Weber Spirit E-310 vs Weber Genesis E-325s: Which Three-Burner Weber Fits Your Patio

Where these two differ

Both grills are three-burner Webers with porcelain-enameled cast iron grates, Flavorizer bars and the long Weber warranty, so the question is what the Genesis E-325s adds for its higher price. The answer is heat and room: 39,000 BTU against 30,000, 787 square inches of total cooking area against 529, a dedicated sear zone burner, a taller lid and a sturdier frame with more side table. The Spirit E-310 is the same cooking idea in a smaller box.

This comparison is based on the published specifications and manuals for both grills and on recurring owner feedback. We have not cooked on either grill ourselves.

Heat and searing

Thirty thousand BTU over 529 square inches is a healthy heat density and the Spirit reaches searing temperatures with a long preheat on all burners. The Genesis has more total heat and, more usefully, a sear zone burner between the main burners that pushes one section of the grate hotter than the rest. A steak gets a crust there while chicken finishes gently beside it. On the Spirit, the whole grate is one temperature and the cook moves food around instead.

Cooking space and lid

The Spirit feeds four with room; two racks of ribs or a dozen burgers fill it. The Genesis primary grate is wider and the expandable top grate adds a second level, so eight guests or meat plus vegetables fit without crowding. The Genesis lid is taller, which matters for a beer-can chicken, a turkey or a rotisserie attachment that the Spirit lid will not close over.

Build and footprint

Both share the Weber cookbox and burner construction and the ten-year warranty on the parts that fail. The Genesis frame is heavier, the side tables are larger and fixed, and the whole grill takes more patio. The Spirit has one folding table and a narrower stance, which is the difference between fitting beside the back door and not.

Running costs

Nine thousand more BTU means the Genesis uses more propane per hour when all burners run. For weeknight cooking on two burners the difference is small; for long entertaining sessions it adds up to an extra tank or two a season.

Which one should you buy

The Spirit E-310 is the right grill for a household of four that grills a couple of times a week and has a modest patio. It cooks the same food on the same grates and costs less. The Genesis E-325s is for anyone who entertains, roasts, wants a real sear or simply grills often enough that the larger grate and the better frame are used every week. The price difference buys capacity and heat that a frequent griller notices and an occasional one does not.

Common owner complaints

Spirit owners mention the folding side table flexing under a loaded platter and the smaller lid stopping a tall roast. Genesis owners mention assembly time, the weight when moving it across a deck and grease that collects under the sear zone if the tray is not emptied often. Neither has a pattern of burner or igniter failure, which is what the long warranty covers anyway.

Our verdict

The Genesis E-325s is the better grill and the Spirit E-310 is the better buy for a small patio and a small household. Decide by how many people you cook for and whether a steak crust matters, and both will last a decade.
