What must be ensured regarding radiant piping installation in floor heating systems concerning visibility?

In a radiant flooring heating system, the installation of the radiant piping must be clearly marked to ensure that it is easily identifiable. This is important for several reasons. First, marking helps to prevent accidental damage during maintenance or renovations, as personnel will be aware of the location of the piping. Second, clear markings can facilitate troubleshooting and repairs if issues arise with the heating system, making it easier to locate individual pipes or loops.

Maintaining the pipes is essential for their functionality over time but does not address the visibility aspect. Concealing or obscuring the pipes would negate the purpose of marking them, as they would not be easily accessible or identifiable, which could lead to complications in future work on the floor system. Therefore, ensuring that the radiant piping is clearly marked is crucial for safety, maintenance, and efficiency in managing the heating system.
