Charlies Reviews and Ratings of The Best Natural Gas Grills

1. Weber Genesis II S-335 Natural Gas Grill

The Overall Best Natural Gas Grill

My pick for the best natural gas grill is the Weber Genesis II S-335 grill. We all know that Weber produces quality grills, and this wasn’t an exception when I tested it. You know a brand is good, when it has been around this long!

Specifications

  • Weight: 190 pounds

  • Dimensions: 33 x 39 x 26 inches

  • Primary Cooking Space: 646 square inches

  • Total Cooking Space: 844 square inches

  • Burners: 4

  • BTU Output: 48,000

  • Wheels: 2 wheels and 2 casters

Why We Like It

As we all know Weber products can last for decades, so I know ill be passing this one down to my son.

It has an impressive 844 square inch cooking space, which meant I was able to feed everyone at our daughter graduation party. It is a perfect unit for anyone who likes entertaining in the back yard on a regular basis!

It has an excellent ignition system. Throughout my testing I have had no issues with the unit firing up whatsoever. One of the major reasons I buy Weber, is the peace of mind you get with their famous warranty.

A few extra things I liked were;

  • Extra space inside the hood: The grill is tall enough to cook beer butt chicken. It is built like a tank and has drip guards that catch grease quickly. Its burners are slid into place rather than screwed, so I found that rusting was minimal.
  • Even distribution of heat: The heat produced from the burners cooked my food evenly. I really like when grills don’t have hot and cold spots
  • Easy to use and start: The ignition system of the GS4 (as it is popularly called) is one of its best features. I found this grilled started easily each time we used it. Weber calls it the infinity ignition, and it works pretty well.

What I Didn’t Like

  • Side burners are not included: Its disappointing that this grill does not have side burners. Its four burners are just enough, but one of two side burners with them would have been preferable (especially when I want to sear my steak).
  • Its a heavy unit: At 190 pounds, I found it difficult to move alone, even with its wheels.

I wasn’t sure if the natural gas grill would be as powerful as my propane grill. But as usual Weber has put together a top quality product. it a griller’s dream unit and have recommended it to many friends and family members. Just don’t try to move it alone, it’s heavy!

2. Weber Spirit II E-310 Natural Gas Outdoor Grill

The Overall Best Natural Gas Grill – Runner Up

Weber Spirit II E-310 Natural Gas Outdoor Grill

The Weber Spirit II E-310 comes in as our best overall runner up. I think of it as the little brother of 335.

It is a little more compact than the 335, which means less cooking space. I think more suited to weeknight cooking than big cookouts.

Specifications

  • Weight: 110 pounds
  • Dimensions: 5 x 52x 27 inches
  • Primary Cooking Space: 424 square inches
  • Total Cooking Space: 529 square inche

  • BTU Output: 30,000
  • Wheels: 2

Why I Think You Should Consider It?

It might sound silly but one of my favorite features were the foldable side tables. You don’t realize how handy it is to have some extra prep space in your outdoor kitchen

Like most grills made by Weber, the E-310 has reversible cooking grates. I found there helpful for cooking fish or sides!

This unit is also easier to assemble, but it was heavy so you might need some assistance to lift move it around the yard.

What I Liked About It

  • Excellent distribution of heat: The three burners meant I didn’t have any hot or cool spots.  
  • Ignition system worked every time: The ignition works perfectly every time I started it.
  • Easy assemble: It only took me and my son an hour to assemble it
  • Natural gas connection: We were able to hook up this grill to our natural gas line. That mean no more trip to the gas station to fill our propane tanks

What I Didn’t Like

No side handles: Even though this grill has wheels, it is quite difficult to move around.

Overall Thoughts

I think this is the perfect match for someone looking for a weeknight grill. It’s easy to fire up and get to temperature fast! That’s mean we were able to get dinner on the table fast (perfect for our hungry little kids)

I love Weber’s 10-year warranty on all the parts. It always gives me a piece of mind, especially when I am spending a fair bit of money.

