What type of piping is used in a hydronic heating system?

In a hydronic heating system, hydronic piping is specifically designed to transport heated water or steam throughout the building for space heating purposes. This type of piping is typically made of materials such as copper, PEX, or steel, which can withstand the pressure and temperatures associated with hot water heating. Hydronic piping systems are efficient for distributing heat, as water has a high heat capacity and can maintain a stable temperature throughout the system.

Drainage piping is intended for removing wastewater and is not suitable for carrying hot water. Hydraulic piping is often related to systems that use fluids under pressure for transferring energy but does not pertain specifically to heating applications. Vent piping is used to facilitate airflow in drainage systems and is also not applicable to hydronic heating. Therefore, hydronic piping is the appropriate choice for this context, aligning with the functional and material requirements of the system.
