boiler copper tubing water difference on heat conductivity

Thermal Conductivities of Metals - Veolia Water

2015-11-3 · Copper is much more thermally conductive than aluminum, admiralty brass, carbon steel, and stainless steel. So why is carbon steel used so much in heat exchangers? In spite of its relatively poor thermal conductivity, it is widely used for heat transfer piping in process applications because of its low cost relative to other alloys.

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.
