Outdoor Gas Grill manufacturers designed these grills for several reasons. First, they are convenient to use and they are easy to maintain. They are designed to make cooking, cleaning and the maintenance easy for the casual home user. They are designed to be put in a central location on a deck or patio or they can be built into an outdoor patio kitchen. They have the option of propane or natural gas, which is best to shop for the type that is best for you. Some people prefer natural gas over propane and even in some case seems to be cheaper. If you run out, then you will need to disconnect the gas tank and go exchange it or get it filled to use.
Another reason for using an outdoor gas grill is the supplies needed. When you use a charcoal grill, then you have to buy charcoal and lighter fluid to use it. These types of grills also do not heat as evenly compared to a gas grill. If some of the briquettes do not light during cooking, then you are wasting money on that as well. Not only does it cost more money to use a charcoal grill compared to a gas grill, but a charcoal grill takes longer to cool down before having to clean the ashes out. This could lead to hours of the heat coming from grill which could be a hazard depending where it is stored. Gas grills are built using cast aluminum or stainless steel burners which cool much faster and allows you to put away much quicker without worries.
There is another advantage to using a gas grill compared to a charcoal grill. Some people will want to use a rotisserie unit for hands free operation. A gas grill has an attachment for most units, but a charcoal grill does not have this option. Some of the older model charcoal grills offered a manual rotisserie, but you had to stand next to grill and hand turn. The new gas grills offer an electric rotisserie that can be purchased for hands free roasting. The only disadvantage is that you will need to have your grill next to an electric supply or run an electric extension cord to the grill.
The advantages of outdoor gas grills outweigh the advantages of the charcoal grills that are still available, but not used as much. Most people who are still using the charcoal grill are the ones who prefer cooking with charcoal or do not have room for a gas grill. People who live in apartments usually prefer a charcoal grill because of the small size they can come in and the limited space they have. Also, people who do sporting events and haul there grill prefer charcoal grills because of the size convenience and the portability. Gas grills can be portable, but it is just not as common as the charcoal grills.
