Try bleeding the radiators of air. If that doesn't work, take radiators off and wash them out. If the radiators aren't balance correctly you will have heating problems.

Hi sean
realy dont no if the boiler is ok, the rads that dont get hot have just been replaced with new ones because we thought that it might be because they were old, and thats why they did'nt get that hot either,
thanks look forward to hearing from u.

if the boiler is ok then the fault lies in rads poss trvs or full of sludge take the rad trv heads off check pins have movement so they open check heating again
