Gas bbq grills are still often used as they are easier to light and easier to control. Although they may cost more than charcoal grills or even the popular ceramic grills, gas BBQ grills are much easier to clean and have a lifespan that far surpasses that of any other grill.
What a consumer needs to consider before purchasing a gas bbq grill:
First, look for a gas grill with several temperature settings – Getting a BBQ grill with temperature settings allows you to have more control over the heat and will ensure that you do not over grill your food. It can also be used to sear and slow-roast your food if you desire.
Porcelain-coated cast iron grill grates – Porcelain coated cast iron grates help to distribute the heat more evenly across the surface of the gas grill.
The grates are closely spaced and decently wide – You don’t want a grill with grates that are spaced too far apart because your food will have a higher tendency to fall through.
BTU’s – The BTU level (or the heating power measurement) of a gas bbq grill has a large bearing on the success of your grilling. Other factors that can affect the heating power other than BTU are the size and geometry of your BBQ grill as well as the heat distribution mechanism.
Gas bbq grills are convenient, easy to use and are much easier to clean which makes them, by far, my personal choice over a charcoal grill.