Our best high-end grill spot goes to another Weber product. This time, it is the Summit S-470

We liked it that it came with a metallic smoker box, with its own burner. That meant I could add smoky flavors to my cooks.

At my son’s 2nd birthday we managed to fit feed 20 hungry adults and 12 kids with ease.

We found the flavorizer bars to worked perfectly. They channeled the grease away from the burners, eliminating flare-ups while we were cooking.

The Best Built in Natural Gas Grill

Do you want to own a top quality grill? Then the Napoleon might be the winner for you!

It heated up extremely well with its four primary burners with a BTU output of 48,000. We found the side burner wasn’t just for boiling or warming food. It can get up to 1,800 Fahrenheit in only a few seconds. That meant I was able to sear my steaks quickly!

We like the Jetfire ignition system. It made cranking up the heat, no problem at all.

What is Natural Gas?

Natural gas is a fossil fuel that forms deep beneath the earth’s surface. This gas is a rare, odorless, non-toxic substance containing high proportions of methane. Propane, electricity, and charcoal are conventional grilling alternatives to natural gas.

Are There any Benefits to Cooking with Natural Gas? (5 Reasons Why)

Natural gas is the perfect choice for cooking. We like that natural gas ignites, burns, and reaches the desired temperature quickly, making cooking time very short. Some other benefits of natural gas include;

1. No More Worrying About Gas Bottle Levels!

This is one of the most amazing benefits of cooking with natural gas. A hose connects the grill to the gas line of your house. Unlike propane and charcoal grills that use up fuel quickly, you do not have to refill your gas bottle or add more charcoal continually.

 You will never run out of gas while cooking with natural gas grills

2. Saving Money

Natural gas grills save a lot of money for you in the long run. The only significant cost you may have to incur is in installing a gas line, if you do not already have one. If you cook a lot, you will be please to learn that cooking with natural gas is much cheaper than using propane tanks.

3. Natural Gas is Better For the Environment

Using a natural gas grill to cook reduces environmental pollution. It is the cleanest grilling gas and when burned, releases only a small amount of oxides, and almost no ash or smoke (which could end up on your food).

4. Easy Installation

A natural gas grill needs to be connected to the main gas supply in your house, so a line must be installed. The process is easy and quick. You just need to contact a professional

5. Environmentally Friendly

The carbon emissions to the environment are also significantly lower in natural gas grills than others. Natural gas is an eco-friendly grilling option.

Can You Use Propane in a Natural Gas Grill

Using propane in a natural gas grill is like putting a square peg in a round hole. It doesn’t work!

The energy and oxygen ratio needed for combustion in these two grilling gases are very distinct, making either unsuitable as replacements. A few accessories like hoses and regulators of each of these gas grills do not fit in the other.

Quick Overview: Converting from a Propane Grill to a Natural Gas Grill

Converting from a propane grill to natural gas grill would ensure that you never run out of fuel.

However, not all gas grills can be converted to natural gas. Check the grill’s manual for a dual fuel logo or any similar sign that will indicate that the grill is convertible.

You will need a natural gas conversion kit. Again, not all grills use the same kit, so make sure you get the right one.

Note: These instructions are intended to be an overview Not as a step-by-step guide to follow yourself.

 Making the conversion yourself is only recommended if you have the necessary qualifications. If in doubt please do not attempt yourself, consult a professional.  

  1. Turn all knobs and regulators to the ‘Off’ position and cut off the propane gas tank’s supply. Then, remove the tank from its regulator.

  2. Next, remove the warming wraps, cooking grates, and panels. Then, remove the hitch pins and carryover tubes. Do not forget to remove these pins from the back as well.

  3. Disengage the burners from the valves by sliding them over carefully. Use the orifice removal tool to unscrew the orifices from the grill.

  4. Pull out the burner control knobs from their stands and unscrew the washers and screws that secure the knob to the grill’s body.

