Gas stoves are commonly made with four burners, often in two different sizes (small and large). In many stove models, the large burner will have a higher British Thermal Unit (BTU) output than the other burners for bigger cooking tasks. Size considerations and BTU output notwithstanding, there are mainly two types of burners for gas cooktops. Discover the differences between the two burner types before making a buying decision.
Standard and Heavy-Duty Burners
All types of burners made for gas cooktops output different levels of heat, which is measured in BTUs. Standard gas burners will put out approximately 8,000 to 10,000 BTUs of heat. Heavy-duty gas burner varieties found in commercial kitchens may put out heat up to 18,000 BTUs. All gas stoves require gas hookups to operate, though many are equipped with electronic ignition systems rather than old-fashioned pilot lights.
Non-sealed burners on gas cooktops are made with drip trays that are made to fit underneath the burners. A hole in the center of the drip tray allows necessary airflow to keep the fire burning hot enough to cook food. The air hole allows the burner to heat up quickly, resulting in shorter cook times than you would experience otherwise.
Sealed burners are made with spill-catching bowls which are built around the perimeter of the burner, making cleanup easier than non-sealed burner types. As the name suggests, sealed burners are made without the air hole found in non-sealed varieties. As a result of this design, sealed burners will not get as hot as quickly as their open counterparts. The advantage of using sealed burners is the easy cleanup; sealed burners wipe up very easily after use.
