The hydronic heat exchanger is popular in water to air or forced air heating systems. As water is sent to the heat exchanger, it is moved throughout the duct system by an air handler that pushes heated air at the right volume into each room to ensure proper heating within the home. Booster coils can also be utilized to super heat air in large duct systems where a single air handler is used.

The oldest type of hydronic heat exchanger is the one pipe system. This system sends heated water to the radiators and then uses gravity flow to return condensed water back to the boiler for reheating, but the disadvantages are that clanking sound familiar with those old cast iron models from years ago.

The most common hydronic heat exchanger system is the 2 pipe system. This system sends hot water from the heat exchanger to the radiators to heat the rooms; a return pipe sends the water back to the boiler to be reheated. This system is the most quiet and efficient of the 2 systems, but all of these systems require a bleeding system to remove air from the pipes and a pressure leveling system that helps keep the water level constant to avoid hissing and knocking noises that are common with water and steam heating systems.
