Huum stones exploding

We had a similar thing happen where the stones started basically turning into sand, and Huum sent us new stones. The new ones have held up well so far. Also had some of the heating elements get damaged, and they sent new ones along with this new metal part that holds them in place better.

Good to hear. How long on the new elements so far? In my case the root of the problem may have been that the structure, they call it air-channel, smothered by the rocks, caved under heat and rock pressure. (The gauge of steel on the channel is not enough to allow for some healthy margin of error, it seems.) This brought elements closer and caused runaway heating and near fire. Watch for excessive sagging of rocks over time. This may be a telltale sign that the caving has started. I hope it will not.

One other factor. Do you have an air tunnel? I do.

I do. It got crushed and mangled by the heat and stone weight/intrusion on the original heater.
