Air problems in Worcester Bosh Condencing boiler heating

[stuartmac]

Hi

Been to a property where the galloping Cowboy has done his stuff, started with a call about 2 leaking rad stems then went onto new boiler fitted in loft 37KW!!! condecing pipe up hill into stack not flushed patches on rads, constant air in system customer constantly bleeding rads but upstairs rads patchy as if needs flushing not a problem will get he camco on it, however never had a problem with constant air in combi heating any views as need to take system down to fix radiator tails is this just about balancing when bringing it back up??

new sytem and no inhibitor would lead to loads of air till it all settled down of course. only a thought.

probably a leak. Constant bleeding of rads shouldnt take place on a sealed system.
Auto air vent leaking? Rad valves? prv? Didnt flush cleaner from system?
probably find it after camco job.
