Open vs Sealed Burners

When buying a new gas range you'll need to choose between open or sealed gas burners. There are many debates about which one is better. Some people, like professional chefs, argue that open burners are more efficient, while sealed burners are most commonly bought by home cooks for residential use. Our guide will help you choose between the two types of burners by informing you about their advantages and disadvantages.

Open Burners

Open burners have an open flame coming up directly from the center of the burner which creates more direct heating to the pan. Since the burner components are exposed, more air can circulate around the flame increasing the heat output which makes open burners more powerful. The design has its advantages and disadvantages.

Pros: The biggest advantage is the efficiency. Since open burner configuration directs the heat to the center of the pan, it results in more even and faster cooking than on the sealed burners. Additionally, open burners allow for better control over your cooking, such as being able to simmer at lower settings.

Cons: Open burner might be advantageous for the faster cooking but it has a downside when it comes to cleaning. Since its components are exposed, if anything boils over or spills on the burner, it will fall in the flame and go down inside the range. However, ranges that offer open burners usually have a drip tray which catches anything that goes inside the burners. Due to open structure, the burner parts has to be removed in order to clean them.

Sealed burners have a cover between the burner and the flame. In opposite to open burners, the burner components are usually covered, so they are not as exposed to the air. This type of burner is often found in residential kitchens.

Pros: The biggest advantage of the sealed burners is a cleaning convenience. The seal between the burner and the frame keeps the spills contained. So, you don't have to remove the parts to clean them. You can simply wipe off the dirt from the surface. Sealed burners are also considered visually more appealing in the residential kitchens.

Cons: Gas ranges with sealed burners are more expensive than the ranges with open burners. Another disadvantage is that sealed burners have less heat output than open burners because of the covered surface. So, The heat is directed more around the pan rather than in the center, therefore, the heating is uneven and less efficient compared to open burners.

Thermador's unique star burner design is an exception to the rule. While people often think that the shape of the star is just a new visual design, it actually has a purpose. This unique design helps in reducing cold spots and delivering more flame spread for the pan. This means that more heat is directed to the center of the pan which results in faster and even heating across any pan size.
