Hi There can anyone help me. the other day two of my radiators seemed to be a bit warm rather than hot like the others. so i decided to bleed them and they got hot in a matter of minutes. the problem ive got now is earlier today i put the heating on and the boiler started to make thumping sounds and now heating wont work. first of i thought there must of been a air lock somewhere so i bled all the radiators and still it wont work. can anyone help many thanks.
