Kitchen Chimney Size & Suction Power

A chimney can be helpful if you have an open kitchen. A kitchen chimney can effectively suck all the fumes and expel them out of your house. However, a chimney can work effectively only if you have the right size and power.

Suction power and chimney size are the two things that matter the most while buying a kitchen chimney. It’s because a smaller one won’t be able to suck all the fumes. And a larger one may not fit in the first place. If you want to know what suction power is good and what size of a chimney is perfect, read this article in full.

Kitchen Chimney and Suction Power?

A kitchen chimney is an electric appliance that uses suction power to suck all the fumes from your kitchen. It prevents the fumes from letting in your bedroom or other areas.

Suction power is the power or capacity of a chimney to suck odor or other particles. It is usually measured in cubic meter cube per hour.

Kitchen Chimney Size Based on Gas Burners

Here’s a simple rule you need to keep in mind while buying a chimney. Always make sure the chimney is 2-3 inches wider than your gas stove or cooktop. Bigger won’t be a problem, but the one smaller can be ineffective.

Usually, there are two common chimney sizes: –

  • 90 cm
  • 60 cm

For a typical Indian kitchen, a 60cm chimney works just fine. However, if you have an exceptionally large stove, you can go for a 90 cm chimney.

The gap between Chimney and Gas stove

You need to make sure that there’s enough space between the chimney and the gas stove. It’s necessary to maintain the efficiency of the entire system. If the chimney is too far, the fumes might disperse before being sucked up by the chimney.

Keeping it too close is not a good idea either. If you install the chimney too close to the gas stove, there are chances of your chimney catching fire. So, you can keep the gap somewhere between 65-75cm.

Kitchen Chimney suction Power

As you know, kitchen chimney suction power is the motor’s capacity to suck odor or fumes. It measured in m3 per hour. More is the suction power, better is the chimney. The one with a long hose usually has more power.

Factors that affect chimney suction power

Here are some factors that’ll help you determine what capacity you need: –

Size of the duct

The size of the chimney duct can affect the chimney’s suction power. If the ducting is quite long, your chimney will have to be more powerful. Otherwise, it won’t be effective.

Number of bends

You must prefer ductwork with fewer bends. It’s because more bends will require the chimney to be more powerful. Otherwise, the chimney won’t be able to throw the fumes out.

Cooking habits

If you’re a vegan and cook vegetarian food, there’ll be less smoke. So, you won’t need much power. And if you’re a nonvegetarian, your chimney needs to be more powerful. It’s because non-veg food produces more odor and fumes.

Mount Type

The size of your chimney also depends on the mount type you choose. There are two types: –

Wall Mounted: As the name tells, this chimney is mounted on the sidewall beside which the gas stove rests. This type of mounting is most commonly found in Indian homes.

Ceiling Mounted: Such chimneys hang right on the ceiling. They are suited well for commercial or large kitchens.

Chimney suction power calculation

The right suction power of your chimney depends on the size of your kitchen. Your chimney fills your kitchen with fresh air ten times in an hour. So, you need to first calculate the volume of your kitchen and then multiply it by 10.

Now for this, you first need the volume of your kitchen. So, you need to know the dimensions, i.e., length, breadth, and height. Once you do, multiply the l*b*h. And once you get the result, you have to multiply it by 10. This way, you can calculate the suction power.

Let’s say your kitchen has the following dimensions:

L = 4m, B = 4m, H = 4m

So, the volume will be 4*4*4 = 64m3.

Now multiply the volume with 10

Suction Power = 64*10 = 640m3/h

So, your kitchen requires a chimney with at least 640m3/h of suction power.

Tips to Improve Chimney Suction Power

  • Buy a chimney with a wider hose. Wider the hose better is the suction power.
  • If you have a cassette filter, use a baffle filter instead. It is more efficient. Also, the oil and other sticky substances never affect its efficiency.
  • Clean your chimney regularly to prevent any unforeseen event and maintain efficiency.

Disadvantages of high suction power chimney

  • Too Much NoiseA chimney with high suction power will produce more noise. However, this problem has a solution. You can go for a split kitchen chimney. In a split kitchen chimney, the motor is installed outside the house. So, you won’t hear much sound inside the kitchen.
  • Power consumption: A high suction power is caused because of a strong and large motor. And this increases the power consumption. In such cases, you can go for a good chimney brand or use it wisely to save on the energy bills.

Conclusion

By now, you would have known how important chimney size and suction power is. If you don’t buy the right size or the one with the right suction power, you’ll have to struggle. So, make sure to go through the detailed info listed above.

Also, make sure to check the calculation part to find the right size. This way, you can get a more effective and efficient chimney. If the above insights proved to be helpful, please share them with others as well. We’ll be posting similar informational content soon. So, keep coming back for more.
