Objective 2

11

Hydronics

“Hydronics is a term that was introduced in the 1940s to refer to a system of heating or cooling of an internal area using fluids in either vapor or water form. “

12

Hydronics

“These fluids are then circulated throughout a series of pipes or tubes to produce a desired room temperature.“

13

Hydronics

“Although this official term was established in the 1940s, the process of using hydronics or "wet" materials to first heat, then later to cool, a home has been in existence for many years, beginning with the invention of cast iron boilers.”

Objective 3

25

Sources of Training

• Radiant Panel Association

• The ESCO Group

• Manufacturers*

• Others?

* - Caution: Boiler, pump, control, component and PEX manufacturers know and tend to focus on their product’s way of performing.

26

Your training program must

teach the building is a SYSTEM not a

collection of unrelated

components.
