Hood height over gas and electric stove or panel

Sanitary regulations and technical documentation for equipment dictate that the minimum distance between the gas stove and the hood should be 65 cm. This is the standard set by the manufacturer. The maximum distance between the gas stove and the cabinet with built-in ventilation is 85 cm, although this recommendation can be extended by using more powerful equipment to ensure complete air purification.

For electric burners without an open flame, the minimum distance between the hood and the stove is 5 cm less. The method of filtration (recirculation or vented) does not affect the established norms for the bottom horizontal distance.

Built-in horizontal models should be installed at the same distance as wall-mounted and suspended models: at least 60 cm from electric stoves and 65 cm from gas stoves.

It is necessary to take into account

In order to accurately determine the distance between the cooktop and the air intake, several factors need to be considered:

• Power of the cooktop
• Type of equipment
• Orientation of the air intake plane – inclined or horizontal
• Type of stove
• Height of the cook

The distance at which the kitchen air filter should be installed above the stove depends on the power of the hood. For low-power models of the recirculating type, the minimum allowable distance should be maintained. These models are suitable for kitchens up to 10 m².

Fireplace hoods can be elevated above the recommended standards. These particular models boast a generous air intake area, exceptional performance, and power. Equipped with 4 fans, they effectively draw in air, pass it through filters, and expel it through the exhaust duct. Consequently, such hoods ensure a thorough purification of the kitchen and dining area combined. With their ability to extract not only the soot, grease, and steam above the stove, but also the entire room air, they contribute to the efficient removal of airborne contaminants.

On the other hand, recirculation units are designed to filter and reclaim air, delivering it back to the kitchen in a purified state. These units are especially suitable for small spaces where introducing fresh air from outside is challenging. They effectively remove mechanical impurities and water, leaving only carbon dioxide behind. However, due to the recirculation process, the oxygen levels in the air remain low.

Prior to selecting the air filter model, one should factor in the dimensions of the kitchen. Additionally, it is imperative to accurately determine its placement.

The distance between the ventilation equipment and the stove is a crucial consideration. The unit’s capacity is determined by the air volume within the room where it is installed.

Hood installation height standards

Distance from hood to cooktop

The distance between the cooking surface and the hood is determined by the type of cooking equipment and the specific location of the ventilation unit.

In addition, the design features of the appliance, the size of the air outlet, or the presence of additional elements on the panel do not affect this measurement. The only exception may occur if the height of the ceiling in the room prevents following all the recommendations.

First and foremost, it is important to consider the recommended height specified by the manufacturer, adjusting it within a range of 10 cm higher or lower.

Installation height of the stove hood above the gas stove

The ideal distance from the cooktop to the ventilation system is determined by manufacturers and experts in the field. The guidelines for installing a ventilation system are based on practical knowledge, so it is important to follow them in order to enhance the efficiency and safety of the device.

In order to determine the appropriate height for hanging the hood over a gas stove, it is advisable to refer to the established standards:

• For inclined systems, the recommended position of the hood above the stove is 0.55-0.65 m;
• For other models, the preferred height is 0.75-0.85 m.

The standard height for an extractor hood above a gas stove differs from the corresponding measurements for other types of countertops. This is due to the specific characteristics of a gas stove – if the hood is too low, it may accumulate soot.

There is a minuscule possibility of causing fire to the oil smudges that have accumulated on the surface of the equipment.

Installation height of the hood over an induction or electric cooker.

Redefining the initial text while maintaining its HTML markup:

In this case, the process is much simpler as the induction stove doesn’t require an open fire, allowing for a smaller distance to install the hood. The height at which the hood should be installed above an electric stove can vary:

• 0.35-0.45 m for angled models;
• 0.65-0.75 m for other ventilation systems.

When installing the ventilation system, it’s important to consider the user’s convenience – the distance can be adjusted to their specific needs.

Mounting height of inclined models

Inclined hoods offer convenience in their use:

1. They are ideal for individuals who are tall as they will not be obstructive while cooking.
2. They are also suitable for small spaces as their slanted design visually occupies less area, creating the illusion of increased space.

Another benefit of this design is that it does not protrude beyond the work surface, giving it a sleek and non-bulky appearance.

Features of installation of other types of hoods

Comparison of the distance between various hood models and the stove

In addition to incline hoods, users frequently utilize the following types:

Built-in systems – installed directly into the cabinet. These models have a shallow depth and a retractable component.

T-shaped and dome structures have only a visual difference. Dome ventilation systems are suitable for spacious rooms, but may be too voluminous for small kitchens. Another term used for these hoods is "fireplace hoods," which is commonly used by marketers to promote their products. These hoods often do not clean the air, but rather pump out the exhaust air.

