Hot Water Heating Systems: Transitioning fro

2019-9-9 · Hot water systems have long been a preferred way of transferring heat from a central point (a boiler) to remote spaces or rooms where heat is needed. The first hot water heating systems were gravity systems. When water is heated, it increases in volume; hence it becomes lighter and rises. Simultaneously cooler, heavier water falls. This is the principle on which gravity
