Newer 26 heats faster than '01 22

[TheKettleGuy]

Hi folks,

I figured if anyone would know it would be this group. I'm putting together some data for a blog post and I've discovered that my 26 inch Weber comes to temp faster than my 22 inch, which is quite surprising. The 22 is a 2001 model. I was wondering if the wall thickness has changed or if there's a logical reason why this would happen?

For example, using 20 lit coals on a 2x1 snake, my 26 hit 250 degrees in 22 minutes while the 22 took 1 hour to reach 250. (both hit 225 around the same time)

On another cook, it took ten minutes longer for the 22 to hit 225 than the 26 using 8 lit coals to start the snake.

Any thoughts? I don't think the 22 is damaged in any way. If anything the lid doesn't seal quite as well, but more air should increase temps, not decrease. Thanks

never did a side by side, vents are the same size ? but the 26 is bigger so there is more air space ?

Any science knowers want to weigh in? I’m curious as well.

It’s been about a quarter-century since I took heat transfer, but here goes:

The 26” will have a higher volume to surface area ratio. You can get a bigger temperature difference between coals and wall because of the larger size.
