Breville Joule Sous Vide CS10001 vs. CS20001: What’s the Difference?

You may have noticed that the leading manufacturer, Breville, offers two very similar sous-vide machines in your search for the finest sous vide machine for you to use at home. The Joule Sous Vide CS10001 (stainless steel) and Joule Sous Vide CS20001 (stainless steel) are the two models (polycarbonate).

Both appear to have the same features, so I’ll try to explain the differences between the Joule CS10001 and the Joule CS20001 (the Joule stainless steel vs. polycarbonate).

What are the similarities and differences between CS10001 and CS20001?

Breville Joule Sous Vide CS10001 vs. CS20001

The original Breville Joule Sous Vide CS10001 has a stainless steel finish on the top button and magnetic base. The Breville Joule Sous Vide CS20001, on the other hand, is a newer model with a white polycarbonate finish.

The price difference between these two sous vides cookers is due to one key difference. Because polycarbonate is less expensive to manufacture than stainless steel, the CS20001 is less costly.

These two sous vide immersion circulators are identical except for the finishing material and price. They’re both the exact compact dimensions, low weight, and powerful water heating capabilities, as well as the handy magnetic base that keeps the unit in place on most pots.

Take a look at my table below, which compares the stainless steel and polycarbonate models of the Joule Sous Vide.

Review of the Breville Joule Sous Vide

Breville Joule Sous Vide CS20001

Breville Joule Sous Vide immersion circulators are noted for their sleek design and high performance. Let’s take a closer look at the features now that you know the Joule CS10001 and Joule CS20001 models are both outstanding and work in the same way.


1. It’s slim, light, and small. The Joule sous vide machine line is the smallest on the market. The Joule is small enough to fit in a kitchen drawer, saving you a lot of counter space. The Joule is also highly portable and will easily fit in your bag if you’re on the go.

2. Bluetooth and wifi connectivity are available. To control your Joule remotely, you can use Bluetooth or wifi. To configure your cooking time and temperature, connect them to the iPhone or Android app. The app’s Visual Doneness function is a nice tool that displays you an image of how your food will look after it’s done cooking to give you an idea of how well you want it cooked. If you have an Amazon Alexa or Google Home, you can use it to control your Joule while you’re busy in the kitchen moving around and getting things done. Thanks to the wifi capabilities, you can control your Joule from work while it’s linked to wifi at home!

3. The base is magnetic. The magnetic base of the Joule is well-known. That is an extremely simple and convenient solution to keep your sous vide machine in place on most pots (metal and induction-ready pots). No problem if you wish to use a plastic container. The Joule also comes with a clip, allowing it to be attached to nearly any container.

4. The water heats up quickly. The Joule heats water faster than most other sous vide machines thanks to its high wattage. It can attain a maximum water temperature of 208 degrees Fahrenheit (98 degrees Celsius). It not only quickly preheats your water bath, so you don’t have to wait long, but it also heats the water bath precisely to your desired cooking temperature.

5. Large water capacity. The Joule’s ability to heat a large amount of water is also noteworthy. A well-insulated, covered container can heat up to 10 gallons (40 liters) of water. It can also heat up to 5 gallons of water in a covered pot (20 liters). If your container doesn’t have a lid, it’s best to keep the water capacity under 2.5 gallons (10 liters).

6. Beautiful and compact. The Joule reminds me of Apple products. It’s lovely, sleek, compact, and well-made. The design is different from the other immersion circulators in that it is elegant and straightforward. The Joule manages to cram a lot of power and functionality into a small package (much like Apple):

7. It is simple to Use. Because the Joule doesn’t have a touchscreen, all of the device’s functionalities are controlled through a smartphone app. That’s OK for almost everyone, but the Joule isn’t for you if you don’t have an iOS or Android phone.

8. Extremely powerful

The simplistic design, small size, and design are my favorite features. The Joule is tiny enough to store in a kitchen drawer. Although the Anova Precision Cooker Nano is also small enough, I believe the Anova Precision Cooker Nano’s design is better suited to the kitchen’s aesthetic.

The Joule stands a little over five centimeters (2 inches) tall and has a diameter of just over five centimeters (2 inches). Stainless steel and all-white finishes are offered for the Joule. Examine the images and tell us which one you believe is the most attractive and modern.

The Joule creates a lot of heat because of its 1100 Watts of power. In an open pot, you can heat up to 20 liters of water; in a closed sous vide container with a lid, you can heat up to 40 liters / 10 gallons of water. Why is it so crucial to have 1100 watts of power? Rapid heating to the desired temperature is required for the hot water you demand.

The Joule heats the water quickly to your desired temperature, allowing you to begin cooking sooner. Because sous vide cooks at low temperatures for long periods, it won’t cut your cooking time in half, but it will save you waiting for the water to heat up. The Joule’s maximum temperature is 208o F, which is a fantastic bargain. You won’t need to attain such high temperatures with sous vide cooking. Because it’s accurate to 0.2°F / 0.1°C, you won’t have to worry about temperatures going off.

Breville joule sous vide drawbacks

The Chefsteps Joule has numerous benefits and advantages, but it also has a significant downside for some people. There are a few things that could be better.

User interface for control

These sous vide machine is nothing more than a lovely ornamental object for your living room without your phone, internet, or Bluetooth connection.

The only “but” we have for the Joule is that it has no buttons other than the “on/off” button at the top, which is why some people do not choose it as a buying option: it has nothing but a glowing LED light and no buttons other than the “on/off” button at the top.

The mobile app on a smartphone is the only way to set temperatures and times. So don’t get the Joule if you don’t have a smartphone.


Some individuals claim that the Joule is loud, but I don’t believe that the humming sound it produces is any louder than that of other immersion circulators. Some hums irritate me, but I don’t mind the Joule’s. It’s also not loud enough for me to have a normal conversation with individuals close at a normal voice volume.


Overall, the aesthetics (stainless steel versus white polycarbonate) and cost are the main differences between the Breville Joule Sous Vide CS10001 and the Breville Joule Sous Vide CS20001. If the stainless steel finish of the magnetic base and top button appeals to you, that’s fantastic. Just keep in mind that stainless steel is more expensive than polycarbonate so that it will cost a little more.

You can’t go wrong with the white polycarbonate variant, which offers the same high-quality performance as the stainless steel version. Both of these sous vide machines are top-of-the-line. It all boils down to personal preference.
