How to choose a hood over a gas stove: what criteria to consider when choosing a suitable model

What to look for when buying a kitchen hood?

Preparation for the purchase of a kitchen hood (umbrella) begins with the study of the main characteristics:

1. Type - direct-flow (flow-through) or recirculation (circulation). The first type is equipped with a metal grease filter.Thanks to the detail, grease does not linger on the engine and body. The second version of the devices is usually equipped with two filters: to remove oil particles and eliminate unpleasant odors.
2. Power - the volume of air that can clean the kitchen umbrella depends on this indicator.
3. Noise - the noise level is quite difficult to determine in a store. Please note that the standard noise figure is 50 dB. The characteristic can be compared with a quiet conversation of people at a distance of three meters.
4. Dimensions - determined depending on the size of the plate. Ideally, the hood should match the width and length of the hob. In any case, you should not buy a unit of smaller dimensions.

It is also advisable to pay attention to the method of installation of cleaning systems. They are suspended, dome or fireplace, wall, island, corner

The most modern are retractable kitchen umbrellas that are built into the countertop. The most innovative appliances are mounted directly on the hob.

About the classical formula for calculating the power of the hood

The power indicators of the hood directly depend on its performance. The more it is able to pump air, the more powerful the fan is in it, which needs an electric motor to work.

For equipment connected to ventilation ducts, operating only in exhaust mode, the performance should be calculated based on the cross section of the air ducts. It is almost impossible to do this without engineering knowledge and a housing project. And the calculation of the exhaust power by area is suitable only for recirculation models. Unlike the first option, the size of the ventilation ducts does not affect their performance.

The classic calculation of the performance of a kitchen hood is the multiplication of the square of the kitchen, its height and a factor of 12. However, the resulting figure is very conditional. It doesn't take into account many factors.

This formula allows you to calculate the parameters for ideal conditions:

• cooking on an electric stove;
• kitchen room with closed doors and windows;
• rectangular kitchen without an abundance of decorative delights.

If a gas stove is used for cooking, then the coefficient 12 should be changed to 20 without hesitation. In this case, in addition to fumes, the hood will also have to remove gas combustion products from the kitchen. Plus, in any case, it is worth adding 15-20% in reserve.

Another 25-30% of the power must be added to the carbon filter. It creates additional resistance for the passage of air flow.

If the door to the kitchen is constantly open or there is an arch instead, then the parameters of the exhaust technology should be calculated based on the total quadrature of the adjacent room. The same applies to corridors, as well as combined living rooms or halls. The absence of barriers increases the volume of processed air, as it constantly circulates between the kitchen and adjacent rooms.

Approximate indicators of the required performance of the hood in the kitchen

In most private and apartment buildings ventilation ducts in section do not exceed 125 mm, which allows pumping about 400 m3/h of air through them. If you install a hood of greater productivity in the kitchen, then there will be little sense from it. In addition, air ducts often have irregularities, narrowing and turns inside, which further reduces their throughput.

If you follow a simplified calculation, then for a small kitchen, a low-power hood will suffice.However, formulas are formulas, and common sense never hurts. Smells from the stove fill a small room faster, and their concentration in this case is an order of magnitude higher than in a spacious kitchen. For a very small room where food is prepared, it is necessary to select equipment that is more powerful than the calculated indicators.

Classical formula: kitchen length × kitchen width × ceiling height × 10-12 (coefficient) = desired hood performance.

Important Adjustments

1. Thus, without leaving a reserve of power for emergency situations - the hood works constantly in the most noisy mode.

1. For electric models of cooking surfaces, the coefficient can be 15, for gas ones - 20 (after all, in addition to fumes from cooking, there are results of burning gas streams). So, for a kitchen 4 x3 meters with a ceiling height of 2.7 meters - the calculation of the power of the kitchen hood will be the following performance indicators: 486 m3 h and 648 m3 h, respectively - for an electric and gas stove. For comfortable use, we recommend an extractor hood at medium speed with a performance margin of 600-800 m3 per hour.

In general, this knowledge is quite enough to choose the right hood according to the parameters. Everyone can apply the formula, let's say, "with their own hands."

