The Energy Efficiency Of A Hydronic Heat Exchanger

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.The hydronic heat exchanger is also 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.In situations where space is limited wall mounted heat exchangers can be used to maximize space as well as add reinforcement in larger applications where constant heat or temperature regulation is needed. Stainless steel is commonly used in water tanks and in the bodies of hydronic heat exchangers as they hold heat well and when coupled with copper elements provide excellent heat transfer.Additional advantages of a hydronic heat exchanger is the multiple uses available for homeowners, such as providing hot water for bathing, cleaning clothes and dishes, as well and heating swimming pools, hot tubs and many other domestic needs. Known for their superior heating ability in industrial situations this low cost solution is also commonly used for air cooling and driving commercial refrigeration in larger commercial buildings.This highly efficient heating solution is considers a popular “Green” energy alternative when coupled with a wood burning furnace, totally eliminating the need for electricity and fossil fuels. There are a number of tax credits and rebate incentives available for using this energy efficient heating solution. This can offset the installation and cost of purchasing a hydronic heat exchanger, making the return of investment rapid, and one of the most popular choices for home, business, and industrial heating and air cooling solutions available.
