How to Calculate Correct Kitchen Chimney Size?

Every kitchen has a chimney, and it is essential for various reasons, including ventilation and cleaning. Almost everyone knows the value of having a kitchen chimney installed. The majority of people, however, are unaware that the proper installation of a kitchen chimney and understanding the optimal kitchen chimney height are both equally essential considerations. It not only boosts efficiency but also overall safety by eliminating hazards.

Specific considerations, including the optimum height, suction capacity, and stove type, must be considered while establishing a fireplace or chimney. We will discuss all about kitchen chimney height and suction capacity calculation, including how to calculate the size of your chimney.

  • The optimum height of the kitchen chimney about the stove is what you want to achieve.
  • Installation of a kitchen chimney at a height and distance from the stove
  • During the installation of a kitchen chimney, it is essential to establish the right optimum size for effective and efficient working of appliance. It is important to note that there should be appropriate space between the cooking surface and the chimney hood.
  • A too-close distance may cause result in the chimney hood catching fire. It is hazardous. On the other hand, the exhaust rate is reduced if the distance between the two points is too great. The chimney would also draw in the fresh air, defeating the point of having one in the first place. It will become hard to choose an optimum height that does not compromise either safety or the intended function.
  • The fitting or installation’s height typically vary between 21 and 30 inches, depending on the kind of gas stove being installed.
  • Gas stove with a range of 24 to 30 inches in diameter
  • Electric stove with an oven of 21 to 30 inches in diameter
  • The optimum height of the kitchen chimney installation is influenced by various variables, including the stove type, kitchen design, and chimney size, among others.

It is advised that you read the chimney manual guide for more detailed instructions or contact a professional to install the chimney correctly for the best results.

 

Things to consider for choosing the size of Kitchen Chimney

There are many things to consider when determining the height of a kitchen chimney installation. When choosing the size of a kitchen chimney installation, take into consideration the following factors.

 

Types of stoves

Types of stoves

As previously stated, the height of the kitchen chimney varies depending on the kind of stove. For example, the optimum size for an electric or induction stove varies from 21 to 30 inches. While the ideal height for a gas stove goes from 24 to 30 inches, depending on the model.

 

Height of the chimney

It is preferable to have a chimney that is the same size or slightly larger than the cooktop to suck up smoke readily, and the chimney may be placed at a somewhat safe height above the stove. For example, a chimney width of 60 cm is ideal for a furnace with 2–4 gas burners.

 

The distance between the stove/cooktop and the chimney

When constructing a kitchen chimney, this distance, which should be between 24 and 30 inches in ideal circumstances, should always be considered.

If the distance is less than 24 inches, it may result in the chimney hood catching fire. If the height is more than 31 inches, it will reduce the exhaust rate. In each of these instances, the chimney will be completely ineffective. Therefore, the proper height of the kitchen chimney is critical for the efficient operation of the appliance.

 

The ductwork in the chimney

Always go for a duct that is no more than 12 feet in length to save money. A longer duct leads to more bends, each of which acts as an obstacle for the gases to pass through. To prevent this, many individuals choose a lower installation level, which is dangerous once again. Use a compact duct with little twists and turns.

 

Capacity for suction

The ability of the chimney to draw in the air also plays an important part. Specially in choosing the height of the chimney. It is recommended that the chimney be placed below 30 inches from the cooking surface if the chimney’s suction capacity is insufficient to suck away the fumes efficiently. Always ensure that the chimney is installed following the suction capability.

 

What is the height of the kitchen chimney, both at its lowest and highest point?

Even though the significance of an appropriate height for a kitchen chimney is frequently neglected in kitchen design and construction, it is one of the most important factors to consider.

Kitchen chimneys are typically 21 inches in height, with a minimum of 21 inches. If the size is smaller than this, it may cause a great deal of difficulty while cooking. It is also dangerous since the chimney will be very near the cooking surface, and it can catch on fire.

Even experts would suggest that you utilize the same height since it has been determined by safety studies to prevent any mishaps in the kitchen.

For efficient suction, the maximum height should be 31 inches above the ground. Unless the elevation is higher than this, the advantages of the chimney will not be available. It will not be able to remove the fumes from the atmosphere appropriately. It will result in poor ventilation, odor, and an increase in the accumulation of oil.

 

Is the height of the kitchen chimney different in an Indian kitchen?

No, not at all. No matter where you live, the minimum and maximum distances needed for chimney installation are the same. You should, however, keep a few key considerations in mind.

The use of large amounts of spices and oil in Indian cuisine is well-established. It necessitates a great deal of frying, which results in Indian kitchens that are oily and sticky. As a result, the construction of a kitchen chimney in an Indian kitchen should be tailored to the cooking habits of the Indian population.

First and foremost, in an Indian kitchen, one should use a baffle filter or a carbon filter chimney. These filters are exceptionally efficient in removing oil and grease particles from the air.

Second, an Indian kitchen should be equipped with a chimney with a more excellent air suction capability, which typically ranges between 400 and 1000 m3/hr, depending on the size of the cooking space.

 

Conclusion

According to what you’ve learned so far, suction capacity is critical in establishing the optimal height for a kitchen chimney installation. Chimneys with a greater suction capacity may be erected with relative ease up to 30 inches in height. Remember, large suction capacity chimneys generate a lot of noise and use more electricity than their smaller counterparts.
