacle to throwing out smoke. So, it is advisable to have a small length ducting with a large diameter.

Cooking Habit

Apart from the duct length, another important factor is the cooking habit that includes how often do you cook? What do you cook? What all ingredients do you use? Whether you cook fried and carbohydrate-rich food that requires a lot of heat and generates a lot of smoke, or you cook food that requires less heat and does not release in smoke and greasy components.

Suppose you cook healthy, low-oil food, and there is not much smoke then, a chimney with a suction capacity between 700 and 1,000 m3/hr should be effective for your kitchen.
However, if you regularly make deep-fried foods, and there is a lot of heating, and in the process, a lot of smoke gets generated, it is better to opt for a chimney with more suction power, such as 1200, m3/hr. Or above. The chimney won’t be efficient with a lower suction capacity as the smoke will remain inside your kitchen and house.
For the Indian kitchen, based on the cooking and kitchen set-up, the standard suction power of chimneys ranges from 400M3 per hour and goes up to 1250M3 per hour.

Conclusion

The chimney is the heart of the kitchen. It is one of the necessities for keeping your kitchen fresh. This can be achieved only with the right size and suction power of chimney.
Having said that, this is extremely important to install the chimney with the right size and suction capacity. The multiple factors to be taken into consideration to decide the size and capacity of the kitchen chimney have been explained in this article. Consider your cooking habit and kitchen size and set-up. They play a major role in deciding the amount of work the chimney has to do in your kitchen.

We hope that our article will help you in making the right decision.
