Help identifying parts

[Brian Hartshorn]

My daughter has moved into a house and we are trying to get to grips with the heating system. Can anyone please tell us what the thing in the attached phots is and what it does.

Many thanks.

Looks like an air separator also called by its trade name airject they are prone to scale up ....some experienced heating engineer will be along shortly to correct me and tell you more about it....regards Turnpin

It's a turd, that causes lots of problems. Definitely cut more out than installed.

I fitted LOADS of Aerjecs. They did not generally scale up, but sludge or fungal goo collected at the cold feed.
I never recall any call backs to any of mine. But EVERY system (actually few systems complete, but many changeovers) I fitted was cleaned thoroughly, including the header tank.

Actually, and pedantically, that is not an Aerjec, it is of the Tower design, but there are many clones.

Thank you all very much for the info.

I would worry more about the plastic pipework in front of the air separator and anything else done by whoever installed it.
