Central Heating Air Separator Piping Diagram

An air separator is an in line device that removes entrained air microbubbles that is moving with the flow of the fluid.

Central heating air separator piping diagram.

Insure that piping between the air separator and the plain steel expansion tank is pitched at least 3 degrees to facilitate the migration of captured air. So it is quite likely that the way it is currently installed is contributing to the pumping over. Integrated piping systems zheating cooling fire protection condenser water trade. Hydraulic separators must be properly sized to provide proper hydraulic air and dirt separation.

They do have a reputation for blocking up with. They are different products for different purposes and you can t really compare efficiency between the two.

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

This is a diagram of the obsolete one pipe pumped system. The design of the air separator means that is has to be on its side with the side vent pipe at the top to work properly.
