Natural Gas & Propane Grills: Frequently Asked Questions

Choosing between a natural gas and a propane grill is one of the most common decisions our customers face. Below we answer the questions we hear most often to help you find the right fit for your backyard.

What is the difference between a natural gas and a propane grill?

The main difference is the fuel source. A natural gas grill connects to your home's existing gas line, giving you an unlimited supply of fuel and no tanks to refill. A propane grill runs on a refillable liquid propane (LP) tank, which makes it portable but requires you to monitor and replace the tank.

Can I convert a propane grill to natural gas?

Many grills can be converted using a manufacturer-approved conversion kit, because natural gas and propane burn at different pressures and require different orifices. Always use the kit designed for your specific model and have the conversion done by a qualified technician to keep your warranty valid and your grill safe.

Which is cheaper to run, natural gas or propane?

Natural gas is generally less expensive per cooking hour than propane in most regions, since it is billed through your utility at a lower energy cost. Propane has a higher upfront convenience but costs more per BTU, so frequent grillers often save money over time with natural gas.

Do natural gas grills get as hot as propane grills?

When properly sized and configured, both fuel types reach the same cooking temperatures. Propane delivers slightly more energy per unit of volume, but a natural gas grill compensates with a larger orifice and steady line pressure, so cooking performance is effectively identical.

Do I need a professional to install a natural gas grill?

Yes. Connecting a grill to your home's gas line should be performed by a licensed plumber or gas fitter to ensure the line is correctly sized, leak-tested, and code-compliant. Propane grills, by contrast, can be set up at home simply by attaching a tank.

How long does a propane tank last?

A standard 20 lb propane tank provides roughly 18 to 20 hours of grilling on a medium-sized grill. Heavy use on high heat will shorten that, so many owners keep a spare tank on hand to avoid running out mid-cook.

Are natural gas and propane grills safe to use?

Both are very safe when used and maintained correctly. Always grill outdoors in a well-ventilated area, check connections for leaks with a soapy-water test, and keep the grill away from siding and overhangs. Never store propane tanks indoors.

Which grill should I choose?

Choose natural gas if you grill often, want a permanent setup, and have an accessible gas line. Choose propane if you value portability, want a simpler installation, or do not have natural gas service at your home.
