The Spirit line is Weber’s entry level and the least expensive in the catalog. Made in China, they are the subject of criticism from Weber devotees who have always prized their high quality and their American made emblem. The E-210 has two burners, while the E-310 and E-320 have three burners, running left to righ and lined up from front to rear. This configuration is especially good for rotisserie cooking, but not as convenient for 2-Zone or Indirect cooking as when the burners line up from side to side. But it can be done.
They all have a small stainless work shelf on the left, and on the right shelf are the burner controls and tool hooks. Ignition is battery operated electric. The main grates are porcelain-enamel coated. The lightish hood is made of porcelain-enameled steel and the handles on the magnetically-held lower doors are plastic, as is the handle on the hood. The E models are black porcelain enamel, SP models are stainless steel.
The E-210 has 350 square inches of primary cooking surface and a 108 square inch removable warming rack for 458 total square inches, enough for small family grilling. Two stainless steel burners put out 26,000 BTU, and the design features well-placed, well-measured vents that let air flow without the draft snuffing the flames.
The E-310, SP-310 have three burners rated at 36,000 BTUs, 424 square inches of primary cooking area and 112 on the warming rack, giving you a total of 536 square cooking inches.
The E-320, SP-320 are the same as the 310, but includes a 12,000 BTU side burner hidden in the left side table.
