Can I use a recirculation-only extractor hood in my new kitchen?
Building Regulations do require extraction in extensions and new build kitchens to deal with condensation. Existing kitchen re-fits, which do not require the involvement of Building Regulations, will not be affected by this rule. It must be remembered, however, that extraction does not need to rely on an extractor hood over the cooker or hob. A separate extractor can be installed on the wall or ceiling and should be able to remove 60lt/min. This means that you can choose a recirculation-only extractor hood if you wish, as long as you have your installer include a separate extractor.
All types of extractor hoods only need to be able to remove 30lt/min, if placed over a cooker or hob. All the BEST hoods exceed this extraction rate.
Ducting out your hood is a more effective way to extract fumes, vapours and odours from your kitchen.
Ducting is the pipe work used to take the extracted air away from the hood to the outside of the house. You can get more information about ducting formations here which will explain how to structure ducting and bends. The general rule is, to ensure the greatest efficiency use the shortest lengths of ducting with the fewest number of bends. It is also wise to use rigid smooth pipes rather than flexible ribbed pipes which can slow down the airflow.
If you are still unsure, talk to your installer, or call the Britannia technical department on 0844 463 9705 (Option 1), who will be happy to help.
An external motor is when the motor is separate from the actual cooker hood and is housed in a metal box which can be sited outside the house, for instance on an exterior wall or roof. Only certain BEST hoods have the option of an external or remote motor.
An external or remote motor must be ducted out.
A remote motor is similar to an external motor in that the motor is separate from the cooker hood and again housed in a metal box, but instead of the motor being sited outside the house, it is placed inside the house in another room, cupboard or roof space.
If you want a remote or external motor you need to request this at the outset as there is a separate code for this type of hood. The hood will be supplied without a standard motor, and a remote or external motor needs to be ordered separately. There are different codes for the remote and external motors, so you need to decide whether you want the motor inside or outside the house. This will depend on the type of property; what sort of space is available; how far away the motor would be in either option. Your installer would be able to help you with this decision.
Ducting is extra and ducting pipes and bends must be ordered to connect between the hood and the motor in the case of an external motor, and between the hood, the motor and the outside in the case of a remote motor.
There is no maximum or minimum recommended. The principles are the same for any ducted hood – the shortest pipe length with the fewest bends possible will be more efficient than very long pipe work with lots of bends.
Can two motors be used, i.e. the motor included with the hood and then an additional remote or external motor. Would this improve efficiency?
No this is not possible with the BEST range of hoods and would not improve efficiency.
No, both motors need to be ducted out.
The standard motor can be fitted on either side of the hood. This gives flexibility when installing.
Ensure first of all, that you order the correct code for the downdraft and also order the external motor separately. The standard motor will not be supplied; therefore, you will receive the hood itself and the metal box housing the controls. This means more space will be created where the hood is to be sited. You will also need to order ducting to connect the external motor to the hood.
This tends to be pre-determined by the size of the hob and downdraft and the space available on the work top. There are no recommended distances.
The Enigma and Cirrus hoods can be used at standard UK ceiling height of approx 2.3 metres. The further away the hood is from the hob, the less effective it becomes. For higher ceilings, a false ceiling is recommended to lower the fitted height of the hood.
There are 6 LED lights which are fitted down the central panel of the hood.
No, the ducting is fitted at the top of the hood, therefore, a chimney kit or cupboard is required to obscure the pipes. Chimney kits are an optional extra.
The Electronic Soft Touch controls are situated at the side of the hood. The printed symbols on the front of the glass indicate where to locate each button. These printed symbols are not touch controls. The Electronic Soft Touch controls at the side of the hood need to be pressed to switch the hood on or off, to operate the speed levels and timer functions.
For operation of the hood we recommend a gap of at least 50mm between the hood and a wall cupboard. This allows enough space to access the controls which are located at the right hand side of the hood.