Flat hoods are the smallest and most compact systems. They take up minimal space and can be attached directly under the kitchen cabinet, making them ideal for small kitchens. The top devices in this category feature a retractable panel that increases the intake of exhaust air, making their operation more efficient without taking up extra space.

Island hoods are installed in large rooms where the stove is located away from the wall.

No matter which model is chosen, it is crucial to adhere to the standards mentioned above when it comes to the distance above the cooking surface. This ensures the proper functionality and maximum efficiency of the system.

Power calculation

To calculate the airflow capacity of kitchen hoods, you can use the following formula: L x W x H x 10 (or 12) = capacity in m3/h. Where:

• L represents the length of the kitchen;
• W represents the width;
• H represents the height;
• 10 or 12 is the coefficient used for the calculation.

Here’s an example to demonstrate the calculation of the hood’s capacity: L x W x H x 10 = 4.5 x 3 x 2.7 x 10 = 364.5 m3/h. This means that the hood will be able to process 364.5 cubic meters of air per hour.

However, it is important to note that the coefficients 10 and 12 are used to find the maximum capacity and do not account for any power reserve. In emergency situations, the hood’s capacity may not be sufficient. Additionally, the calculation coefficients may vary depending on the type of stove being used:

• For gas stoves, the number can increase to 20 (due to the increased flow of gas combustion products, compared to an electric cooking surface, over which only vapors from the food being cooked appear).
• Over an electric hob, the number can reach up to 15.

So, for a kitchen with a gas stove, the capacity value would be: L x B x H x 10 = 4.5 x 3 x 2.7 x 15 = 546.75 m3/h. It is recommended to have a small power reserve in addition to the calculated capacity when the fans are operating at maximum load.

If there is no door and instead an arch is installed, or if the room is connected to the living room (dining room), then it is necessary to adjust the calculated data to account for these characteristics. To quickly determine the capacity, you can refer to the table.

General requirements, rules and standards for hood installation

When installing any exhaust systems, it is important to follow certain general rules. The most crucial aspect is to adhere to the requirements of the manufacturer and the established standards. The instructions for each model typically provide recommendations on the ideal distance from the stove. Generally, these parameters can be adjusted within a range of 10 cm, depending on the height of the user or the peculiarities of the furniture structure. These standards have been developed to prevent fires and ensure compliance with fire safety regulations. It is also essential for the width of the hood to match the width of the cooktop. If the suction surface is smaller than the cooktop area, efficient air purification will not be achieved.

Installation details and height above the gas hob

Gas stoves have the most stringent requirements when it comes to the installation and placement of the hood. It is imperative to adhere to the standard recommendations, as failing to do so poses a significant risk to both individual families and all occupants of the building.

Firstly, it is important to note that gas stoves involve the use of open flames. Therefore, any objects or structures placed above them must be positioned at least 75-85 cm away from the surface.

When installing the ducting, one must bear in mind that completely obstructing the ventilation opening is unacceptable. It should be possible for gas that has accumulated in the room due to an accident or mishandling of the stove to escape freely. If there is no separate outlet to the ventilation box, it is necessary to divide the existing one into two sections. This can be accomplished by installing a specialized grille that is divided into two compartments. One part of the grille has a hole for the pipe, while the second part has standard dividers.

Installation features and height above electric and induction hobs

The guidelines for installing a hood above electric and induction stoves are a bit more flexible. Specifically, when it comes to the suggested height above the stove, it is permissible to position the device slightly lower – approximately 65-75 cm away.

Features of installation and height of the inclined hood

In miniature rooms, where the priority is to maximize available space, inclined hoods play a critical role. When it comes to installing a tilt hood over a gas stove, the requirements are slightly adjusted. The bottom edge of the surface should be positioned 55-65 cm away from the gas stove. On the other hand, only 35-45 cm of distance is needed for an induction or electric stove.

Hood installation height over electric and induction hobs

When installing the hood above an electric or induction stove, it is possible to slightly lower the height, as these types of stoves are considered safer to use compared to gas stoves. Furthermore, the distance can be adjusted based on the specific design of the appliance. For instance, island hoods are installed on the ceiling; angular hoods are placed in the corner; dome and fireplace hoods are mounted on the wall; built-in hoods can be installed inside a hanging cabinet; flat hoods are attached to the back panel of the wall. The installation height for an inclined hood is different from the rest, as it can be mounted above an electric or induction stove at a height ranging from 35 to 45 cm.

