Weber Spirit 310 vs 315: Comparing the Features & Performance of the Gas Grills

Weber Spirit 310 vs 315

Best of Pricing

Well, the two gas grills aren’t exactly cheap to own. The Weber Spirit II E-310 has a $570 price tag, while the Genesis II E-315 sells at $1,031. But then, is the extra four hundred bucks on the Genesis grill worth it?

Winner: Weber Spirit 310 grill as it saves you over four hundred bucks


Unfortunately, Weber delivers Spirit 310 and Genesis 315 with only the basic accessories. That includes the stands, caster wheels, side tables, cooking grates, lid (with integrated thermometer, and the GS4 grilling system.

The GS4 system is the whole unit of the infinity ignition, burners, flavorizer bars, and grease management unit. But the burners are only three across, and no infrared rear burner like the Napoleon Prestige grill. So, you can’t use the rotisserie and main grill at the same time.

Speaking of the rotisserie, you’ll have to purchase the system separately since Weber doesn’t provide either of the two grills with one.

Winner: None as Weber offers the grills with only the main grilling kit

Best of Design/ Style

Even though beauty is in the eye of the beholder, the Weber Genesis II E-315 is no doubt a clear winner here. It has a pretty lovely expression while even far from the inclusion of the cabinet doors and stainless handles that has blended perfectly well with the whole system.

The bottom part of the Genesis grill also has an enclosure all-round and the interior is large enough to hold your LP/ NP gas tank. Then, the lid has a 10-inch height, which makes it possible to barbecue or roast on the rotisserie without a hassle.

On its end, sadly, the Weber Spirit II E-310 has a relatively shorter grill lid, which makes it hard to find the right rotisserie. And also the bottom space looks too basic as it’s an open cart without front doors or side enclosures.

Winner: Weber Genesis 315 as it’s more appealing, plus has a taller grill lid and enclosed bottom

Cooking Area

If you have a larger family to be grilling for, the Weber Genesis II E-315 will also be the best choice. Of course, the difference with the Spirit II E-310 isn’t significant, but the extra 100 sq. inches still matters.

The top warming rack area of the two grills could also work as a secondary grilling area for things like baked potatoes, asparagus, hotdogs, and buns. But even there, the Genesis grill has more space by about fifty square inches.

Winner: Weber Genesis 315 has about 138 sq. inches more cooking area than the Spirit grill

Burning Fuel

When we now compare Weber Spirit II E310 vs Genesis II E315 on the fueling, they both rely on gas to cook your recipes. And you can get a version of either Liquid Propane (LP) or Natural Gas (NG), but not both.

Moreover, the two grills have an integrated fuel gauge to let you know when your gas tank is drying up.

Winner: Both as they run on gas and also have a fuel level gauge.

Grilling Heat

First up, Weber innovated the Spirit II E-310 and Genesis II E-315 with a three-burner system. Also, the “E” on both gas grills means they have porcelain-enameled cooking grates, which means they’re non-stick. And since the main material is cast iron, they also heat up pretty quickly.

On the Weber Spirit grill, the said heat can go up to 600°F. It also cooks the food in place faster than most pellet grills.

The Weber Genesis II E-315 also heats up steadily but has a total output of 39,000 BTU/ hour, which is higher than the Spirit model. So, you’ll notice it does everything (heating up and cooking) a little bit faster than its counterpart.

Bear in mind that Weber sends all the Spirit and Genesis gas grills with flavorizer bars (removable). These are the V-shaped metal bars lying between the burner tubes and BBQ grates. And they help distribute the heat evenly across the entire grate while at the same time preventing flare-ups.

Winner: Weber Genesis 315 heats up a little quicker as it also has 9000 more heat output than the Spirit 310.

Cooking Methods

Do you want your grill for just grilling steak? I’m hoping not, considering these machines have unlimited capabilities. If it’s our Weber models, the smooth side of the grates handles delicate food like fish, chicken, hotdogs, and even pizza. Then, the other side (has wider spacing) for searing your steak and other foods you’d like to leave some grill marks.

As mentioned earlier, these two gas grills also have a warming rack that you can use for slow cooking. Then, the grill lid has the side slots to pass through a rotisserie when you want to barbecue or roast your meat while basting.

Furthermore, the flavorizer bars I’ve just mentioned can help add that “cooked on grill” aroma you want on your dish. And in case the vapor from the drippings isn’t enough, you can get a smoker tube box for the extra smoky touch.

Winner: Both grills can grill, roast, sear (light), warm, and smoke your food

Smart Control

Again, both Spirit and Genesis grills win in this part as they all utilize physical knobs to regulate the heat in the cooking area. And also they’re compatible with the add-on iGrill 3 smart thermometer that makes it possible to monitor your foods via a smartphone app.

Even better, Weber claims you can set the desired temperature of your meat, and the mobile app will notify you once reached.

Quick Common Questions

How much does a Weber Spirit 310 weigh?

The Weber Spirit 310 is one of the simplest yet bestselling gas grills from the brand. It has a total weight of around 115 pounds, thereby you can mount a 20lb propane gas tank without toppling it over.

Which Weber Spirit is the best?

In general, all Weber Spirit grills are great since it depends on what you want to accomplish at the end of the day. But from the available catalog, my top three options come down to:

Is Weber Spirit the same as Genesis?

No, Weber Spirit isn’t the same as Genesis grill. They’re two different grill series, but they share quite a number of features. Such features include the GS$ grilling system, porcelain-enameled cooking grates, burning fuel, gas gauge, vaporizer bars, and the iGrill 3 support.

To Conclude:

Weber is a great grill, both on pricing and performance. In our Weber Spirit 310 vs 315 comparisons, we’ve mentioned the former saves you over $400 to buy- and that’s the regular price. Yet, the tool still grills as good as its counterpart while utilizing a relatively smaller space.

Regardless, the Weber Genesis II E310  is still my favorite pick for the enclosed storage space for grilling tools and the gas tank. We’ve also seen it heats up faster and also the lid is taller enough to use a rotisserie with a compromise.
