Did I miss it, or has there really been nothing posted anywhere about a new firebox design? My dealer just showed us an announcement from BGE about a new firebox design that is being phased in as old inventories are depleted. What I saw was a bad copy of the announcement, but from the picture on the announcement it looks like what they did was something like if you took an existing firebox and made a vertical saw cut down the back of the box. This would presumably allow expansion and contraction and prevent breakage.
There was no word of a similar change to the firering, but then I've always thought that firering breakage was pretty rare, based on the number of posts on the Big Green Egg forum.
So, it should be very interesting to see how the new firebox does in the field. I'm sure we have all wondered about how bad the warantee expense must be to BGE to replace broken fireboxes. Here's to hoping that they have solved the problem.
