Purpose statement:

The purpose of this course is to recognize how effectively hydronic equipment relates to the total system is determined by its capacity to deliver or dispel heat or cooling efficiently.

How effectively hydronic equipment relates to the total system is determined by its capacity to deliver or dispel heat or cooling efficiently. Piping and pumping are key factors in designing and building an efficient system. Beyond piping and pumping, there are numerous components involved in a hydronics system that determine its effectiveness. This course will examine the sector’s various components and put your water-based knowledge to the test.

In HVAC Hydronics, What's Not Directly Measured is Not Directly Controlled
Flow control need not be as difficult as it is sometimes perceived to be.
Steven G Liescheidt P.E., CCS

Sizing Hydronic Systems Is Truly a Balancing Act
Balancing is not an expense but, rather, an investment in indoor comfort and energy efficiency.
Amit Bhansali P.E, PMP, CEM, BEMP and Luciano Belo P.E

Take Control Of Your System With Differential Pressure Control
The ultimate goal of every heating and cooling installation is to provide the desired indoor climate at the lowest possible energy cost. In practice, however, even the most sophisticated controllers don’t always perform as promised.
Bjarne Andreasen

Optimizing Hydronic Flow
Water is a much more effective way to transport energy around a building than air, but it is not without its struggles.
Mike Davis P.E. and James Regan
