Sous Vide Machines: What is Best For You?

There are many different types of sous vide machines available for the home and professional cook but they all have one purpose: to keep the cooking temperature consistent. They do this in different ways and each way has pluses and minuses.

What To Look For

When choosing a sous vide machine there are a few things to look for. People will weigh each factor differently but each one comes into play when deciding on a which sous vide machine to purchase.

Versatility and Ease of Use

Because of the differences in how the sous vide machines work there are distinct trade offs for each type. The ability to use the machine in different containers, easily control and change the temperature, and thoroughly clean and put it away are all big factors when choosing a sous vide machine.

What Does it Cost

While it doesn't affect the cooking itself, the price of the machine is important to most people. You don't want to spend $1,500 if a $200 machine will get the job done for you just as well.

Stability of Temperature

Temperature stability is the most important factor as far as the cooking process itself goes. Techniques range from a variation of several degrees to as small as 0.1°C. Another factor here is how quickly a machine can bring the water back up to temperature when cold food is added.

Stove-Top and "Beer Cooler" Sous Vide

Stove-top and "beer cooler" sous vide are the cheapest and easiest ways to check out sous vide. They use a stove to bring the water up to temperature and then either a stove or a beer cooler to hold the temperature of the water consistent while the food cooks.

It can be a very convenient (and free!) way to test out sous vide and it usually works well, especially on cooking times of a few hours or less. Longer cooking times can be very difficult to do, particularly multi-day times. It's also the least consistent way to do sous vide and the temperature is hard to accurately maintain. It's a good first step for someone interested in sous vide.

Sous Vide Temperature Controllers

Sous vide temperature controllers use a crock pot or rice cooker to heat the water while a device regulates the temperature. Basically, a temperature controller works by turning the crock pot on and off to keep the water temperature stable.

Sous vide temperature controllers are pretty easy to use, especially if you already have a good crock pot or rice cooker. They used to be the best low-cost method of trying out sous vide but the advent of less expensive immersion circulations has pushed them into the background.

Most sous vide temperature controllers are $100 to $200. I recommend either the Dorkfood or SousVideMagic temperature controllers. They both are highly thought of and have been used by many people.

Sous Vide Water Baths


Sous vide water baths are basically a self-contained temperature controller and heater with a set water bath. They used to be more popular when laboratory-grade equipped was commonly used for sous vide cooking. Now the most common water bath is made by Sous Vide Supreme, which runs $300 to $450.

In general, water baths are bulkier than immersion circulators and they are more expensive than the new line of inexpensive immersion circulators. Due to the built-in bath size you also have limited options for the size of container you will be using. Because there is no circulation mechanism in the water baths they tend to be less precise than immersion circulators but they still are usually good enough for sous vide cooking. On the plus side, because they are self contained, they are very easy to use.

Sous Vide Immersion Circulators

Immersion circulators consist of a heating element and a water pump that combine to heat and circulate the water, keeping it a very consistent temperature. The immersion circulators can be used with almost any container of water, from stock pots to plastic tubs up to 5 gallons or larger in size. This versatility is often nice, letting you cook a small amount of food in a small pot and only needing the larger sizes when cooking for a lot of people which helps save energy costs and speeds up the heating process.

Immersion circulators also have the best temperature stability of all the sous vide machines. Most machines keep it to within 1°C and many are even more stable. The pump part of the machine also helps ensure the water is evenly heated, eliminating hot and cold spots. The majority of immersion circulators heat the water very quickly as well.

Immersion circulators used to be very expensive but lately the prices have been dropping as new machines enter the market, pushing the prices from over $1,000 down to as low as $200. Because of this, I highly recommend getting an immersion circulator if you are getting serious about sous vide cooking.

The top of the line circulator is probably the PolyScience Professional Chef Series which is used in many of the top restaurants in the world and costs around $800.

Even though the PolyScience is a great machine, many of the inexpensive immersion circulators are more than adequate for home use. We recommend the Anova or Sansaire circulators, though many people also like the Nomiku. For a detailed look at the different circulators you can see our guide to inexpensive immersion circulators.
