Having a kitchen chimney installed in your kitchen is not enough for a compelling performance. The height at which you place it will decide if your kitchen hood is going to benefit you or not. Yes, this is how crucial the chimney’s height is, and yet people don’t pay much attention to it. It not only enhances the chimney performance but is also vital for the overall safety of the device and the person operating it.
In our article, we have discussed the most ideal height for your chimney installation. We have also covered all the factors that play an essential role while calculating the distance between the kitchen hood and the stove. For those of you who are wondering if there are different criteria for Indian kitchens, read on to find out more about it.
What is the Appropriate Height of the Kitchen Chimney from the Stove?
If you have installed a kitchen chimney earlier, you might be familiar with the importance of calculating the height of the chimney from the cooktop before fixing it at a place. This step is essential for the overall functioning and safety of the device. If you fix it too low, there are chances that your chimney might catch fire. This can be highly unsafe.
In contrast, if you place it too high, the chimney won’t be able to exhaust the smoke and odours efficiently. Moreover, you will find that more fresh air will get sucked by the chimney, thereby defeating the original purpose. Therefore, determining the optimal distance for your chimney will help a great deal in optimising its performance and preventing accidents.
Ideally, you should install your chimney at a distance of about twenty-one to thirty inches, depending on the stove’s type. This means that if you have a gas stove, you should place the chimney at the height, ranging between twenty-four to thirty inches from the stove. Whereas for an electric stove, this distance should be about twenty-one to thirty inches.
The size of your chimney and the design of your kitchen also plays a significant role in deciding the height of your hood. Also, it is highly recommended that you read the user manual of your chimney for height specifications. These specifications vary from brand to brand. For example, Elica mentions that the chimney height from the stove should be around 27.5 to 29.5 inches. It is essential that you adhere to such specifications for the best performance.
Factors to Keep in Mind While Calculating the Height of the Chimney for Installation
Chimney height calculation may seem like a simple task, but it depends on a number of factors, which you must keep in mind before installing it. In case you don’t have the user manual or the height specifications are missing in it, you can determine your perfect chimney length by focusing on these factors. Let’s discuss all the pointers in detail.
The Type of Stove in Your Kitchen
As we have discussed above as well, the type of stove that you use in your kitchen has a significant impact on the distance between the chimney and the cooktop. For an electric stove, this distance can range anywhere between twenty-one to thirty inches. This is because an electric stove doesn’t use naked flames while cooking; therefore, chances of accidents are less.
But the same distance increases when you use a gas stove as flames can easily cause fire. For a gas stove, you must install your chimney at the height of about at least twenty-four inches, which can go up to thirty inches in case of a high suction capacity chimney. Anything lower or more than these values can cause significant harm and reduce efficiency.
Suction Capacity of Your Kitchen Chimney
As the name suggests, the suction capacity refers to the ability of your chimney’s motor to suck fumes and smoke in an hour. It is also known as the suction power of the chimney and is measured in cubic metres per hour or m3/hr. The suction capacity is usually directly related to the height at which the chimney is installed. This means that the higher the suction capacity, the higher can be the height of the chimney.
So if your chimney has a low suction capacity, it makes no sense to install it higher as the motor will not be able to suck fumes from a greater distance. But if you want to increase the distance between the chimney and the stove, you must also compensate by increasing the suction capacity. Generally, a mere 7 cm of increase in the maximum height of the chimney requires an additional increase of 150 m3/hr in its suction power to work efficiently.
Therefore, it is recommended to always pay attention to the suction capacity of your hood in order to install it at the most appropriate height.
Length of the Chimney Duct
The length of the chimney duct is another factor that affects the chimney height to a great extent. But along with the length, it is the number of bends in the duct pipe that affect the overall performance of the chimney. The more the number of bends, the lesser will be the efficiency of the chimney.
It is usually seen that people lower the length of the chimney to avoid more bends. But this practice is highly unsafe as the chimney below the appropriate length can result in fire accidents, which nobody wants. Therefore, we recommend not opting for duct pipes smaller than six feet and greater than ten feet. For an Indian kitchen, the most appropriate length of the duct pipe is about eight to ten feet, which offers the best working at an optimum height.
The Position Of the Stove in Your Kitchen
The position of the stove in your kitchen pretty much affects everything, ranging from the height of your chimney to the length of the duct pipe. Ideally, the stove should be placed near the outer walls of your kitchen for better efficiency and least obstruction. However, if it is placed near the sidewalls, instead of lowering the height, go for a chimney with higher suction power.
Is the Chimney Height Calculation Different for Indian Kitchens?
Contrary to the widespread belief, no, the highest and the lowest height specifications are not different for Indian kitchens. These are the standard specifications that are valid for every kitchen throughout the world. However, there are a few things that must be paid attention to when installing a chimney in an Indian kitchen.
Since the Indian style of cooking involves a lot of frying with all different kinds of spices, oils, herbs, etc., the Indian kitchens are slightly more greasy and filled with odours. Therefore, the chimney specifications change a bit as compared to the Western kitchens. A baffle filter along with a carbon filter works best for Indian kitchens than the filterless technology that is spreading widely. These are pretty effective in sucking all the oils and odours from your kitchen.
In the same way, the suction capacity of the chimney for an Indian kitchen must be higher, ranging between 400 m3/hr to 1000 m3/hr for regular cooking, depending on the size of your kitchen. If you have a chimney with a higher suction capacity, you can take the advantage of installing it at the maximum distance of thirty inches as well. However, these chimneys will require more power to operate and will be noiser.
Nowadays, many brands are making chimneys, keeping in mind the Indian style of cooking. Therefore, do not ignore the details and height specifications mentioned in the user manual also.
So, now that we know how important the chimney height calculation is for the proper functioning and safety of your kitchen hood, we hope that you will not ignore this step. We recommend going by the instructions given in the user manual as well in order to avoid any damage in case of an exception.
