What type of cooker hood is best for you? There are two types of cooker hood: extraction and recirculating. Extractor hoods or fans are far and away the most effective type because they suck all steam and fats straight off the hob and eject it outside your home.
Just like extraction rates, most cooker hoods also come with a noise rating that's measured in decibels. The majority of cooker hoods are rated at around 60-70 decibels (dB). If you plan to cook while entertaining or socialising, you may want to invest in a quieter cooker hood with a lower dB rating.
Angled cooker hoods feature perimeter extraction, which ensures more effective cleaning of the air in your kitchen. This extraction method forces the air around the edges of the panel to increase the air pressure and speed. The result is much stronger extraction to eliminate even the most stubborn odours from the air.
The safe bet is to go with a hood that is 900 CFM or higher for your gas range. The larger the range, the more CFM you'll need. If you own a range against a wall, install a wall hood, under cabinet hood, or range hood insert. For a range on a kitchen island, buy an island hood.
If you want to create a designer look in your kitchen, angled cooker hoods can be a great option with their sleek, geometric shape. Angled cooker hoods are also perfect for smaller kitchens, and the sloping design is perfect for accessing your cooking space and keeping an eye on your pots and pans while you cook.
Cooker hoods or a venting hob is not any legal requirement. But, your kitchen should always be ventilated by any window or venting duct. To remove the grease particles in a limited space, a ducting kitchen fitter is essential.
Vented extraction fans or hoods are very common in kitchens across the UK. These extract the stale and moisture-filled air out of your kitchen through ducting in the wall. So, these do require a hole to be drilled in the wall.
Carbon filters in the extractor hood absorb dirt, grease and odours from the air when the cooker hood sucks in the cooker air before it is returned into the room. Recirculating hoods can be installed almost anywhere in a kitchen because they don't need to be connected to an external wall.
Plug and Socket: You can install a new socket that can be hidden in the chimney section of the cooker hood. This socket can be spurred off of an existing circuit via a junction box. You can then use a plug with a 3amp fuse and plug in your cooker hood like you would any normal appliance.
Not all cooker hoods operate at the same speed and power or produce the same level of noise. Some high-performing ones can be very noisy. It's important to choose the right hood if you don't want to be disturbed by the noise.
If the noises only occur at the highest setting, the problem is usually caused by an increased back pressure in the suction system. The ducting hose is either too long, or its diameter is too small, or there are many bends. Check the installation and use smooth pipes, if possible, to resolve the problem.
The rule of thumb is simple: the hood should be 1.5 times wider than the stove area to ensure efficient removal of hot air and cooking smells.
Ideally, you want to select a range hood that is at least as wide as your cooktop, though you should also have at least three extra inches on each side. Most residential kitchens do well with range hoods that fall in the 30- to 36-inch range.
Unvented range hoods do filter some grease and cooking odors from the air, but the general consensus is that they're nowhere near as effective. Nor do they remove heat and humidity, so they won't help keep your kitchen cool while you cook.
Choose a hood that is two sizes up from your stovetop, extending six to 12 inches on each side. For example, if you have a 48” range, a 60” outdoor hood is ideal. Remember, bigger is better when it comes to the coverage area of your range hood for a gas cooktop.
Fans can be mounted on rubber washers to help reduce vibration where a cooker hood is mounted on the wall, and changing the duct design to include less bends and cross-sections may help reduce noise, as well as using rigid duct and increasing duct size to reduce air resistance.
Stop vent clanging with dampers
Measure the diameter of the vent pipe and order the dampers from a duct supply company (hvacquick.com is one source). Start by replacing the backdraft damper directly above the vent hood. If that doesn't solve the problem, install a second damper near the wall or roof discharge cap.
If your range hood came with a three-pronged plug, it does not need to be hard-wired. Just plug the hood into a wall outlet and use an extension cord if necessary. If it did not come with a three-pronged plug or it came with a cut plug, the hood needs to be hardwired.
"Yes an electrician would be able to do the whole job for you. Cooker Hood prices vary but should not take longer than 3/4 of a day. For a neat job lifting of floorboards above the hood would be better. Electricians day rates are all different depending on area.
The socket should feed the fused connection unit, which will also act as an isolator for the cooker hood. This is then connected to the cooker hood. You don't need the additional fan isolator.
Your cooker hood should ideally be either equal to or bigger than the width of the hob. If your hob measures up to 750mm wide, a cooker hood width of 900mm is advised.
