There is a new photo of VXL on their instagram. This is the first time we can see the new bamboo nicely. Its indeed very different.
The restrictions seem made differently. The outside of the bamboo is no longer straight, but narrows with them.
I think this can protect it against heat shock. I think this bamboo wouldn't break like in my old Cloud.
It seems a bit more mechanicaly fragile at the bottom - but the bottom does never get stressed anyway.
The two heating/mixing chambers went below the heater.
I think this doesn't entiraly mean they are not working anymore. I think the heat from the heater can reach the first and second one.
Maybe they don't get exactly on the temp anymore, but as preheaters, i assume their function probably continues.
The new main heat exchanger is just a wide hollow tube. After being pre-heated in these chamber, this should do the real magic now.
What magic is still a mystery to me. i only have experience with the Cloud which only uses the chambers.
