If you have an open plan kitchen/diner, a cooker hood is your best friend. A good one will help you eliminate cooking smells before they reach the living areas of your home to bring out the best in flexible living. Luckily, the kitchen cooker hood market is vast and varied, with solutions for all budgets, styles and sizes. From unobtrusive extractor fans that simply do the job to designer appliances that add the wow factor to a contemporary open plan home, there’s no reason why you shouldn’t find a solution that scores big on style as well as substance. I spoke to Max Davies from Classic Interiors in Solihull about the importance of extraction in any kitchen design. He recommended 3 key questions that you should ask to determine the right choice of cooker hood.
Which method of extraction is best for my kitchen?
Broadly speaking, there are two types of extraction. Air that’s extracted via a cooker hood is either ducted to the outside of the building, or recirculated in the room.
Ducted hoods should be positioned near an outside wall, or use a run of ducting to reach the wall and vent outside. To achieve the best airflow, choose a rigid (not flexible) duct of 150mm diameter. This is the most efficient extraction method to remove all kitchen odours, steam, smoke and condensation. With new builds and kitchen extensions, it is a requirement that you can remove steam from the kitchen.
However, in terms of kitchen design, the position of the ducted out cooker hood may restrict your options for layout and configuration.
Recirculating hoods, on the other hand, can be sited anywhere in your kitchen since the air does not leave the building. Instead, the appliance has a grease and charcoal filter that the air passes through before being released back into the room. This type of cooker hood is quick and easy to install, and usually more cost effective to buy.
In terms of performance, recirculating hoods are not as powerful as a ducted extractor hood, and the filter will need cleaning or replacing at regular intervals. The advantage is that there is huge flexibility about where to position the fan, which is particularly handy for flats and apartments and unusual locations.
What capacity and size is recommended?
All cooker hoods have an extraction rate; choose a hood that allows for 10 air changes per hour. The recommended capacity of your cooker hood it typically calculated by taking your kitchen volume (width x length x height) and multiplying by 10 to arrive at the desired number of air changes per hour.
When it comes to choosing the physical size of your cooker hood, bear in mind that the appliance needs to be wider than your hob. If your hob measures up to 750mm in width, a cooker hood width of 900mm is recommended; for wide 900mm hobs fit a 1200mm wide cooker hood.
Take expert advice from a kitchen installer to ensure your cooker hood is fitted at exactly the right height. The recommended minimum distance is 650mm for electric hobs and 750mm for gas hobs.
Cooker hoods have decibel (dB) ratings to indicate the noise level at which they operate. While the noise level increases with the speed of extraction, more expensive extractor fans tend to run more quietly as a general rule.
Which cooker hood design should I choose?
Gone are the days when design choices were limited to either chimney hoods or integrated extractor fans. These days, there’s a huge range of different styles, designs and materials to choose from, the main ones being:
- Canopy hoods
These extractor fans are built into kitchen wall units or fitted with canopy housing, hidden from view. Suitable for both ducting out and recirculating, these traditional hoods are purely functional and don’t detract from the kitchen design.
- Ceiling hoods
A ceiling extractor is mounted to the ceiling, typically in open plan kitchen/diners. They require quite a high extraction rate because they are fitted relatively far away from the hob. Designs include eye catching feature models that can be admired in their own right.
- Wall mounted hoods
For hobs that face the wall, a wall mounted feature hood will add visual interest to the kitchen while taking up little space. Best known as pyramid shaped chimney hoods, they also come in a variety of other shapes and designs for maximum design choice.
- Island hoods
Fitted to the ceiling above the hob on a kitchen island or peninsula, island hoods can be ducted or recirculating. A wide variety of shapes and colours are available, including beautifully design and visually stunning statement pieces that add to your interiors scheme.
- Pendant hoods
Decorative pendant hoods blur the line between contemporary light fitting and extractor hood. Suspended from the ceiling either close to a wall or above a kitchen island, most are only suitable for recirculation but create a beautiful focal point for the room.
- Downdraft hoods
These super practical high-tech hoods are installed in the worktop, behind the hob, and rise up when in operation, sliding back when not in use. Suitable for ducting out and recycling, they can be fitted close to a wall or on an island.
