How Does a Gas Cooktop Work?

A gas cooktop provides so many advantages to the cook and baker. It is the preferred method and the most common method of cooking for many expert chefs. A gas cooktop may come with an electronic ignition and many griddle accessories.

The Heating Process

A gas cooktop is usually heated with propane or natural gas. There may be an individual propane tank on the exterior of the home dedicated solely to the gas cooktop or if you have a gas line running into the home from the public utility supply, the gas cooktop will be heated with the fuel from the natural gas.

The Electric Igniter

The average gas cooktop has an electric igniter. The electric igniter is responsible for turning on or starting the pilot light. The electric igniter is usually ignited by both turning the burner’s knob to the "ignite" position and pushing down the ignite button. You must do this for each burner individually.

The Pilot Light

In some styles of gas cooktops, the pilot light remains on all the time.  With this style of cooktop, you will not have or need to use an electric igniter.

The Knobs

The height, size and strength of the gas flame for each burner is controlled through the individual knobs on the burner. This is ideal for any cook. It allows you to control the intensity of the heat during your cooking process thereby reducing the chances of burning your food or your cookware. The knobs are easy to wash and clean. They can be put in the dishwasher by just pulling them off gently from the thin base. You will find a small rubber ring sitting between the knob and the gas cooktop base. This ring may also be put into your dishwasher for a complete clean. 

The Down Draft

In most homes you will find a gas cooktop that has a down draft. The downdraft is responsible for releasing excess exhaust, heat or fumes (such as cooking oil fumes) from the house and to the outside. Access the downdraft on your cooktop by a knob. The knob will either be located on the top of the cooktop (such as the top of a ceramic cooktop) or on a front panel. The electronic parts and components of the down draft are usually found underneath the cooktop’s cabinet.

The Heating Elements

Heating elements come in a variety of shapes and sizes. The majority of heating elements are either ceramic or stainless steel. The elements are responsible for conducting the heat throughout the bottom of your pan, pot or other cooking and baking accessory. The elements sit raised up 2 to 4 inches over the flame.

The Eye

The eye of the burner is where the flame escapes into the confines of each burner.

The Surface

On a gas cooktop, the surface comes in many different shapes, sizes and materials. Often made of ceramic, the surface of the gas cooktop is designed for easy cleaning.
