What does hydronic piping typically transport?

Hydronic piping is designed specifically to transport heating fluids, such as water or other heat-transfer liquids. In hydronic heating systems, water is heated in a boiler and then circulated through pipes to radiators, baseboard heaters, or other heat emitters to provide warmth to a building. This method is widely used in residential and commercial heating applications due to its efficiency and effectiveness in distributing heat evenly throughout a space.

The heating fluids in these systems are crucial for maintaining comfortable indoor temperatures, especially in colder climates. The properties of water, such as its ability to hold and transfer heat, make it an ideal medium for these systems.

While other options like cooling agents or refrigerants may be part of different HVAC systems, they do not pertain to hydronic piping specifically, which focuses on heating applications. Wastewater is transported by plumbing systems that are entirely separate from hydronic systems, which are specifically intended for heating purposes.
