This document provides an overview of hydronic heating systems and concepts. It discusses pipe sizing, circulator pumps, expansion tanks, air elimination, head loss calculation, pump curves, variable speed pumping, the power of temperature differential, basic system design examples, zone valves, reset controls, cast iron boilers, circuit setters, radiant heating, and injection mixing. Key terms like Cv, head, GPM, and Delta T are explained. Diagrams illustrate components and system flow.
