On this page, you will find out how many watts an electric oven draws.
More and more kitchens now use an electric oven rather than a gas one. Especially when there is a fan, it is easier to get up to temperature and maintain stable heat. Plus we are all changing habits to be more sustainable. That means avoiding fossil fuels and moving to renewable energy. One thing to consider is the power consumption of your appliance. These are high-powered machines that require plenty of electricity to cook food.
Below we will discuss and test electric oven wattage, explain how to work it out for yourself, and calculate the total electricity required.
How Many Watts is An Oven?
The average oven uses between 2300 – 5000 watts at maximum power.
The exact number depends on the size and model of your oven. For example, a small modern appliance is rated to around 2300W while larger double ovens can exceed 4000W.
The reason for this is often down to size. The larger the internal space of the equipment the more power it requires to heat up. It is also important to note that your oven won’t always draw this maximum wattage. It will only use this amount when heating up or running on high. Once upto temperatures, an oven will be in a more idle state until temperature starts to drop.
You should also know self-cleaning ovens will draw 6000W when using this function. This is because it needs to get hot enough to burn off the dirt.
How to Find Out Your Oven Wattage
There’s 3 ways you can work out the wattage of an oven.
- Check Product Specification
The quickest way is to look at the oven’s specification. The watts (W) is usually written on a sticker on the base of the appliance. If not, you can check the user manual or the manufacturer’s website for technical details. This will state the power rating and average energy use for an hour.
- Use a Wattmeter
A wattmeter is brilliant for getting a live wattage reading and tracking total energy usage of any appliance. You can simply plug it into your oven to get instant information. This might not be possible if the appliance is hardwired rather than a plug socket.
I tested my oven which gave a live reading of 2927W while heating up and 1131W when upto heat. You can also keep the wattmeter running for longer to get an average continual running watts and electricity consumption.
- Wattage Formula or Calculator
If you know the amperage and voltage of your oven you can use this to find the maximum watts. Simply use the formula Amps x Volts = Watts. Or you can head over to the ‘Watt Calculator’ to work this out.
Oven Wattage Examples
Let’s take a look at specific examples of how many watts an oven draws. Below is a collection of modern ovens with their listed power ratings.
| Oven Model | Power Rating (Watts) |
| AEG 7000 CombiQuick | 3000 |
| OGIK LBFANX16 Electric Oven | 2300 |
| CANDY FCT405N Electric Oven | 2200 |
| CSB60A Black Conventional Oven | 2380 |
| Neff N50 Compact Oven | 3350 |
| Bosch HHF113BA0B Multifunction Oven | 2400 |
| Bosch NBS533BB0B Double oven | 5300 |
| Bosch Serie 2 HHF113BR0 Oven | 2400 |
As you can see, the power ratings vary between different electric ovens. So you should take the time to check your own appliance.
How Much Electricity Does An Oven Use?
You can’t just use the maximum wattage rating of an oven to work out how much electricity it uses overall. It consumes different amounts of power based on the function. For example, it will draw high power during heating up and then be idle when up to temperature.
If you are able to attach a wattmeter you can record the kWh usage and average running watts over the course of time for accurate information.
Plus, manufacturers list the energy consumption per hour when in use. You should see a number marked in kWh. Often this is around 0.8kWh when in use. This is the amount of electricity used for 1 hour of operation. 0.8kWh is the equivalent of 800Wh. So the average running wattage of an oven is 800W.
If you use your oven for 1 hour every day you would use 0.8kWh electricity a day. That’s 24kWh a month and 288kWh a year.
That’s a rough electricity cost of $0.12 a day or $43 a year to cook your food.
Using An Oven Off-Grid
If you’re planning to use your oven in an off-grid situation like a power outage, RV, boat, or similar, the information above is important. It enables you to pick the correct power products and know how long you can run them for.
As we have seen these are very power hungry appliances so you might first consider using a toaster oven or microwave to reduce demands.
You can either use a power inverter, portable power station, or generator to produce electricity.
To make sure everything runs smoothly you should check two things on this equipment – wattage capacity and total energy capacity.
Your power source, like an inverter, should have a wattage capacity of at least 20% more than your oven. This ensures it will be able to deliver enough power as they are never 100% efficient. If you want to use a full-sized oven, you will need at least 4000W of power capacity. This will give you enough capacity to cope with the demands and not overwork your system.
Secondly, you need to ensure your energy source, like a battery, has enough energy to run the oven for the required amount of time. As we already know, it will use about 800Wh electricity for each usage. This is the equivalent to 66.6Ah on a 12V battery.
How Many Watts Does An Oven Use Summary
I hope you now have a clear understanding of how many watts an oven uses.
These are very powerful appliances that require a lot of electricity to heat up and cook food. You need to fill a large interior space with hot air. Unless you are cooking large amounts it’s not often the most efficient way to heat food. Often you are better off par-cooking or reheating leftovers in a microwave. Adding to this, if you want to run your appliance off-grid then look for low wattage alternatives or be ready for serious power consumption!
