Weber Summit S-420 Grill Review

I shopped around a lot before deciding on a Weber Summit s-420 Propane grill. Much of my decision was based on past experience. I owned a Weber Genesis Grill for 15 years then passed it on to a young friend who got another 5 years out of it. The replacement,  a premium…read expensive…all stainless steel grill was a huge mistake. It was hard to keep clean and no matter what I did flare ups were all too common…ok if you like blackened steaks.

So I was really excited when my new Weber grill arrived in a huge box…I couldn’t wait to set it up.

That was a month ago..since then I have grilled more hot dogs, big steaks, kabobs and vegetables…no blackened food.. just nicely grilled meals with a terrific sear on the steaks. Plus it seems to use less propane than my previous grill for better results.

Weber S-420 Grill

The S-420 is a really good looking addition to my deck but, it is way more than a pretty is a serious grilling machine.Take a look at these specs:

  • Four 12,200 BTU stainless steel tubular burners
  • 538 square inches of primary grilling space for a total cooking area of 650 square inches
  • 48,800 BTU output from the main burners
  • 12,000 BTU side burner under a flush mounted cover
  • Double layer stainless steel hood with built in thermometer
  • On knob piezoelectric igniter for individual burner ignition
  • 304 stainless steel, cast aluminum and steel frame construction
  • Stainless steel rod cooking grates and “flavorizer” bars
  • Handle mounted 3-LED battery powered grill light

I was really impressed with the even heating across this grill..this is important because with even heating you can count on consistent results no matter where on the grill you place the food. I measured the temperature at 9 different places and found the temperatures to be amazingly consistent. Notice the difference between the grill and a foot above it on the built in thermometer. I think it is time for Weber to find a way to measure and display the temperature at grill level…where it counts

This consistency plus Weber’s “Flavorizer Bars” make for terrific results. The “Flavorozer Bars” are v shaped slabs of stainless steel that sit on top of the burners. They get hot enough to vaporize drippings for a nice smoky flavor with no flare ups. I do however find that the side tables get so hot they are pretty much useless for anything but hanging tools. I suppose when I barbecue in the winter it would be handy to keep plates warm.

Weber Summit S-42- Propane GuageThe S-420 is also a solid grill…nothing rattles on a Weber…and it has a number of neat features and one gimmick. I like the piezoelectric igniter built into the knobs which also provide a ide range of control of the burners…grat for cooking delicate foods. I love the pushbutton LED indicator showing how much propane is left. The LED grill light is a bit of a gimmick, it really doesn’t provide enough light to do much more than show you where stuff is on the grill.

The Summit series is the top of Weber’s line of gas grills and it shows in this solid good looking and functional grill. It doesn’t come cheap however at $1799 you pay for the Weber name which means 24/7 support 365 days of the year, a 10 year warranty and the best customer service in the business.

The Weber S-420 is a great grill available in LP or NG versions. It is the grill to buy if you want great performance for a long time. Weber Grills are the Gold standard and practically never break..and if they do you can expect great support.

    I have a Weber Genesis that I am thinking of changing. I am very disappointed by uneven cold spots and the cumbersome burner dial knobs on the side, eliminating badly need surface space.

    It seems that this model was thought out well! I’ll be grappling with the thought of paying a $700 premium for this, however.

    Thanks for your great product reviews!

      Thanks for the comment. Based on my experience you can’t go wrong with the Summit. I surprised at your issues with the old one which would have been 25 years old now was a solid well performing grill as is my brother’s brand new Genesis.