Interesting moments

However, it will be useful to dispel some myths that have somehow developed both among sellers of kitchen hoods and among buyers:

There is an opinion that for a small-sized kitchen of 6-8 m2, a primitive, most ordinary hood is quite enough.Based on the parameters, this is indeed the case, but, based on logic, we see the following: in a small room, odors spread much faster, and the concentration of combustion products is also higher. It is known that the amount of these secretions does not depend on the size of the room.

There is a misconception that the kitchen hood is designed to provide complete ventilation, and even under any conditions. However, this is not entirely true - the efficiency of the hood depends directly on the type of installation and on the organization of the air supply.

Types of hoods and their photos in the interior

A properly selected extractor hood in the interior of the kitchen works perfectly at the highest temperatures and protects against hot fumes, greasy condensate, excessive humidity, and overheating.

Classic range hood

Classic is a good choice for everyone who loves traditional solutions and simple technical devices. You can place the unit above the stove, put it in a closet, decorate it. This option is straight and angular. But a corner hood for your kitchen is a specific option that is less common.

Outwardly, the classic evokes nostalgia - it is good to take it for an antique, retro kitchen, for a traditional interior, colonial or country, Provence.

At the same time, the corner version looks unusual and saves space. And this is also quite a classic solution, because its main principle is visibility and fit into the interior.

Mounted hoods are fixed on the wall, often have retractable panels - this helps to significantly expand the coverage area. They can be island type, which is convenient if the stove is located at a distance from the wall.

Built-in hood

Usually kitchens with a built-in hood photo are distinguished by a harmonious appearance, because the built-in appliances are hidden from prying eyes. Inside a niche in a cabinet or bedside table, you can mount a built-in model of an exhaust device.

The built-in version is easily mounted inside the furniture - in a niche or in a cabinet, cabinet. The sliding panel provides mobility and usefulness of the device. Periodic washing of filters is required, which cannot be removed or replaced.

Dome hood

The hood-dome resembles a fireplace in its shape

For the operation of such a device, it is important to have a ventilation system with a connection to the duct

But nowadays the quality of technology has increased significantly, and the popularity of dome hoods has also increased. Many are not satisfied with the large size, but due to the scale, high efficiency was achieved.

The design of models is also progressing, today you can choose any design and type of material. Traditionally, systems are made of metal alloys and plastic. But there are glass domes, made of natural wood.

Retractable hood

This version of ventilation is convenient in a small apartment, studio or small space. Ergonomics is ensured by the mobility of the working panel.

Filtration at two levels ensures the natural circulation of air masses, while the device operates at a standard speed when the air passes through the shafts without changing the temperature. Sensors signal dirty filters and help clean the system in time.

Most often it is a flat shape, which allows you to leave free space on top. Complex structures of pipes and bends are not required.

island hood

This type of device, like an island, is distinguished by the possibility of mounting on the ceiling directly above the stove, regardless of location. A good island hood in a modern kitchen simply and inexpensively solves the issue of air filtration and saves space.

How to choose the right hood

The quality of the hood depends on its performance. Hoods, which are chosen wisely and meet all requirements, provide six or ten times the change of air in the kitchen. Space plays a big role in performance. I would also like to note the fact that the best kitchen hoods also have powerful fans that operate at 2 or 4 speeds.

When choosing a hood for the kitchen, it is important to consider not only its performance, but also the absence of noise during operation. About how to choose a hood so that it does not interfere with your life, below.

The choice of kitchen hoods depends on many factors.

1. If the device creates noise similar in sound level to a whisper, then do not hesitate to select it (measured up to 35 decibels).
2. The model is quiet if the noise emanating from it is similar to a conversation at a distance of 10 meters (up to 45 decibels).
3. A device comparable to a conversation 3 meters away from you (50 decibels) will not cause much noise. This is the normal noise level.
4. It is not advisable to purchase hoods with a noise level above 50 decibels. You will feel her presence throughout the apartment.

When the loudness of the work is over, it's time to take a closer look at what the device you are interested in is made of. Here you need to know all the subtleties and varieties. Materials from which the device can be made:

• plastic;
• aluminum;
• stainless steel;
• tempered glass;
• enamelled steel.

