[RE-wrenches] SHW collector absorber plate issue

[August Goers]

Hi Wrenches,



We have several installations from a few years ago where we're noticing
strange discoloration around the corners of the absorber plate:





I'll keep the manufacturer anonymous at this point but I'm wondering if any
of you have experience with this and if so what the problem might be.



Thanks in advance for your wealth of knowledge.



Best,



August
