Sorry for so much questions, but I was also wondering if you guys get the cracking sound when the bamboo heats/cools down? Is it normal?
Yes I'm getting it. I think it was louder when it was brand new. But it still happens, I just have to put my ear just above the unit to hear this.
I think it's not the bamboo making these sounds, if it did it would probably be shattered by now.
Also from the cold start I can start hearing this crackling immediately after turning it on.
There certainly isn't enough time for the bambo to be heated up THAT fast. It must be the heater itself making these sounds.
I hear the same kind of sounds from my hairdrier or oven when they are cooling down and heating up. I think its the heater metal parts expanding.
I think we should be probably glad for these sounds as they are maybe protectting the bamboo. If this didn't happen in the heater it could happen it the bamboo afterwards.
Is it ok to trick the auto shutoff? Or how do you keep your unit working for more than 1 hour?
I think it should be ok. Even the old Cloud which got hot all over could be run 24/7 and I think EVOs can be run 24/7 aswell (not inverted).
My EVO doesn't seem to have this timer at all, I had it running for 5 hours no problem.
Also it survived some overheating and is being power heated up and cooled down several times a day.
It is almost a month old (got in on April Fools day) and the bamboo is still airtight.
24/7 runnign can be better for the bamboo as its not heating up and cooling down.
But the unit should of course be able to cool down and heat up a lot without breaking.
I think the heater is programmed to be gentle with the glass.
When my EVO was brand new, it had a little of the "crinkling" sound but it subsided very quickly. I do not get it any more. This is thermal expansion just like you hear on a hot car exhaust after driving. Too much heat too quickly will obviously fracture a bamboo.
When you put your ear near the top you still don't get these sounds? I am getting them still, but not as loud as when brand new.
