What is the term for the piping system used to transport heated water in hydronic systems?

The term for the piping system used to transport heated water in hydronic systems is hydronic piping. This type of piping is specifically designed to efficiently move heated water throughout a building for the purpose of heating spaces, such as through radiators or underfloor heating systems. Hydronic systems rely on this piping to circulate water that has been heated by a boiler or other heating source, and it is crucial for maintaining effective temperature control and comfort in heating applications.

Radiant piping refers generally to the network that includes tubing for radiant heating, but it does not encompass the entire hydronic system as hydronic piping does. Condensate piping is utilized to carry the water that results from the condensation of steam or other gases and does not apply to heated water transport. Drainage piping is meant for removing waste water and does not play a role in transporting heated water for heating purposes. Thus, hydronic piping is the appropriate and specific term that describes the system used in these heating applications.
