Explanation of Hot Water Heating Systems | Hunker

Explanation of Hot Water Heating Systems. Hot water heating systems are built around the premise of radiant heat. 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.
