Air lock or some other circulation problem

Does the air keep coming? If so it must be coming from somewhere...

Air lock on the return . Turn off all other radiators in house , fire up and see what happens

 

[stevemart3]

no stops water runs clear

will try that next week thnks

flow gets hot rad cold

 

[Dannypipe]

You prob just need to balance the system...which in effect means diminishing the flow to one so that water will flow to the other. Remember water is lazy and will always take the easiest route.
