Does your system layout meet the minimum requirements of the MI's, I can't tell from your drawing.
If you repipe like this, it will never draw in any air. It's a combined feed and vent and as long as your boiler MI's allow it, then this may be the answer to your problems:- View media item 29821

thanks for your suggestion the local company was suggesting combining the vent and feed, but i didnt really understand it, so i went with the air jec (although that turned out to be the wrong thing) were to i find the messurements ?

thanks

 

[helptavner]

from the top of the boiler to the top of the water level it states max 30.5m min 150mm

thanks

 

[helptavner]

so you think combining the vent and feed is the best suggestion ?

thanks

Since the boiler is new simply go to a sealed system. An easy kit to fit.

A header tank has no place in a modern heating system.

I never fit vented boilers.

Is it air or hydrogen (search the archives)????????

Professionals make a suggestion but you ignore it and buy something else?

Could be that you wanted a free diagnosis?

Did the local company come and examine your system?

If so how much did they charge?

combine vent and feed ?
sealed system ?

Sealed - unless the pipework is mostly inacessible - you can get leaks due to the extra pressure

 

[helptavner]

^^ is that a better suggestion that the combine vent and feed if so why please ?

 

[helptavner]

does my aerjec not combine the vent and feed anyway ?

No, but it is better than a combined vent and cold feed and would stop air being drawn in or pumping over IF installed correctly.

Your diagram isn't clear; you could check that the Aerjec has been installed correctly.

Combined F/V or seal it as suggested. Either way it will solve your problem. If you are worried about leaks(I can see from previous posts of yours) that you are, then don't go down the sealed route.
The aerjec does combine the F/V, but it leaves an open vent for air to get in. The other methods don't. Over and out.
