What type of oil line is recommended to be used when buried in concrete?

The recommended type of oil line to be used when buried in concrete is a covered copper oil line. Copper is known for its durability and resistance to corrosion, which makes it an excellent choice for environments that can expose the line to moisture and other elements, like concrete. Furthermore, covered copper oil lines provide additional protection against physical damage due to the surrounding concrete and soil, ensuring the integrity of the oil transport system over time.

Using copper lines also ensures that proper connection methods can be employed, as copper can be easily soldered or brazed, providing leak-free connections. These qualities extend the lifespan of the installation and reduce the risk of failures, which is crucial in maintaining safety and efficiency in oil heating systems.
