Modern Hydronic Heating_ for Residential and Light

Early hydronic systems relied on the buoyancy of hot water to move water between the boiler and the heat emitters. Because of its lower density, hot water would rise upward from a boiler through supply pipes into heat emitters. After releasing heat, the now slightly denser water flows downward back to the boiler, as shown in Figure 1-1b.
