Help. Should there be a vent pipe after the boiler and before the pump.

I think my heating system is sucking air in through vent pipe.
My heating system is as follows, boiler, pump, motorised valves then I think the vent pipe is after these. Does this sound wrong. I've taken a picture but Iam having trouble uploading it. Thanks

That's a sealed system man- prv on the boiler. Must be an expansion vessel????
If it is open vent you got trouble coz the vent will connected after the valves or somewhere by your hwc off the return!

Cheers man, Iam new to the house. I think it was a sealed system converted to open vent as there is a tank in the loft. Also there is a back boiler stove in the house. Iam thinking of disconnecting the back boiler(getting a plumber) and going back to sealed. Would this stop air getting into the rads.

It will
