A cooktop, commonly called a kitchen chimney, is an important appliance that helps ventilate the kitchen of fumes, heat, and smoke. It keeps the kitchen fresh and clean while maintaining the air quality. The height of the stove should be one of the most important considerations when establishing a kitchen chimney. The ideal Kitchen chimney height from stove should be at least 24 inches.

The correct kitchen chimney installation height ensures the chimney’s efficient functioning and prevents smoke and odors from entering the kitchen. To enable efficient suction of smoke, fumes, etc., always place the stove against the outer wall of your kitchen.

The ideal kitchen chimney height from the electric stove and the factors to consider when choosing the height is discussed in this article.

Importance of Chimney Height Calculation

Space of Your Kitchen

When calculating the optimal height, one of the most important factors to consider is the space of your kitchen. The reason for this is that the height will directly impact the amount of heat and smoke that can escape from your kitchen. If your chimney is too short, the heat and smoke will be trapped in your kitchen. They will eventually cause problems with your ventilation system. On the other hand, if it is too tall, the draft from your kitchen will be much more robust and could cause your food to overcook.

Suction Capacity

When calculating the suction power, height plays a vital role. The taller the chimney, the more suction capacity it will need and the higher the air pressure will be at the bottom of the chimney. The higher the air pressure, the more suction power the chimney will have. The suction power is calculated in cubic meters per hour. The chimney’s suction capacity is suggested to be at least ten times greater than your kitchen’s volume.

There are a few things to remember when calculating a chimney’s suction capacity:
The height should be measured from the bottom to the top of the chimney.
The larger the diameter of the chimney, the more suction power it will have.
The temperature of the air inside the chimney should be considered.
The hotter the air inside the chimney, the more suction power it will have.

Ductless or duct chimneys?

There is no easy answer when choosing between ductless and ducted range hoods. Both have pros and cons, and the best option for your home depends on various factors. To help you make a decision, here is a closer look at the critical differences between ductless and ducted range hoods:

Ductless range hoods are less expensive and straightforward to install than ducted range hoods. They also don’t require any ductwork, which can be a significant plus if your home doesn’t have existing ductwork or if you’re uncomfortable with cutting into your walls or ceiling to install ductwork.

On the downside, ductless range hoods are ineffective at removing smoke and foul smell from your kitchen. They also recirculate air back into your kitchen, which can cause the air to become stale and can contribute to indoor air pollution.

Ducted range hoods are more expensive and difficult to install than ductless ones. However, they are much more effective at removing smoke and odors from your kitchen. They also don’t recirculate air back into your kitchen, so the air stays fresh and clean.

Why is Determining the Right Height Important?

Determining the correct height for your kitchen chimney from the stove is essential for several reasons. Firstly, the effectiveness depends on the distance between the stove and the chimney. If it is too close to the stove, it may not be able to capture all the smoke and fumes, leading to poor air quality in the kitchen. On the other hand, if it is too high, it may not be able to capture smoke and fumes effectively, resulting in poor ventilation. In addition, determining the correct height ensures the safety of the kitchen. If the chimney is too low, it may pose a fire danger, especially if you have a gas stove.

Factors to Consider When Determining Kitchen Chimney Height from Stove

Several factors come into play when determining the ideal kitchen chimney height from the cooking surface. 

Type of cooktop

The type of stove you have in your kitchen plays an important role in determining the standard height of the chimney. The chimney should be at least 24 inches above the cooktop if you have a gas range. If you have an electric stove or induction stove, the chimney can be lower since it does not generate as much heat as a gas stove. You should use a chimney width of 60 centimeters or greater if the stove has 3-4 burners.

Kitchen Size

A lower height may be appropriate if you have a small kitchen. However, if you have a big kitchen, you may need a higher chimney to ensure adequate airflow.

Hood Dimensions

The size of the hood also determines the optimal chimney height. A small hood may require a lower chimney height, while a bigger one may require a taller one.

Duct Length

A longer chimney duct may require a taller chimney to ensure sufficient airflow. The chimney duct should have a 6-inch diameter circular cut in its external wall.

Hire a Professional

If you’re not sure about the minimum height of the chimney, hire a professional to assist you. A professional will take into account all the factors and ensure that the chimney is installed at the right height.

Follow the Manufacturer’s Guidelines

Always notice the maker’s guidelines when installing the chimney. The manufacturer’s recommendations consider the hood’s size, type of stove, and other factors, ensuring that the chimney’s efficiency is greatly increased.

How to Measure the Distance Between Stove and kitchen hood

For identifying the best kitchen chimney height from the stove, you need to measure the distance between the stove and the chimney. Here’s how to do it:

  • Measure the distance between the kitchen platform and the ceiling.
  • Reduce the height of the cover from the ceiling height. Reduce an additional 3 inches for gas ranges and 1.5 inches for electric stoves.
  • The result is the ideal height of the chimney from the stove.

Common Mistakes to Avoid When Determining Kitchen Chimney Height from Stove

Here are some typical mistakes to avoid when determining the kitchen chimney height from the stove:

  • Installing the chimney too low can pose a fire hazard, especially if you have a gas stove. Always guarantee the chimney is at least 24 inches above the gas stove.
  • Installing the chimney too high diminishes its efficiency, resulting in poor ventilation. Always ensure the chimney is installed at the minimum height for maximum efficiency.
  • Ignoring the manufacturer’s recommendations can lead to poor chimney efficiency, reducing its lifespan. Always observe the manufacturer’s recommendations when installing the chimney.

Ideal Height of Kitchen Chimney from Gas Stove

As mentioned earlier, the best possible height of the kitchen chimney from the gas stove is at least 24 inches. This height assures that the chimney captures all the smoke and fumes, preventing them from escaping into the kitchen. The 24-30 inches height also ensures the safety of the kitchen, as it reduces the chance of an accidental fire.

Conclusion:

Determining the ideal kitchen chimney height from the stove is important for the chimney’s efficient functioning and the kitchen’s safety. Factors such as stove type, kitchen size, hood size, Kitchen design, duct length, etc. play a crucial role in determining the ideal height. Always follow the manufacturer’s recommendations and consider hiring a professional if you still need to determine the ideal height. Also, if you already have an exhaust fan in the kitchen, your chimney may not be required. Avoid common mistakes such as installing the chimney too low or too high and ignoring the manufacturer’s recommendations.
