Imperial unit of thermal conductivity: BTU.h-1.ft-1.℉-1: Dimensional formula: M 1 L 1 T-3 Θ-1: Thermal Conductivity Of Metals. Following is the table giving information on thermal conductivity of metals when the temperature is measured in °C. Metal:
I looked up the wall thickness of 5/8 in. tubing (.040" or .00333 ft.) and the thermal conductivity of copper (231.2 Btu/ft hr degree F). Using the surface area of 39.3 square ft. and a delta T of 60 degrees F, I calculated an exchange rate of 163.7 million Btu/hr.

defined as the amount of heat, in BTU’s per hour, that will conduct through one square foot of one inch thick material when the temperature differential across the material is one deree g Fahrenheit. 1 Thermal conductivity is often denoted as k or
Thermal conductivity PEX-a pipe does not sweat like copper, due to its very low coefficient of thermal conductivity of 0.219 Btu/(hr•ft²•°F). Copper has a coefficient of thermal conductivity between 300 and 400 Btu/(hr•ft²•°F), depending on wall thickness (type K, L or M).
Thermal conductivity measures a materials ability to allow heat to pass through it via conductance. The thermal conductivity of a material is highly dependent on composition and structure. Generally speaking, dense materials such as metals and stone are good conductors of heat, while low density substances such as gas and porous insulation are ...