The most popular is the aluminum hood, thanks to its price-quality ratio and attractive matte finish. Aluminum is distinguished by the fact that it is easy to clean and does not get dirty with fingerprints. The most stylish type of hood is a device made of "stainless steel". However, if none of the materials attracted your attention, there are models made individually from other materials.

If the points described above do not cause doubt in you, then it's time to move on to the next selection criterion. Let's try to answer the question of how to choose a hood for the kitchen, depending on the type of control. It happens:

• touch - you only need to touch your finger and select a task;
• push-button - standard and familiar control, where each button corresponds to a mode;
• slider - you are provided with a mechanical slider that fulfills your requirements and settings.

What volume should the hood have? The device will be considered correctly selected when it is similar to the dimensions of the stove or completely equal to them. But, if you are lovers of miniature household appliances, then a small model corresponding to the size of the stove is unlikely to suit you. In this case, the amount of extraction should be clearly larger.

The hood will not harm the design of the kitchen, but, on the contrary, will add some charm to it

Choosing a hood for the kitchen, which one do you prefer - with or without an air duct?

There are two main modes of operation of equipment in the kitchen. They are:

1. The air that has been absorbed by the hood is vented to the outside.
2. Air flow recirculation. That is, the air is sucked in by the equipment, undergoes cleaning measures and returns to the kitchen.

The first principle of operation is much simpler and easier. The hood has an anti-return principle.It sucks in dirty air and blows it out. This happens by connecting the equipment to the ventilation in the kitchen. In such devices there are special filters that can protect against dirt and grease from getting inside. This method is called coarse cleaning. The strengths of such a hood are:

• relatively low cost;
• no need to change filters too often;
• does not create a lot of noise;
• strong enough air absorption, which allows you to quickly eliminate unpleasant odors.

They also have one significant drawback - the kitchen must be equipped with an air duct.

Hoods that have a recirculation system can quickly make the air in the room clean and fresh. This happens due to the filters installed in them. That is, the flows of air masses pass through the cleaning system and return again to the kitchen space. This solution becomes the only possible one where there is no chance to install an air duct outside. Typically, these types of hoods are much more expensive than other models, but they do not guarantee 100% purified air in the room. Usually fixed to show at 70%. In addition, the filters get dirty quickly, they need to be changed constantly.

The hood device can also be divided into the following mounting methods:

1. Mounted. The equipment can be flat, standard type or canopy. From the name it is already clear that the installation is carried out under a wall cabinet or directly above the stove.

2. Embedded. Usually the hoods are hidden in wall cabinets, and only a sliding panel remains outside.

3. Wall. There are such types of kitchen hood designs as domed or fireplace hoods. Installation takes place immediately to the wall above the surface of the plate.

4. Corner. The principle of fastening is the same as for wall hoods, only in a corner.

5. Inclined. The device possesses the increased functionality and simple management.

6. Island. Installation is carried out to the ceiling above the hob, if the possibility of fastening to a wall or wall cabinet is excluded. This is usually practiced in a studio apartment.

Island

Before choosing a particular model, you need to clearly know what style of the room the kitchen will have, as well as choose the right way to install household appliances.

How to choose the right hood for power?

The power of modern kitchen hoods varies from 170 to 1450 m3/h.

Typically, the area of ​​​​the room for which the equipment is suitable is indicated in the accompanying documentation, among other technical characteristics. This is convenient for the buyer, since he does not need to make calculations on his own. Similar information can also be provided by the seller in the store.

However, the performance of the kitchen hood should be selected not only depending on the area of ​​​​the room: the air can be polluted from smoking, the intensity of cooking, and other factors.

You can calculate the optimal performance of the device yourself: multiply the area of ​​the room by the height of the ceilings, then multiply the resulting value by 12. The final figure will be the performance indicator according to which the equipment should be selected.

When making calculations, one significant nuance should be taken into account: if you plan to buy a cooker hood with a filtering function, part of its power (about ten percent) will be spent on overcoming airflow resistance. To avoid performance degradation, add the indicated 10 percent to the final figure during calculation

Important! If the kitchen and living area are combined into one space, the area of ​​both rooms must be taken into account during calculations.

