Heat Exchangers: Copper vs. Stainless Steel - AccuServ
I was wondering if anyone knew how long a boiler would last if it used copper tubing for the boiler circuits ? I have seen many of the copper wound Richard J Smith boilers in several old magazine articles but there seems to be no printed information on how long the tubing lasted in service. In a boiler the conductivity of the metal is

heat transfer, pex vs. copper Hearth.com Forums Home
2010-10-2 · Remember, too, that PEX tubing wall thickness increases a lot with diameter. 3/4" tubing has a wall thickness damned near half again as thick as 1/2". I don't know how much that effects the heat exchange rate but it will be a bigger effect than copper. Lots of speculation about optimum heat exchanger tubing diameter in the past here.
