PEX pipes have become a reliable alternative to copper pipes that we were used to. One of the main reasons for this is their impact on the environment.
For Their Properties
PEX piping helps save energy as it doesn’t readily transfer heat like copper. The research mentioned above also confirmed that PEX materials and their low thermal conductivity mean these would help maintain the temperature of hot water for a longer time. It also means that it has more resistance to condensation on cold water lines compared to copper.
When it comes to their lifespan, plastic is known to last more than a hundred years, which makes PEX piping ideal for long-term uses. Copper and other metals might be durable, but you still need to change them every couple of years. This is due to leaks and in some instances, corrosion. Moreover, PEX is more affordable, which makes it a practical option for various piping applications.
For Their Applications
According to this research, replacing copper pipings with PEX resulted in several environmental improvements. First, PEX greatly reduced the emissions to air, water, and land. Second, it helps improve human health. Copper and other metals pose human health issues if they are in high concentrations. Based on this study, switching to PEX piping improved human health related to cancer by 99% and human health not related to cancer by 42%.
Another significant effect of switching to PEX is the 96% reduction of the chances of eutrophication. This process involves the increase of mineral nutrients, which includes phosphorous and nitrogen to the water or soil. This can lead to undesirable changes in the ecosystem.
Moreover, hydronic radiant cooling and heating systems that use PEX piping on the ceilings, under the floors, and in the walls to transport cool or warm water set up an indoor space are also sustainable. They are known to enhance interior environmental quality. They also reduce the need for typical HVAC systems that need more energy to function. Also, these systems work great with renewable energy sources, like solar and geothermal energy sources.
