WebSep 26, 2024 · The EngineeringToolBox website states that copper is 400, PVC is .19, Earth is 1.5 and water is .58 thermal conductivity (k). The Earth and/or water surrounding the tube is 65°F Turbulence creates a ballpark of a 40% increase in heat transfer. I also read that water surrounding a tube is 4x times faster at transferring heat than the earth. WebThe thermal conductivity of a copper system is 2,500 times that of a FlowGuard CPVC system, and FlowGuard CPVC thermal conductivity is about 30% better than other plastic pipes. The improved insulating characteristics associated with FlowGuard CPVC can generate substantial long-term savings for an energy conscious homeowner or tenant.