Rating of the most powerful kitchen hoods

The modern home appliance market offers a wide range of range hoods. The budget segment is not inferior in the range of expensive brands. The list of popular models will help you make the right choice based on the parameters of the device.

The grease filter protects the internal parts from evaporation, the carbon filter is purchased separately, it lasts for about six months.

The kitchen hood is not a tribute to fashion, but a necessity and a manifestation of care for the family. Vapors of liquids, detergents and drops of vegetable oils pollute the air of the apartment, furniture, ceiling. After cooking delicious food, you have to start cleaning. You should choose the hood for your kitchen in terms of power so that it copes with the tasks. The correct calculation of performance will make it possible to buy a quality model. In all other respects - design, color, body type and lighting, you can safely rely on your taste.

Purpose and principle of operation of the hood

How to choose a hood? Consider the principle of operation and the purpose of the hood. The hood for the kitchen, according to its principle of operation, corresponds to forced ventilation. Extraneous odors, combustion products, as well as fumes formed during the cooking / frying process are automatically removed from the air. In the kitchen, small particles of fat and unwanted odors will certainly appear.

Inside the hood there is a filtration system that can effectively capture soot, odors and all kinds of fumes. There is a separate forced ventilation system. The listed nodes are located in one building. This is how the extractor hood in the kitchen is implemented. On the top of the case is a mechanical or electronic control panel.

Given the principle of air purification, household appliances are divided into 2 classes:

Supply type devices - operate on the principle of forced intake of air masses and its subsequent removal to the outside, through an integrated ventilation system.

Modern hoods are placed above the stove on the wall or on the ceiling. If the area allows, you can hide the unit in a hanging cabinet that opens from the bottom - this is not only functional, but also aesthetic. Outwardly, it is almost impossible to notice it.

If we talk about wall and ceiling hoods, they are made in such a way as to best match the design of the kitchen.

When choosing an air purifier, you need to pay attention to several points: air purifiers that are attached to the wall look like a small visor or fireplace. Some models have a retractable screen with a filtration system inside

Dimensions

The value should be selected based on the dimensions of the hob. It depends on the width how well the evaporation generated from cooking will be captured.

The dimensions of the hood should be slightly larger than the dimensions of the panel. On the market, you can find devices with a width of 50 to 90 cm. Models with a side of 60 cm are standard and universal. They are suitable for most gas stoves and electric surfaces.

The depth depends on the parameters of the furniture in which the device is mounted. There are several solutions.

1. Narrow technique with a retractable panel that increases the coverage area.
2. The device is equal in depth to a headset.
3. Option with a depth less than that of the cabinet.

In kitchens where cooking is frequent and varied, the use of the first group of devices is more appropriate. But the second and third types are more appropriate if the cooking process occurs periodically.

If you put a copy of a smaller than necessary size, then you will face negative consequences:

• the unit will not 100% cope with its task, and some of the odors and fumes will enter the living rooms;
• greasy deposits and moisture will settle on the nearby walls, due to which the furniture may change color and swell.

Noise level

A working hood produces a certain level of noise, especially at maximum power. If you decide to choose the best hood for your kitchen, we recommend that you check the operation of the device before buying. However, one criterion must be taken into account here - this is that the noise of the device in a large store room and in a small kitchen will be different. The second nuance is the length of the duct, it is advisable to make it as short as possible, without bends and securely fasten it.

The normal, maximum noise level of a dome hood does not exceed 50 dB when the fan is operating at maximum mode. To give you an idea, this is the noise of a quiet conversation. Such a device will not cause discomfort with its work, and if the selected hood model is noisier, then it is worth considering other options for buying.

What type of hood is better to choose?

The shape of the hood can be flat or built-in.

Embedded in furniture

Built-in (otherwise they are called integrated) kitchen hoods are installed in such a way that only the lower part of the appliance remains in sight, and the air duct is hidden behind the cabinet door.

The cost, as well as the quality of built-in models, is higher than the same parameters of suspended hoods.

