Which pipe materials are typically used for hot water distribution?

The choice of copper, CPVC, and PEX as pipe materials for hot water distribution is rooted in their ability to withstand high temperatures and pressures, making them suitable for this application.

Copper is a traditional material known for its durability and excellent thermal conductivity. It can handle high temperatures without degrading, which is crucial for hot water systems. Additionally, copper is resistant to corrosion, adding to its longevity and reliability in plumbing applications.

CPVC (Chlorinated Polyvinyl Chloride) is designed specifically to handle hot water distribution. It is rated for higher temperature applications compared to standard PVC, and it has impressive resistance to scale and chlorine, which can help maintain water quality. Its lower weight and ease of installation make it a favorable option for many plumbers.

PEX (Cross-Linked Polyethylene) is increasingly popular due to its flexibility, which simplifies installation and reduces the number of fittings required. PEX is also resistant to scale and chlorine, does not corrode or develop pinhole leaks, and can expand to accommodate freezing conditions, making it an excellent choice for hot water systems.

Using these materials allows for efficient and reliable hot water distribution, making them the preferred choices among plumbing professionals. Other materials listed in the options can have limitations regarding their performance with
