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.
TYPE OF COOKER HOODS
Chimney Hoods » Designed to be mounted to a wall. Canopy Hoods »Positioned directly under your kitchen cabinet. Visor Hoods »A low cost hood designed to be mounted to a wall. Integrated Hoods »Hidden behind a cabinet door & activated by opening the door.
There are many different designs and styles of kitchen range hoods, but they all fall into five main types or categories. These include wall mounted hoods, island hoods, range hood inserts, under cabinet hoods, and professional-grade hoods.
So to break it down as simple as possible – go with a Type 1 Hood for cooking equipment that can lead to grease and grease by-products, and go with a Type 2 Hood for other kitchen appliances and equipment that require removal of heat and moisture.
Type II hoods shall be installed above all appliances that produce products of combustion and do not produce grease or smoke as a result of the cooking process. For example, Type 2 hoods are used to exhaust the excess heat produced by ovens, pasta cookers and commercial dishwashers.
It's main difference is that the parts are different. So your traditional chimney cooker hood has, believe it or not, a chimney, whilst the canopy hood doesn't. This doesn't mean they can't be ducted outside, it just means that they are for the purpose of being installed into chimney breasts that are being concealed.

Range hoods are available in a variety of sizes and designs, so you'll need to choose the right hood for your kitchen. You will need to make your decision based on how your kitchen is set up and how much you cook.
According to Lawrence Berkeley National Laboratory (LBNL) the capture efficiency of standard hoods is typically in the range of 30-40% on front burners and can be as high as 90% on back burners.
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.
NeutraTEST generally recommends that you choose a hood that is 50% wider than your stove, providing there are a maximum of 80-90 cm between stove and hood. This is especially important for induction hobs, where steam etc. spreads out further. The greater the distance from worktop to hood the wider the hood needs to be.
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.
Though less effective than a ducted model, the fact that a recirculation extractor doesn't have to be connected to an external wall means that it can be installed almost anywhere in the kitchen. Many hood styles can be configured to either recirculation or ducted extraction.
Do Kitchen extractor fans need to vent outside building regulations? There were no regulations about ventilation. Since April 2006, kitchen extractor fans have been a legal requirement in the U.K. If you renovate or build a new home, it is a legal requirement. In March 2019, the new homes act came into force.
This will depend on your project circumstances. UK Building regulations state, “If you carry out any 'building work', and there is an existing extract fan (or cooker hood extracting to outside in the kitchen) you should retain or replace it. However, if there is no existing ventilation system you need not provide one.”
Type II hoods are required to be installed over cooking appliances and dishwashers that produce heat and/or steam. They are not generally required, but can be very helpful, over rice cookers, steam tables, hot dog cookers, warming ovens, and convection ovens.
Most commercial convection ovens are required to be under a Type I hood, but there are some exceptions. Some ventless convection ovens are designed with a hood built into them, eliminating the need for a commercial hood.
The most common type of fire suppression system for range hoods is a sprinkler system. Fire suppression systems are not required for residential range hoods. Most residential hoods don't have them.
Type 1 hoods are to be used with appliances that produce grease and smoke. Such as fryers, griddles and ovens. According to the International Building Code, that includes pizza ovens.
The average cost of installing a commercial hood ranges from $964 to $1,174 per square foot.
