This lecture explains the importance of low water temperature heat emitters and distribution designs in modern hydronic systems. It covers the relationship between heat source efficiency and water temperature. It shows and describes several types of heat emitters that can operate at low water temperatures. It goes on to describe homerun distribution systems and modern variable speed circulators. It concludes with three examples that put all the sub-assemblies into complete systems.
