Hydronic heating is any type of heating done through the circulation of heated liquid. It is sometimes called radiant heating, although in industrial use radiant heating can also refer to other types of heating systems that use hot surfaces. A hydronic system heats liquid and then pipes it to terminal points, where it raises the temperature of an object, such as floorboards, radiators, or baseboard heaters. The heat radiates off the object into the room, raising the temperature of any object the heat touches without raising the temperature of the air between.
Hydronic heating can be found in many types of buildings, and they are becoming popular for many industrial applications. If you are planning on a heating installation for your industrial facility, you may wish to consider using a hydronic system for a number of reasons:
