Explanation of Hot Water Heating Systems | Hunker

Water is heated by a boiler and circulated throughout a building--usually homes (older homes, especially)--through a series of pipes that heat radiators that give off heat. The heat transfers to the air in the room. There are three basic types of hot water heating systems: gravity flow, pumped and baseboard convection systems. Advertisement.
