# How much Electricity does a Cooker Hood use?

Contents

Do you know how much electricity a cooker hood uses? Well, let’s find out! Ideally, you should aim to use the most energy-efficient appliances at home. This blog post will help you calculate how much electricity your cooker hood uses so that you can get a general idea of what it is.

The power consumption of a standard cooker hood can start from around 60 watts up to 250 watts or so. Typically, the more powerful the cooker hood (higher extraction rate e.g.), the higher the power consumption.

## What is the average cost of an hour of electricity?

The average price of an hour of power for a family in the UK, at the time of writing, is around £0.31.8p per kilowatt-hour (kWh), though this will depend on your electricity provider and the type of applications you use.

### What is a kilowatt-hour (kWh)?

You may have heard of watts, as well as kilowatts, which is simply 1000 watts.

A kWh is a measure of how much electricity you’d use if you used one kilowatt for an hour, similarly, a Wh is a watt-hour – but most electricity providers charge based on kWh. You can think of it as being the same as if you’d have one 1000 Watt cooker hood (that’s a crazily high-powered cooker hood!) switched on for an hour.

## How much electricity does a cooker hood use in an hour?

In order to work out how much electricity a cooker hood uses in an hour, we simply need to divide the wattage of a cooker hood by one thousand. For example, if we take the Klarstein Cooker Hood, it has a wattage of 190 – which is fairly average for a cooker hood.

In order to calculate how much electricity this cooker hood uses we need to do the following:

190 / 1000 = 0.19 kWh

## How much does it cost to use a cooker hood for an hour?

Continuing with our example, now that we have the kWh of the Klarstein hood, we now need to multiply the cost of an hour of electricity – which as mentioned above, is approximately £0.32p.

0.19 kWh x £0.32p = £0.0608p

Therefore, running a cooker hood for one hour would cost approximately £0.608p.

## Are cooker hoods expensive to run?

As we can see by the calculation above, it is quite inexpensive to run a cooker hood for just an hour – but this figure can add up over time. Although it is affected by many factors, this is something to consider when choosing a cooker hood for your kitchen.

## What factors affect the cost to run a cooker hood?

There are a number of factors that can make the cost to run a cooker hood fluctuate quite a bit.

The amount of electricity a cooker hood uses depends on:

1. The power consumed by the motor
2. The number and type of speeds available on your cooker hood (it is more efficient to change speeds than to turn a big motor on/off)
3. The room’s volume
4. How long you run your hood for
5. The efficiency of the cooker hood

## How to keep running costs low?

As discussed earlier, while the cost to run a cooker hood is quite low, it can add up over time.

Here are some steps to keep your electricity bill costs low:

1. To save money on your electricity bill, you can adjust the hood’s speed depending upon how high an extraction you need.
2. It is also important to ensure that the extraction rate of a cooker hood is not too high for a room or it may have a negative impact on temperature.
3. Cooker Hoods should not be run for more than two hours at one time, i.e. when cooking, preparing food, after your shower or bath etc.
4. For typical residential applications in a kitchen, for example, you shouldn’t ever need to keep it permanently running.
