Gas grills use either natural gas or propane, rather than charcoal, as fuel for cooking food. Some people prefer gas grills to the traditional charcoal options because of their ease of use. With a gas grill, there are no charcoals to arrange, light and heat up before grilling. When you're ready to grill, you simply turn a gas grill on and you're ready to get started.
Some gas grills use propane as their fuel. These grills typically require a propane tank, which fits underneath the grill and provides the fuel needed to create flame when it's time to cook. Often, propane grills are described as effortless cooking devices, as you simply use an ignition button or switch to start the flames and to turn them off again when you're done. These grills can retain a set temperature for a long period time, as they often have temperature-adjustment buttons, similar to those you might find on an in-home stove.
These grills can be small and portable, making it easy to use them in any part of a backyard or patio as well as take them along for tailgate parties. However, there are also very large propane grills that are meant to be kept in one place for a long period of time. With propane gas grills, it is necessary to get refills of propane when the fuel runs out. To do so, you simply take the propane container, which usually resembles a large opaque bottle, to a propane-refill location, such as a home-improvement store, gas station or a hardware store. An attendant will usually refill the bottle or container and give it back to you.
Natural gas grills are also very popular; the can be used both inside and outdoors; they typically require hooking up to a natural gas line. For example, a person may hook a gas grill up outside but have it connected to the natural gas source coming from inside his home. Natural gas grills provide the same ease of use as propane models, often coming with a single ignition switch for quick starting as well as rows of knobs for regulating heat. They also come in a wide variety of shapes and sizes, and there's no tank to refill. As such, there's no risk of running out of fuel at inopportune times.
