Fuel Options For Gas Grills
While both types of fuels typically produce the same flavor in food, there are some differences between the two. Below, we’ll look at these two types of fuels and their differences.
Natural Gas
Using natural gas requires a hookup to a gas line, which some homes have and others do not. If a home already has appliances that run on natural gas, a professional can extend the gas line to a deck or outdoor kitchen. Natural gas for grills offers simplicity and consistency with cooking and doesn't infuse food with smoky flavors. If you have a propane gas grill that can also run on natural gas, you can purchase a natural gas conversion kit, complete with a gas hose, to make it possible to do so. Not all propane grills are convertible to natural gas and sometimes converting your grill can void the warranty. It’s important to check if your grill is convertible before purchasing a natural gas conversion kit.
Propane
Propane grilling requires propane tanks, which can be found at some hardware stores, gas stations and other suppliers. Propane for gas grills is refillable or exchangeable at most Lowe’s stores. Not all propane tanks are refillable, however, so it’s important to choose a refillable option if you want to be able to reuse the tank.
Just like natural gas, propane won’t infuse food with smoky flavors like other fuel types including wood chips or charcoal briquettes. Also called liquid propane, propane is compressed in a liquid state and put into portable tanks to be transferred. 20-pound propane tanks are most common for grilling, but there are tanks in other sizes as well. Take a look at our propane tank guide for tips on choosing the right tank for your home.
Propane Versus Natural Gas
Natural gas is only available in places where a gas pipeline system is present whereas liquid propane can be delivered to any location within access to a local fuel provider. Another difference to consider is that when a propane tank is empty, you'll be without fuel until you can replace or refill your current tank. One benefit of grilling with natural gas, on the other hand, is that it's unlimited and doesn't require refilling.
Liquid propane is obviously better from a portability and convenience standpoint, as you can set up a propane tank anywhere – like a tailgate or second home. As far as cost, natural gas is typically cheaper than liquid propane, after initial set-up costs associated with installing gas lines.
Other Fuel Types
Aside from liquid propane and natural gas, there are several other fuel options to choose from including lump charcoal, electricity, wood pellets and more. To learn about each fuel type, read our guide on grilling fuels.