The built-in device will not spoil the interior of the room at all, since it will be practically invisible after installation.

When thinking about which built-in hood to choose, pay attention to the dimensions of the equipment, which should match the dimensions of your headset. The remaining parameters when choosing a built-in hood are calculated in the same way as when choosing a conventional one.

Suspended for kitchen sets

A more traditional option is suspended (flat) hoods, which have a lower cost compared to built-in models.

Typically, such devices have low performance: for kitchens with a small area, they are ideal.

You can install a flat hood in room up to 8 square meters, in rooms with a larger area, the power of the device will not be enough for high-quality air purification. Unlike built-in, suspended models affect the appearance of the room, therefore, when choosing them, it is recommended to take into account design in addition to power and cost.

Self-installation of built-in hood

The difference in the installation of a conventional and built-in hood (of any brand and with any cubic capacity) is significant: the latter are mounted in the cabinet itself, so they do not need to be mounted on the wall. The work is carried out according to the following instructions:

1. The hood is tried on to the cabinet (which is not yet hung on the wall), the places for fixing the equipment are marked.
2. The cabinet is being assembled (if necessary). Extractor is installed. The base is mounted under the duct. The wardrobe is attached to the wall.
3. An air duct is connected to the hood, the equipment is connected to the power supply network.
4. A protective box is mounted (on top of the air duct), the operation of the equipment is checked.
5. With the correct operation of the air cleaner, the doors are installed on the cabinet.

Control panel - which one to choose

Modern hoods can have three different panels. These are:

• Push-button. Simple and uncomplicated control, which any person will immediately understand.
• Touch. More modern and functional control, unlike push-button. A light touch on the panel turns on one or another command for drawing. A household appliance with such a panel will cost much more than others.
• Slider. The mechanical slider moves along the panel.

There are no right or wrong panels and the choice is always up to the buyer. After all, each person has their own preferences, tastes and financial capabilities.

What is hidden under the name "hood"?

Not everyone knows that the standard ventilation system does not fully cope with its purpose. Sometimes the amount of air pollutants is so high that more help is needed. The device will help eliminate all the consequences of combustion and any unpleasant odor. Its action occurs thanks to special filters. Choosing a kitchen hood involves knowing all the details and subtleties of the device.

To choose the right hood, you need to understand how this device functions. It eliminates all unnecessary elements thanks to the filtering system. Models are divided into several types, united by common features. Which hood is best for you?

In the flow hood, air enters with the help of external ventilation

Device differences

Hoods differ in appearance. So, there are: built-in, suspended and wall-mounted types of hoods. Which is better for you?

1. Built-in appliances are great for kitchens with a built-in stove. Choose a built-in hood for the kitchen will help you in any specialized store.
2. Suspended models are cheap and popular among buyers, also due to their ease of installation.
3. Wall hoods are popular because they work in both modes described above.

Filter functionality

Air purification occurs due to the work of special filters. Some of them are needed to remove odors, and the rest - to trap fatty particles and soot. Depending on this, filters are disposable and reusable.

1. Disposable removable filters collect oily particles, the material of the product is plastic, sintepon.
2. Reusable filters trap fatty elements, the material of the product is aluminum and steel.
3. Disposable carbon filters neutralize unpleasant odors.

Features of hoods 50 cm wide

A distinctive feature of 50 cm hoods is precisely the small width. It allows you to install the device in a small kitchen, where there is already nowhere to turn around. However, these hoods are suitable for most kitchen appliances. stoves like gas, and electrical.

There are two main modes of operation of the hoods - recirculation and air extraction. In the case of recirculation, the air is driven through the filters in the hood and returned back to the room. In this case, ventilation ducts are not used and does not leave the room air or heat.

In the case of a tap, the air is simply taken from the room and passes through the air ventilation ducts and exits to the street.Before installing the hood, you should determine whether it is possible to do this at all, and take into account that when used in tandem with a gas boiler and a column, back draft may occur, and this is dangerous for the operation of gas heaters.

The difference between exhaust and recirculation of airFor information! Most hoods have a valve that prevents warm air from leaving the room when the hood is not working.
