Hi.Drained the system today after running for a week or so with radiator flush in. Turned water supply back on but,stupidly only bled upstairs radiators...Now system is not getting warm and boiler only kicks in for short stints. Bled complete system and opened valve by the 3 way / pump.lots of air has come out. Is there a valve on the boiler to release air? Thank you in advance

Depends on the boiler best to turn the boiler stat down eg dial on the boiler and left the pump run or if you can just run the pump on hot water mode for a bit then switch to heating