  5. Put the new bezels on the control knob stand and fix the knobs back to the bezels.

  6. Reinstall all tube burners, panels, and tanks. Finally, put the natural gas tank and orifice in place for grilling.

Note: These instructions are intended to be an overview to show you the steps. Not as a step by step guide to follow yourself. Making the conversion yourself is only recommended if you are confident and have worked with natural gas before. If in doubt please do not attempt yourself. Consult a professional.  

How to Choose the Best Natural Gas Grill (11 Things You Need to Think About)

There are many options when it comes to natural gas grills. So selecting one can pose quite a challenge. Here are some of the things to look out for and questions to ask yourself before you buy one.

The BTU Rating

The BTU of a grill represents the maximum power output that it can provide. The size, cooking surface, number, and power of the burners will help you decide how powerful your natural gas grill needs to be.

The Size of Gas Grill

Think of the number of people you will be cooking for. Do you intend to use the grill for big cookouts, family dinners, competitions, or lunch? The size of the grill you need should be large enough to cater to your guests (or family).

You will have to keep people waiting for their food while cooking many portions if you buy a smaller grill than what is required. Also, it would be a total waste to get a larger one when you do not need it.

Cooking Surface Area

Another thing to keep in mind when determining the size of the grill is the cooking surface area. A grill can look big but have a small cooking area. The area is measured in square inches, and 450 to 500 square inches should be sufficient for small family meals. For a family of around 5 or 6 you should be looking at 550 to 650 square inch grills.

The cooking space or area is divided into two: primary cooking space and secondary cooking space. The area just above the grates and burner is called the primary cooking space, and this is where most of the cooking or grilling is done.


The secondary space includes all the side burners and racks that you could open up to allow more space for cooking. If you intend to use your grill to cook for several people at a time, then a sizeable secondary space is necessary.

How Much Space Do You Have Available?

How much room do you have for your grill setup? Do you intend to use it in your porch, balcony, or backyard? Natural gas grills can be quite large.

Burners

Burners are vital components of any grill, and natural gas grills can have up to 8 burners, although this is very rare. They are the heating element in the grill, and so determine how hot the grill gets when food is being cooked.

Burners have different configurations that allow for versatile cooking. They could be made from materials like brass and aluminum, and supply various temperatures. Here is everything there is to know about burners.

Burner Materials

There are many materials used to make burners. The general thing that all of them have is the ability to withstand intense heat and pressure for an extended period.

Four common materials used in making burners are brass, cast iron, stainless steel, and aluminum, with stainless steel burners being the most popular.

304 stainless is the best grade of stainless steel used in making these components
. It contains about 18% of chromium and 10% of nickel but is not the most used grade in grills. A lot of average-priced grills are made from 430 stainless steel, which would corrode faster than the 304 grade. A magnetic test is a good indicator of the burner’s quality, with 304 stainless steel burners being almost non-magnetic.

The second material that burners are made from is cast iron. Cast iron burners are more expensive than their stainless-steel counterparts and need to be well maintained. The usual maintenance practice is to wire brush cast iron burners to remove rust, debris, and flakes. Then you should lightly coat them with vegetable oil.

Aluminum and brass are two other materials used to make burners in natural gas grills. The aluminum is cheaper but brass has the upper hand. Its resistant to corrosion and stains which are ideal properties of a burner.

Infrared Burners

The possibility of cooking food in half the time is mind-blowing, and this is exactly what this new type of burner does. Infrared burners reach well above 700 degrees F quickly, that charring steak on the outside with a nice raw middle is now possible. But how does it work?

Infrared burners focus flame on the ceramic tiles with microscopic holes. This, in turn, converts the flame’s heat to infrared energy, which is the same as what the sun emits on a cold, windy day. The heat from these burners is higher and more persistent than in standard burners so that you can cook almost twice the quantity of food in a shorter time.

Conventional grills work by heating the air around the food. But in these burners, metal screens are used to get infrared energy from convectional heat. The flow of air is stopped by the metal screen or ceramic diffuser, which radiates infrared heat instead.

