What is the primary function of the baffles in a hot water boiler?

The primary function of baffles in a hot water boiler is to increase efficiency. Baffles are internal components designed to manipulate the flow of water through the heat exchanger. They help ensure that the water spends an adequate amount of time in contact with the heating surfaces, which enhances heat transfer. This means that more heat from the combustion process is effectively absorbed by the water, leading to higher overall energy efficiency in the heating system.

In addition to improving efficiency, baffles also play a role in promoting uniform water circulation, preventing hotspots, and ensuring that the entire volume of water is heated evenly. This contributes to effective temperature management and can result in more reliable performance of the heating system. Thus, their design and placement are integral to optimizing the boiler's operation, ensuring it performs efficiently and effectively.
