I think it’s a mixture of both hot water and how it’s strapped in , although I haven’t seen it I’m guessing that the straps are going over the tank but not frame , the two top edges are being pulled in once the tank gets hot .

My same tank has done it’s own thing , half of the top has bowed in and half has bulged up !

That is bang on mate.
The straps are cris crossed across the top and ratcheted tight. When the waters hot and the tank goes a little pliable, it crushes down.
I will not heat the water so hot and if it continues I will change the set up.
Thanks to all those who contributed and to the mods on my request removing some comments
