One of the most common types of domestic appliances is a refrigerator. Refrigerators use up to 10kW, while freezers can range from 0.5-10 kW depending on your needs and power supply available in your home. This article will walk you through how many watts it takes for an individual appliance based on some basic math formulas!
The “how many watts does a deep freezer use” is a question that has been asked for years. The answer to the question depends on different factors, but it is typically around 10-15 watts per day.
Refrigerator power estimates abound, but there are none for freezers. It’s a pity, since you wanted to buy a freezer. So, how much power does a freezer consume?
We’ll show you how to calculate freezer power consumption and find out the average freezer wattage consumption in this post. We’ll also discuss factors that influence freezer power consumption as well as ways to reduce freezer power consumption.
Average Freezer & Refrigerator Wattage Consumption
Depending on the size and model year, a freezer consumes 300 to 700 watts. A 13 cubic foot frost-free freezer, for example, uses roughly 300 watts, but a 20 cubic foot chest freezer uses 350 watts. A freezer that is older will use more energy than one that is newer.
- Which method saves the most electricity? It’s impossible to say if a freezer saves more energy than a refrigerator since it depends on how you use your appliance and the size of your freezer or refrigerator. In general, whatever serves you best will save you more energy in the long run since it is the most appropriate size for the job.
- Where can you get a freezer’s wattage information? When you purchase a freezer, refrigerator, or any other appliance, it will come with a power rating label. There are estimates for its wattage and power usage. Alternatively, you may check for the nameplate on your freezer. It’s imprinted on the back or bottom of the freezer, and the maximum wattage output is shown there.
- Is it true that a freezer always uses the watts stated on the label? The power consumption mentioned on a freezer’s label is not always used. Keep in mind that a freezer provides customization options like high, medium, and low cold. Others may even feature temperature control capabilities. Your total wattage and power usage will be affected by the settings you choose.
Freezer Consumption Calculator
Follow these procedures to determine how much a freezer costs in terms of electricity:
- Start by multiplying the wattage of the freezer by 1000.
- Multiply your result by the number of hours the freezer has been switched on.
- Multiply your new figure by the cost of power per kilowatt in your state.
Visit your electrical company’s website or check at your energy bill to find out how much power costs per kilowatt in your location. It should be included in the package.
Factors Affecting Freezer Electricity Use
The size, location, kind, use, temperature setpoint, age, condition, and season are the most prevalent factors that influence freezer power utilization. All of these variables, when considered together, will have a major impact on your power bill:
- Size: The bigger your freezer is, the more electricity it uses.
- Placement: If you keep your freezer in a poorly ventilated room or in a warm or hot environment, it will use more energy.
- The sort of freezer you have will impact how much electricity it uses.
- Usage: If you open the freezer often or if it is virtually always empty, it will consume more electricity.
- Temperature control: Some freezers have a degree setting, and if you set it to a lower temperature, it will need more energy to maintain that temperature.
- Age: When compared to previous freezer models, newer freezer models use less energy.
- Condition: If your freezer is old and has lids that allow air to escape and leak, it will consume more energy since the majority of the cold will escape.
- Summer is usually associated with greater electricity use than winter.

How to Reduce the Power Consumption of a Freezer
If you’re concerned about your freezer taking too much electricity, you may take steps to lower its power usage. They’re straightforward, straightforward, and straightforward. Picking the correct placement for your freezer, cleaning your freezer, adjusting the temperature in your freezer, and defrosting your freezer are all things to consider.
- Choose a suitable place for your freezer. The coolest possible location in your home is ideal for your freezer. It must be kept away from heat sources such as the sun or the oven.
- Make sure your freezer is properly ventilated. This will keep your system from breaking down or overheating in the future. It will also reduce your energy use, since overheating might result in increased consumption. As a result, don’t block airflow apertures, and don’t put your freezer too near to the wall.
- Take note of the climatic class of your freezer. Most freezers feature a label that specifies the environment for which they were designed. The letters N, SN, ST, and T are used on these labels.
- If the temperature is below 16°C (60.8°F), your freezer will not be as efficient.
- If the temperature is below 10°C (50°F), SN indicates that your freezer will be ineffective.
- ST indicates that your freezer will perform well in temperatures ranging from 18°C (64.4°F) to 38°C (100°F).
- T implies that your freezer will function properly at temperatures ranging from 18°C (64.4°F) to 43°C (109.4°F).
- Set the appropriate temperature. A freezer’s ideal temperature is at -18°C (-0.4°F). If you raise the temperature by one degree, your power usage will rise by 5 to 10%.
- If required, replace the door seals on your freezer. If you notice that your freezer’s door seals aren’t working as well as they once did, it’s time to replace them. This will save you a lot of electricity while also increasing the efficiency of your freezer.
- Clean your freezer on a regular basis. Cleaning your freezer on a regular basis implies cleaning it at least once every three months. Similarly, clean the exterior of it. Wipe the dirty coils and the borders. By the time you check below it, there will be a layer of dust on top of it.
- Fill the freezer to at least 34% capacity. Of course, if your freezer is almost empty, you’ll be chilling empty space instead of food. As a result, at least three-quarters of your freezer’s capacity should be filled with frozen foods.
- At the very least once a year, defrost your freezer. This is done to prevent ice from forming. The electricity usage of your freezer might be increased by 10% due to ice formation. Similarly, ice accumulation will make it more difficult for your freezer to perform effectively and efficiently.
- At least twice a year, check your freezer for symptoms of danger. Examining your freezer for potential problems is an excellent method to avoid excessively high future power use. Freezers that are broken will always use more energy than freezers that are working properly.
Last Thoughts
A freezer uses 300 to 700 watts of power. A 13 cubic foot frost-free freezer will use around 300 watts, whereas a 20 cubic foot freezer would consume approximately 350 watts. In general, modern freezer models use less energy than older models.
Look for your freezer’s nameplate and verify its power rating to determine its watts. However, keep in mind that a freezer’s power consumption isn’t the only aspect that determines how much energy an appliance uses.
What Happens If You Leave Your Refrigerator Door Open?
A freezer uses up to 40% less electricity than a refrigerator. A typical refrigerator will use around 10-12 kWh per day, while a freezer will only use 3 kWh. Reference: does a freezer use more electricity than a fridge.
