Kitchen chimney installation height

A chimney can be used to remove hot gases and toxic pollutants from the air in your kitchen. It can also reduce carbon monoxide levels in the kitchen when cooking. Because the air in your kitchen is kept cool and clean, bacteria and other germs are less likely to grow.

Grilling and frying foods in oil, using masalas, seasoning dishes, and other elements of Indian cooking leave a stain on your kitchen over time in the form of dirt and food stains. Well, kitchen chimneys have many benefits and there are different types of kitchen chimneys available. When it comes to purchasing kitchen chimney there are various premium brands available, there are a lot of aspects that you need to consider first.

One of them is height. Getting a chimney of the right height is not easy. There are a lot of measurements you need to take. So in this review, we will talk about points that you should consider while calculating the chimney’s height.

Why Is The Chimney Height Calculation Important?

This step is critical for the overall function and safety of the system. It’s possible that if you set it too low, your chimney will catch fire. This can be dangerous. If you place it too high, however, the chimney will not be able to exhaust the smoke and odours effectively. Moreover, you will notice that the chimney will draw in the more fresh air, negating the original purpose.

As a result, knowing the ideal height of your chimney will go a long way toward improving its function and avoiding mishaps. The height of your chimney is influenced by the size of your chimney and the design of your kitchen. It’s also a good idea to check the height specifications in your chimney’s user manual. 

What Should Be The Standard Height Of The Chimney From The Gas Stove?

When it comes to performance, the height of the kitchen chimney is important. The average height of a kitchen chimney is between 24 and 26 inches. The height of a gas burner is between 24 and 30 inches. (Chimney height: distance between the chimney and the stove) If you have any doubts regarding the kitchen chimney height estimate, consult the manual guide that came with the chimney.

Calculate the distance between the chimney and the stove when installing a chimney. It is dependent on the size of the chimney you choose for your kitchen. The usual height (25-30 inches) chimney size ranges from 60 to 80 cm, while the standard height (45-60 cm) chimney size ranges from 45 to 60 cm (18-24 inches).

Points To Consider While Calculating The Height Of The Chimney?

Points To Consider While Calculating The Height Of The Chimney

When choosing a chimney for your kitchen, you should consider numerous factors, like suction capacity (power), size, design, number of stove burners, noise level, mounting style, filter, etc. Here is the buying guide that will be helpful to you.

1. The Dimensions Of The Chimney

The number of burners on gas stoves determines the size of the kitchen chimneys. The size of the cooking area grows as the number of burners increases. There are two types of chimneys: 60 cm and 90 cm in length. A 60 cm chimney is required for a 2–4 burner stove.

If your cooktop or gas stove has 3 to 5 burners, you’ll need a chimney width of 90 cm. Some manufacturers have begun producing 75-centimetre chimneys designed exclusively for 3–4 burners for modular kitchens. So, if you don’t want to buy the wrong product by accident, you must consider the size of your kitchen when looking for the ideal chimney for it.

2. The Type of Cooktop

The type of stove you use in your kitchen greatly impacts the distance between the chimney and the cooktop. This distance can vary between twenty-one and thirty inches for an electric stove. Because an electric burner does not use naked flames when cooking, the risk of an accident is reduced.

However, when using a gas stove, the same distance is increased because flames might readily spark a fire. For a gas stove, the chimney must be installed at the height of at least twenty-four inches, with a high-suction capacity chimney requiring a height of thirty inches. Anything less or more than these figures can have serious consequences and can reduce performance.

3. Kitchen Space

The type of exhaust system you select depends on how much space you have for your chimney. From one brand to the next, the width varies. The stove should be placed near the outside wall to easily expel smoke and gases. Chimneys with long ducts are required for stoves located further from the outside.

Long ducts have lower sucking power and slower performance. When your kitchen is designed intricately, and the stove is installed against the sidewalls, the ducts will require numerous bends and turns, lowering efficiency significantly. Although it is difficult to meet all of the requirements for increased suction power, you can adapt and install a chimney to meet your demands.

4. Chimney, duct, or ductless

To correctly install the chimney, you’ll need enough space and facilities in your kitchen. Both ductless and ducted kitchen chimneys are available. There is a difference between duct and ductless chimneys. These chimneys are available in built-in, wall-mounted, and countertop configurations. A ducted chimney exhausts the kitchen’s toxic air, grease, and smoke through a PVC pipe. A ducted chimney is the best solution if your kitchen has a complicated setup.

On the other hand, ductless chimneys draw contaminated air, absorb it, and release the clean air into the kitchen. These chimneys are appropriate for any kitchen. However, because the same air is returned to the kitchen, Also, they are unable to remove moisture from the air. So these are not considered very effective.

5. Suction Capacity

The suction power of a motor refers to how much power it has and how much gas it can absorb in an hour. In cubic metres per hour, the suction power is measured. If the chimney’s suction capacity is limited, it shouldn’t be too far away from the stove. This will result in decreased performance and increased strain on the motor. So, if you’re going to place the chimney high above the stove, make sure it has a lot of suction force to get a good result.

How To Select Chimney Suction Capacity With Respect To Height

The suction capacity of your chimney’s motor relates to how many toxins and smoke it can suck in an hour. It’s also known as the chimney’s suction power, and it’s measured in cubic metres per hour (m3/hr). The suction capacity of a chimney is usually proportional to the height at which it is positioned. As a result, the bigger the suction capacity, the higher the chimney height can be.

If your chimney’s suction capacity is low, installing it higher won’t help because the motor won’t be able to suck pollutants from a wider distance. However, if you wish to increase the distance between the chimney and the stove, you must also increase the distance between the chimney and the stove.

For frequent cooking, the suction capacity of the chimney in an Indian kitchen must be higher, ranging from 400 m3/hr to 1000 m3/hr, depending on the size of the kitchen. If you have a chimney with a higher suction capacity, you can also put it at a maximum distance of thirty inches if you have one.

Conclusion

In addition to shopping for brands and types, you should pay attention to the installation of your chimney. Both a ducted and a ductless chimney have a specific ideal distance between the stove and the hood that must be maintained.

It is recommended that you read the manual thoroughly before installing the chimney. It will include information such as the chimney’s height, preferred duct length, outlet width, and suction power. Now that we understand how important the chimney height calculation is for the proper operation and safety of your kitchen hood.

FAQs

You should not put the chimney down because it will eventually result in a drafting issue if the height is set too low. This means that the chimney will not be able to generate enough pressure to allow the air to escape to the outside. As a result, before installing a kitchen chimney, you must first calculate its height.

If the chimney is too tall and above the required level, the air may chill before reaching the top of the chimney stack. This will create negative pressure inside the smokestack, pushing the smoke back to its original place.

The effectiveness of the chimney decreases as the number of bends increases and the noise level rises. The basic rule is that the duct should have no more than three bends.

Stainless steel has been shown to perform better as a duct for efficiently removing all smokey air. Stainless steels also reduce corrosion risk and don’t need to be cleaned as often as other metals. Chimneys can also be vented with aluminium or PVC pipes.

Depending on the type of gas stove, kitchen chimney heights typically range from 24 to 26 inches to 24 to 30 inches. Other considerations, such as kitchen design and chimney size, influence the appropriate height for a kitchen chimney installation.
