hi guys , need help to get these rads working again,the story goes shut off all rads fitted new towel rad in bathroom unfortunately had to break into the system to re position( lost a bit of water in the process) the valves due to size no probs .allowed the new rad to fill with water switched on the ch all rads hot except 2 the one nearest the ch boiler theother the farthest away .the system is in micr 8mm me think there is a sequense of bringing it back on after loosing that water .I have vented the boiler :oops: :?: [color=green][/color]

It's airlocked, try draining and refilling. Still no luck ? remove problem radiators and pull each one through by opening valves and allowing water to flow into a bucket until the air escapes.
