Gas hobs are cooking appliances that use natural gas or propane as a fuel source. They consist of burners that provide direct heat for cooking, allowing for precise temperature control. Gas hobs are popular in many kitchens due to their quick heating capabilities and the ability to instantly adjust the flame. These hobs come in various sizes and configurations, often featuring multiple burners to accommodate different cooking needs. They can be built into countertops or used as standalone units. Safety features, such as flame failure devices, are commonly included to prevent gas leaks when the flame goes out.