Installing a Hood above an Electric Cooker

For compact kitchens, professionals and designers suggest the installation of built-in or slimline models. Apart from the convenience factor, slimline units are also considered to be budget-friendly options. By selecting a device with the appropriate power output, you can effectively eliminate unwanted kitchen odors throughout your entire apartment.

Homemade hood from drywall

Special attention should be devoted to the DIY construction using plasterboard sheets. In this particular scenario, there is no requirement to purchase relatively costly components. Additionally, the manufacturer’s hood itself is associated with a steep price tag.

Another benefit of these designs is their potential to be stylish, unique, and seamlessly blend with the interior.

Materials and tools

To begin with, it is important to create an outline and perform measurements of the area in order to procure the appropriate amount of plasterboard. This entails taking accurate measurements of the designated location for the hood installation, sketching it out, and subsequently creating a detailed blueprint on paper.

The width of the DIY construction is the same as or slightly larger than the corresponding measurement of the stove. The height is determined structurally, depending on the placement of the kitchen ventilation duct and the overall design solution.

The surface area is calculated by adding up the dimensions of each side. It’s recommended to purchase slightly more material than the calculated amount. In addition, self-tapping screws and metal profiles will be needed.

Furthermore, putty and primer should be purchased for surface finishing.

The following tools will be required for the job:

1. Perforator.
2. Screwdriver.
3. Measuring tape.
4. Level.
5. Utility knife.
6. Trowel.
7. Roller.

Step-by-step instructions for making a drywall hood

When all the necessary preparations have been completed, you can proceed directly to the next steps:

1. Using a pencil, mark the positions on the wall where the profiles will be fixed, based on the provided sketch. Ensure that the standard height of the hood above the stove is taken into account.
2. Next, install and secure the main (starter) profile on the wall (and if required, on the ceiling) by drilling holes and using strong dowels or anchors.
3. Afterwards, attach the vertical elements to the main profile using self-tapping screws.
4. Lastly, attach the starter profile and cross bars at the bottom. This will complete the formation of the frame for the duct box.
5. First, create the cone shape for the hood. Attach the profiles that form the strengthening ribs to the bottom of the box frame. Secure them horizontally at the bottom, following the dimensions outlined in the sketch. Self-tapping screws should be used for this purpose.
6. If desired, you can install a fan for forced air extraction at this stage. However, even without a fan, the structure will effectively collect air currents from the slab.
7. Divide the drywall into pieces of the required size and screw them onto the frame.
8. All seams should be carefully filled with putty.
9. Apply a layer of primer to the finished hood.

This product allows for natural ventilation of vapors from the stove.

Finally, add a decorative finish to the hood.

Making the body from different materials

Aside from plasterboard, alternative materials such as plywood or plastic panels can be used for constructing the hood. The choice ultimately depends on the skill and capabilities of the owner.

Plywood, in particular, is easier to attach to the profiles, does not crumble or soil one’s hands, and does not require priming or puttying. Additionally, it can be easily wallpapered for the finishing touch.

However, the profiles used for the plywood need to be stronger. It’s recommended to use metal angles with a steel thickness of 1.5 – 2 mm, or even stainless steel. The process of constructing the hood body remains the same as when using plasterboard.

Decorative finishing of the hood

The decorative coating of the plasterboard surface can vary.

Typically, after priming, a water-based emulsion paint is applied in the color of the kitchen set or wall. Additionally, foam plastic moldings or skirting boards, and sometimes decorative wooden elements, are added to the construction.

It is also possible to wallpaper or even tile the surface with ceramic tiles. Plasterboard is such a versatile material that it can be treated externally in any way.

Recommendations for use

To ensure the durability of the exhaust system, proper maintenance is essential. The following guidelines are provided by manufacturers:

Regularly clean the grease trap filter, which can be easily removed by releasing the spring lock. You may clean it in a dishwasher or simply under running water and soap. It is also recommended to change the charcoal filters every 2-3 months. Ensure that you check their condition only when the system is switched off.

Exercise caution when using the hood in rooms where both a gas stove and a fireplace are being operated simultaneously. The ventilation system may extract the air necessary to support combustion. In such cases, it is advisable to provide additional ventilation for the room.

Remember to avoid touching the lamp immediately after it has finished operating to prevent burns.

Furthermore, it is crucial to maintain proper ventilation in the room during operation. For safety reasons, keep in mind not to touch the lamp when it is no longer in use.

To disconnect the appliance from the power source, make sure your hands are dry. It is important not to yank the cord.

Conducting measurements and calculations

As can be observed, considering all factors and making an accurate calculation can be quite challenging. However, it is important to avoid regretting the purchase of a device that cannot fulfill its intended tasks.