This new technology cooks food evenly and makes grilling more enjoyable. It is particularly good at searing meat and reducing the flare-ups you would get from a conventional burner, but for a high price. You would consume less gas while supplying high-intensity heat with infrared burners.

Side Burners

Side burners are one of the most underused cooking parts of a grill.

A side burner gives extra cooking space and allows for additional types of cooking apart from grilling. You don’t have to go inside to warm or sear your steak. It is right there for you to use to do that. They are useful for cooking vegetables, especially when the normal grill is being used for cooking meat.

A side burner can also be used for frying foods. The odor from fried foods cooked in the kitchen stays inside even with good ventilation systems. Luckily, you can use side burners to fry catfish, French fries, and hushpuppies.


Materials, Quality, and Durability

The materials a grill is made from will determine the overall quality, craftsmanship, and price of the unit you choose. 

A stable and strong setup is ideal, but you still have to play your role in maintaining it. If you are in doubt of the material your grill should be made of, then perform a magnetic test. An excellent grill will be almost non-metallic.

Flavorizer Bars

When natural gas grills were first introduced, they w used lava rocks that were prone to flare-ups. Nowadays, almost every natural gas grill uses flavorizer bars to direct drippings and grease away from the tubes of the burner. The grease from food fall on the bar is vaporized and finally circulated back to the food to give an extra flavor.

The roof-shaped bars are placed under the grates and just above the burners to protect them from grease and prevent flare-ups. Flavorizer bars are made from different types of materials.

Cooking Grates

Grates are the cooking surface and one of the most important parts of your grill. It should be made from a strong, resilient, and durable material that can easily transfer heat. They don’t necessarily have to be non-stick, but food shouldn’t be hard to remove from them either.

The most common grate materials are cast-iron, stainless steel, porcelain-coated steel, or just plain steel
.

Let’s take a closer look at each type:

Steel Grates

Grates made from plain stainless steel are the most affordable kind available. However, these grates come with several setbacks. Stainless steel units also lose most of their non-stick fast although not as quickly as plain steel grates.

If cleaned properly and regularly, stainless-steel units should last for a long time. Avoid plain, rod-type steel grates. They would develop rough and uneven surfaces quickly.

Cast Iron Grates

Experienced grillers usually go for cast iron grates, even though they are heavier. Although cast iron grates take a little longer to heat up they can handle extreme heat and retain it for a long time.

Cast iron grates are more expensive than all other types however they can last for years on end. However, one drawback is that they need to be maintained regularly.

Porcelain Grates

You can get two different types of porcelain grates:​ porcelain-coated steel and porcelain-coated cast iron.

Ignition System

When you’ve prepped everything and ready to cook, nothing could be as frustrating as the grill not starting.

Here are the different types of ignition systems.

Hot Surface Igniter

Hot surface igniters are ignition systems that must be connected to an electricity source to operate. Some of these igniters light the main burner without requiring a pilot light, although this is not always the case. They have few parts, which means fewer things can go wrong with them. Host surface igniters are found in very expensive and fancy grills.

Battery Ignition

Battery-powered ignition systems produce repeated, reliable, and hot sparks.They have little step-up transformers in them to increase the voltage. Two of the most common types are the AA and AAA batteries. Battery-powered ignition systems are the easiest to fix. Just remove and replace the batteries when they get bad.

Piezo Ignition

Piezo electronic igniters were one of the first attempts to make a fully automatic system. They come in two types: the pushbutton type and rotary unit.

The former has a wire terminal that connects it to the electrode, while the rotary unit can have up to four wires. This system will get your grill started in no time, and is recognized by its clicking sound.

Warranty

Warranty times differ from manufacturer to manufacturer.

Check the manufacturer’s guide to see all the parts and cases that are covered by the warranty. The shipping and transportation fee for damaged parts are usually free.

Ease of Cleaning

When choosing a grill, I prioritize the units that have removable parts. They make cleaning and keeping on top of maintenance a whole lot easier. 

The burner, flavorizer, cover, and grate materials would determine how often your grill needs to be cleaned.
