Step 01.

You need to determine the amount of air that the cooker hood needs to extract all the fumes, steam and odours.

i.e. cubic metres per hour = m3/h.

Establish the measurement of the kitchn length x width x height.

e.g. 5 metres long (L) x 4 metres wide (W) x 2.5 metres high (H) = 50 cubic metres.

One needs at least 10 changes of air per hour.

50 cubic metres x 10 = 500 cubic metres per hour.

You have now established that your kitchen needs a cooker hood with an airflow of at least 500 cubic metres per hour = 500m3/h.

Step 02.

You now need to choose the type of cooker hood suitable for your kitchen as well as keeping the airflow in mind.

Your kitchen dealer will help you in this matter and they will tell you the type of cooker hood you need.

i.e Downdraft – Ceiling Hood – Undermount Cupboard Hood – Wall Hood – Island Hood

Your choice requires you now to decide on a cooker hood which aesthetically matches your kitchen as well as being the correct size for the hob and also the airflow to keep your kitchen free from fumes, steam and odours.

There is a wide variety of cooker hoods on the market and it is wise to choose a hood more powerful than necessary which will enable it to run at lower speed increasing the efficiency and reducing the noise.

It is also important to make sure the ducting is correctly designed and installed so that the full power of the motor in the cooker hood is maintained.

We recommend you choose rigid ducting either 150mm diameter or 220mm x 90mm with as few bends as possible.

It is also important to make sure the ducting is correctly designed and installed so that the power of the motor in the cooker hood is maintained.
