Central Heating Air Separator Piping Diagram

So it is quite likely that the way it is currently installed is contributing to the pumping over.

Dirt separators if cleaned regularly have low pressure loss characteristics important for reducing energy demands and ongoing running costs. These air pockets can actually restrict or block flow in a hydronic piping system.

Excessively high flow rates will impede these functions. There are a few systems like this remaining in use but generally they are approaching 50 years of age or fitted by a diy installer with a very old book of how to fit central heating. An air separator is an in line device that removes entrained air microbubbles that is moving with the flow of the fluid. A new separator is about 20 so it might be worth installing a new one.

Air vents should be mounted at any point in a piping system where an air bubble could form. They are different products for different purposes and you can t really compare efficiency between the two. This is a diagram of the obsolete one pipe pumped system. Hydraulic separators must be properly sized to provide proper hydraulic air and dirt separation.
