Hi Guys,
Would love your feedback on an issue I had. Had a flat plate that worked fine for about 8 years transferring into a pressurized cast iron rad system. Customer said it gradually stopped heating well.
Took it apart, found this grey scum on the outlet of the owb side, indoor boiler side is clean.
What is this stuff and how do I get rid of it? I'm guessing it's a bacteria type thing?

I'm not saying it's the same thing, but I have found that same type of goo in my pool skimmers when I open it in the spring. The pool folks said it was a mold of some kind.

Is there glycol in the OWB?
-
No. There is not.

Hmmm... Looks a lot like the scum from untreated glycol. Did you test the water by chance?
