I had no doubts about it: but what about inside the interchange? The galvanized elements are conical so they must be mounted on iron or galvanized elements ... We are here in front of a completely "hybrid" part!
Given the welds there is a great chance that there are 2 "collector" chambers before the stainless steel tubes which start at the 2 welds ...

The interior (the glycol circuit), which must be made of stainless steel, sticks completely to the magnet.
I also wonder...
It is probably a non-magnetic stainless steel, by the way, a pro does not normally weld stainless steel with non-stainless steel ... which seems to be the case here.
The bodies of recent pool heat exchangers are generally made of polymer ...
What weight in all?

I think it will last much longer than that ...
