How to choose between natural gas and propane

If you are still wondering whether to choose a natural gas grill or a propane grill, here are the main advantages and disadvantages of each of the types so that you can decide which one will work better for your specific needs.

Natural gas pros

Natural gas, which is a greenhouse gas called methane, is the natural alternative to liquid propane gas. The main pros of natural gas grills include:

Connecting a natural gas grill to your home’s existing gas pipeline means that you don’t need to worry about running out of gas in the tank and that you need to stop cooking and go for a replacement if you happen to run out of gas. With a natural gas grill, you will have a continuous and stable supply of the fuel you need at all times.

While it may not burn as clean as liquid propane, methane is still considered an environmentally friendly fuel with low carbon dioxide emissions, especially when compared to traditional charcoal grills.

When compared to liquid propane, natural gas is cheaper per gallon. In fact, natural gas can cost about 1/6 less than propane. In the long run, if you already have a gas line at home, you will save money for having to buy the more expensive replacement propane tanks for your gas grill if you install and use a natural gas grill.

Of course, your usual gas bill will increase slightly when you install your natural gas grill, but if you only use it occasionally, the increase will be less than buying a replacement propane tank.

Natural gas cons

Here are the main disadvantages to keep in mind before buying and installing a natural gas grill:

What makes natural gas grills better than propane grills, namely the continuous and reliable supply of gas at all times, also makes them harder to install. Installing a natural gas grill in your outdoor space will not be such a problem if you already have an existing natural gas line and a suitable outlet for connecting it to the grill. But you don’t have one readily available, you will need to install a dedicated one for the grill, which is a complicated process and can require getting permission and hiring a licensed plumber.

Another disadvantage of natural gas grills is that they are typically more expensive than their propane gas alternatives. Plus, if you need to have a gas line or valve installed, you will need to hire a licensed expert, which too costs money.

In some areas, you will need a special permit to install a natural gas grill from the local authorities and from your gas company.

Also, once you install the grill and connect it to the gas line, it is much harder to move the grill or change its position than when using a freestanding propane grill.

One thing that some pitmasters disliked about the first natural gas grills was that methane burns at almost half of the heat of propane. This meant that you might have problems reaching very high temperatures for quick and high grilling and searing on a natural gas grill, as compared to a propane grill. Today, with modern natural gas grills, this problem has been eradicated.

Propane gas pros

Propane gas grills are more popular than natural gas grills due to the following advantages they have:

Setting up and installing a propane gas grill is much less complicated than installing a natural gas grill.

Replaceable propane tanks are portable, so you don’t have to worry about hooking up your grill to a specific pipe outlet and fixing it in place. Instead, you can move a standalone propane gas grill, and there are many portable gas grills that you can take camping and outdoors with you. Plus, if you don’t have a gas line at home, you cannot install a natural gas grill anyway.

Propane is the cleanest burning of all fossil fuels on the planet. It is also environmentally friendly and will not pollute the soil or water if it leaks.

While propane may be the more expensive alternative to natural gas, it does produce more heat than its natural alternative. A cubic foot of propane can produce up to 2,516 BTUs, while the same quantity of natural gas will produce only up to 1,030 BTUs. So, you will be using half the amount of propane as compared to natural gas for the same cooking task.

Propane gas grills are usually less expensive than their natural gas alternatives, so your initial investment will be lower than if you invest in a natural gas grill.

Propane gas cons

What has considered the biggest downside of propane gas grills is the fact that you will need to make sure you buy and replace your propane tank to avoid being left without fuel in the middle of a cooking session or when you need to use the grill. This is not only time-consuming and can be frustrating but will cost you money for running the grill.

In the long run, it is more expensive to run a propane tank than a natural gas one, as each replacement tank can cost between $10 and $20.

Which one burns hotter – propane or natural gas?

As mentioned previously, propane gas burns almost twice as hotter than natural gas. The difference is 2,516 BTUs for a cubic foot of propane compared to 1,030 BTUs for a cubic foot of natural gas.

Some pitmasters even claim that they cannot get their natural gas grills to reach the high temperatures needed for searing and other cooking at high temperatures. But while this used to be true for the first natural gas grills, today, the good grills will automatically increase the gas released to the burner when higher temperatures are required.

Some of the top natural grills on our list also include infrared burners, which can easily achieve high temperatures much quickly and can be used as searing stations.

What makes natural gas grills more expensive?

In most cases, when the same gas grill is available in both options, the natural gas one is more expensive by $50-$100.

The reasons for this are the longer gas hose of at least 10 feet and the brass fittings and stop-valves, which come with the grill for connecting it to the gas pipe.

Can propane grills be converted to natural gas grills?

Most of the propane gas grills can be converted to natural gas with a compatible conversion kit which includes a flexible gas hose, quick connect brass fittings and valve limiter stops, and suitable gas jets.

It is recommended that you check with your local legal and planning authority requirements before connecting the grill to an existing or building a new natural gas supply. In some states and areas, a permit and a more stable connection than the flexible hose installed by a licensed expert is required.

Keep in mind that using a conversion kit on some propane grills will void their warranty.

Is it safe to use a natural gas grill?

While the use of any gas grill does hold some safety and health hazards, chances are that if you are already using gas at home, it will be safe to use a natural gas grill when it is connected and used properly.

Here are some tips for using a natural gas grill safely:

  • Ensure that there are two shut-off valves – one next to the grill and the other next to your home. This will prevent the spread of an eventual fire.
  • Do not close the lid when you are lighting its burners (this is true for any gas grill).
  • Clean any grease and debris from the grill after use to prevent flare-ups.
  • Install the gas grill away from awnings, eaves, or deck railings.
  • Turn the two shut-off valves off after using the grill.

In conclusion

Using a natural gas grill will allow you to enjoy a steady supply of fuel whenever you need to use the grill. You won’t need to worry about having to buy replacements or, even worse for running out of gas in the middle of a grilling session.

Hopefully, we have helped you decide whether you should invest in a natural gas grill and which one will be the most suitable for you.

So, good luck with your purchase, and happy grilling!
