Hydronics is a means of heating and cooling using a fluid as the heat transfer medium. Historically, in large-scale commercial buildings, the Heating, Ventilating and Air-Conditioning (HVAC) systems utilize water-based hydronic designs. In this interactive online course, we will describe the differences among the different types of hydronic systems. We will discuss expansion tanks and their role in a hydronic system. We will also discuss make-up water systems, air elimination, meters, and gauges.

The following key questions are answered in this module:
What is hydronics? Hydronics is a means of heating and cooling using a fluid as the heat transfer medium.
What is the difference between an open system and closed system? An open system has some point in the system open to the atmosphere, while a closed system is not open to the atmosphere at any point; the fluid is never exposed to anything outside of the system itself.
What are some examples of heat source devices? Heat source devices include boilers, fluid-to-fluid heat exchangers, and water-source heat pumps.
Where is the pressure typically lowest in the system? The lowest pressure in a system is typically at the expansion tank.
What are common causes for leaks in plate heat exchangers? Causes for leaks can be corrosion, excessive pressure and material fatigue due to repeated temperature fluctuations.
