Central Heating Air Separator Piping Diagram

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.

Central heating air separator piping diagram.

Dirt separators if cleaned regularly have low pressure loss characteristics important for reducing energy demands and ongoing running costs. 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. An air separator is an in line device that removes entrained air microbubbles that is moving with the flow of the fluid. Air vents should be mounted at any point in a piping system where an air bubble could form.

These air pockets can actually restrict or block flow in a hydronic piping system. They do have a reputation for blocking up with. Hydraulic separators must be properly sized to provide proper hydraulic air and dirt separation. They are different products for different purposes and you can t really compare efficiency between the two.

A new separator is about 20 so it might be worth installing a new one. As 1 et 1 p 1 p 2 fcu cooling primary pumps secondary pumps secondary pumps primary pumps air dirt separators.

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.
