Burner Types on Slide-In Ranges: Sealed, Open, and More

Burner words on a listing

Gas slide-in range listings describe the cooktop by burner type. The words sealed, open, power and simmer tell you how each burner is built and what it is for. A listing may put these words in the title, in the bullet list or in the feature list near the model name.

The burner type matters because it shapes how you cook and how you clean. Sealed burners are the common layout on modern gas ranges. Open burners appear on commercial-style models. Power and simmer burners are specific positions on the cooktop, usually the largest and smallest outputs. See how burner types fit into the full slide-in range reviews on this site.

Sealed burners

Sealed burners have the burner head and cap joined to the cooktop surface. Spills stay on the cooktop instead of dripping into the cabinet below. That is why most gas slide-in ranges use sealed burners and why many listings say sealed burners in the title. If you want minimal cleanup around the burners, sealed is the common choice across gas slide-in ranges.

With sealed burners, grates sit over the burner and lift off for cleaning. The area under the grate is a flat surface you can wipe. If a listing does not say sealed, it often says gas burners with a photo showing the sealed layout. The cooktop grate design article explains how grates work with sealed burners.

Open burners

Open burners expose the flame in a burner bowl below the grate. The look is closer to a commercial kitchen range. Some premium and pro-style slide-in ranges use open burners for that appearance and for the way the flame wraps around the pan. If this is the look you want, browse premium slide-in ranges and read the burner words in each title.

Open burners can be more work to clean because spills can fall into the burner area. If the listing only says gas, you may need the maker's page to see whether the burners are sealed or open. The sealed vs open burner comparison covers the cleaning and cooking differences in more detail.

Power burners

Samsung's range pages list a Power Burner on several slide-in gas models, with ratings of 23K BTU, 18K BTU and 17K BTU on different configurations. The power burner is the large-output burner on the cooktop, meant for boiling water and searing in a wide pan. When a listing names a power burner, it usually gives the position and the rating.

LG describes its UltraHeat burners as designed to rapidly boil water and provide true simmering. So an UltraHeat burner can serve as both the high-output burner and the low-heat burner in one position. Look for power burner, ultra heat or dual burner in the listing to identify the high-output position. The wok burner vs power burner article explains the differences for high-heat cooking.

Simmer burners

A simmer burner is a low-output burner for gentle heat. It keeps sauces at a slow bubble, melts chocolate without scorching and holds a pot just below boiling. LG's page uses the phrase true simmering for its UltraHeat burners, showing that low-heat control is a design goal. If you cook delicate dishes, look for the word simmer or dual burner in the feature list.

Not every gas slide-in range lists a dedicated simmer burner. Some have a dual burner that runs at high or low output in the same position. The burner BTU vs simmer guide explains how high and low output work together on the same cooktop.

Reading burner types on a listing

A listing usually names the burner type in the first words of the title. One listing may say gas slide-in range with sealed burners, another may say 5-burner gas range with power burner. The bullet list then tells you which burner is the power burner and whether a simmer burner is included.

Compare two listings by looking at the same words. One may say sealed burners, another may say open burners. One may list a 23K BTU power burner, another may list a 17K BTU. The stated details are what you can compare. If a detail is missing, the maker's page or the manual answers it. The 4 vs 5 burner article looks at how burner count changes the cooktop layout.

Safety notes

The U.S. Fire Administration says unattended equipment is the leading factor in home cooking fires. Its cooking fire safety guidance is simple: stand by your pan, turn the burner off if you leave the kitchen, watch what you cook, turn pot handles toward the back of the stove and keep a pan lid or baking sheet nearby to cover a pan if it catches fire.

The burner type does not change those messages. Sealed or open, power or simmer, the same rules apply. The maker's installation instructions and local codes decide gas connection questions; a qualified installer answers them.

What to pick for your situation

Questions

What is a sealed burner on a gas range?

A sealed burner has the burner head and cap joined to the cooktop surface, so spills stay on top instead of dripping below. Most modern gas slide-in ranges use sealed burners.

What is an open burner?

An open burner exposes the flame in a burner bowl below the grate, giving a commercial-style look. Open burners can collect spills in the burner area, so they may need more cleaning attention.

What is a power burner?

A power burner is the high-output burner on a gas cooktop, positioned for boiling water and searing. Samsung lists Power Burner ratings from 17K to 23K BTU on different slide-in models.

What is a simmer burner?

A simmer burner runs at low output for gentle heat, for sauces, melts and holding a pot just below boiling. Some ranges offer a dual burner that covers both high and low output in one position.

How can I tell which burner is the power burner?

Read the bullet list on the listing. It usually names the power burner and its rating, and the cooktop photo shows which position is the large burner.

Do all gas slide-in ranges have sealed burners?

No. Sealed burners are common, but some premium and pro-style models use open burners. Confirm the burner type in the title or bullets, or check the maker's own range page.
