The most important aspect of which to use, natural gas or propane, all depends on a matter of personal preference. Just like the different sauces, temperature settings, cook times and choice of meat it is all a personal choice. There is no difference when grilling with gas (NG) or propane (LP)as both of these are clean fuel sources and supply quick high heat for your BBQing.
Even though both are great, there are some different situations where one might work over the other. Remember, you cannot use natural gas with a propane grill or propane gas with a natural gas grill. The reason for this is that the gas openings are different sizes for natural gas and for propane gas. Here are some characteristics that separate natural gas from propane gas.
Natural gas has the advantage of running through the home like your water or electricity. If you already have gas running to your home, then this would be your best choice. When purchasing a natural gas grill, the unit should come with a kit that helps in hooking up the grill to the gas line. Natural gas is a cheaper option and will never run out in the middle of cooking your steak! On the flip side, if you do not have a gas line running to your home, it can be expensive to install a gas line to your home and destroy your backyard by laying new lines.
Remember natural gas will save you money in the long run and is one of the most eco-friendliest fuel sources on the market. If you do have natural gas and natural gas appliances, you will never have to worry when you lose electricity.
Liquid propane is nice because you can move your grill around. LP gas comes in small tanks that can sit beside or inside your grill. When you run out of propane, you can take your tank to a store that sells grills and purchase a refill. You will need a hose and regulator which will supply the gas to your grill.
Remember both products are great for using and cooking meals to perfection. It is really your personal preference when it comes to which fits your lifestyle.
