Is a copper / copper heat exchanger the solution for corrosion?
A copper/ copper heat exchanger basically eliminates only one potential cause for corrosion, galvanic reaction. A copper / copper heat exchanger is still vulnerable to the corrosive effects of the environment. Once again, independent tests show that a bare copper / copper heat exchanger will not resist corrosive damage as well as a less-expensive aluminum / copper coil treated with Blygold coatings.