Manufacturers have developed certain criteria:

• A ventilation system with a capacity ranging from 200 to 300 cubic meters per hour is suitable for individuals who cook infrequently or have a small-sized kitchen. In other words, it is sufficient for the continuous use of 1-2 burners.
• For families consisting of 3-4 people, or kitchens of medium size, as well as those using 2-3 burners on a daily basis, a hood with a capacity ranging from 300 to 400 cubic meters per hour is recommended.
• A large kitchen and a large family can benefit from an air cleaning device with a capacity of 500-600 cubic meters per hour. This kind of hood is essential for daily use of the stove and all its burners (5-6 in total).

For approximate measurements, special tables or manufacturers’ data can be used.

To quickly estimate the performance, take into account the kitchen’s area and ceiling height. Multiply these values by the stove coefficient.

If the kitchen has unique dimensions or is smaller than 40 cubic meters, calculate the value by multiplying the kitchen’s length, width, and ceiling height. Then, multiply the result by 10 or 12.

The coefficients of 10 or 12 remain constant according to health regulations. These numbers indicate that the air should be purified every 5 minutes, or 10-12 times per hour. As a result, the ventilation system’s capacity must exceed the kitchen’s volume by at least 10 to 12 times.

At times, this coefficient may need to be increased based on the frequency of usage and the type of stove being used. For instance, for a gas stove with large burners that are used daily, this number could reach 20. Whereas, for an electric stove, a coefficient of 15 is appropriate.

If a non-standard stove is being used regularly, it is recommended to consider additional coefficients for the floor, stove, and smokers when determining the system’s capacity. However, it is not necessary to purchase a system with excessive reserve capacity.

For instance, let’s consider a scenario where the kitchen is 2 meters long and 3 meters wide, with ceiling heights of 2.5 meters.

Consequently, the estimated capacity would be: 2 * 3 * 2.5 * 10 = 150 cubic meters per hour.

This value can then be multiplied by the factor of 1.3, which complies with the sanitary standards.

In case someone smokes inside the kitchen, an additional 15% is added to the productivity for each smoker present.

The aforementioned data is applicable for enclosed spaces. However, if the kitchen lacks a door and is partitioned from other rooms by a hallway, an extra 30% of the aforementioned capacity should be accounted for.

Another important parameter is the height of the chef.

It is crucial to ensure that the hood does not come into contact with the head and does not hinder access to the back burners or the placement of large pans.

As such, it is advisable to take measurements and simulate the cooking process before purchasing and installing a hood. To prevent measurement errors, keep in mind that a sloping hood should be measured from its lowest point to the burners.

For all straight hoods (such as dome or built-in hoods), the measurement should be taken from the filters to the surface of the stove.

Inclined hoods are particularly recommended for electronic, halogen, and induction stoves. They occupy minimal space and effectively purify the air.

You should also take into account the size of the hood. Determine how far it will extend over the cooking surface, how easy it will be to cook and replace charcoal and grease filters, as well as to clean the stove and access the back burners.

All of the distance factors mentioned above should be balanced. Otherwise, there is a risk that the hood will not perform its duties effectively. Even the most powerful device, installed too high, will not be able to effectively remove all impurities from the air. On the other hand, if an extractor hood is installed too low, soot can accumulate on its lower side and possibly ignite.

Choosing the correct installation height will prolong the lifespan of the cooker hood, allowing it to operate at full capacity with minimal effort. In the worst-case scenario, the appliance may not be able to fulfill its functions or may even burn out.

Calculating the minimum required extractor hood capacity

Before purchasing a new air purifying device for the kitchen, it is important to conduct measurements and calculations in order to determine the appropriate capacity that will effectively clean the air in this specific area.

Prior to buying a range hood for your kitchen, it is crucial to accurately assess the volume of air in the room that requires ventilation. You can then proceed to perform the necessary calculations on your own or consult with a seller using these measurements to determine the required equipment performance. The minimum power needed can be determined by the following formula:

Pb = Vk × 12 × 1.3 = (a × b × h) × 12 × 1.3

• Vk = (a × b × h) represents the volume of the kitchen;
• The air in the kitchen must be entirely replaced 12 times per hour;
• The first coefficient, 1,3, represents the actual power factor taking into account power losses from airflow through vents, filters, and pipe bends;
• Pb refers to the calculated power of the hood.

All the necessary measurements and power calculations can be performed independently. Simply measure the length, width, and height of the kitchen using a tape measure, recording the figures in meters. Then, use a basic calculator to make the calculations. Multiply the three numbers together to obtain the volume in cubic meters (m3). Multiplying this by the other coefficients will give you the capacity in m3/hour.

