What's inside an Aerjec?

[qazwsxedc]

I'm asking because the one in my central heating system isn't installed in accordance with the drawings available at circulatingpumps.net Now, if it just contains some baffles to slow down the water flowing through it and allow air to collect and escape at the highest point, then it won't make a difference. If it contains a float or valve then it will.

Does anyone know or have an old one to cut up? The gurgly CH is driving me nuts!

Any answers appreciated.

Its just half a baked bean can with different pipe connections coming from it--it hasnt got a float valve,it's an air seperator.

Old or obsolete system, introduced because plumbers were unable to understand heating systems, call a decent heating engineer he will re-pipe it in about twenty minutes.

The idea is simply that as the water passes through the device it hits a fixed plate which separates any air bubbles that are suspended in the water allowing them to rise and escape through the vent.
The free added bonus with one of these devices is that the vent and feed are attached in close proximity. This is an ideal way of preventing the system from pumping over or sucking in at the vent.
If your system is gurgling it could be because theres air trapped somewhere nearby OR if you are sure the noise is coming from the de-aerator then it is quite rare yet still possible that the pump is sucking in air. If this is the case an inspection of the pump will reveal a black coloured inlet and a rusty red coloured outlet.

(Yawn) an open vented system, i.e tanks in loft,etc. When coming across these setups the simple solution was to tie in the cold/vent before the pump. No Bigee
