Try turning your boiler stat down, you have already said they are hotter, if the boiler was set on max temp to do the flush it might not have been turned back to where you had it set

Yeah i noticed this last night actually. The setting for both rads and water was on max which without going looking would be a number 6. I've turned them both down to their economy setting which i think is a number 5.
