I was walking through a construction site the other day and low and behold found what I think is a boiler heat exchanger. It looks just like a CFC but with the internal pipe being 1/2 and the external 3/4. then a gray foam wraped around that. I checked it for leaks and it seems to be intact. has anyone ever used one of these? or know anything about them? I'm in need of a new CFC and thought maybe this would work.