The model’s performance may not always align precisely with the calculations. In such cases, it is advisable to opt for the nearest higher value. While a less powerful device may come at a lower cost, it would continuously operate at maximum capacity, potentially leading to quicker wear and tear. Additionally, there is a chance that complete air purification may not be achieved, allowing odors to permeate into the surrounding rooms.

Ventilated equipment typically has a high capacity and can be installed above the electric stove, even if it is larger than the standard size. This powerful exhaust ventilation system ensures a thorough cleaning of not only the kitchen, but also the living rooms, removing steam and grease.

By utilizing an exhaust hood that expels air outside, ventilation effectively removes moisture, carbon dioxide, and unpleasant odors from the apartment. However, it is important to note that in order for exhaust ventilation to work properly, it is necessary to have an intake of fresh air from the outside into the apartment.

It is crucial to consider the proper distance between the stove and the ventilation system. Above a gas stove, it is not advisable to install powerful equipment and hang it too close to the heating elements. This is because a nearby opening with a high air flow can extinguish the burner’s fire.

Height from the stove to the sloping and horizontal hoods

To determine the distance for hood installation from the stove, it is important to first understand the different types of hoods, as this is a key factor in calculating the appropriate distance.

When it comes to the mode of operation, there are three main types, each with its own unique features:

1. Recirculation hoods: These hoods use fans to suck in air, which is then passed through carbon and grease filters before being released back into the kitchen as fresh air.
2. Flow-through hoods: These hoods draw in exhaust air, which is then filtered through a grease trap and expelled outside the house through ventilation ducts.
3. Combined hoods: These hoods offer a versatile option, allowing the user to switch between different modes using the control panel.

In terms of their shape, hoods are available in various varieties, including:

• Built-in (installed inside a cabinet or other object)
• Island (used in large kitchens)
• Suspended (a flat hood that is installed above the stove)
• Retractable (a type of hood that can be hidden when not in use)

An important criterion for choosing a hood is the shape of the air inlet. There are two main varieties:

1. Inclined
2. Horizontal

When determining the height of the hood installation above the stove, it’s important to consider the size and shape of each type of hood. Manufacturers typically recommend specific height indicators for proper installation above the cooking surface.

Here are some common recommendations:

Manufacturers of hoods recommend specific heights for the placement of hoods above stoves. The recommended heights are as follows:

• For a horizontal hood, it is best to place it at a distance of 80 cm;
• If you have an inclined cooker hood, it is best to place it at a distance of 60 cm;
• If you have a straight hood above an electric stove, the recommended distance is 70 cm, while for an inclined hood, it is 50 cm.

It is important to note that these recommendations are based on an average kitchen height and may vary depending on individual preferences and comfort levels while cooking.

Inclined hoods

So, what is the ideal height for hanging inclined-type hoods? The unique design of these hoods speaks for itself: the air is sucked in by fans located in the upper part of the unit. As a result, the equipment should be installed lower than horizontal-type hoods.

The manufacturer recommends hanging the extractor above the stove at a distance of 60 cm. This distance provides optimal performance and ensures that the hood does not obstruct the cook during use.

The inclined design of the hood is very convenient as it provides the user with more flexibility in removing the filter for cleaning or replacement.

Furthermore, inclined hoods come with a low probability of fire incidents. Fires typically ascend vertically, resulting in minimal contact with the appliance.

If you opt for an inclined recessed hood, it is crucial to consider the distance between the stove and the kitchen wall where it will be installed. Therefore, it is advisable to pre-plan the kitchen layout to ensure seamless completion.

Horizontal appliances

What is the measurement between the range hood and the stove? The measurement of the horizontally installed hood above the cooking surface varies from the previous example. Manufacturers specify in the device’s technical documentation an indication of 80 cm.

Nevertheless, numerous models vary in their functionality. For instance, a less powerful exhaust hood should be positioned lower to effectively handle the flow of expelled air.

Furthermore, it is crucial to consider the height of the ceilings because if you install the range hood too close to the ceiling, there will be insufficient space to connect the housing with the elements of the ventilation system, which is essential for the proper functioning of flow-based equipment. Additionally, it is not necessary to strictly adhere to the size specifications if the individual’s height exceeds the average measurements.

Cooking should be a pleasurable experience accompanied by comfort. This is why it is important to accurately calculate the most suitable height.

When choosing island hoods, it is advisable to assume responsibility. It is crucial to calculate the distance before making a purchase, as this will help avoid a situation where the dimensions of the device do not align with the optimal gap between the hood and the stove, be it gas or electric.
