Mend Thorn EMI M30/42/44/54 Heating Radiator Hot Water

I have a Thorn Emi M30/42/44/54 boiler gravity fed system ?

Since fitting a new radiator yesterday I have very hot radiators but no hot water.

My tank in the airing cuboard is cold I have been told it could be an air lock how do I get rid of it.

I cannot find any blead valve.

put a hosepipe from your cold tap to your hot tap then open both tap hot first then then cold it will blow air lock out of system by cold water pressure.
