Describe the function of an air separator in a hydronic heating system.

An air separator in a hydronic heating system serves the crucial function of removing air trapped within the system. When air accumulates in the pipes, it can create pockets that hinder the flow of water, reducing the overall efficiency of the heating system. This trapped air can lead to inadequate heating, noise, and even potential damage to components due to air binding.

By effectively removing air, the air separator allows water to circulate more freely, ensuring that the hydronic system operates at peak efficiency. This removal of air helps maintain consistent and effective heating throughout the entire system, which ultimately enhances the comfort level in the space being heated.

In addition to improving efficiency, eliminating air from the system reduces the likelihood of corrosion and extends the lifespan of the system components, contributing to a well-functioning hydronic heating setup.
